thunderbolt – 2022 Apple Mac Studio M1 Max w/ dual displays 4K@144 Hz

Spread the love

I just received a 2022 Mac Studio M1 Max, additionally I purchased a Thunderbolt 3 to dual DisplayPort 1.4 adapter: OWC Thunderbolt Dual DisplayPort Adapter

When attempting to connect both displays, the first one connected will take 144 Hz, while the second is capped at 95 Hz. I verified both monitors (LG GN950) support 4K 144 and the cables support DisplayPort 1.4 DSC by connecting to my gaming PC w/ a 3080RTX.

Lastly I ordered Thunderbolt 3->DisplayPort cables to check if it’s just the adapter that doesn’t work. However, input from anyone with experience would be much appreciated.

One more thing: Macs and 4K 120 Hz displays compatibility list

Someone shared that they have an M1 Ultra w/ 2x 4K displays at 144 Hz, but no detailed config information
