I've been using a second monitor for a while, and it's usually alright, but this time when I unticked "extend my windows desktop onto this monitor" for what I think was the second monitor, they both went blank. Now when I start up my computer everything starts up fine, except the monitor is black and I can't see anything on the screen.
I'm in safe mode now, but it's forcing me into 600x800 res and theres no options for dual monitor setups on the context menu properties thing.
This happened yesterday too and I just waited and it worked again this morning as if nothing had happened, but then I screwed it up again. I've tried plugging in the second monitor, leaving it off, but still nothing.
