"Very fast shipping. Good job!"


Using a DVI source with an HDMI display has always been difficult because DVI only passes video, and HDMI passes both video and audio. With most DVI to HDMI adapters you can only pass the video, and the HDMI audio channel is left unused.

Gefen bridges this common gap with the Gefen DVI Audio to HDMI Adapter. Connect your digital audio SPDIF - Sony/Philips Digital Interface Format) and your DVI video source to the adapter. The adapter encodes the digital audio into HDMI audio format and combines it with the DVI signal to produce a neat and convenient HDMI audio/video signal that can be used on any HDMI display device.

Set-up is Easy

Simply connect your digital audio device to the Gefen DVI Audio to HDMI adapter using your own SPDIF cable. Connect your DVI source using the included DVI cable. Then, connect your HDMI display to the adapter, and power the adapter on (5V power supply is included). It is that easy. You will enjoy video and audio on your HDMI display from your DVI source in minutes.

Pros: It did what I needed it to do.

Cons: My alternative was to run 125' of stereo cable and possibly an amplifier. This item was a little pricy but worth it.

Are there adaptors for either HDMI to Analog Audio or Component to HDMI?

Answer: Yes - your best bet is the Gefen Component/Audio to HDMI Adapter. That will allow you to connect your component source and audio to a TV, monitor or projector with an available HDMI input.

Is there a TOSLink version of this kind of device?


We do not have a version of this device that will handle a TOSlink signal instead of the digital coaxial. You could use a TOSlink to Digital Coaxial converter to get that TOSlink signal into that unit.
