Just 60 Hz. Is there a technical limitation that prevents 5K@120 Hz?
Isn’t it a bandwidth issue? If not that, then probably it’s just too expensive to produce for a prosumer-grade product. I think there’s a market for this product, as there’s presumably a market for the Studio Display that they’re trying to compete with, but I would guess that this quickly drops to ~$1000 if they actually want to move these. Making this with a 5k/120fps display would certainly push their price above Apples and I just kinda doubt there’s enough of a market. Pricing it equal to the Studio display seems like they’re just testing the waters but no way can be a long term thing.
Since 8k60 exists, I'm sure at least 90hz would be doable with today's standards
Currently 8k requires two displayport cables or thunderbolt with DSC (compression), which is not optimal
Hdmi 2.1 can do 8k60
As far as data, ok. Haven’t ever looked for an 8k display. Nothing in the Apple world seems to do 90hz though, it’s 60 or 120. I wonder if MacBook Pro support display outputting those high res/high refresh rates also.
DisplayPort 2.0 can 5k/120 with DSC and UHBR 10 cables, or 5k/120 without DSC on UHBR 13.5 cables. HDMI 2.1 can handle 5k/120 with DSC in use.
It's not a bandwidth limitation.
But is there enough bandwidth to spare such that you can still send data back the other way? Pretty much all displays function as a USB hub as well.
Yes. Thunderbolt 5 supports DP 2.1, with up to 80 Gbit/s of bandwidth. A 5k/120 with 10 bit color and no DSC display needs 57 Gbit/s of bandwidth.
