I know it sounds dumb, but did you try unplugging the monitor during a shut
down and then connecting it after the machine has booted again. It should be
plug and play. By the way unplugging the power to it for a few minutes
before booting can sometimes help. Finally, the power switch on some is also
a circuit breaker, and simply cycling it may work. Or there may be a reset
button on it.

Good luck.
