Yeah, it's kinda sad how close we are to the specs and that they aren't getting much ahead. Higher resolutions just chew through that bandwidth quickly. Apple

Apple had to really hack around to get the Pro Display XDR to do 6k at 10-bit at 60Hz. They are using USB-C w/Thunderbolt for that and actually pushing two DisplayPort 1.4 signals down that cable. Clearly cludgy at best. Even then at 6k/10-bit/60Hz the other USB-C ports on the monitor can only work at USB 2.0 speeds because the link is so saturated.
6k/10-bit is a bit niche right now for sure, but I'd sure love to be able to daisy-chain my three 4k monitors which I can't do, and 120Hz is becoming very mainstream (although actually rendering 4k/120Hz is problematic on the graphics card side too).
- chx 7y agoI believe Apple arrived to the Prod Display resolution based on the Thunderbolt bandwidth! https://linustechtips.com/main/topic/729232-guide-to-display-cables-adapters-v2/?section=calc&H=6016&V=3384&F=60&bpc=10&timing=cvtrb&calculations=show&formulas=show https://linustechtips.com/main/topic/729232-guide-to-display... it's 38.70 gbit/s which is suspiciously close to the bus bandwidth limit of 40 gbit/s
- amarshall 7y agoIt also is the equivalent PPI of the Apple Cinema Display (which was 2560x1440 27”), but 2x for “retina” monitors. I eagerly await DP 2.0 to become widespread so the rest of the world can catch up to the XDR and LG UltraFine 5K.
