42PG20D: Xbox One X on the LG C9 Oled TV doesn’t use HDR for resolutions other than 4K

Thanks again

I think the Xbox only supports HDR for 1440p and 4K, I've never personally seen HDR at 1080.

Are you sure about that? Microsoft doesn’t mention this anywhere. I’ve seen reports from people with 1440p HDR monitors who said were able to use HDR@1440p in Xbox...

I do believe it’s a bug in the Xbox, on 4k TVs it doesn’t allow HDR for lower resolutions.

My use case for using 1440p@120Hz is because of much lower input lag and also less tearing and judder (the TV supports VRR). But losing HDR kills it.

Microsoft should fix this. Perhaps there wasn’t a use case for it before, but now a lot of 4K TVs (Samsung and LG) are popping up with 1440p@120Hz and it’s actually a better experience than 4k@60Hz.

Here is a quote from Reddit by a guy that has a 1440p monitor with HDR working:

Just curious if you ever found a solution to this? I was looking at buying the exact same TV.

I’m unable to play at 1440p with HDR, that was my goal (1440p@120Hz).
