    Windows 10 1803 HDR problem


    Hi guys I recently upgraded to 1803 and I'm having issues with the colour and bit depth when I turn on HDR.

    I have a LG b7 10 bit TV and a Geforce 1070 and when I used to turn on HDR or play an HDR game (before the update) Windows correctly set the display to YCbCr 422 10 bit.

    Now after the update when HDR is enabled it switches to RBG and 8 bit with dithering in settings>system>display>advanced display settings which is wrong.

    Is there any way I can change this somewhere in Windows so it correctly sets it as YCbCr 10 bit?

    I know I can set it manually in the Nvidia control panel but that has to be on "use default colour settings" so it switches back to RBG full automatically for non-HDR games.

    :)

    HDR Washed out on Windows 10

    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!

    HDR Washed out on Windows 10

    @lynx29 The only games that actually work in HDR are ones that have an in-game toggle option. Other ones like Final Fantasy doesn't work (least it doesn't say it's in HDR on the TV).

    @IceScreamer Tried this already, no dice unfortunately.

    I had hoped it would be fixed with the 1803 update but still nothing.
