whats the point of having them on a monitor? whats are benefits? pros/cons.
What, do you really get confused that easily
No, but the way you worded it made it seem like you had no clue as to what they do.
DVI is just digital, and there are no clear advantages over VGA.
HDMI is in the same boat, but if you have built in speakers on the monitor, you don't have to use a separate audio cord to use them.
BTW, you could have just used Google to find out.
