Thanks. It looks like comment #10 is correct. Also the kernel is correctly reporting that the laptop display is OFF and the external monitor is ON. So I think Plymouth should be enhanced to check that and not bother with outputs that are OFF. Then it would only be driving one monitor and the minimum resolution would be the correct resolution = 1920x1200.
