So I updated to DisplayLink 1.3 on both my M1 and 15 MacBook Pro 2017. Nice to have a universal binary.

Interestingly the 1440 resolution on my LG 4K display works correctly only 2017 not the M1. So I am back to using Displaylink on only 1 monitor and using a USB-C to Displayport or HDMI adapter directly for the LG. This solution has in is fine for me. I feel it makes the setup more stable in clamshell mode and during boot up.

None the less it would be nice if it worked as it should. I have to play a little further as well I think I noticed a new anomaly on at least 1 of my two computers. Even with the lid shut 1.3 DisplayLink was advertising the built in display on 2017 MacBook Pro, but not my M1. Naturally with the lid shut this display should not be active.
