hello, i bought the hd 7700 using vga connections. okay so in order for me to get a display when i every i start my computer. i have to un plug and then plug back in the dvi in the back of my computer. i have been doing this for months now idk if there a problem with the card or computer. i am using a vga converter into a dvi. should i not be doing this will it harm my card please tell me thank you.
It could very well be the converter that's to blame. Ideally you should avoid using them. The adapter won't damage anything, but at the very least you should use a standard VGA cable without an adapter if that's possible, if only to confirm that the adapter is the culprit.
Generally speaking, as regards graphics and colour quality on-screen, DVI offers no discernible ddifference over VGA. Certainly I could see no difference between the two that would compel me to use DVI.
