You should not detect any difference. HOWEVER if you try to play BluRay on VGA you discover or learn about HDCP which is not possible on VGA.
i just wanted opinions as to the benefits of dvi over vga. we have a 27" dell monitor that's hooked up with vga and frankly,,,it looks great. but i'm thinking of getting another 27"monitor that has vga connector only, so i was thinking am i depriving myself in case i should ever prefer a dvi connection.
and is the difference noticeable or is this something that can only be detected in a side by side comparison.
