The Requirement to run NovaLCT

NovaLCT is a windows-base software, to to use it properly, you need to prepare the following: 

  • A NovaLCT installation package
  • A Window-Base PC: (Windows 7, Windows 8, Windows 10, Windows 11, or later. Memory: 2GB RAM or above.
  • Ethernet Cable: Gigabit Ethernet with 1GBps

Now that you have a basic understanding of NovaLCT and the preparations are complete, let’s proceed with the step-by-step operation.

Download the NovaLCT Setup Package

The easiest way to download NovaLCT is by visiting the official download page. This is the primary source for the latest version releases.

For your convenience, we have also included the installation package at the end of this guide. You can scroll down and download the appropriate version to get started immediately.

Install NovaLCT

Before installing the software, please ensure the antivirus software is closed. These antivirus programs may interfere with the installation process, causing it to fail or become corrupted.

Here is the simple step you can following: 

  1. Right-click the installation package you just downloaded, and run as an administrator.
  2. Select the language you prefer.
  3. Click “Agree with the agreement” and click “Next”.
  4. Click “Installation Folder” and click “Next”.
  5. Done.

Note: Allow any firewall prompts and ensure the serial port driver is up-to-date, as the installation program will handle this automatically if needed.

Once the installation is complete, remember to re-enable your antivirus software to keep your system protected.

Hardware Connection

Connect the PC to the Sending Card

After you have launghed the Novalct, the next step is to connect the PC to the sending card.

Here is a direct connecting diagram (Using Novastar MCTRL4K as example) to help you follow.

Connection diagram of Novalct with PC and sending card and LED display

Two simple principle you can follow:

  • Using USB or ethernet cable to connect the sender with the control computer where the NovaLCT is installed
  • Using several Ethernet cables to connect the sender with an LED display via output ports

Connect the NovaLCT to the Sending Card

If the previous step went smoothly, NovaLCT will automatically detect the sending card. It will display the status and various parameters of the sender card in the main window. These parameters include port information, SN, device name, etc.

This process requires no additional actions from us. If the main window does not show any information about the sending card, it means you need to recheck the connection or device.

You can check the FAQ section at the end of this guide to see if there is any information related to your error.

In addition, if there is still no signal  or no status update in the main window, you can try to restart the server or reconnect the sender.

Just right-click on the toolbar at the bottom right corner of the desktop, then click “Restart”.

Novastar NovaLCT reconnect or restart serve

As you can see from the above image, you can also click the “Detect Config” to open a window where you can set the configuration of sender card detect.

The following image is the pop-up window for your review.

Novastar NovaLCT detect config setting
As you can see. the default detection interval is 30 seconds. Setting a reasonable detection interval can help NovaLCT detect the sender card quickly. The interval should not be too long or too short.

Now, if everything is working correctly, let’s move on to the next section.

Know Loading Capacity & Cabinet Resolution

Please note that this section is specifically for beginners. If you are an expert in this field, feel free to skip to the next section to  start the screen configuration.

Loading Capacity?

You’ve probably heard the term as you navigate the world of LED screen.

  • The loading capacity determines how many cabinets you can connect to one output port and how many controllers you need for the project.
  • It is based on the total number of pixels, not the pixel pitch or the physical size of the screen.

Cabinet Resolution

Cabinet Resolution refers to the pixel resolution of a cabinet. The higher the resolution, the more LEDs the cabinet contains. Let’s break down how to calculate it:

Here we use 500mm×500mm P3.91 Cabinet as an example.

Example Cabinet:

  • Cabinet Dimension: 500mm x 500mm
  • Pixel Pitch: 3.91mm

Calculating Cabinet Pixel Resolution:

  1. Pixel Width = Cabinet Width / Pixel Pitch
  2. Pixel Height = Cabinet Height / Pixel Pitch
  3. Pixel Resolution = Pixel Width * Pixel Height

Using the given values:

  • Pixel Width = 500mm / 3.91mm ≈ 128 pixels
  • Pixel Height = 500mm / 3.91mm ≈ 128 pixels
  • Cabinet Pixel Resolution = 128 * 128 pixels

Calculate the Cabinets Quantity

After understanding how to calculate the pixel resolution, let’s determine how many cabinets can be loaded by one output port.

Here we use Novastar MCTRL300 sender example, the following is the key parameters it offers: 

  • Loading Capacity of Each Output: 650,000 pixels
  • Number of Outputs: 2
  • Total Pixel Loading Capacity: 1.3 million pixels (650,000 pixels/output * 2 outputs)

We still use P3.91 500*500mm cabinet to show. Here is a simple and quick formual:

  1. Cabinet Resolution = 128 pixels (width) * 128 pixels (height) = 16,384 pixels per cabinet
  2. Cabinet Number = Port Capacity / Cabinet Resolution
Using the given values:
  • Cabinet Number = 650,000 pixels / 16,384 pixels ≈ 39.68

Since we can’t have a fraction of a cabinet, we round down to the nearest whole number:

  • Cabinet Number = 39 cabinets

So, one output port can support approximately 39 cabinets with the given dimensions and pixel pitch.

Now, let’s move on to the screen configuration. The first step is Graphics Card Settings.

Graphics Card Settings

Before we proceed with the software operation, it’s crucial to configure certain settings on your graphics card to ensure optimal performance and display accuracy.

