If it is a dvi monitor then you would need a dvi cable. VGA monitor would need a VGA cable. HDMI monitor would need a hdmi cable. If it is compatible with both dvi & vga and your video card has a dvi output then dvi is a better quality than vga. You can purchase the cable online at a store like cables2go. Hope this helps & please remember to rate my answer. Thanks.
I was given an NEC MultiSync 1525X 15" LCD monitor. All that came with it is the power cord. What cable do I need to buy to connect it to my computer?
