The only choice I have for screen resolution is 1824 X 984 (9:5) I know that my monitor will do 1920 X 1080 (16:9)
I installed Ubuntu Server 20.04 and then installed the Ubuntu desktop. should we not have more choices for our monitor resolution? Raspberry Pi 4 8 GB.

I have Ubuntu 20.04 64bit rpi4 8Gb, ubuntu dektop,
2 24" monitor in simple HD
this is my /boot/firmware/usercfg.txt:
dtparam=spi=off
dtoverlay=vc4-fkms-v3d
hdmi_drive:0=1
hdmi_group:0=2
hdmi_mode:0=82
hdmi_force_hotplug=1
hdmi_drive:1=1
hdmi_group:1=2
hdmi_mode:1=82
the :0 and :1 are ti address monitor.
after this the monitor are detected well
The networkManager and wifi make me crazy but this is a different story.
I had this simular problem aswell and I found a post for 19.04 on rpi here([). you need to modify the file /boot/firmware/usercfg.txt and add the following lines:
disable_overscan=1
hdmi_force_hotplug=1
hdmi_enable_4kp60=1
hope this helps and good luck.