Set Display Mode

Windows provides four display modes: PC screen only, Duplicate, Extend, and Second screen only. You can access these options by pressing “Windows + P,” which will bring up a sidebar with the four choices. So, which one should you choose?

Our recommendation is “Duplicate“.

Following is our main reasons:

  1. Duplicate mode mirrors your primary screen to the secondary display, making it easier to identify and manage screen content during the configuration process.
  2. If any issues arise, having the same content on both screens allows for easier troubleshooting and adjustments.
  3. Ensures that what you see on your primary display is exactly what will appear on the secondary screen.
Windows computer Duplicate mode

Set Scale & Layout

Another important aspect is the scale and layout setting. For the best image display effect, it’s crucial to achieve a pixel-by-pixel representation without any scaling or stretching. 

To do this, right-click on the desktop and select “Display settings.” Then, in the Scale and layout section, set the scaling to 100%

100% scaling can ensure that everything is displayed at its native resolution, providing the clearest and most accurate image quality.

Set windows Scale & Layout for Novalct screen configuration

Now that all the graphics card settings are complete, let’s move on to the next part: configuring the NovaLCT software.

User Login

Before configuring the sending card settings, you are required to log in to the NovaLCT software.

In the Novalct window, click on the User(U) icon of the menu bar。

Novastar Novalct User login

There will be three menu items: 

  1. advanced synchronous system UserLogin”: Used for the synchronous control system.
  2. Enter Demonstration Mode“: Utilized for understanding the functions and parameters when the NovaLCT is not connected to the screen.
  3. Media Player Login“: Used for the asynchronous control system.

Here we select “advanced synchronous system user login” from the drop-down list.

Novastar Novalct advanced synchronous system user login

If you are required to input a password to continue, Please use “admin“.

After you have entered the correct password, the main window will be changed to like this:

NovaLCT main window after user loged in

The new window has added an additional icon called “Screen Configuration” in the toolbar, which is not present when not logged in.

Configure a Screen Manually

Set Input Source

Next, Click the “Screen Configuration” icon to proceed to the next step. You can also navigate to Settings > Screen Configuration from the menu bar.

After doing that, a dialog box will be shown as follows:

Choose a communication port of NovaLCT screen configuration

It appears to options to choose a communication port and three radio buttons: Configure Screen, Cloud Restore, and Local Restore

In this case, since we only have one sender, there’s no need to choose a port. So keep it default.

The other two options, “cloud restore” and “local restore,” are used for loading configuration files. We will discuss this in detail in another section.

Now, click on the Next button to continue the Screen Configuration.

After that, the Screen Configuration Window will be displayed as follows:

Configure Paramenter for Sending Card

As shown in the image above, this window contains three tabs: “Sending Card” “Receiving Card” and “Screen Connection“. To begin, we will navigate to the “Sending Card” tab first.

Please note that the layout and options on the screen configuration page may differ based on the sending and receiving card capabilities.

Afte you opened the sending card page, just proceed with the following steps:

  1. Choose the video source. HDMI, DVI, etc
  2. Set the resolution to match the graphic card output resolution.
  3. Set the refresh rate to match the input video source.
  4. Set bit depth of input source. Recommended input source bit depth is 8-bit.
  5. Click the Set button.

 It can ensure the screen displays pixel by pixel with the input source.

Input Source Configuration Of NovaLCT

In addition to manually setting the input source, NovaLCT offers an automatic configuration feature.

You can click the “Automatic Selection” button to achieve this. Novalct will select the input source based on the input signal. 

Then, Click “Send” to transmit the configuration information to the hardware.

NovaLCT Automatic Selection Input Source Configuration

When you have set the input source,  the next step is to click the “Refresh” button located in the Display Mode Area.

Then the display mode section will display the current display mode including sending card resolution, graphics output resolution, and current input source.

If the settings are correct, the sending card resolution will match the graphic card output resolution. Otherwise, please go back to the previous step to check where the settings might be incorrect.

The following screenshot is for your reference.

NovaLCT refresh current display mode

If everything is right, don’t forget to click the Save button to store configuration information on the hardware.

Novalct save the sending card setting of Screen configuration

In the meantime, if you want to clear all settings and reconfigure them, click the “Restore Factory Setting“, it will delete all screen configuration information and reset to the default value.

Please be cautious as this action is irreversible.

If you have verified all settings are correct, switch to the “Receiver Card” tab page to proceed to the next step.

Receiving Card Setting

In this step, we will set the receiving card parameters. Here is the main windows as following:

Novalct receiver card setting

As you can see, various parameters are distributed across three sections: Module Information, Cabinet Information, and Performance Settings.

  • Module Information: display the module’s basic parameters such as chip, size, scanning type, direction, and data groups.
  • Cabinet Information: Set the regular or irregular type cabinet parameters such as width, height, and module cascading direction.
  • Performance Setting: Set the refresh rate, grayscale level, etc.

Don’t worry; you only need a basic understanding of these information.

Loading from a RCFG/RCFGX File

So what to do now to get my screen to display properly?

Do you remember? When you purchase the modules from your suppliers, they usually send you a file with an RCFG or RCFGX extension via email, WhatsApp, or other similar tools. We usually call them RCG or RCFGX files.

The easiest and fastest way is to load the parameters from these types of files. 

