I have a video editing PC with GTX 470 graphics card.
About once a week, without warning, the screen goes black. I get the small alert bottom right saying "DVI" first, then "no signal".
I've checked the connections but nothing restores the video signal other than a force restart, which W7 complains about and I hate doing.
The HDMI socket from the card goes to a projector that has never gone blank, but is rarely turned on. The monitor (Prolite E2710HDS) is connected to one of the DVI ports and is regarded by the PC as monitor 2. It lists it as a projector but this is actually the wrong way round. I don't know how to change the way the PC lists the projector and monitor, but didn't think it mattered.
I have Display Switch constantly set to "Duplicate".
