What does this mean? I'm a fairly retarded cs player and don't know alot about computers. On the box of the cable it says DVI-D, i guess the D in the end might stand for dual.
Edit, this is not the cable the monitor came with, but it's identical to that one. Could this make a difference if i switch them out?
DVI-D is a form of DVI that only carries a digital signal compared to DVI-I which carries both a digital and Analog signal -- DVI-I can be converted to VGA while DVI-D can NOT.
The XL2420Z should have come with a dual link DVI cable though as my XL2411Z came with one. (A dual link DVI cable says "Dual Link" on the connector)
Use the DVI cable that came with the monitor.