You can easily achieve this by clicking “Load from File” and selecting a configuration file from your local computer.

Novalct loading file for receiver card setting

Once you’ve selected the file, be sure to click “Send to Receiver” to trigger a pop-up window that allows you to choose the receiver cards to be sent.

Novalct sending parameters to receiver card

You can choose “All Receiving Card ” or Specify Receiving Card.

Don’t know which one to choose?

If the screen is being configured for the first time, choose “All Receiving Card” which will send the configuration information to all receiving cards.  

Then click “Send.” If the connection is normal, an information window will appear with the message “Sent parameters successfully.” Click “OK” to close the window. Make sure to save the settings by clicking the “Save” button.

Novalct sending parameters to all receiver card

If the screen has been configured previously and you are only replacing some new receiver cards, pick “Specify Receiving Card“. This will ensure that only the specified have their parameters updated, while the others remain unchanged.

You can choose any card either by topology or by physical address. Similarly, click “Send,” then click “Save.”

Novalct Specify receiver cards to be sent parameters

Read Back Without a RCG RCFGX File

Sometimes, it’s okay if you don’t have the RCG/RCFG file. 

How to do it?

Just view the LED display. If the LED display is functioning properly, it indicates that the receiving card already contains the correct parameters. Simply read back these parameters and save them locally. 

This file will be named an RCG/RCFGX file too. It contains all the same information as the one provided by the supplier. 

You can click the Read from Receiving Card on the Receiving Card Tab page.

Novalct read back from the receiving card

A pop-up window will appear, allowing you to select which card to read back. Simply input the receiving card position by entering the Sending Card Number, Port Number, and Receiving Card Number. Then, click the “OK” button to proceed with the read-back process.

If the process completes successfully, the Receiving Card main window will update with the new parameters. Additionally, a message stating “Reading information from receiving card successfully” will be displayed.

Novalct read back information from the receiving card successfully

After that, make sure to click the “Save to File” button to save the parameters to a file. You can name the file as you prefer. This will allow you to load the file for the new receiver card in the future.

Connecting the Screen

After configuring the receiving card, each cabinet will show the same image. It will appear as the following image.

You may notice that only the top left portion of your computer desktop is displayed on the screen. This occurs because the screen cabinets need to be properly connected. 

Currently, each cabinet doesn’t know which part of the video source it should display. Therefore, we need to instruct them on how to display the content and make them function as a unified whole. So the screen connection is also called a cabinet connection.

Just switch to the Screen Connection tab page to start the connectin setting.

Step 1: Enable Mapping

Before we go to the next step.  Bu sure to enable the mapping function first.

What is the mapping function, and why enable it? 

Screen configuration is a complex task, especially when you don’t know the physical positions of receiving cards within each cabinet. This can lead to confusion and errors , making it time-consuming and prone to mistakes.

The mapping function can help you to avoid this problem. It can display a number on each cabinet when enabled. This number represents the physical position of the receiving card. Specifically:

  • “P” indicates the output port.
  • “#” indicates the number of the receiving card.

By enabling mapping, you can easily follow the displayed numbers to connect the screens. This makes the process quick and straightforward.

Here are a few steps you can take to enable it.

  1. Locate the Enable Mapping Button:
    • Find the “Enable Mapping” button at the bottom of the Windows interface.
  2. Enable Mapping:
    • Click the “Enable Mapping” button. The software will automatically enable the mapping function.
  3. Verify Mapping:
    • Once enabled, the button will change to “Close Mapping.” This indicates that the mapping function is active, and each cabinet will display its respective numbers.
  4. Disable Mapping (if needed):
    • You can disable the mapping function at any time by clicking the “Close Mapping” button.

You can check the following picture if you don’t know where is the button.

Novalct enable mapping function

Here’s an example of the mapping function being enabled.

Step 2: Choose the quantity of the screen. 

To determine the quantity of the screen , follow these guidelines:

  1. Single Screen Configuration:
    • If the multiple output ports of the sending card are used to load different areas of the same screen, set the screen quantity to 1. This means all the output ports are contributing to a single, unified display.
  2. Multiple Screen Configuration:
    • If the multiple output ports of the sending card are used to load different screens, set the screen quantity to the total number of screens being loaded. For example, if you have three separate screens and each output port is dedicated to a different screen, set the screen quantity to 3.

Here is an example of single quantity screen:

Novalct multiple output ports to load different areas of the same screen

Here is an example of multiple quantity screen:

Here, for simplicity, we start by selecting one screen. The process for configuring more than one screen is the same as for a single screen.

Step 3: After setting the quantity, next is to set the column and row quantity of receiving cards. On the Standard Screen page, enter the value of column and row quantities. 

In our example, I set it to 6 columns and 4 rows. Then, click the “Reset All” button, and the window will change to a 6×4 matrix, as shown in the following figure. This information enables the software to calculate the total screen resolution.

Novalct set the column and row quantity of receiving cards

Step 4: Select the sending card number and the output port. 

NovaLCT is a smart software, so when we have connected it with the sending card, it can recognize the main information including the quantity it connected. 

Here, we can select the corresponding sending card number and Ethernet Port No by clicking the button labeled with numbers 1, 2, 3, 4, 5, 6, etc, 

Step 5: Specify the resolution of the receiving card.

