DisplayPort 1.4 (which TB3/TB4 support as an alternate mode) has enough bandwidth for 5k at up to 144Hz using display stream compression (which Apple already uses for the Pro Display XDR): https://en.wikipedia.org/wiki/DisplayPort#Refresh_frequency_limits_for_HDR_video https://en.wikipedia.org/wiki/DisplayPort#Refresh_frequency_...
- FireBeyond 5y agoWhatever Apple is doing for the XDR (which I own) is not DSC, or not standard. Because DSC has been broken ever since the Big Sur betas. Catalina supported 1.4 and DSC and my cheese grater Mac Pro happily drove 2x27" 4K monitors in HDR @ 144Hz. Big Sur? Nope, you get 95Hz SDR or 60Hz HDR. If you set the monitors to DP1.2 you get 120Hz SDR.
