The MDP2VGAMM15B active Mini DisplayPort to VGA converter cable lets you connect your Mini DisplayPort-equipped desktop or laptop directly to a VGA monitor or projector at a longer distance than a standard-length cable would support, while saving the expense of additional adapters. The adapter cable is compatible with Intel Thunderbolt, when connected directly to a supporting DisplayPort over Thunderbolt I/O port. Plus, because the converter cable supports video resolutions up to 1920x1200 you can convert a DisplayPort video source to VGA without sacrificing video quality. The MDP2VGAMM15B is backed by a 2-year StarTech.com warranty and free lifetime technical support.