Just enter the width and height resolution (Pixel Loading Capacity). If you’re unsure of the values, you can find them by clicking on the “Receiving Card” tab window.  For example. Here we set the width to 64 pixels, and height to 32 pixels.

After setting the resolution (Red Area 1), be sure to use the mouse left-click the table cell (Red Area 2on the right of the window (Red Area 3), which stands for the LED display cabinet layout. Typically, one cabinet corresponds to one receiving card.

If you’re unsure about the red areas I mentioned, please refer to the following image.

Novalct Apply the resolution to selected receiving card

After clicked the cell, you can see that the background have been change to another color, and the text have been changed to the following:

  • Sending Card: 1
  • Port 1
  • Receiving Card :1
  • Width: 64
  • Height: 32

It means that you have specified the receiving card resolution of the cabinet (column 1 and row 1) as 64 pixels width 32 pixels height,  the receiving card number as 1, and the cabinet is connected to the output port 1 of sending card number 1 logically.

Simply repeat this step for the left cabinet.

However, if you have a large number of receiving cards, this can be a very time-consuming task. But don’t worry, batch operations can help you complete it quickly.

Here are three simple batch execution functions located the Red Area 1:

  1. Apply to Entire Column: Set the loading capacity width of the selected receiving card to all receiving cards in the same column.
  2. Apply to Entire Row: Copy the loading capacity height of the selected receiving card to all receiving cards in the same row.
  3. Apply to the Current Port: Specify the current loading capacity width and height for all receiving cards connected to the current output port.

And more, if something is wrong, you can click the “Reset All” button to reset.

So, don’t be afraid to try each function.

Set the Receiving Card Connection

Up to this point, all receiving cards are logically isolated; they are unaware of their signal sources and destinations. We need to establish connections between them now. Sometimes we call this operation “Route Cable” or a Chinese word: 走线.

Let us return to the LED display layout area (Red Area 3). 

Click the Source Receiving Card (which is the first one linked to the sending card, labeled with an “S” for source) and then drag the left mouse button to the next receiving card, and then to the next one, and so on, until you reach the last receiving card (labeled with an “E” for end).

After that, you will see a green route with red arrows, matching the direction of your mouse movement during the click-drag operation you just performed.

After that, The first receiving card (the start of the route) will be labeled with an “S” for the source, and the last receiving card (the end of the route) will be labeled with an “E” for the end.

In addition, you can use Quick Connection to accomplish this. It offers several common route templates to help you set up the connection. Just navigate to the left of the window to select the desired template, then left-click the screen layout are drag.

Like the picture above, I use the first template, and the right window displays a similar route graphic.

In the meantime, there are some useful tips to help you complete the screen connection:

  1. Right-click to cancel the connection operation.
  2. Use the Zoom arrow 1 to adjust the receiving card interface in the middle. 
  3. Click the return button 2 to go back to the previous step.
  4. Use the clear button 3 to remove all connections.
  5. Click the star button 4 to mark a receiving card.
  6. Check “Hide Mapping Line”  5 to conceal the receiving card mapping line.

Now, we have done the screen connection for one output port of the sending card, if you have other ports, just repeat the above steps.

Novalct multiple output ports screen connection

The image above is an example of a screen connection using two output ports.  The green line is loaded by output port 1, and the yellow line is loaded by output port 2.

Send to the Hardware

After completing all screen connections for all ports, make sure to click the “Send to HW” button. This action sends the configuration information to the hardware for storage, ensuring that the hardware operates as desired.

Make sure to click the “Save” button to store the configuration information for the hardware.

Novalct screen connection save to Hardware

Additionally, you can click “Read from HW” to retrieve the saved information. It will help you quickly understand the screen connection if you forget it next time. Besides, it saves time if you want to configure the screen again.

Save to a Backup File

This step is not mandatory, but we highly recommend you do this.

 Sometimes the screen needs hardware replacements, such as the sending card or receiving card. Without a local file where the connection information is stored, you’d have to reconfigure everything, which can be quite tedious, wouldn’t you agree?

However, if you have this type of file, you can simply click the “Load the file” button, and the software will automatically load the information into the interface. No need to reconfigure. Just a few clicks, and you can enjoy a coffee break instead of sitting in front of the computer.

So, how to do this?

Click the “Save to File” button, as shown in the following figure. This will save the configuration as a screen file with the “.scr” suffix.

Save Configuration Files

This step is optional too.

First, click the “Save System Configuration File” button (indicated by the red box at the bottom of the window). Then, it will trigger a pop-up window as follows:

Novalct save configuratin file to cloud and local computer

If you have a VNNOX Care account and want to save the configuration files to the cloud, follow these steps:

  1. Enter all the required information:
    • VNNOX Care User Name: Your VNNOX account name
    • Password: Your VNNOX account password
    • Screen Name: Any name you choose
    • System Configuration Name: Any name you choose
    • Select a server node. Europe, China, American, Australia, AWS.
  2. Click the “Save” button. If everything is set up correctly, the Novastar Cloud will automatically register the screen using the provided screen name. Additionally, VNNOX will save all the screen information into three main files:
    • .rcfgx file: The receiving card configuration file
    • .scr file: The screen connection file
    • .cfg file: The version file, which includes the NovaLCT version number and the receiving card program package

If you do not have a VNNOX Care account or you just want to save the configuration files to the local, then you do not need to input anything. Just select the file folder and enter the file name you want it to be. 

