A broken wire or a loose connection in the video cable can do that. There are three wires which are grounded or connected with diodes that identify Macintosh monitors. They are checked at power-on time. If they were loose when last powered up the monitor type will appear frozen. Reseat the cable, make sure the screws are tight then shut down all the way to power-off. Restart. -- --> From the U S of A, the only socialist country that refuses to admit it. <--
