I do not have a 2020 MacBook so I cannot test but the Pro Display XDR is not 5120x1440, it is 6016x3384. The problem with my current MacBooks ('14 15" RMBP and '17 13" MBP, both with Intel Iris graphics) is that while they can drive 4k displays they cannot drive the 5120x1440 resolution specifically.
This limitation is specific to the MacOS drivers. Windows in Bootcamp is able to drive 5120x1440 on these devices.
Yeah I read through all those. It’s a work laptop so I’m not comfortable doing things like disabling SIP or mucking around in any system settings. That machine is my livelihood so I don’t mind finding devices that just work.