After that, a .scfg file will be saved on the local computer.  Please noted. this way don’t contain the .rcfgx, .scr, and .cfg file.

Test Connection

Once all steps are completed, we need to test the connection status. By using the “Detect Communication Status” feature, we can check the status of all receiving cards. 

First, click the “Detect Communication Status” button. You can the following image which is labeled as number 1.

A pop-up window will appear, asking you to select the screen you wish to detect. Choose the desired screen and click “OK.” Here we select Screen1.

Soon the status of all receiving cards that are connected the screen (Here it is Screen1) will be displayed in front of you with either a red or green background.

  • Green: Communication is normal.
  • Red: Communication is abnormal, requiring a check of the cable connections.
Novalct detect communication status result

If all statuses are green, congratulations! All screen configurations have been completed. And, when we check the image. it will display as a complete one. Each cabinet knows which part it will show.

Novalct display as a complete image

Connect the NovaLCT to the Sending Card

If the previous step went smoothly, NovaLCT will automatically detect the sending card. It will display the status and various parameters of the sender card in the main window. These parameters include port information, SN, device name, etc.

This process requires no additional actions from us. If the main window does not show any information about the sending card, it means you need to recheck the connection or device.

You can check the FAQ section at the end of this guide to see if there is any information related to your error.

In addition, if there is still no signal  or no status update in the main window, you can try to restart the server or reconnect the sender.

Just right-click on the toolbar at the bottom right corner of the desktop, then click “Restart”.

Novastar NovaLCT reconnect or restart serve

As you can see from the above image, you can also click the “Detect Config” to open a window where you can set the configuration of sender card detect.

The following image is the pop-up window for your review.

Novastar NovaLCT detect config setting
As you can see. the default detection interval is 30 seconds. Setting a reasonable detection interval can help NovaLCT detect the sender card quickly. The interval should not be too long or too short.

Now, if everything is working correctly, let’s move on to the next section.

Know Loading Capacity & Cabinet Resolution

Please note that this section is specifically for beginners. If you are an expert in this field, feel free to skip to the next section to  start the screen configuration.

Loading Capacity?

You’ve probably heard the term as you navigate the world of LED screen.

  • The loading capacity determines how many cabinets you can connect to one output port and how many controllers you need for the project.
  • It is based on the total number of pixels, not the pixel pitch or the physical size of the screen.

Cabinet Resolution

Cabinet Resolution refers to the pixel resolution of a cabinet. The higher the resolution, the more LEDs the cabinet contains. Let’s break down how to calculate it:

Here we use 500mm×500mm P3.91 Cabinet as an example.

Example Cabinet:

  • Cabinet Dimension: 500mm x 500mm
  • Pixel Pitch: 3.91mm

Calculating Cabinet Pixel Resolution:

  1. Pixel Width = Cabinet Width / Pixel Pitch
  2. Pixel Height = Cabinet Height / Pixel Pitch
  3. Pixel Resolution = Pixel Width * Pixel Height

Using the given values:

  • Pixel Width = 500mm / 3.91mm ≈ 128 pixels
  • Pixel Height = 500mm / 3.91mm ≈ 128 pixels
  • Cabinet Pixel Resolution = 128 * 128 pixels

Calculate the Cabinets Quantity

After understanding how to calculate the pixel resolution, let’s determine how many cabinets can be loaded by one output port.

Here we use Novastar MCTRL300 sender example, the following is the key parameters it offers: 

  • Loading Capacity of Each Output: 650,000 pixels
  • Number of Outputs: 2
  • Total Pixel Loading Capacity: 1.3 million pixels (650,000 pixels/output * 2 outputs)

We still use P3.91 500*500mm cabinet to show. Here is a simple and quick formual:

  1. Cabinet Resolution = 128 pixels (width) * 128 pixels (height) = 16,384 pixels per cabinet
  2. Cabinet Number = Port Capacity / Cabinet Resolution
Using the given values:
  • Cabinet Number = 650,000 pixels / 16,384 pixels ≈ 39.68

Since we can’t have a fraction of a cabinet, we round down to the nearest whole number:

  • Cabinet Number = 39 cabinets

So, one output port can support approximately 39 cabinets with the given dimensions and pixel pitch.

Now, let’s move on to the screen configuration. The first step is Graphics Card Settings.

Graphics Card Settings

Before we proceed with the software operation, it’s crucial to configure certain settings on your graphics card to ensure optimal performance and display accuracy.

Set Display Mode

Windows provides four display modes: PC screen only, Duplicate, Extend, and Second screen only. You can access these options by pressing “Windows + P,” which will bring up a sidebar with the four choices. So, which one should you choose?

Our recommendation is “Duplicate“.

Following is our main reasons:

  1. Duplicate mode mirrors your primary screen to the secondary display, making it easier to identify and manage screen content during the configuration process.
  2. If any issues arise, having the same content on both screens allows for easier troubleshooting and adjustments.
  3. Ensures that what you see on your primary display is exactly what will appear on the secondary screen.
Windows computer Duplicate mode

Set Scale & Layout

Another important aspect is the scale and layout setting. For the best image display effect, it’s crucial to achieve a pixel-by-pixel representation without any scaling or stretching. 

To do this, right-click on the desktop and select “Display settings.” Then, in the Scale and layout section, set the scaling to 100%

100% scaling can ensure that everything is displayed at its native resolution, providing the clearest and most accurate image quality.

