HDR setting in Windows 10 won't stay enabled

Hello,

I recently purchased an HDR/4K-compatible graphics card (a GeForce 1080ti). I have a 4K HDR display (LG C7 65" OLED). When I first installed the card and drivers, the HDR option was turned on by default, and I was getting an HDR signal to the display. However,
the resolution was set to 1920x1080. When I changed the resolution to 4K, HDR turned off. Since then, I have been unable to get HDR enabled again. When I try to enable HDR, the setting just turns itself off again, like so:

Recordit: Record screencasts fast & free! with GIF Support!

This is not an issue with my display or receiver, as I'm able to get HDR out of my PS4 just fine, and I don't believe it to be an issue with my HDMI cable either, since I was getting HDR out of the PC when I first installed the card.

I'm not sure what other steps to take. I ran dxdiag, and it appears that it's not detecting the full color range:

Display Color Space: DXGI_COLOR_SPACE_RGB_FULL_G22_NONE_P709 (as per this article: https://support.microsoft.com/en-ca/help/4040263/windows-10-hdr-advanced-color-settings).

From that same article, it appears to be detecting the display as HDR compatible:

Monitor Advanced Color Capabilities: BT2020RGB BT2020YCC Eotf2084Supported AdvancedColorSupported

Thanks for looking, any help would be greatly appreciated.

 

Windows HDR option within Windows 10 settings. Poor display quality when enabled.

Hi John,

I found this solution:

-Please go to NVIDIA control panel> display> adjust video color settings

-Use gamma YCbCr422 10/12bpc (deep)

-With the NVIDIA settings

-Set the dynamic range to full

Click apply

Under desktop settings:

Gamma +1.4

Digital Vibrance +60

then go to windows control panel, screen, and set HDR and advanced color to HDR, if everything is OK, it will stay on.

If you are using MPC-HC to watch movies, add the render MadVr and in the Display settings for HDR, use passthru

This works very nice for me.

Hope you find this usefull.

Godspeed!

Thank you thank you THANK YOU!!! It made a heaven an earth difference!!!!

Guys, this is DEFINITELY a gamma and calibration settings issue on the Nvidia control panel! I changed my settings to:

Contrast: +100

Gamma: +2.00

And now everything is GORGEOUS!!!!

 

HDR won't enable!

This sounds like the exact same problem I am having, just different hardware. TV is a Sony XBR65X930C. When set to 3840x2160 I see the option to turn on HDR in the display settings but attempting to turn it on results in my TV flickering and the option going
back to unchecked. If I set the output resolution to 1920x1080, I can finally enable HDR and it stays enabled but it appears applications are still having trouble properly enabling HDR (need to test more).

All drivers and TV firmware are up to date. I can confirm I can get 4K HDR to work on that TV using other devices like a PS4 as well so the capability is there. Just not sure how to get it to work correctly on my PC.
