What are you talking about? Animators don’t need higher refresh rate. 60Hz is totally fine and most studios can prove it. If you think otherwise than you clearly are not from the industry.
…It’s possible for monitors to have 5K/6K/8K 120hz with Thunderbolt 5, DisplayPort 2.1 and HDMI 2.x with or without DSC.
They didn’t want to and decided to be cheap or be content on ruling out devs and animators being accommodated in that way.
Asus ProArt typically reserves high refresh rates to those two audiences.
I know having the PA32UCG that has 4K@120hz but also 1000 sustained nits and HDR1600 certification for its 1600 peak nits.
Note it’s expected for the next Pro Display XDR to have Pro Motion (120hz).
