The MDP2DVIS Mini DisplayPort to DVI Active Adapter (single-link) lets you connect your Mini-DisplayPort video source 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 adapters, 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 DVI monitors, televisions or projectors.
The Mini DP to DVI adapter is compatible with Intel Thunderbolt, when connected directly to a supporting DisplayPort over Thunderbolt I/O port.
