How It Works

The Gefen GF-EDD-HD HDMI Detective is a plug-and-play solution that ensures reliable communication between your video source and display. Simply connect it between your source (like a computer or media player) and your HDMI cable that runs to the display. The device will then learn and store the display's EDID information, ensuring that the source always receives the correct display parameters, even if the display is powered off, disconnected, or switched to another input. For custom setups, the device can be programmed via its USB-C port, allowing you to load and manage different EDID profiles using factory presets or your own custom configurations. The built-in DIP switches allow for settings configuration and write-protection control directly on the unit, making it perfect for permanent installations where reliability is critical.
