what is dvi dual link
A dual-link DVI interface sends data over both of the DVI links to the monitor, and this is how higher resolutions are achieved. With dual-link DVI, a resolution of 2048 x 1536 is possible...juicy! Of course, for dual-link to work, the cable, output source and display device must be geared up for it.Some graphics cards will only have a single link DVI transmitter, which leaves you without the ability to run at ultra-high resolutions.f course, for dual-link to work, the cable, output source and display device must be geared up for it.
