You are going to have to tell us more about you setup.

For example what is the make and model of the monitor ??

There are several places you can look:

  1. uEnv.txt
  2. Stop u-boot at the command prompt and do a printenv
  3. Use a console debug cable and look at the cmdline displayed
  4. If you don’t have a console debug cable, do a dmesg after to login and look for cmdline. I expect this to be the same as /proc/cmdline
    Usually the video setting are set in uEnv.txt file. You probably want something like this:
    kms_force_mode=video=HDMI-A-1:640x480@60

You should also see $(kms_force_mode) in one of the bootargs lines.

This is a good resource for all Beaglebone related.

my first link on the specs for that state it is a VGA monitor so you are using some HDMI to VGA converter and there lies the problem.