Set windows Scale & Layout for Novalct screen configuration

Now that all the graphics card settings are complete, let’s move on to the next part: configuring the NovaLCT software.

User Login

Before configuring the sending card settings, you are required to log in to the NovaLCT software.

In the Novalct window, click on the User(U) icon of the menu bar。

Novastar Novalct User login

There will be three menu items: 

  1. advanced synchronous system UserLogin”: Used for the synchronous control system.
  2. Enter Demonstration Mode“: Utilized for understanding the functions and parameters when the NovaLCT is not connected to the screen.
  3. Media Player Login“: Used for the asynchronous control system.

Here we select “advanced synchronous system user login” from the drop-down list.

Novastar Novalct advanced synchronous system user login

If you are required to input a password to continue, Please use “admin“.

After you have entered the correct password, the main window will be changed to like this:

NovaLCT main window after user loged in

The new window has added an additional icon called “Screen Configuration” in the toolbar, which is not present when not logged in.

Configure a Screen Manually

Set Input Source

Next, Click the “Screen Configuration” icon to proceed to the next step. You can also navigate to Settings > Screen Configuration from the menu bar.

After doing that, a dialog box will be shown as follows:

Choose a communication port of NovaLCT screen configuration

It appears to options to choose a communication port and three radio buttons: Configure Screen, Cloud Restore, and Local Restore

In this case, since we only have one sender, there’s no need to choose a port. So keep it default.

The other two options, “cloud restore” and “local restore,” are used for loading configuration files. We will discuss this in detail in another section.

Now, click on the Next button to continue the Screen Configuration.

After that, the Screen Configuration Window will be displayed as follows:

Configure Paramenter for Sending Card

As shown in the image above, this window contains three tabs: “Sending Card” “Receiving Card” and “Screen Connection“. To begin, we will navigate to the “Sending Card” tab first.

Please note that the layout and options on the screen configuration page may differ based on the sending and receiving card capabilities.

Afte you opened the sending card page, just proceed with the following steps:

  1. Choose the video source. HDMI, DVI, etc
  2. Set the resolution to match the graphic card output resolution.
  3. Set the refresh rate to match the input video source.
  4. Set bit depth of input source. Recommended input source bit depth is 8-bit.
  5. Click the Set button.

 It can ensure the screen displays pixel by pixel with the input source.

Input Source Configuration Of NovaLCT

In addition to manually setting the input source, NovaLCT offers an automatic configuration feature.

You can click the “Automatic Selection” button to achieve this. Novalct will select the input source based on the input signal. 

Then, Click “Send” to transmit the configuration information to the hardware.

NovaLCT Automatic Selection Input Source Configuration

When you have set the input source,  the next step is to click the “Refresh” button located in the Display Mode Area.

Then the display mode section will display the current display mode including sending card resolution, graphics output resolution, and current input source.

If the settings are correct, the sending card resolution will match the graphic card output resolution. Otherwise, please go back to the previous step to check where the settings might be incorrect.

The following screenshot is for your reference.

NovaLCT refresh current display mode

If everything is right, don’t forget to click the Save button to store configuration information on the hardware.

Novalct save the sending card setting of Screen configuration

In the meantime, if you want to clear all settings and reconfigure them, click the “Restore Factory Setting“, it will delete all screen configuration information and reset to the default value.

Please be cautious as this action is irreversible.

If you have verified all settings are correct, switch to the “Receiver Card” tab page to proceed to the next step.

Receiving Card Setting

In this step, we will set the receiving card parameters. Here is the main windows as following:

Novalct receiver card setting

As you can see, various parameters are distributed across three sections: Module Information, Cabinet Information, and Performance Settings.

  • Module Information: display the module’s basic parameters such as chip, size, scanning type, direction, and data groups.
  • Cabinet Information: Set the regular or irregular type cabinet parameters such as width, height, and module cascading direction.
  • Performance Setting: Set the refresh rate, grayscale level, etc.

Don’t worry; you only need a basic understanding of these information.

Loading from a RCFG/RCFGX File

So what to do now to get my screen to display properly?

Do you remember? When you purchase the modules from your suppliers, they usually send you a file with an RCFG or RCFGX extension via email, WhatsApp, or other similar tools. We usually call them RCG or RCFGX files.

The easiest and fastest way is to load the parameters from these types of files. 

You can easily achieve this by clicking “Load from File” and selecting a configuration file from your local computer.

Novalct loading file for receiver card setting

Once you’ve selected the file, be sure to click “Send to Receiver” to trigger a pop-up window that allows you to choose the receiver cards to be sent.

Novalct sending parameters to receiver card

You can choose “All Receiving Card ” or Specify Receiving Card.

Don’t know which one to choose?

If the screen is being configured for the first time, choose “All Receiving Card” which will send the configuration information to all receiving cards.  

Then click “Send.” If the connection is normal, an information window will appear with the message “Sent parameters successfully.” Click “OK” to close the window. Make sure to save the settings by clicking the “Save” button.

Novalct sending parameters to all receiver card

If the screen has been configured previously and you are only replacing some new receiver cards, pick “Specify Receiving Card“. This will ensure that only the specified have their parameters updated, while the others remain unchanged.

