NovaLCT Guide: Novastar Software Download, Setup & Basic Operation

Novastar software NovaLCT works with a wide range of NovaStar control hardware, covering both real-time and standalone systems. As long as your system uses official NovaStar sending cards, receiving cards, or multimedia players, NovaLCT can recognise and configure them.

Novastar software NovaLCT supports the MCTRL family (MCTRL300, MCTRL600, MCTRL660, MCTRL4K), the VX series of video processors (VX4S, VX6S, VX400 Pro, VX600 Pro, VX1000, VX2000 Pro), and advanced controllers such as the A8s and A9s. With these devices you can set screen resolution, map output ports to cabinets, adjust timing, and verify signal integrity before going live.

Asynchronous systems run pre-loaded content with no constant PC connection. Novastar software NovaLCT supports the TB6, TB7, TB8, TB30, TB40 and TB50 players, the SMP100 to SMP400 range, and the UHD Jr and UHD Pro. For these devices NovaLCT defines screen layout, schedules brightness changes, configures network settings, manages playlists remotely, and updates firmware over LAN or Wi-Fi.

Novastar software NovaLCT also works with the standard NovaStar receiving-card range, including the MRV328, MRV412, RV908 and DH7512-S. It detects each card’s position in the screen and applies calibration data through RCFG and RCFGX files. Some colour features depend on the card and module chip fitted — the Image Booster Engine supports colorimeter-based calibration, while 18bit+ and 22bit+ modes extend grayscale performance.

Novastar software NovaLCT runs on Windows, and NovaStar does not publish a native macOS or Linux build. Windows 7 is no longer supported, so use a native Windows 10 or 11 64-bit PC with a spare USB port and a wired Ethernet port.

Running NovaLCT in a virtual machine or emulator is not recommended: the USB driver that talks to a sending card often fails to pass through, producing the “hardware not detected” error that sends technicians hunting for a fault in the screen rather than the PC.

To start using NovaLCT you need to download and install the correct version of the Novastar software on a Windows PC. The download itself is straightforward; choosing the right version causes the most support tickets.

The current release in NovaStar’s official download centre is NovaLCT V5.9.2, supplied with a matching synchronous-control manual, a multimedia-player manual, and release notes. For most new projects on supported hardware, that is the right starting point.

“Newest” is not always “correct”, however. A screen commissioned with an earlier release, whose receiving-card firmware has not been updated, may behave better on the version it was originally configured with. Before changing software on a working display, export the receiving-card parameters and screen-connection data, and record the software and firmware versions you are leaving behind.

If your screen uses a sending card connected to a PC, read the synchronous manual; if it uses a player that stores its own content, install the same package but follow the multimedia-player manual — the login steps differ.

Installing Novastar software NovaLCT takes a few minutes, and no licence key or activation step is required.

1. Go to the NovaStar support or download page and select Software for your product series, such as LED Control System or Multimedia Player.
2. Download the NovaLCT package — normally a ZIP archive.
3. Extract it to a local folder such as C:\NovaLCT, then right-click Setup.exe and choose Run as administrator.
4. Follow the prompts. If Windows Firewall asks about network access, allow only the network profile your LED control environment uses.
5. Keep the original ZIP until installation completes successfully, so you can reinstall if a driver step fails.

After installation, connect your NovaStar device to the computer by USB or Ethernet. Windows should recognise it using the drivers supplied with NovaLCT. If the device is not detected:

• Open Device Manager and look for unknown devices under “Other devices”.
• Reinstall the drivers manually from the Driver folder inside the NovaLCT installation directory.
• Confirm Windows is fully up to date and that you are not running the software in a virtual machine.
• Disconnect other controllers and test with a single device first — duplicate IP addresses are a frequent cause of detection failures.

No. NovaLCT is officially supported on Windows only, with Windows 10 or Windows 11 64-bit recommended. There is no native macOS or Linux build from NovaStar, and running Novastar software NovaLCT through a virtual machine or emulator commonly breaks the USB driver the sending card depends on.

If you work on a Mac, keep a dedicated Windows PC or partition for commissioning. Where a screen must be configured from a Linux server room, the player-based workflow — configure once from Windows, then manage content through the player or cloud — avoids the problem entirely.

A very common question about Novastar software NovaLCT is why the screen configuration options are greyed out. In most cases the software is waiting for you to log in: basic monitoring works without credentials, but screen configuration, calibration, and advanced settings sit behind a user login.

Open NovaLCT, then go to User > Advanced Synchronous System User Login. Enter the default password admin and click Login — the advanced menu items for screen configuration, calibration and colour tools then become available. If you only need to check whether a sending card is online, skip the login: NovaLCT shows its quantity and status as soon as the hardware is connected.

Multimedia players use a different login path. The credentials belong to the player rather than to the NovaLCT software, so the default depends on the model and its configuration. Check the multimedia-player manual for the model you are working with, and confirm whether the integrator set a custom password.

If the default password does not work, it has been changed. There is no universal reset code for Novastar software NovaLCT, because the credential protects the screen’s configuration rather than the software. Ask the integrator who commissioned the display, check the project documentation, or follow the reset procedure in the manual for your model.

Carry this into the next project: record the working password, software version, and receiving-card firmware version with the project files. That removes the most common cause of a maintenance visit that starts with a locked-out technician rather than a broken screen.

