I was using my desktop computer connected to a 19" flat screen monitor for the last 6 mths i have had the desktop connected to my 42" tv and was using that as my computer screen through the VGA port, I have connected it back up to my original 19" monitor and when you switch the monitor on all it says on the screen is a box floating around a black screen saying no data supported I have asked a few friends and they are saying that it something to do with the graphics properties or something but i am not sure how to correct this my graphics card is a Nvidia 8400gs I have plugged the monitor into a friends desktop to check that it is still working and it works fine, can someone please help as i am at wit's end with and i am sure there is a simple solution.
Thanks in advance
Pete
