I just received a 2022 Mac Studio M1 Max, additionally I purchased a thunderboltThunderbolt 3 to dual Display portDisplayPort 1.4 adapter: OWC Thunderbolt Dual DisplayPort Adapter
And whenWhen 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 4k4K 144 and the cables support Display portDisplayPort 1.4 DSC by connecting to my gaming PC w/ a 3080RTX.
Lastly I ordered TB3Thunderbolt 3->Display port>DisplayPort cables to check if it's just the adapter that doesn't work. ButHowever, input from anyone with experience would be much appreciated.
