The Gefen HDMI to DVI with Audio converter is a specialized interface device designed to split and convert a single HDMI signal into separate DVI video and analog audio outputs. This addresses a common connectivity challenge where a source device with an HDMI output, such as a modern Blu-ray player, gaming console, or set-top box, needs to connect to an older display or monitor that only has a DVI input for video and requires separate left/right audio inputs. The DVI standard carries only digital video, so this device extracts the digital audio embedded within the HDMI stream, converts it to analog, and outputs it simultaneously with the DVI video, ensuring both picture and sound are delivered to the target system.

The converter operates as an active device, requiring external power to process the high-bandwidth digital signal and perform the necessary digital-to-analog conversion for the audio. It supports high-definition video resolutions up to 1080p (1920x1080) and maintains support for HDCP content protection, allowing for the legal playback of encrypted commercial content. The unit handles the EDID communication between the source and the display, ensuring proper resolution negotiation, and typically features a straightforward plug-and-play design with no user configuration required, making it accessible for both home theater enthusiasts and professional installers.

Housed in a compact casing, this converter is a practical and cost-effective solution for integrating new HDMI sources into legacy DVI-based presentation or display systems without sacrificing audio capability. It eliminates the need for a separate audio extractor and provides a clean, integrated conversion in a single package. By bridging the gap between the all-in-one HDMI interface and the video-only DVI interface, it effectively extends the useful life of high-quality DVI monitors and projectors in the face of evolving source technology, providing a reliable and high-fidelity connection path.
