Issues with HDR?

[Marsson]

Anyone else notices how the game sometimes switches from being pretty pale in HDR, to being almost "too" colorful in HDR at other times? I've experienced both, and yesterday the game was pretty pale (but bright, and the TV reports HDR being shown in both scenarios) but today it's extremely colorful again.

I've made sure to see that I enable HDR on the correct output in Windows every time, and restarting the game changes nothing. It's really weird.

If you're using an HDMI cable then you're limited by bandwidth and that's causing the problem (HDR at 4K 60hz requires around 22gb/s and HDMI right now can only provide 18gb/s), so you'll need a display port cable or go to 4K at 30hz.

Windows 10's HDR feature is really buggy so that could also be the problem.

That's not true. Todays HDMI standard can't output HDR, 10bit at 60hz, at chroma 4.4.4 though, that's why you have to use 4.2.2.

Yeah, I suppose it's down to buggy software in Windows. Makes me wonder which appearance is the "correct" one though. I suppose it's the more colorful version, since the other one looked very pale, but I preferred the skintones when it looked like that.

Are you by any chance in Borderless Windowed mode? I'm pretty sure HDR bugs out in games if they are not in Fullscreen.

Not to my knowledge. I haven't touched the ini files, just enabled fullscreen in the options menu.

Hello did you try to set the color in NVCP it helps a lot, go to adjust desktop color setting and try to play with the digital vibrance and gamma otherwise the windows hdr just looks too bad. I found this on this thread

Nah it's not that it looks bad overall, it's the fact that it differs extremely from time to time even though my settings stay the same.

I believe I've finally found something that works for HDR on Windows 10.

When on the desktop and in games that do not have an in-game option to activate HDR, got to Nvidia Control Panel then to Change Resolution.

After that, scroll to the bottom to option 3 and select Use Nvidia color settings. It should be set 32-bit RGB 8bpc Limited by default. Simply change the Output dynamic range from Limited to Full.

I definitely noticed a color change after doing this despite the TV not saying HDR in Info section.

Only do this for desktop or games that do not have an ingame option to activate HDR. If you do, it will look overly bright.

Also, make sure you have HDR on on your TV. In my case it was in Settings - General - External Device Manager - HDMI UHD Color then just select whichever input you have the PC plugged into.

My TV model is a Samsung UN40MU6300 and am now running on the latest Windows 10 build (1803), hope this helps someone!

That is not HDR.


What you're doing is changing the range of darks and lights to use the full 0-255 set instead of 16-235. Traditionally HDMI enabled devices such as TV's only supported 16-235 so a new driver install uses limited dynamic range to prevent crunched shadows and blown highlights in line with the HDMI spec. If you're using a modern display that supports full range and HDMI then you're supposed to change this from the default.
