I have attached a second monitor to my laptop (DELL 9400 - using a geforce go7900gs) via the VGA cable on the back.
The monitor worked fine for a few days, and then, after I came back from being away away over the weekend, I'm now having trouble with the display on the second monitor (the laptop display works fine). The second monitor will only display the screen for about 1/2 a second, then becomes blank for 5 to 10 seconds before reappearing for another 1/2 second. I don't think that the monitor loses the connection (when it does a box appears on screen saying that the signal has been lost).
I'm 99% sure that the problem is not in the monitor or the cables, as I have attached my 360 to the monitor via the same VGA input as well as a seperate laptop with the same cable and these both function correctly.
I'm guessing that the cables at the back were pulled down somehow and damaged the VGA output on the laptop, and if this is the case, has anyone else had this problem and managed to find a fix?
The laptop also has a DVI output, and I have a DVI - VGA apaptor, but I can't seem to get an image to appear on screen via this route. Is there a video card setting needed to turn the DVI output on?
Thanks for your help
