Thats probably it, the message you are seeing is from the VGAs ExpROM,
it is still in text mode, if the monitor is not detected,
the Firmware does not switch to framebuffer mode, thus no output.
Could you try a different monitor?

Yes, if a keyboard is found and no input is found from serial,  the
keyboard is selected as input device... you could detach the keyboard,
and only attach it once linux is up... or press some keys on the
serial console during boot _before_ the keyboard is detected, that
should direct the input to serial.
