I have installed the arm64 (aarch64) image on a raspberrypi 3b+. My problem is that I cannot change the screen resolution to something sensible. My monitor is an HP LA2405wg and I am attaching it through HDMI. By default the resolution is 656x416. There are no other options available in the Display > Monitor Preferences menu. I have tried changing some options in the
config.txt file but I couldn't make it work. I am trying to find the correct options through the
tvservice command as mentioned in this article. I see from this forum post that another user was able to use tvservice command. However I am getting:
$ tvservice -s tvservice: command not found
Why would this be happening?
P.S. I tried to fix the problem by enabling some
config.txt options such as
hdmi_force_hotplug=1 but I couldn't make it work.
