Hey there.. I posted a while back because I was having issues with an HD5770.. I since got my self a Palit GT630 which had VGA port on it so all problems gone. One day however, out of boredom I decided to put my DVI-I -VGA adapter into it, low and behold.. No signal.. Now I have 3 cards that have the exact same DVI-I ports but only the GT7600 works and I have a lovely working HD5770 with only DVI-I and HDMI ports .. I know I am going to need a new screen but I just dont understand how the DVI-VGA adapter works with one card but not the others that also have DVI-I.. Its really frustrating. Does anyone know why this might be at all?.
