The monitor is a Samsung GH22WS Widescreen LCD 216BW 21 inch. It has digital and analog inputs and I've been using the digital. Cable has a DVI connector on the monitor end going to HDMI on the computer end.

I'm working away, minding my own business and suddenly the display has gone. Once it came back. I've seen that kind of crash and recovery with NVIDIA drivers but this is using the latest Microsoft driver.

Where would I look for what caused it?

Thanks - rev
