High Definition displays with HDMI inputs use EDID (Extended Display Identification Data) to ensure that a connected Hi-Def source sends compatible audio and video signals. In some scenarios, this data can be lost, resulting in an incorrect signal or complete loss of audio and/or video. The Gefen HDMI EDID Detective Plus has been designed specifically to address this issue by recording the display EDID date and making it available to the Hi-Def source reliably and on a continuous basis. With DDC re-clocking technology, the reliability of HDCP handshaking is improved, ensuring that the Hi-Def source always receives the correct EDID. Using the Gefen EDID Tool+ PC software or terminal emulation via USB, the installer can also manipulate/modify the EDID data to meet installation-specific requirements and resolve system-specific compatibility issues. The HDMI EDID Detective Plus has been designed for quick and easy programming and installation.
