    Has anyone else has success with using multiple displays while running Ubuntu 20.04.3? Currently, I have one display that works normally, and two additional monitors that Parallels only recognizes at half their actual size. MacOS does not have this issue with the displays, it recognizes them without issue, only in Parallels.

    There is a problem with Linux in Parallels detecting the correct monitor resolution. I have a 34" ultra widescreen monitor. Only one monitor connected. It detects the correct resolution on first boot. The correct monitor resolution disappears after it updates. The correct resolution is 3440x1440, 21:9. The Parallels Tools updates and the monitor resolution is correct until Linux updates again. I have this problem both with Ubuntu and Debian on my M1 Mac.
