I had a similar problem with very dark HDR image when I first attempted HDR gaming. Are you playing on Xbox? If so there is the YCC422 video setting that can cause issues with displaying content. I had success with this off. Check video details in the Xbox settings to see if you have all check marks green. Next, check to see if your KS8000 firmware is up to date. Out of the box, in “Game” mode, the backlight would have to be changed manually every time when the panel switched from SDR to HDR and back. Firmware has remedied this but you will have to manually setup SDR, then HDR settings at least once. In a well lit room I run Backlight at 10 for SDR, and 20 (max) recommended for HDR. Brightness, color, contrast just under the backlight, I use the same as this site. Turn off all the post processing. Enable UHD color, Smart backlight to High. Dynamic Contrast off for SDR and Medium for HDR. Use the 2point white balance numbers and custom color settings from this site… or Auto color, but never Native… it’s oversaturated. All from memory here so I think that covers it. Proper HDR viewing is still fantastic on this panel. Good luck.

So these settings provides a fix to the YCC422? Does it switch to back to RGB on the Xbox?

Yes, I’m playing on an Xbox One X. I’ll have to check the YCC422, no idea what that is. I know from memory all the boxes are checked green and the TV is up to date as the backlight automatically goes to 20 when displaying HDR content. I always keep Color Setting on auto and typically turn dynamic contrast off or low. Also, UHD color is certainly enabled… Thanks for the response, I’ll compare your suggestions to my TV settings and see if the results are any different.

HDR Looks Dim

The TV does not know how to correctly display video content in hdr. All colors look dull and lacks brightness. Despite the fact that the image brightness is declared by the manufacturer to be 1000 nits. The HDR parameter cannot be turned off from the TV menu When watching a movie in full HD everything is fine

Closest I got with my (reference) OLED laptop is Gamma at 2 or 3 and Color at 63 and Auto for Color Space. You need to set your values while watching HDR content.
