The Mini DisplayPort® to DVI adapter, model MDP2DVI3, allows you to connect a video source (like any of your MacBook® or Microsoft® Surface ™ Pro devices equipped with Mini DisplayPort) with a monitor, projector or DVI screen, which avoids the need from having to upgrade your monitor to one compatible with Mini DisplayPort.
Compatible with Intel® Thunderbolt ™ when connected directly to a DisplayPort I / O port via Thunderbolt, the adapter supports on-screen or projector resolutions up to 1920×1200 (WUXGA) and conforms to HDCP standards.
MDP2DVI3 is a passive adapter that requires a DP ++ port (DisplayPort ++), which means that DVI and HDMI signals can also be transferred through the port.
