smileyheadThe HDMI Forum rejected AMD's open source HDMI 2.1 implementation
Sounds like hdmi Forum are a bunch of twats. Time for a new format.
DisplayPort already exists
Altima NEOAnd also USB c
USB-C display output uses the Display Port protocol
Can it use others, and is there a benefit? USB C makes a lot of sense; lower material usage, small, carries data, power and connects to almost everything now.
There’s some really high bandwidth stuff that USB-C isn’t rated for. You have to really press the limits, though. Something like 4k + 240Hz + HDR.
That doesn’t even seem so unreasonable. Is that the limit though? My cable puts a gigabyte a second down it so I wouldn’t imagine that would hit the limit.
It is trivial arithmetic: 4.52403840*2160 ≈ 9 GB/ s. Not even close. Even worse, that cable will struggle to get ordinary 60hz 4k delivered.
I think the maths got a bit funky there. I don’t think a cable capable of such speeds would struggled to do 60Hz at 4K, it surely doesn’t need close to a gigabyte a second?
It surely does. Check pirates post for clean math formatting
USB-C with Thunderbolt currently had a limit of 40Gbit/sec. Wikipedia has a table of what DisplayPort can do at that bandwidth:
en.wikipedia.org/wiki/DisplayPort
See the section “Resolution and refresh frequency limits”. The table there shows it’d be able to do 4k/144hz/10bpp just fine, but can’t keep above 60hz for 8k.
Its an uncompressed video signal, and that takes a lot of bandwidth. Though there is a simple lossless compression mode.
