windows开启HDR后,桌面显示寡淡,我觉得是win在开启HDR后的SDR内容像是按灰阶16-235输出,所以显示设备工作在0-255范围的看SDR就发灰。我的QD-OLED开HDR后桌面照样泛灰。
如果是连接的电视,可以调HDMI黑色等级,默认自动的情况下,源输出0-255时黑色等级为高(三星的是正常);源输出16-235时黑色等级为低。
black level相当于指定显示设备的灰阶工作范围,可以正常工作0-255,16-235两种范围,默认会根据源自动匹配
我自己改了以后,开启HDR后显示SDR内容就完全正常了,和不开HDR的一样。HDR内容就把黑色等级改回默认

It always bothered me that the HDR on Windows never looked right with the technically "correct" settings.
Technically you are suposed to use:
Full Output Dynamic Range + Black Levels High or
Limited Output Dynamic Range + Black Levels Low
For HDR
(and Black Levels always on Low for SDR)
Thing is, on Windows Desktop with HDR On, if you use either Full + High or Limited + Low, everything looks washed out. But if you use Black Level Low, in some games, you get black crush.
Here's what I found out:
- The image you see on Windows Desktop is a SDR image being artificially converted to and HDR image by Windows, but it's actually "still SDR", so on the Windows Desktop, with HDR enabled, you should always use Black Level on Low and Output Dynamic Range set to Full |
