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.

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.

[–] LetMeEatCake@lemmy.world 1 points 1 year ago

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.