Connect your PC to the sending card using a USB or Ethernet cable and confirm every device in the chain is powered. Novastar software NovaLCT detects the sending card automatically once the link is up. On a screen already in service, photograph the existing configuration before changing anything — restoring a working setup from a photo beats rebuilding it from memory.

Open the LED display software NovaLCT and go to User > Advanced Synchronous System User Login. Enter the password — the default is admin — and click Login. Basic monitoring can skip this step; screen configuration cannot.

Navigate to Settings > Screen Configuration, select the communication port connected to your sending card, then set the input source type, resolution, refresh rate, and bit depth.

• An 8-bit input source bit depth is the recommended starting point.
• Match the sending card resolution to the screen resolution so the image maps pixel for pixel.
• Click Send to apply the settings, then verify the result on screen before continuing.

Once the sending card is configured, the receiving cards decide what the screen actually shows. Novastar software NovaLCT offers two ways to configure them, depending on whether a known-good file already exists for your modules.

If the module type has been commissioned before, loading the saved file is much faster. On the Receiving Card tab, click Load from Cloud or Import, select the .rcfgx or .rcfg file matching your module specification, then send it to the hardware over Ethernet or by physical address.

Keep the original file for every module type — mixing files between different modules quickly produces uneven brightness and colour that no adjustment will fix.

When no saved file exists, click Smart Settings on the Receiving Card tab and follow the guided steps:

1. Set the module chip, data type, and pixel quantity.
2. Configure the row decoding type and hub mode.
3. Use the grid to map the flashing pixels until the outline matches the physical module, then send the configuration to the hardware.

Work on one cabinet at a time: when a parameter is wrong the flashing-pixel display shows it immediately.

With the receiving cards configured, open the Screen Connection tab and describe the physical screen: choose a standard or complex screen, set the cabinet layout, then connect the cards and cabinets logically so NovaLCT knows which data port feeds which part of the display. If one cabinet shows the wrong part of the image, check the screen connection before the receiving-card parameters.

Sending a configuration and saving it are two different operations, and confusing them is one of the most avoidable mistakes in Novastar software NovaLCT.

Send pushes the current settings to the hardware so you can see the result immediately. Save writes them into the sending card’s memory so they survive a power cycle. A configuration that is sent but not saved can look perfect during the session and revert the next time the screen is switched on. After configuring the input source, click Save, then accept the prompt to store a backup file.

A complete backup — receiving-card parameters, screen connection, and sending card settings — turns a serious fault into a short maintenance visit. Store it with the project documentation, not only on the laptop that commissioned the screen, and record the Novastar software NovaLCT version that created it. Confirm the file opens in NovaLCT before filing it away.

Day-to-day work in Novastar software NovaLCT usually means checking the screen configuration rather than rebuilding it. Open Settings > Screen Configuration to confirm the input source resolution, refresh rate and bit depth, and check the cabinet layout still matches what is installed.

Go to Settings > Brightness in the menu bar, or click the Brightness icon on the toolbar. From here you can adjust:

• Brightness — the overall output level of the screen.
• Gamma — the grayscale curve, which controls detail in shadows and highlights.
• Colour temperature — choose a preset or set a custom value.
• Colour space — select PAL or NTSC, or define a custom space.

Click Save to HW when satisfied, or the change disappears at the next power cycle.

On the Brightness page, select Auto Adjustment and click Wizard Settings. Build a rule that changes brightness by time of day, or connect a light sensor and set a brightness mapping table so the screen responds to its surroundings. Choose Software mode if a PC stays connected, or Hardware mode if the sending card should run the schedule independently — the better choice for an unattended installation.

Open Tools > Monitoring in the menu bar, or right-click the taskbar icon and select Open MonitorSite. The interface shows sending and receiving card status, temperature, voltage and fan speed, module abnormalities such as dead pixels or communication errors, and network state. A topology diagram shows how devices connect, and abnormal items are highlighted.

Use Configuration to set the refresh period, define alarm thresholds for temperature and voltage, and configure email notifications. On modules fitted with a supported monitoring chip, module-level temperature, voltage and bit error rate can be tracked against their own thresholds.

Most problems that send people searching for help with Novastar software NovaLCT fall into a few categories. Work through them in order — changing several parameters at once is the fastest way to lose track of what actually fixed the fault.

Check the USB or Ethernet cable and confirm the device is powered, then check the driver, the Windows network adapter, and the IP configuration. Duplicate IP addresses are a common cause, so test with one controller first — a successful physical link does not prove the software, driver, and firmware are compatible.

Verify the cabinet dimensions, receiving-card parameters, scan settings, data-flow order, refresh configuration, and cable path. Test one cabinet at a time and document the result before applying it to the rest of the display.

Confirm every cabinet uses the intended receiving-card file and the same approved brightness, gamma and colour settings, and keep the original calibration coefficients before applying new ones.

Verify the exact hardware model, firmware package, communication path and power stability, and never disconnect power during an update. Schedule firmware work in a maintenance window with a known-good backup.

NovaStar publishes several tools, and knowing which to open first saves time. Novastar software NovaLCT is the configuration and maintenance layer; content publishing, cloud management, and simplified processor control are handled by other applications.