You can choose any card either by topology or by physical address. Similarly, click “Send,” then click “Save.”

Novalct Specify receiver cards to be sent parameters

Read Back Without a RCG RCFGX File

Sometimes, it’s okay if you don’t have the RCG/RCFG file. 

How to do it?

Just view the LED display. If the LED display is functioning properly, it indicates that the receiving card already contains the correct parameters. Simply read back these parameters and save them locally. 

This file will be named an RCG/RCFGX file too. It contains all the same information as the one provided by the supplier. 

You can click the Read from Receiving Card on the Receiving Card Tab page.

Novalct read back from the receiving card

A pop-up window will appear, allowing you to select which card to read back. Simply input the receiving card position by entering the Sending Card Number, Port Number, and Receiving Card Number. Then, click the “OK” button to proceed with the read-back process.

If the process completes successfully, the Receiving Card main window will update with the new parameters. Additionally, a message stating “Reading information from receiving card successfully” will be displayed.

Novalct read back information from the receiving card successfully

After that, make sure to click the “Save to File” button to save the parameters to a file. You can name the file as you prefer. This will allow you to load the file for the new receiver card in the future.

Connecting the Screen

After configuring the receiving card, each cabinet will show the same image. It will appear as the following image.

You may notice that only the top left portion of your computer desktop is displayed on the screen. This occurs because the screen cabinets need to be properly connected. 

Currently, each cabinet doesn’t know which part of the video source it should display. Therefore, we need to instruct them on how to display the content and make them function as a unified whole. So the screen connection is also called a cabinet connection.

Just switch to the Screen Connection tab page to start the connectin setting.

Step 1: Enable Mapping

Before we go to the next step.  Bu sure to enable the mapping function first.

What is the mapping function, and why enable it? 

Screen configuration is a complex task, especially when you don’t know the physical positions of receiving cards within each cabinet. This can lead to confusion and errors , making it time-consuming and prone to mistakes.

The mapping function can help you to avoid this problem. It can display a number on each cabinet when enabled. This number represents the physical position of the receiving card. Specifically:

  • “P” indicates the output port.
  • “#” indicates the number of the receiving card.

By enabling mapping, you can easily follow the displayed numbers to connect the screens. This makes the process quick and straightforward.

Here are a few steps you can take to enable it.

  1. Locate the Enable Mapping Button:
    • Find the “Enable Mapping” button at the bottom of the Windows interface.
  2. Enable Mapping:
    • Click the “Enable Mapping” button. The software will automatically enable the mapping function.
  3. Verify Mapping:
    • Once enabled, the button will change to “Close Mapping.” This indicates that the mapping function is active, and each cabinet will display its respective numbers.
  4. Disable Mapping (if needed):
    • You can disable the mapping function at any time by clicking the “Close Mapping” button.

You can check the following picture if you don’t know where is the button.

Novalct enable mapping function

Here’s an example of the mapping function being enabled.

Step 2: Choose the quantity of the screen. 

To determine the quantity of the screen , follow these guidelines:

  1. Single Screen Configuration:
    • If the multiple output ports of the sending card are used to load different areas of the same screen, set the screen quantity to 1. This means all the output ports are contributing to a single, unified display.
  2. Multiple Screen Configuration:
    • If the multiple output ports of the sending card are used to load different screens, set the screen quantity to the total number of screens being loaded. For example, if you have three separate screens and each output port is dedicated to a different screen, set the screen quantity to 3.

Here is an example of single quantity screen:

Novalct multiple output ports to load different areas of the same screen

Here is an example of multiple quantity screen:

Here, for simplicity, we start by selecting one screen. The process for configuring more than one screen is the same as for a single screen.

Step 3: After setting the quantity, next is to set the column and row quantity of receiving cards. On the Standard Screen page, enter the value of column and row quantities. 

In our example, I set it to 6 columns and 4 rows. Then, click the “Reset All” button, and the window will change to a 6×4 matrix, as shown in the following figure. This information enables the software to calculate the total screen resolution.

Novalct set the column and row quantity of receiving cards

Step 4: Select the sending card number and the output port. 

NovaLCT is a smart software, so when we have connected it with the sending card, it can recognize the main information including the quantity it connected. 

Here, we can select the corresponding sending card number and Ethernet Port No by clicking the button labeled with numbers 1, 2, 3, 4, 5, 6, etc, 

Step 5: Specify the resolution of the receiving card.

Just enter the width and height resolution (Pixel Loading Capacity). If you’re unsure of the values, you can find them by clicking on the “Receiving Card” tab window.  For example. Here we set the width to 64 pixels, and height to 32 pixels.

After setting the resolution (Red Area 1), be sure to use the mouse left-click the table cell (Red Area 2on the right of the window (Red Area 3), which stands for the LED display cabinet layout. Typically, one cabinet corresponds to one receiving card.

If you’re unsure about the red areas I mentioned, please refer to the following image.

Novalct Apply the resolution to selected receiving card

After clicked the cell, you can see that the background have been change to another color, and the text have been changed to the following:

  • Sending Card: 1
  • Port 1
  • Receiving Card :1
  • Width: 64
  • Height: 32

It means that you have specified the receiving card resolution of the cabinet (column 1 and row 1) as 64 pixels width 32 pixels height,  the receiving card number as 1, and the cabinet is connected to the output port 1 of sending card number 1 logically.

