I dont know if ALL VGA adapters work since i havnt looked into it that well since VGA wasnt an option for me.
If i remember right there was a list somewhere on ATI´s website with different adapters that was tested. will see if i can find it
there u got it
Note that this is only the tested ones, that doesnt mean that this is the only ones thats working
A tip would be to just google it and see if u can get a link to a adapter that other people have used and is available in your country.
