Transmit EDID Continously

This product has been replaced by the Gefen DVI Detective N.

The DVI Detective 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 DVI Detective 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 DVI Detective, 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. The Detective 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).

What is EDID?
EDID - Extended Display Identification Data is a VESA standard data format that contains basic information about a monitor and its capabilities, including vendor information, maximum image size, color characteristics, factory pre-set timings, frequency range limits, and character strings for the monitor name and serial number.

How It Works

Connect the source on one side of the DVI Detective and the extension module or switcher on the other side.

Note:  Now supports full 256 byte EDID.
