Connect a legacy HD video device or your computer's video and audio output to an HDMIequipped HDTV using this DVI Video + Digital Coaxial and Digital Optical Audio to HDMI Converter from Monoprice! Before the nearly universal adoption of HDMI; many HD devices were released with a DVI video output. Additionally; many computer video cards are equipped with DVI outputs; instead of HDMI. This adapter allows you to combine the video signal from a DVI video source with either a Digital Coaxial or Digital Optical Audio output into an HDMI audio/video signal for use with an HDTV or HDMIequipped AV receiver.
