Good quality, DVI-D (Dual Link) extension cable

The cable is well made, has thumbscrews on both plugs. Faults I could not tell. The short extension cable is used as an adapter to connect a fully wired DVI-I (Dual Link) cable using an adapter to onboard graphics cards.
Onboard graphics cards usually feature DVI-D connectors (24 + 1 pin), thus DVI-I cable can not be connected without an adapter. But as with the computer adapter is back to spreading, there the cable as an intermediate piece. Can be so especially reposition easier.
