One of our employee's has dual screen. One of her monitors has suddenly become very dark, you can see windows on it but its too dark to read any text or see where the mouse is. The other monitor is fine.
This happened first a couple of months ago. I thought it was an old monitor problem, switching the monitor seemed to solve it.
Then last week it happened again. I switched the vga cables over to confirm it wasn't the monitor at fault so I changed the graphics card. This again seemed to solve the problem.
Then this morning the employee turned on her pc to find the problem had reappeared. Having replaced the monitor and graphics card already (and drivers since new graphics card required new drivers) I don't know what else it could be.
Not sure if this helps but I did find an error in the system error log for last night...
