Hi, sorry to bother with this dumb question. So I have just receive a 512 MB card from my friend and it has a DVI (White input) and a VGA (Blue input) and I was wondering, which input should I choose? I tried using both input and it does work but I need to enable two monitor in my Windows 7 settings to use. And I only got one better. So I'm asking, which input should I use to get a better result? The DVI or VGA? Please help and sorry for the bother.
