Novastar CX40 Pro LED Controller: Practical Guide for Buyers

The Novastar CX40 Pro LED Display Controller is part of NovaStar’s COEX series, designed to handle video input, processing, and output for medium to large LED screens. This all-in-one solution supports multiple high-resolution inputs, including HDMI 2.0, DP 1.2, and 12G-SDI, while delivering ultra-high bandwidth output via six 5 Gbps Ethernet ports and one 40 Gbps optical port. With a maximum load capacity of 9 million pixels, it ensures smooth performance even in demanding applications.

One standout feature of the CX40 Pro Video Processor is its dual working modes: All-In-One and Send-Only. In All-In-One mode, it handles both video processing and sending, while in Send-Only mode, it focuses solely on output. This flexibility makes it suitable for a wide range of workflows.

Equipped with a 5.5-inch touchscreen LCD, the Novastar CX40 Pro simplifies on-device control, allowing users to adjust settings like brightness, color temperature, and gamma directly from the front panel. For more advanced configurations, it integrates seamlessly with NovaStar’s Vision Management Platform (VMP) software.

When it comes to performance, the CX40 Pro Video Processor stands out with its robust processing capabilities. Here are some key highlights:

The CX40 Pro supports up to three independent 4K layers, each of which can be moved, resized, and reordered using Z-order priority adjustment. This feature is particularly useful for overlaying graphics, videos, and other content in multi-layer setups.

To ensure optimal image quality, the CX40 Pro offers four scaling modes:

• Custom: Allows users to define specific scaling parameters.
• Pixel-to-Pixel: Maintains the original resolution of the input source.
• Snap to Canvas: Aligns the image to fit the screen dimensions.
• Fill Screen: Stretches the image to fill the entire display.

These options provide flexibility in matching the incoming signal to the LED screen without distortion.

Color accuracy is critical for professional-grade displays, and the CX40 Pro excels in this area. It includes:

• 14-Channel Color Correction: Precise adjustments to hue, saturation, and brightness for black, white, and 12 derived standard colors.
• 3D LUT Support: Compatible with .cube files of 17×17×17, 33×33×33, and 65×65×65 grids for fine-tuning video source colors.
• Dynamic Booster: Real-time frame-by-frame analysis to enhance contrast, improve image details, and reduce power consumption.

For applications requiring minimal delay, the CX40 Pro offers low latency processing, reducing the minimum processing latency to 0-frame (less than 1 ms). Additionally, its frame rate adaptive feature supports video inputs ranging from 23.98 Hz to 480 Hz, ensuring consistent brightness and optimal screen parameters across different frame rates.

The CX40 Pro 4K LED Controller provides a variety of video input options to accommodate diverse sources. Let’s break down the available inputs:

With two HDMI 2.0 inputs (each featuring loop-through), the CX40 Pro supports resolutions up to 4096×2160@60Hz. It also supports YCbCr 4:2:0 color sampling, HDR10, and HLG, making it ideal for high-quality video playback.

The single DisplayPort 1.2 input matches the capabilities of HDMI 2.0, supporting 4K resolutions at 60Hz. It’s perfect for connecting computers and media servers.

For broadcast and live event professionals, the CX40 Pro includes two 12G-SDI inputs with loop-through. These inputs support resolutions up to 4096×2160@60Hz and are compatible with ST-2082 (12G), ST-2081 (6G), ST-424 (3G), and ST-292 (HD) standards.

The CX40 Pro also features a Genlock input for synchronizing with other video devices, as well as two Gigabit Ethernet control ports for network communication. These ports support TCP/IP protocol and allow for seamless integration with VMP software.

HDR (High Dynamic Range) is a game-changer for LED displays, and the CX40 Pro delivers exceptional performance in this area. It supports both HDR10 and HLG, complying with SMPTE ST 2084 and ST 2086 standards. This ensures a wider color gamut and deeper contrasts, resulting in stunningly realistic visuals.

In addition to HDR, the CX40 Pro offers impressive color depth options:

• 8-bit, 10-bit, and 12-bit video inputs: These options cater to various use cases, from standard broadcasts to high-end productions requiring precise color grading.
• Full Grayscale Calibration: When paired with NovaStar’s calibration system and scientific-grade cameras, the CX40 Pro generates unique calibration coefficients for each grayscale, ensuring uniformity and enhancing overall image quality.
