SINGLE-LINK OR DUAL-LINK THAT IS THE QUESTION!
The DVI-D and DVI-I formats (described below) are available in either Single or Dual link formats. Dual-Link cables are backward compatible with Single-Link cables and allow you to achieve very high resolutions if your video card and LCD support it. The general rule of thumb is that single link cables are good to 1920 x 1080, while dual link cables can achieve a resolution of 2048 x 1536. So, check your LCD specs, if it says single link, then there is no point in getting a dual link cable (not quite true, since you can use a dual link cable later if you upgrade your LCD). The price difference between a single link an dual link cable is usually only a few bucks.
