HDMI 2.1 4K 144HZ HDR Support? - Blu-ray Forum

erik343 · 12-26-2022, 01:58 AM

I was thinking about buying a 4K 144HZ HDR TV/Monitor with HDMI 2.1 ports.

Do these HDMI 2.1 ports support 4K@144HZ HDR? or just 4K@120HZ HDR? (With no compression like DSC?)

I also currently have a 4K 144HZ HDR with two Display Port 1.4 ports (and two HDMI 2.0 ports) and also with DSC, but my video card does not yet support DSC.

I was wondering if I upgrade my video card (to support DSC), does the DP 1.4 cable interface support 4K@144HZ HDR with DSC?

My 4K resolution is 3840 x 2160...

On paper it looks like HDMI 2.1 does support 4k at 144hz without compression. Obviously don't take that as gospel and double check any gear you want to buy.
