Dual DVI-I to a Dual DVI-D, what's the difference?


I'm planning to purchase a 144hz monitor from Asus VG278H and a XFX HD 7970. I've noticed that the card has a Dual DVI-I but the monitor has a Dual DVI-D port. I want to know if I can still get a 144hz refresh rate? and if not, what should I do to be able to get 144hz refresh rate?

  1. One post per topic please


    Asus makes this 144 Mhz model - ASUS VG248QE. The VG278H is a 120 Mhz model

    Either way, the VG278H comes with nVidia 3D glasses which will be useless w/ your chosen GFX card.

    DVI-D is digital only
    DVI-I is digital + analog

    You need a dual link DVI cable to run 120 / 144 Mhz


    I'd strongly suggest a nVidia GTX 670 for both those monitors.
  2. Sorry for that, kinda new in forums, won't happen again.

    It seems I linked the wrong monitor, Asus VG278HE, so just to be sure, as long its a Dual Link DVI cable, regardless if its a Dual Link DVI-I or Dual Link DVI-D, it will work fine, and I will still be able to get a 144hz, right? If I choose to go with the Asus VG278H, why will it be useless?
