What is DisplayHDR, and why it's no different than HDR10

To give you an idea: that the device supports the HDR10 protocol is a very important screen requirement for the screen to be displayed by DisplayHDR, so do not measure the same and cannot be compared.

What is DisplayHDR and what it measures

We've already told you that DisplayHDR is a performance definition, while HDR10 and others are decent. A guide to this definition was developed by VESA in accordance with the CTR 1.1 standard, which describes the following lines:

• Functional blur– This feature can reduce energy consumption and produce very dark levels.
• Accurate Display– Ensures clear brightness and color data data, allowing the GPU to amplify the video signal of that particular screen, thus delivering better visual performance.
• Box check in double corner– This is a black scale test that allows for a very accurate colorimeter measurement of black and white levels.
• Color range– The color test features a 10% patch of color test with high light. This test correctly determines the color gamut displayed on a PC using Windows.
• The blended color scheme: With the touchscreen, the luminance volume works with full color display.
• Delta-ITP test– Screen brightness is checked to ensure that playback of content is reliable for original content.
• OSD Identifier– Any display that is displayed by DisplayHDR must clearly show the corresponding paths within its OSD.
• DisplayPort Certificate– Any monitor with DisplayPort must execute this certificate, ensuring that the screen is working properly.

DisplayHDR certificate types

Inside what is monitoring with this certificate we get different levels: 400, 500, 600, 1000, 1400, 400 True Black and 500 True Black. These are its minimum operating definitions according to VESA (and remember that we are talking about minimum, so maximum levels may be much higher than what is shown in this table).

Why not the HDR10, HDR-600, etc.?

As we mentioned earlier, these are contracts, not performance agreements, and even if we interpret them as such, they cannot be defined by the terms. What does this mean? Consider an example.

It can be assumed that the HDR-600 means that the screen can handle the HDR signal, and that the screen can have a light of 600 cd / m2, right? The fact is different, because this protocol does not tell us if this light is part of the screen or completely, and it does not say how long it can withstand this light without the emergence of temperature control techniques.

Therefore, HDR10, HDR-600, and HDR-1000 (and so on) are unexplained explanations. Nothing is created about the path experiments so that producers can basically say whatever they want without being reliable evidence that what they say is true and a guardian follows it.
