"The MDP2DVIMM3B Mini DisplayPort to DVI Adapter Cable lets you directly connect your Mini DP video source (Desktop PC, Laptop, Ultrabook™, etc.) to a DVI monitor or projector, eliminating the expense of having to upgrade to a Mini DisplayPort-capable monitor. The adapter cable is 3 feet (1 m) in length, and features male-to-male connectors, allowing you to connect your Mini DisplayPort source directly to a DVI display device with no additional cabling required. Compatible with Intel® Thunderbolt™, when connected directly to a supporting DisplayPort over Thunderbolt I/O port, the adapter supports resolutions up to 1920x1200 (WUXGA). MDP2DVIMM3B is a passive adapter that requires a dual-mode DisplayPort port (DisplayPort++), meaning that DVI and HDMI signals can also be passed through the port. Backed by a StarTech.com 2-year warranty and free lifetime technical support."
