It appears that the M1 Max chip still have some kinks with certain displays. Tell us your experiences.
I'll start with my own.
I have the base model Mac Studio (M1 Max) and the Dell UP3218K (7680x4320 / 8K / 4K HiDPI). The display uses two DP1.4 connections where each drive half the panel (3840x4320 pixels). That works in macOS 10.15.7 (Mojave) on my old Mac Pro 5,1 with a VEGA FE.
While the Mac Studio with the M1 Max does correctly recognise both halves for the screen at 3840x4320 pixels it appears to have timing issues and also mirror the entire main display on the extended display.
