So i was looking around and noticed that one of my monitors is connected with a HDMI cable, and the other with a VGA cable and i'm almost certain that since the other one is connected with the VGA i don't get the full HD usage out of it ( may be wrong though ) and i have 3 ports the VGA port, DP port & the HDMI port, so i was wondering is the DP port HD? or something i've never really seen it and i checked at the back of my monitors and none of them seem to support the DP port, can i simply get an adapter DP to HDMI? or can i swap the ports over is it an easy process if i just open up the computer? ( very noobish btw i've only looked in my computer a few times to put ram sticks in etc. )
any suggestions or help much appreciated.
