> MacOS cannot drive one 5120x1440 display using Intel display hardware.

For other readers, this is not technically correct. The 2020 13” MacBook Pro can drive the Pro Display XDR with its integrated Intel graphics.



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.


It's possible it is just MacOS doesn't have the EID information.

https://apple.stackexchange.com/a/221498 and https://apple.stackexchange.com/a/233854 has how to fix this. It doesn't sound much fun though.


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.


My 2018 13-inch MBP is driving a 5120x2160 LG 34WK95U-W just fine, over Thunderbolt 3.


Mine too. That’s a completely different monitor and resolution. The problem is specifically with 5120x1440.
