    I have a Ubuntu VM install with 1024x768 with no options for higher resolution. The Mac 4k Monitor resolution 3840x2160 is set for 2560x1440 and I would like the set Ubuntu to 1600x900. I have tried xrandr procedures which do not work.

    Same issue, ran some experiments
    TL;DR i can see all resolutions and control it from Ubuntu settings>Displays only if Parallel guest tools are NOT installed!!

    seems like display is controlled by Parallel only after installing guest tools, also i can see that the option "More Space" in vm Graphics settings only give one more big resolution but you don't have all resolutions to choose from like the case before installing Parallel Tools!
    I am using Ubuntu 20.04.02 LTS
    Parallel Desktop Version 16.1.3 (49160)
