VESA Releases DisplayPort 2.1 Specification

Are there even display's out with 2.0 let alone 2.1? I know the support needs to come sometime, but I am seeing a storm in a teacup here.

But hey, we all seem to enjoy a little bit of outrage right.

Not yet since there was no need for it, but they are going to come in with 4K high refresh monitors and 8k monitors. Also VR headsets with even higher per eye resolution and refresh rate.

I never said the technology couldn’t work. However for widespread adoption there needs to be strong support from the display industry in a timely manner.

Maybe that’s why NVIDIA stuck with DisplayPort 1.4 with the 40 Series generation.

Ultimately these standards need to be adopted by display manufacturers first. People hold onto their displays longer than their discrete graphics cards.

It’s not like everyone who buys a new graphics card will buy a new display at the same time.

Chicken/egg situation.
VirtualLink is dead though.

Coding + decoding induces latency and should make reprojection techniques harder to achieve.

And let's not forget how all video compression (except for DSC) crushes darks and blacks, which renders it utterly useless for any game with a dark visual style unless the game knows to compensate for this somehow.

Look at the VirtualLink port. The technology was never deployed by VR HMD manufacturers and the port disappeared after a single appearance on Turing generation cards.

True, but then VirtualLink was a technical abomination (not compliant with the USB-C spec due to reallocating the USB 2.0 lanes, which isn't allowed) and has been functionally superceded by plain USB-C with alt mode support. There's definitely a chicken/egg problem of GPUs not having USB-C outputs vs. HMDs adopting the port though, as DP/HDMI-to-USB-C adapters are rather expensive and somewhat complex, meaning you can't just bundle them cheaply. I definitely hope we see more GPUs with USB-C outputs though.
