Just as the title reads, I'm unable to turn on HDR through windows display settings. As soon as I toggle it on, it immediately turns itself back off. The display is the Vizio M658-G1 And it does support HDR. I thought maybe I was using the wrong port, but in order to rule that out, I tested it on every port. When I go to the TV's input settings on turn on UHD the screen goes black and the PC stops reading the TV as an output. I've been trying to fix this for months and can't find anything online. At one point I thought my GPU was too weak to display 4K HDR but I've since upgraded to a 3070ti and no luck.
*I don't have another HDR display to test with.
