I have a Dell desktop PC, and whenever I choose anything other than an 8-bit 640x480 display, the monitor goes off.
What could be causing this? The monitor has been used previously on this PC before, but it was taken to PC World (UK) to have Windows re-imaged onto it.
Could this be a hardware failure (graphics card, cable, monitor) or is it likely to be software/Windows configuration problem?
What things would you check?
It seems that this is linked to the graphics "hardware acceleration" in Graphics Options > Troubleshooting. Turning this down to zero means the machine opens and I can get to the desktop.
