   That suggests the problem is that the monitor claims it can do such-and-such   
   resolution, and then isn't happy when the Pi does it.  Do you have a menu   
   button on the monitor you can press and does it tell you the resolution, or   
   does it say 'no signal' or 'out of range' or something?   
      
   I'd guess the solution is to configure the desktop environment to use a   
   different resolution, but it will depend on the DE as to how you configure   
   that from the command line without using the DE's settings UI (which you   
   can't see).   
      
   You could also try xrandr after setting a $DISPLAY variable, something like:   
      
   $ export DISPLAY=:0   
   $ xrandr --mode 640x480   
      
   which should temporarily set the resolution to 640x480.  Then you can get   
   into the settings UI.   
      
   Note this is for X11 - I'm not sure what the equivalent is for Wayland.
