Pros: This adapter does not have a DVI-D Dual Link connector as advertised. Instead it has a *DVI-I" Dual Link connector. The difference is the four extra pins around the offset ground bar that you can actually see in the large picture. These four pins prevent it from being used with most monitors. The offset ground bar is also different size. See below.

Cons: from the cablestogo.com web site "This connector appears almost identical to the dual-link DVI-D connector except that it has an additional four pins that surround the flat offset ground bar. This is because the DVI-I interface was designed to carry both digital and analog signals. However, most DVI displays and video sources are DVI-D, and the female ports do not contain sockets to accept the four extra analog pins. As a result, DVI-I cables are limited to a narrow range of applications such as certain KVM switches. Also note that the offset ground bar on a DVI-I plug is larger than the one on a DVI-D plug. This means that a DVI-I connector cannot fit into a DVI-D socket simply by removing the four analog pins."
