Use a console debug cable and look at the cmdline displayed 4. If you don¹t 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.
