HDR Master 4K Video Processor
Exquisite color to reconstruct the details of the world
Novastar LED display

HDR Master 4K is an HDR video generator, image quality optimizer, and 4K video processor. It is capable of converting SDR video into HDR video output, allowing
for a more realistic and lifelike image. When the LED display doesn’t support HDR, it can provide an overall improvement to image quality using “Image
Enhancement” functionality.

Novastar LED display
4K HDR full-link HDR solution

Support for conversion of SDR video source into HDR, providing a more vivid and stunning visual experience. Can provide a full-link HDR solution by pairing
a MCTRL 4K and A8s receiving card. The output load can up to 8K by splicing 4 devices.

Novastar LED display
Detailed Image for a stunning visual experience

Automatic image noise correction, allowing for a more beautiful
image. All-new Black Level adjustment, providing more detail in
dark parts of the image. Flexible adjustment for Contrast Gain and
Low Grayscale Gain, avoiding overexposure in bright areas and
grayscale loss in low brightness.

  • Image enhancement without reducing loading capacity by 50%

    When the LED display doesn’t support HDR, brightness and color gamut can also be optimized using “Image Enhancement” functionality, allowing any screen to easily achieve an HDR-like display effects.

The HDR Master 4K is a video processor converting SDR content into an HDR format. By analyzing the SDR content and then intelligently filling in the missing information, the HDR Master 4K raises the dynamic range of brightness, color gamut and color depth to HDR standard. With this all-round upgrade, the SDR video source is converted into an HDR10 format which has a wider dynamic range of brightness, more colors and richer bright and dark details. The HDR Master 4K provides full 4K×2K@60Hz input and output connectors. Based on a pure hardware system architecture, the HDR Master 4K allows for stable and highly-efficient processing capabilities, output connector converting, SDI mosaic as well as long-distance optical fiber transmission. Thanks to the powerful capabilities of receiving a variety of video signals, ultra HD image processing and HDR10 image output, the HDR Master 4K can be widely used in applications such as high-end rental, stage control, fine- pitch LED screens and video source conversion.

HDR Master 4K for LED display projects in Malaysia

Short buyer notes from MEGRA (MTV Digital Technology Sdn Bhd, Port Klang). Specs above stay as published. Use this section only to decide fit and next step.

Best for

Projects that need video processing, scaling, switching, or multi-input control for LED walls — control rooms, events, and larger commercial displays.

When to use

Choose HDR Master 4K when the job is more than simple send/play: inputs, layers, or higher-end processing sit in the processor class.

What it connects to

Video sources on the input side and Novastar sending / receiving path on the LED side. System design should follow the I/O list in the specs above.
