I have a 1080Ti and a Samsung 4k TV and I'm trying to get HDR mode working on ME Andromeda (free trial). I have the latest drivers: 384.76. I've tried everything I can think of and the TV doesn't switch into HDR mode. Do I need to have HDR mode "On" in the Win10 display settings? In the Nvidia control panel I've tried setting it to YCbCr422 10bit. Didn't work. What am I missing?
