    What's the difference between all the DVI cables on the market?

    I see there's ones called M/D/F 2x dvi and all kinds of stuff. whats the difference between all these?

    (Trying to find a cable to use with a mini display port to dvi adapter. to hook up a external monitor.)

    The main difference with DVI is DVI-D and DVI-I. DVI-D carries a digital only signal, whereas DVI-I carries both a digital and an analog signal.

    The DVI-I port and cable will have extra pins that are designed to carry the analog signal (google DVI-D and DVI-I images and you can see the differences) and are capable of being converted using a DVI-I to VGA adapter. The DVI-D, lacking the analog signal, cannot.

    You'll just need a DVI-D cable to use with your adapter.

    Edit: You can use a DVI-D cable with a DVI-I monitor without issues, but if your monitor is DVI-D and your cable is DVI-I the pins will interfere. That's why I suggested a DVI-D cable, and since you won't need the analog signal, that should be okay.
