I wonder why everyone holds AMDs display port 2.1 in such high regard. Its barely more bandwidth than hdmi 2.1 since its not the full UHBR20 80GBPS

its UHB13.5 at 54GBPS on RDNA 3 vs 48GBPS HDMI 2.1 on ADA GPUs

48 vs 54 is roughly 12.5% more bandwidth. In the PC hardware world, 12% isn't often considered very close.

That 12.5% increased bandwidth allows this 8k monitor, to be easily run at 240hz 10 bit color with DSC.

That monitor theoretically supports it's full resolution and refresh rate over HDMI 2.1 too, the extra bandwidth isn't the difference maker.

Right now no cards seem to work with it at 240Hz over HDMI, but it's listed as supported on the monitors end.
