Windows 10: HDR content not being displayed properly

Hi,


My windows 10 always send fake hdr metadata 1000/20 metadata instead of the actual MaxCLL/MaxFALL and bogus 1000/0.030 instead of actual Max/Min DL which make HDR content look blindly over bright, while playing the same HDR content with My TV internal player things look normal. HDR games also look over bright bcs of this bug.


Regards

HDR fullscreen problems

Version: Windows 10 17134

GPU: NVIDIA 1080 Ti (Driver 397.31)

Display: LG OLED 55" B6P

Problem: Windows HDR implementation barely works properly. Here's a list of issues I've seen so far:

1: SDR applications that are not exclusive fullscreen start in HDR mode, distorting the colors. If an OS overlay [such as the volume overlay] come up, the display will go blank until the overlay dissapears.

2: SDR applications that are exclusive fullscreen go blank. From what I can see, my display is in SDR mode, so I'm guessing there's a mismatch between Windows trying to output HDR content and the display receiving it. [And no, the problem is on Windows
end; the display can handle HDR just fine on other systems]

3: I've had a case where an SDR application, on exit, somehow resulted in the system HDR setting being disabled. I've also had another case where on exit the system is reporting its in HDR mode, but outputting SDR even on the desktop.

So in short: Windows is not managing HDR properly.

windows 10 and HDR


i have the creators update and HDR ready hardware. i want to play a full UHD BR rip. i'm using media player classic home cinema and madVR. should i be using RGB full in the nvidia control panel or one of the ycbcr settings? when i wanted to play an HDR game i had to use ycbcr but i hear it's not the same for video. the windows HDR setting under display settings will not turn on when using RGB. i hear windows is suppose to automatically detect HDR content and switch to the correct settings but it has a history of not working properly and not sure how to go about getting HDR movies to properly display.
