Ubuntu – RPi 4B Ubuntu 19.10 Resolution problem

display-resolution

I just got a Raspberry Pi 4 model B with 4 GB of Ram. I installed ubuntu 19.10 server for RPi and xubuntu-desktop. The problem is that I have it connected with a 4K TV and the resolution is 1892×984 and it cannot change. Can anyone help?

  • After installing Ubuntu 19.10, I had a similar problem connecting the Raspberry Pi 4 model to a 4k computer monitor. Adding the following lines to /boot/firmware/usercfg.txt solved it for me:

    disable_overscan=1
    hdmi_force_hotplug=1
    hdmi_enable_4kp60=1
    

    If this doesn't help, there is a lot of information on the Raspberry Pi github site, e.g. you can find information about video options at https://github.com/raspberrypi/documentation/blob/master/configuration/config-txt/video.md