Simply repeat this step for the left cabinet.

However, if you have a large number of receiving cards, this can be a very time-consuming task. But don’t worry, batch operations can help you complete it quickly.

Here are three simple batch execution functions located the Red Area 1:

  1. Apply to Entire Column: Set the loading capacity width of the selected receiving card to all receiving cards in the same column.
  2. Apply to Entire Row: Copy the loading capacity height of the selected receiving card to all receiving cards in the same row.
  3. Apply to the Current Port: Specify the current loading capacity width and height for all receiving cards connected to the current output port.

And more, if something is wrong, you can click the “Reset All” button to reset.

So, don’t be afraid to try each function.

Set the Receiving Card Connection

Up to this point, all receiving cards are logically isolated; they are unaware of their signal sources and destinations. We need to establish connections between them now. Sometimes we call this operation “Route Cable” or a Chinese word: 走线.

Let us return to the LED display layout area (Red Area 3). 

Click the Source Receiving Card (which is the first one linked to the sending card, labeled with an “S” for source) and then drag the left mouse button to the next receiving card, and then to the next one, and so on, until you reach the last receiving card (labeled with an “E” for end).

After that, you will see a green route with red arrows, matching the direction of your mouse movement during the click-drag operation you just performed.

After that, The first receiving card (the start of the route) will be labeled with an “S” for the source, and the last receiving card (the end of the route) will be labeled with an “E” for the end.

In addition, you can use Quick Connection to accomplish this. It offers several common route templates to help you set up the connection. Just navigate to the left of the window to select the desired template, then left-click the screen layout are drag.

Like the picture above, I use the first template, and the right window displays a similar route graphic.

In the meantime, there are some useful tips to help you complete the screen connection:

  1. Right-click to cancel the connection operation.
  2. Use the Zoom arrow 1 to adjust the receiving card interface in the middle. 
  3. Click the return button 2 to go back to the previous step.
  4. Use the clear button 3 to remove all connections.
  5. Click the star button 4 to mark a receiving card.
  6. Check “Hide Mapping Line”  5 to conceal the receiving card mapping line.

Now, we have done the screen connection for one output port of the sending card, if you have other ports, just repeat the above steps.

Novalct multiple output ports screen connection

The image above is an example of a screen connection using two output ports.  The green line is loaded by output port 1, and the yellow line is loaded by output port 2.

Send to the Hardware

After completing all screen connections for all ports, make sure to click the “Send to HW” button. This action sends the configuration information to the hardware for storage, ensuring that the hardware operates as desired.

Make sure to click the “Save” button to store the configuration information for the hardware.

Novalct screen connection save to Hardware

Additionally, you can click “Read from HW” to retrieve the saved information. It will help you quickly understand the screen connection if you forget it next time. Besides, it saves time if you want to configure the screen again.

Save to a Backup File

This step is not mandatory, but we highly recommend you do this.

 Sometimes the screen needs hardware replacements, such as the sending card or receiving card. Without a local file where the connection information is stored, you’d have to reconfigure everything, which can be quite tedious, wouldn’t you agree?

However, if you have this type of file, you can simply click the “Load the file” button, and the software will automatically load the information into the interface. No need to reconfigure. Just a few clicks, and you can enjoy a coffee break instead of sitting in front of the computer.

So, how to do this?

Click the “Save to File” button, as shown in the following figure. This will save the configuration as a screen file with the “.scr” suffix.

Save Configuration Files

This step is optional too.

First, click the “Save System Configuration File” button (indicated by the red box at the bottom of the window). Then, it will trigger a pop-up window as follows:

Novalct save configuratin file to cloud and local computer

If you have a VNNOX Care account and want to save the configuration files to the cloud, follow these steps:

  1. Enter all the required information:
    • VNNOX Care User Name: Your VNNOX account name
    • Password: Your VNNOX account password
    • Screen Name: Any name you choose
    • System Configuration Name: Any name you choose
    • Select a server node. Europe, China, American, Australia, AWS.
  2. Click the “Save” button. If everything is set up correctly, the Novastar Cloud will automatically register the screen using the provided screen name. Additionally, VNNOX will save all the screen information into three main files:
    • .rcfgx file: The receiving card configuration file
    • .scr file: The screen connection file
    • .cfg file: The version file, which includes the NovaLCT version number and the receiving card program package

If you do not have a VNNOX Care account or you just want to save the configuration files to the local, then you do not need to input anything. Just select the file folder and enter the file name you want it to be. 

After that, a .scfg file will be saved on the local computer.  Please noted. this way don’t contain the .rcfgx, .scr, and .cfg file.

Test Connection

Once all steps are completed, we need to test the connection status. By using the “Detect Communication Status” feature, we can check the status of all receiving cards. 

First, click the “Detect Communication Status” button. You can the following image which is labeled as number 1.

A pop-up window will appear, asking you to select the screen you wish to detect. Choose the desired screen and click “OK.” Here we select Screen1.

Soon the status of all receiving cards that are connected the screen (Here it is Screen1) will be displayed in front of you with either a red or green background.

  • Green: Communication is normal.
  • Red: Communication is abnormal, requiring a check of the cable connections.
Novalct detect communication status result

If all statuses are green, congratulations! All screen configurations have been completed. And, when we check the image. it will display as a complete one. Each cabinet knows which part it will show.
