The MDP2DVIS Mini DisplayPort to DVI adaptor (single-link) lets you connect your Mini-DisplayPort video source (PC, laptop, MacBook, etc.) to a DVI-D display, including televisions and Apple Cinema Display HD, eliminating the expense of having to upgrade to a DisplayPort capable monitor. Unlike passive video adaptors, this Mini DisplayPort to DVI adapter offers an active conversion for use with any Mini DisplayPort output - ideal for graphics cards that are not capable of outputting multi-mode DP++ signals (e.g. ATI Eyefinity). Supporting resolutions up to 1920x1200, this compact device provides a simple solution for adapting PC or Mac Mini-DisplayPort output for compatibility with existing DVI monitors, televisions or projectors. Compatible with Intel Thunderbolt, when connected directly to a supporting DisplayPort over Thunderbolt I/O port. Backed by a StarTech.com 1-year warranty and free lifetime technical support.
