[QUOTE="harryb2448, post: 1649571, member: 42497"] Power off, remove the second monitor, unplug everything from mains for ten minutes or so. Boot up and see what happens. If only the grey screen again, try power down using the on/off button and restart. If you means the iMac monitor does not work, that may be the end of things for the iMac alas. Keep us posted?
