GF-EDD-HD – HDMI EDID Detective

HDMI EDID Detective for Signal Stability and Performance

The HDMI EDID Detective from Gefen is a professional tool designed to eliminate EDID-related issues in HDMI signal chains. By capturing and storing Extended Display Identification Data (EDID), this device ensures stable communication between HDMI sources and displays—even if the display is powered off, disconnected, or replaced. Ideal for AV professionals and system integrators, it helps maintain consistent output in high-performance environments.

Maintain HDMI Sync with Confidence

Whether you’re working in broadcast, digital signage, education, or enterprise systems, HDMI sync issues can derail performance. The Gefen HDMI EDID Detective solves this by storing EDID locally and feeding it back to the source, preventing signal dropouts and resolution mismatches. Supporting resolutions up to 8K60 and 4K120 with full HDMI 2.1 compliance, it guarantees optimal signal integrity across demanding AV installations.

Robust Features and Advanced Format Support

This HDMI EDID emulator is engineered for versatility. It supports modern video formats like Dolby Vision™, HDR10+, and HLG, and enables VRR, ALLM, QMS, QFT, and SBTM passthrough—delivering immersive video quality. Six factory-set EDID profiles and six customizable slots allow precise configuration for different setups. You can manage EDID profiles and firmware through the USB-C port using Gefen’s Syner-G™ software. DIP switches provide additional control over HDCP modes and EDID behavior.

Audio Compatibility and Signal Integrity

Beyond video, this HDMI signal stabilizer supports LPCM 7.1, Dolby Atmos®, DTS:X™, and other multichannel audio formats. It ensures seamless transmission of both audio and video, even in the most complex installations. DDC re-clocking improves HDCP handshake reliability, reducing errors during playback or device switching. The active HPD feature keeps the source connected, maintaining communication through power cycles and cable changes.
