DVI Detective Plus


Save the EDID -- for HDTV equipment as well as Computers.

The Gefen DVI Detective Plus solves issues related to EDID that prevent signal passing from source to display in HDCP-enabled systems. EDID stands for Extended Display Identification Data. It is the standard table of characteristics of a display that is used by the source to optimize its output resolution, timing, and other operating parameters. When a display is switched off, de-selected by a matrix/switcher, or disconnected and then reconnected, the EDID can be lost. If this occurs, the video source device may lose its ability to output the correct image instantly. The Gefen DVI Detective Plus addresses this issue by recording the EDID from a display and making it available to a source at all times, as if the display is still connected. This product also passes through the communications between an HDCP-enabled source and display as necessary.
