Choosing a DVI cable can be a tricky. Among the many differences in DVI cables are whether they are single link or dual link. Even jumping in from there, the patterns of connectors are different with dual link possibly being DVI-I or DVI-D, and single link potentially being DVI-A, DVI-I, or DVI-D. Keeping all these things in mind, let’s start with the basics on DVI cables.

There’s dual link and single link. Dual link are designed to double the power of transmission, and provide an increase in speed and signal quality over single link. Many of today’s high resolution monitors depend on dual link cables to do their jobs.

As mentioned above, the DVI types spread across single link and dual link connections are DVI-D, DVI-I, and DVI-A. The most popular of these three are DVI-D, which features high resolutions, strong bandwidth, and is the best choice for a digital display. Comparatively, DVI-I is largely designed to maximize signal quality going from digital to analog or vice versa. Meanwhile, DVI-A is strictly used for analog signals. Therefore, as someone setting up a contemporary home entertainment setup or who is using a laptop, they will likely want a dual link connector and always a DVI-D cable.
