Complete NovaLCT Screen Configuration and Download Guide (2026)

Configuring your LED screen via NovaLCT may feel overwhelming for new operators. However, you can finish configuring your LED displays within 20 minutes by following the right steps offered below.

This guide covers the full NovaLCT screen configuration steps, from computer connections, screen configuration, sending card settings, display testing, and hardware settings.

You can also locate the latest NovaLCT software (NovaLCT V5.9.2) download resources at the bottom of this article.

NovaLCT is NovaStar’s Windows tool for setting up compatible LED screens. Use it to configure receiving cards and arrange cabinets on the screen map.

The video source supplies the picture. NovaLCT tells the hardware how to display it.

Key features and functions include:

• Screen configuration: Set up sending cards and receiving-card parameters.
• Cabinet mapping: Arrange cabinets to match the physical cable connections.
• Brightness adjustment: Adjust screen brightness and supported color settings.
• Display calibration: Apply calibration data on compatible hardware.
• System monitoring: Check supported hardware status and communication errors.
• Configuration backup: Save and restore receiving-card settings and screen layouts.

Available functions depend on the connected hardware and firmware.

Read the full model numbers on the controller and receiving card. Check both against the supported hardware for your software release.

Keep suffixes such as Pro, Plus, and N in your notes. An MRV416-N label identifies the receiving card; record the controller model separately.

Choose the Windows version specified for your LED screen. For the latest NovaLCT V5.9.2, select the manual for your control system: live video or multimedia player.

On NovaStar’s official website, select Software, then find NovaLCT. Check the full version number before downloading.

Keep the installer with the project files so another technician can use the same version.

Extract the V5.9.2 package before running the installer. When NovaLCT opens, check that it shows NovaLCT V5.9.2.

Read the release notes before connecting a working screen, especially if you are replacing an older installation.

Use an older installer when you need to reproduce a working setup. Match the entire version number: V5.4.4.6 and V5.4.0 are different builds.

Note: You can go to our Novastar download page to get more files on various Novastar controllers.

For a live video input, use the Synchronous Control System manual. For a screen driven by a multimedia player, use the Multimedia Player manual.

The release notes explain what changed. A communication driver helps the PC detect hardware; receiving-card firmware runs on the card itself.

Important Notes: NovaLCT runs on Windows 7 and newer Windows operating systems only.

Install Nova LCT software on a supported 64-bit Windows PC. Check that it detects the powered controller before loading any cabinet settings.

The V5.9.2 manual lists 64-bit Windows 7, a fifth-generation Core i3, and 4 GB of RAM as minimums.

NovaStar recommends 64-bit Windows 10 or later, a tenth-generation Core i5 or better, and at least 8 GB of RAM. Test the intended USB or network connection before going onsite.

1. Download the selected release from a verified source and extract the archive into a local folder.
2. Run the installer using the permissions required by your organization and follow the setup prompts.
3. Install the appropriate communication driver when required by the package or controller documentation.
4. Open Novastar NovaLCT, check its version, connect one powered controller, and confirm detection before configuring the screen.

If the installer is blocked, have the package and alert checked before continuing. Record the driver version alongside the NovaLCT version.

Novastar NovaLCT has no native Mac installer in the download catalog. Use a supported Windows PC when your screen requires NovaLCT.

SmartLCT has a Mac edition for certain devices. Check your controller model before choosing it.

Save the receiving-card file and the screen connection file in a dated project folder. Keep the last working copy untouched.

Photograph the cable route as well. A photo helps you trace the wiring, but you need the configuration files to restore the screen.

Test the cabinet settings first, then map the screen. Once every cabinet shows the correct part of a numbered grid, save the settings to hardware.

These steps cover a synchronous controller and a regular cabinet layout. Mark the first cabinet on each output port before opening the screen map.

Connect the PC to the controller’s supported USB or network control port. Connect the video source to the controller’s video input.

The control cable does not carry the live picture. Trace the controller’s LED output cable to the first receiving card on each port.

Choose Duplicate to mirror the desktop, or Extend to send a separate desktop to the controller. In Extend mode, move the playback window onto that display.

Four 192 × 192-pixel cabinets across and three high make a 768 × 576-pixel wall. A 1920 × 1080 source fits only if the processor scales or positions it as needed.

Open User and choose the advanced synchronous login. The documented default password is admin; multimedia players use a separate device login.

Open Screen Configuration and select the port for your controller. If the device is missing, check the connection before sending settings.

Select the video input in use. Check that the controller detects the expected resolution and frame rate.

Check the load on each output port. A wall can fit the controller’s total capacity while one port exceeds its pixel or width limit.

Load the supplier’s RCFG or RCFGX file for the exact cabinet revision. Matching pixel pitch alone does not establish compatibility.

Test one cabinet before sending the file to the rest. If your receiving card requires an NCP file, follow its own setup procedure.

For an existing screen, follow the receiving-card configuration backup tutorial before changing the card settings.

Enter the width and height driven by each receiving card in pixels, not millimeters. Select an output port and map each cabinet in the order its data cable reaches it.

On a zigzag route, the second row runs in the opposite direction. Check whether your drawing shows the wall from the front or the rear.

Already have an SCR file? The screen-connection file tutorial below shows how to load it. An SCR file describes cabinet positions; the receiving-card file describes cabinet electronics.

Display a numbered grid and check the corners, row changes, and port boundaries. Every number should appear once, in its expected position.

Then test solid red, green, blue, and gray. If the wall will be filmed, check the image through the production camera as well.

Sending settings tests them; saving to hardware keeps them after restart. Once the picture is correct, use Save or Save to HW for the intended devices.

Export a dated backup. During the maintenance window, restart the controller and check the numbered grid again.

Choose the application your controller supports. Use NovaLCT for a project that requires NovaLCT; choose SmartLCT for visual layout only if it supports your hardware.

Choose the SmartLCT package for Windows or Mac. V3.5.14 is the newest release listed on NovaStar’s SmartLCT download page.

For V3.5.14, open the official page below and select Windows or Mac. Use an older package only when your project requires that version.

The SmartLCT V3.5.13 manual lists Windows 7 or later and macOS 10.10 or later. Check your actual release and computer before taking it onsite.

Use the table to compare platform support and setup tasks. Check file compatibility before switching tools on an existing project.

If NovaLCT cannot find the controller, check the PC connection. If it detects the controller but the cabinets appear out of order, check the screen map first.

Check controller power, the control port, and the USB cable or network adapter. Try a known-good cable before changing screen parameters.

If detection stopped after a driver update, compare the driver and software versions with the last working setup.

If a cabinet repeats another cabinet’s picture, check its map position and starting coordinates. If a whole row is reversed, trace the cable at the row change.

Check the physical route against the saved map before rebuilding the layout.

Check whether the fault affects one module, one cabinet, or the entire wall. Compare the receiving-card file and wiring with a known-good cabinet.

If flicker appears only on camera, check camera timing before changing the screen’s refresh settings. Test any adjustment on a small area first.

Use Save to HW where available, then restart during the maintenance window. If an old layout returns, check whether a startup preset is restoring it.
