About: Gefen 1:2 HDMI Splitter with Digital Audio

The 1:2 Splitter for HDMI 1.3 with Digital Audio sends a Hi-Def A/V source to up to 2 HDTV displays at the same time without losing quality or resolution. This product works with any Hi-Def source supporting resolutions up to 1080p Full HD with Deep Color, 3DTV pass-through, and lossless audio formats such as Dolby TrueHD and DTS-HD Master Audio. A TOSLINK output on the rear of the Splitter feeds digital audio to an external amplifier or receiver for additional installation flexibility.

How It Works
