Lack of available resolutions on Big Sur M1 Macs

Like yourself I've noticed there is a distinct lack of resolution modes available on the M1 compared to intel MACs via displaylink. For comparison, I have a LG 27inch (27UK850) connected via USB from an elgato thunderbolt dock. Both Intel mac and M1 are running Display Manager 1.3. On the Intel Mac I plug in and I have many HiDPI options to chooe from but typically I used 2560x1440. If I unplug the Intel and plug in the M1 I only get 4 resolution and non-past 1920x1080. I'll do an exact comparison and post today. Using scaled on the M1 I still can not get 2560x1440. If I use RDM I can but the fonts are all washed out and blurry. No way you could spend 8hrs a day in front of it.

I'm considering returning the M1 as without it doing dual displays there is no real way of getting a clear 2 display solution because the display link option seems to only work if you want really large 1920x1080 screens which sadly is not what I am looking for.
