The led video processor is a dedicated video processor for the led display. With the improvement of people’s requirements for the quality of the display screen, the manufacturer camera has launched 4K led controllers and 4K led video processors. Novastar 4k processor-HDR Master 4K is a professional video processor specially designed for 4K led video walls.
Why does your display need a video processor? What can it do to your display? What are the functions and features of the Novastar 4k led processor of HDR Master 4K? We will answer you in detail in this article.
What is Novastar 4K processor?
The main task of the LED video processor is to convert the external image signal into a signal that the LED display can accept. Resolution conversion, image scaling, and color space conversion are performed during this process. So that the presentation effect of the led display is more perfect.
SDR and HDR
Before we get to know the nova 4k processor of HDR Master 4K, let us first understand two concepts: HDR and SDR.
SDR, the full name is Standard-Dynamic Range. SDR is a traditional video image standard. Its dynamic range is much smaller than what the human eye can perceive. Therefore, the picture details are not perfect. SDR’s display of the level of color saturation of the picture is not as good as HDR.
HDR, the full name is High-Dynamic Range. This technique was first used in photography. Turning on HDR when taking pictures can brighten darker scenes. Currently. The field of Led displays has also ushered in the HDR era.
Compared with SDR 1080P display technology, HDR display technology has a higher pixel load.
As you can see from the comparison chart below: HDR has a higher luminance dynamic range, showing more detail in highlights and shadows. The picture on the right is fuller, and the color transition is smoother.
How does the Novastar 4k LED processor work?
Nova HDR Master 4K led processor analyzes various SDR content, so that indicators such as high dynamic range, color gamut, and color bit depth reach HDR standards.
In addition, it can convert the SDR video source format to HDR 10. So the video screen can display richer colors and give the audience a better viewing experience.
Don’t worry if your display doesn’t support the HDR standard. You can enhance the dynamic range of brightness and color gamut through the “Image Quality Enhancement” function.
Then you can get an HDR-like display. Moreover, with a 4K-level controller and A8s receiving card, a full-link HDR solution can be achieved.
HDR Master 4K Novastar video processor is loved by many customers because of its excellent image processing capability. It is widely used in high-end rental, stage control, small-pitch led display and video source format conversion, and other fields.

What is the HDR requirement for the display?
- HDR-enabled display systems must have a color depth of 10 bits or more
- The peak brightness of the screen must be at least 800nit
- The current industry’s fine pixel pitch led display series can reach 14 or 16bit color gradation
- For color gamut selection, the BT.2020 wide color gamut standard is good.
- The output quality of the screen is also related to the HDR live video source
HDR was previously commonly used on TVs, computers, and other monitors. Since Samsung introduced HDR technology into led displays in 2017, the display industry has seen a new development opportunity.
NovaStar 4k processor-HDR Master 4K, with professional LED controller, A8s receiver card, can realize NovaStar HDR full link solution.
