Save the EDID. Now easier to use with external controls.
Computers can sometimes lose the EDID basically the electronic identification of a display which lists its possible resolutions and frequencies. When displays are switched away or disconnected and then reconnected, the EDID can be lost and the computer can lose the ability to display the image properly.

The DVI Detective solves this problem by memorizing the EDID information. It does this by being programmed in a simple process. Once the DVI Detective has the display's EDID memorized, it can be placed over the output of the computer's video port, where it fools the computer into thinking that a display is present, even when the display is switched away to another computer.
