Title: HDMI 2.1, it's a Big Deal..
Post by: tp4tissue on Thu, 29 November 2018, 12:59:28

HOLD off on those Top end Graphic card purchases a bit.. until the dust settles on this one..

The 2080Ti, for example, shoulllllld get 2.1 support,  but we don't know for sure atm because testing is not finalized.



Currently

HDMI 2.0 (18Gbps)  can not support 10bit/10bit+ 4K HDR with 4:4:4

It can only do  2 out of 3  of the following features simultaneously, all 3 requires ~23Gbps

4K (3840x2160)
4:4:4 (chroma sub-sampling)
HDR (10bit, 10bit+)


the Upcoming HDMI 2.1 will feature 48Gbps   which will be able to do All 3 and more.

2.1 will do:

4K 120hz HDR (10bit) 4:4:4
8k 60hz HDR (10bit) 4:2:0

There's only one HDMI cable in my house and it's unplugged next to my TV in case I want to use it as a second monitor.  Can't remember the last time I did....
