Has anyone tried dual 4K @ 120hz?

Sorry if this is the wrong place to ask, but I'm interested to hear experiences of people with dual 4K @ 120hz screens.

Any luck so far?

I don’t mind but might be hard to discover. Reposted here https://twitter.com/nikitonsky/status/1462901714680532997?s=20

Specifically, on M1 macs (I am waiting on a base model 14" macbook pro)

I have dual 4k @ 144hz screens and it's been working flawlessly on my M1 Max. Both are running over USB C (Thunderbolt 4) -> Displayport.

I'm running a pair of Acer Predator XB3's (XB273K GP) on a base model 2019 16" MBP. I was a little worried about fan noise going into it, but while the fan is audible, it isn't distracting or worrying.

I might try to somewhat hijack the issue. I'm currently running iMac 27 2020 + 2x 4k@60. The upgrade path for me would be Mac Studio + 3x 4k 120Hz.
Is this even in the realm of possibility?

According to the docs, Mac Studio should handle 4x 6k@60, which requires more bandwidth than 3x 4k@120. But then with Apple , you never know :)

I've since upgraded to using 3x 4k@120 displays with my 2021 MacBook Pro (M1 Max) and it works flawlessly. I'd have no reason to suspect the Mac Studio wouldn't be able to do the same 🙂

Awesome. Glad I asked. Any specific displays?

I have 3 of these: 27'' UltraGear 4K UHD

Exactly the ones I was look at. Thank you.
