Extend a DVI-D port by 6in, to prevent unnecessary strain on the port. The DVIDEXTAA6IN 6-inch DVI-D Port Saver Cable/coupler avoids expensive repairs to a computer or display. It does this by extending the port by 6in, 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.
