This 6-inch DVI-D Port Saver Cable/coupler avoids expensive repairs to a computer or display, by extending the port by 6-inch, thereby eliminating the weight and stress that would typically be placed on the port by a DVI cable. This is especially useful in an environment where cables are unplugged and re-inserted frequently. This high quality cable features two DVI digital (dual link) connectors (M/F) and is ideal for connecting laptop computers to digital projectors or for connecting other DVI digital devices such as DVI digital flat panel LCD monitors, HDTVs, Blu-Ray players, DVD players and more.
