1. What Is Novastar NovaLCT?

NovaLCT is Novastar’s professional LED display configuration software. It is used to manage:

• Receiving cards
• Sending cards
• Monitoring cards
• LED brightness, power, and error detection
• Real-time display control

It is widely used in LED video walls for advertising, rental events, broadcasting, control rooms, and stadiums.

You need the following to use NovaLCT:

• A Windows PC

• NovaLCT installation package
• Antivirus software disabled (recommended during installation)

1.1 How to Download NovaLCT Software

To install NovaLCT:

Visit the official Novastar download page.

Download the latest NovaLCT version.

Complete installation including drivers.

When Windows Firewall prompts, allow access.

2. Graphics Card Settings

Before configuring your LED display, your Windows graphics card must be set correctly.

2.1 Choose Display Mode

When connecting your LED screen:

Duplicate Mode (recommended)

Shows desktop icons and helps confirm screen connection.

Extended Mode

Shows desktop background only.

Selecting Duplicate Mode ensures easier troubleshooting.

2.2 Adjust Display Settings

Right-click desktop → Display Settings

Set:

Scale & layout: 100%

No image stretching

Output resolution must match LED screen resolution

This ensures the LED screen displays pixel-by-pixel accuracy.

3. Sending Card Settings

3.1 Basic Login Steps

Open NovaLCT → Click User → Choose:

Advanced Synchronous System User Login

Password: admin

Then click Screen Configuration.

If only one sending card is connected, you do not need to manually select a communication port.

3.2 Video Source, Resolution, Refresh Rate

Select:

Video source (HDMI / DVI)

Correct resolution

Matching refresh rate

Important:

The resolution and refresh rate must match both:

Graphics card output

Sending card settings

Click Set, then Refresh, then Save.

4. Receiving Card Configuration

4.1 Using RCFG File (Recommended)

If your LED display supplier provides an RCFG configuration file, simply:

Click Load from File

Send parameters to all receiving cards

Save configuration

This is the fastest and most accurate method.

Sending options include:

Send to all receiving cards

Send to a specific receiving card

Reset starting coordinate

4.2 When You Don’t Have RCFG Files

If your LED display is already showing normal images, data is stored inside receiving cards.

You can:

Use Read Back

Save the extracted RCFG file

Apply it to new receiving cards later

This is effective for screen maintenance and card replacement.

5. LED Screen Connection

After sending card and receiving card configuration, your LED screen will still show only part of the desktop. You must complete the screen wiring configuration.

5.1 Basic Steps

Select the number of LED screens (usually one)

Enter the number of receiving cards in rows and columns

Select sending card

Enter receiving card size

Make the connection manually or use Quick Connection

Send data to hardware and save

You can also save the configuration file for future use.

5.2 Enable Mapping

This function helps visualize the wiring order of receiving cards.

Useful when:

Technicians are unsure about cabinet order

Rental LED screens are on site and need fast mapping

"P" indicates the output port number, and "#number" indicates receiving card order.

(Some receiving cards do not support this feature.)

5.3 Detect Communication Status

This tool helps identify faulty modules, bad cables, or disconnected cabinets.

Green: communication normal

Red: connection issue

Useful for on-site troubleshooting.
