    Unknown Display in Xubuntu 21.04 server on RaspberryPi 4

    I have Xubuntu desktop installed on the Ubuntu Server on my RPi4 (2gb ram.) When it boots the video resolution is set to 640x480 and indicates that I have an unknown display. I have the Pi connected to a 27" Dynex TV that acts as my monitor for several PC's.

    I cannot find where to change the video settings so that I can get higher resolution.

    Can anyone point me in the right direction.
