The HDMI EDID Detective Plus from Gefen keeps HDMI sources and displays in sync. This device has been designed specifically to ensure that a connected high-definition source sends compatible audio and video signals without losing the EDID (Extended Display Identification Data). This is done by recording the HDMI display EDID and making it available to the high definition source reliably and on a continuous basis.With DDC re-clocking technology, the reliability of HDCP handshaking is improved, ensuring that the high definition 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 device has been designed for quick and easy programming and installation.
