Review on StarTech.Com Dual Link DVI Cable - 25 Ft - Male To Male - 2560X1600 - DVI-D Cable - Computer Monitor Cable - DVI Cord - Video Cable (DVIDDMM25) by Reynaldo Guzman

A lot of people don't understand "dual link". As a result they might find that a digital KVM they bought doesn't work properly. Switch manufacturers don't tell you that if you have a monitor with 1920 x 1200 or higher display, a single link just doesn't allow the bandwidth necessary to operate the switch properly. My IOGEAR double KVM works perfectly now since I purchased this cable. Great, clear display quality and quick computer switching is the result of the correct cables. These are true dual link cables and connectors at a good price.
