Trying to figure out why plugging in an HDMI cable to my video cards turns off HDR in Windows 22 and won't let me turn it back on. Or rather does, then after a second turns it right back off on its own.

I could swear I did this in the past.

nvidia 3070. Primary display is a Alienware AW3423DWF over displayport, second display is literally a 4k TV over HDMI.

I don't care about HDR on the TV I just want to be able to have it on my gaming monitor but also have the TV plugged in.

hmm. Could be a windows problem. Eliminating the HDMI connection, even if the cable is to an older HDR standard, the DP connection should easily support all forms of HDR since they are more cable agnostic than HDMI is. Windows 11 is a bit of a buggy shit...

Have you tried backing your gaming monitor off of 165hz down to something like 60 and seeing if it allows HDR then? Could be hitting some unexpected cable limit and it's backing off from HDR.
