The USB4 protocol can handle 160Gb/s split asymettrically (so, say, 120Gb/s out, 40Gb/s in), wheras the upper limit for DisplayPort’s highest bandwidth mode, Quad UHBR 20, is 80Gb/s in one direction. So you can saturate your DisplayPort 2.0 quad-channel with more than enough bandwidth to power three 10K 60Hz 30-bit (i.e. very high-end) monitors in DSC mode, and still only be using half the bandwidth of USB4, all using a single cable which I can also use to charge my earphones.

14·6 days agoI know, right? Why deal with Problem X when Problem Y also exists?
Agreed. It’s a pity, then, that no-one has invented a single port that can replace USB-A, DisplayPort, HDMI, propriatary power connectors, Thunderb… oh… wait…
