I have a feeling all 2.1 will add is a half-baked solution for 8K while still being inferior to the always forward-looking DisplayPort spec.Well that's good. HDMI 2.0 seemed to be a half baked solution, since it's not really a more future proof solution. (Not enough bandwidth)
HDMI 2.1 isn't "real" anything. Until displays have HDMI 2.1 chips in them, nothing is real.
Look at Displayport 1.3. "Launched" two and a half YEARS ago and there is not a single display on the planet that has it.
