hdr400 Are HDR400 panels bad?

[Allptraum1989]

I want to buy a new monitor. I have found a nice one.

Coincidentally it has HDR400. I know, HDR400 is crap. But i don't care about this feature AT ALL. I just want a monitor of this specifications and turns it it ONLY comes with HDR400. No option to order without it.

But my question is, will i be fine by just disabling HDR400 or will i actually get a worse display?

Are HDR400 panels more prone to things like ghosting or blb? (While HDArent is turned off)

 

Best regards

hdr400 is basically a rating, like 90% DCI-P3 is.

It's not something you can disable.

 

It's a thing that tells you that the backlight of the LCD monitor is powerful enough to reach 400cd/m² and that the monitor doesn't support controlling the backlight brightness using zones.

You don't have to enable HDR or use 10bit per color, you can use the monitor just like a regular standard monitor.

 

400cd/m² can still be better than monitors without this HDR rating.

 

See https://displayhdr.org/ and also see https://displayhdr.org/performance-criteria/

90% of some gamut, is not "rating". It's coverage, or size of color space.

 

So 90% DCI-P3 means:

- color gamut cover 90% of DCI-P3 (but size/volume can be 101% DCI-P3)

or

- size/volume of the color gamut is 90% of DCI-P3 (but it could cover only 80% of DCI-P3)

 

Sometime cover = size/volume .
