Trasmit EDID Continuously

The Gefen DVI Detective (EXT-DVI-EDID) is a unique and useful little device that reads and stores a computer's digital video information (EDID) in order to simplify the installation process for users who are extending a digital projector or plasma display away from the computer.

Once installed and connected, the Gefen DVI Detective (EXT-DVI-EDID) continually transmits the EDID to the computer, essentially "tricking" the computer into thinking that the video is present, even when it is not connected. The user can then disconnect the display, place it in a remote location and reconnect it, without rebooting the operating system. The entire installation process benefits from the Gefen DVI Detective (EXT-DVI-EDID), which utilizes a much smaller cable that requires fewer connections; it makes life easier for those extending digital displays or projectors. An inconspicuous device that weighs less than one pound. Gefen DVI Detective (EXT-DVI-EDID) can connect to and ADC or DVI port with the use of an adapter. It works with all digital displays (DVI) as well as Apple's line of flat panel displays (ADC).
