Try this....
but game in borderless windowed -> open browser in corner of display over the game. -> open a hdr video on youtube:
Now check in the background if it looks normal to you.
It's a weird bug I had too.
If you put the game in windowed mode then ALT+TAB it will be like 'regular' HDR brightness that you want where the colors are much more vibrant in the game in the background. When you ALT+TAB back in, the game will go back to being smudged up. So to fix this...
1...-> Turn off FreeSync if you don't have FreeSync 2/Premium or its equivalent, GSYNC (Ultimate). HDR support with VRR enabled with non 'premium' VRR monitors is not good. Additionally If you are running at 4K.. You NEED to cap your frames @60FPS. Unless you have the newest display standards that output HDR above 4K@60. I believe that is exclusive to HDMI 2.1
2... -> HDR=ON in Windows and in game... Set the Lightning effects in game in (Accessibility) = ON. It will make the game darker.. but the gamma is better. (Less washed out). Trust me on this. Also turn gamma correction in (Display/Graphics) settings = 0/100. Your game will be darker then ever now.
3...-> [ALT + TAB] then go to YouTube, put it in a small window over your game, and search up a HDR Video. Whichever one works. Your desired HDR settings will blast on. With the game running in the background, you will see that it corrects itself. (I was like wtf?? when I saw this lol.)
4...->NOW HIT [WIN+ALT+B]. This will turn HDR in Windows off. Then you hit [WIN+ALT+B] again to turn it back on. Then [ALT+TAB] into the game and pray it works. If it doesn't, try again.
5...-> Now with the corrected REAL Vibrant HDR... You can adjust your monitor brightness, color corrections, + in game gamma correction to your flavor.
Yes. you will have to do this every time.
Jesus christ WHATABOUTMEBOSS, that's crazy. You actually got it to work by doing that?
First off, great job for finding any fix, but as another has pointed out, it's simply too much for most people, including me. I only have a few spare hours in the day...
Also, HDMI 2.1 has more than enough bandwidth for 4k 120hz 10-bit 4:4:4. In fact I've overclocked my S95B to 144hz and I can still get full chroma HDR at 4k. HDMI 2.1 is literally the best option we have right now, highest bandwidth, until Displayport 2.0 comes out with the new AMD GPUs in a couple of weeks.
And yeah, playing an HDR youtube video is the easiest way to see if HDR is actually working. Especially for me, as I run the SDR brightness in windows HDR settings at zero. This keeps my screen at about 120-150 nits for everyday desktop use, which is more than enough for such a giant screen and doesn't risk burn-in as much on the OLED. So then I never have to change any setting when I want to view HDR content, as my screen and computer are already perfectly tuned for HDR. SDR is dark, which contributes to Unbound looking so bad, but all HDR gaming or video content is bright as !@$#. That's another reason why I don't want to have to re-balance all my colour settings anytime I launch Unbound.
