Here is my findings from my 2 Macs. In fact I'm thinking of returning the M1. The external hardware here is identical with an elgato thunderbolt3 dock and a dell 6000 connected to it.

2017 Mac Pro HiDPI resolutions of the LG 27UK850 on Catalina 10.15.7
3840x2160
2560x1440
2048x1152
1920x1080
1600x900
1280x720

I unplug the 2017 MBP and plug in M1 running 11.2.3 and I get
3840x2160
1920x1080
1600x900
1280x720

The M1 is 4 days old and i simply can not work at 3840x2160 everything is just to small. The 2 other resolutions above 1920 are missing on the M1. I've also not upgraded to later BigSur releases because I saw Displaylink messages stating that potentially the 3840 would also disappear. I suspect the issues here are probably at Apples end and either the OS or hardware. I'm not sure that Displaylink will be able to overcome these problems. Hence I'll probably send the M1 back just prior to the return period expiring. Seems my Intel Mac is superior for every day work irrespective of how fast a M1 may be......if you need multiple monitors it seems that the M1 is not the device for you.
