We prefer to use DVI-D Copper Cables which are designed to carry digital-only signals between the graphics card and the digital video display. If you are trying to connect two digital-only devices, you should use DVI-D cables.
We prefer DVI-D cables that are configured for dual link operation which feature a full set of pins for increased bandwidth. We also look for cables with thicker, 24-gauge wires which allow for super high resolution. Most consumer-grade cables only feature thinner, 28-guage wire which limits systems to lower resolutions and transmission distances of less than 5 meters.
