The DVI-D and Stereo Audio to HDMI Converter is the perfect solution for connecting a source with a DVI-D video and a Stereo Audio output to a single HDMI input on a display. Most displays will not support a separate audio input when the HDMI input is used. This product provides a solution to that problem by allowing DVI-D video and Stereo Audio to be combined into a single signal that is sent over an HDMI cable to the display. The DVI-D and Stereo Audio to HDMI Converter extends the useable life of equipment by allowing a legacy source device to be connected to a new display. Note: This converter is not designed to support analog signals and should only be used with a source device which produces a digital video output. This device is not capable of connecting a VGA source device to and HDMI display.
