Image Processing Features
Three Independent 4K Layers
The CX40 Pro supports up to three independent 4K layers. Operators can adjust layer priority in Z order, making it suitable for multi-source layouts, picture-in-picture presentations and complex LED canvases.
Flexible Image Scaling
Choose from three scaling modes: custom scaling, pixel-to-pixel display and snap to canvas. These modes help preserve source detail or quickly fit content to the configured LED screen.
Color Replacement
Replace a selected color in the image without changing the performance of other colors. For the most visible result, use a highly saturated source color.
14-Channel Color Correction
Fine-tune the hue, saturation and brightness of black, white and 12 standard derivative colors based on the red, green and blue primaries. This gives technicians more control when matching cameras, content and LED panels.
RGBW Curve Adjustment
Adjust the image’s RGBW mapping curves to refine tonal response and achieve more consistent image reproduction across the LED display.
Where Is the NovaStar CX40 Pro Used?
- Large-format rental LED screens for concerts, conferences and live events
- Broadcast studios and production environments that require 12G-SDI and Genlock
- Control rooms, command centers and visualization walls
- Virtual production and multi-source presentation systems
- Fixed LED installations that need high pixel capacity or fiber transmission

Frequently Asked Questions
What is the NovaStar CX40 Pro?
The NovaStar CX40 Pro is a 4K LED display controller and control server for the COEX system. It accepts HDMI 2.0, DP 1.2 and 12G-SDI sources and sends the processed signal to an LED display through 5Gbps Ethernet or a 40Gbps optical connection.
How many pixels can the CX40 Pro control?
The six 5Gbps Ethernet outputs provide a total loading capacity of up to 9 million pixels. The final canvas configuration depends on the LED system design and connected receiving hardware.
Does the NovaStar CX40 Pro support 4K input?
Yes. The controller provides HDMI 2.0, DP 1.2 and 12G-SDI input connectivity and supports up to three independent 4K layers.
Can the CX40 Pro transmit LED signals over fiber?
Yes. Its 40Gbps optical output is designed for high-bandwidth, long-distance transmission in large venues and installations.
Does the CX40 Pro support Genlock?
Yes. It includes one Genlock input with loop-through, which helps synchronize the controller with other video and broadcast equipment.
Which input bit depths are supported?
The NovaStar CX40 Pro supports 8-bit, 10-bit and 12-bit video inputs.
