Gefen EXT-DVI-EDIDN DVI EDID Detective/Management

Displays use EDID - Extended Display Identification Data - to communicate to computers the array of video resolutions and timings that they are capable of displaying. In certain situations this data can be lost resulting in incorrect display settings, or even a complete loss of video. The DVI Detective N solves this problem by ensuring that a correct EDID signal is constantly available to the DVI source, even if the display is switched to a different computer. Gefen has designed the DVI Detective N for quick and easy programming and installation. After a simple EDID recording process is completed, the Detective is placed at the DVI output of the computer's video card where it will provide the computer with a constant EDID signal. The DVI Detective N is equipped with DVI ports, but it is also compatible with VGA through the use of optional adapters.
