Just purchased the IBM P260 22" CRT monitor (great monitor btw)...it has dual inputs, standard VGA and DVI-A. My video card is the ATI AIW Radeon which also has DVI-I output...my question is should I go out and by an DVI cable or should I just stay with standard VGA? Is the improvement significant? Also what cable should I purchase? Don't know much about DVI but my understanding is that not all cable work with all DVI outputs/inputs. Any advice would be appreciated.
