Fix : install RDM ( https://avi.alkalay.net/software/RDM/) take ur own risk
RDM allow me to select 2560x1440 
Just to share, just incase u r nervous after getting your brand new M1 but monitor resolution disappoint you |
This worked for me.... I moved from a 2018 MacBook Pro and am using the 6950 Plugable dongle on an OWC dock. M1 doesn't detect 1440p like before, RDM allowed me to bypass and select the desired resolution.
I have more cables and StarTech adapter coming that specifically says "compatible with Mac".... not sure why if it works by manually forcing it with RDM that the native DisplayManager software can't make it work...
Now I just have to figure out why when using DisplayLink monitors, the Music app pauses between every new song...........
