Connect an HDMI monitor to a Single Mode Display Port Video Source. The DP2HDSW Active Display Port to HDMI Adapter features audio pass-through support, which enables you to connect both the audio & video that''s output from a Display Port-equipped desktop or laptop computer to an HDMI monitor, projector, or display. Unlike a passive adapter, the DP2HDS actively converts single-mode & dual mode Display Port output, which is ideal for graphics cards that do not output dual mode/multi-mode (DP++) signals, such as ATI Eyefinity cards. This active DP to HDMI adapter is compatible with Intel Thunderbolt, when connected directly to a supporting Display Port over Thunderbol I/O port.
