So I had my home computer running XP using my Insignia TV as a monitor via VGA cable. I have a windows 7 machine that I would like to replace the XP machine with. The windows 7 machine works fine on my little 19' monitor but when I try to use the TV as a monitor I get a no signal message from the TV as soon as I should get to the log in screen. I have updated my video card drivers (the latest update was less than an month old), and changed my resolution to 1024x768 and still no luck.
