    Reason for HDR not working in Windows 10?


    When I click to turn on "HDR and WCG" in Display/Settings I get a 'Do You Wish To Keep New Settings Or Revert' message but regardless of what I do it HDR remains turned off with no error message saying that that HDR cant work on my computer or the reason why.


    Now my assumption is it doesnt work because I use a DVI to HDMI converter to connect my pc to my monitor but if I go todxdiag I get this message which tells me that HDR should work

    Can someone explain to me if all I need is a new graphics card with a hdmi port or is there some other problem.

    HDR Washed out on Windows 10

    I have a Sammy 4k HDR TV as a PC monitor. HDR works wonderfully with supported games. You want to switch the tv from PC mode though by selecting "edit" and then select bluray. Now HDR works as intended. Anytime an HDR signal is present the TV works fine. Do not activate it in windows 10. that doesn't work right.

    This might not work for your TV but it is a known documented fix for mine.

    HDR Washed out on Windows 10

    Aha yeah must've not read close enough. But yes it works somewhat, just wish every game would include a toggle for HDR if they support it though.
