Save the DisplayPort EDID from the display to the source
Computers and other Hi-Def video source devices can sometimes lose the EDID (Extended Display Identification Data), when switched away from the source. When displays are switched off (or disconnected and reconnected), EDID can also be lost and a computer or a Hi-Def video device may no longer be able to show the video properly. The Gefen DisplayPort Detective Plus allows an EDID to be pre-set or recorded from a display. The data is then stored in non-volatile memory. The display can then be switched or relocated to a different source, providing the new source with the correct video. External DIP switches can provide instant access to pre-programmed EDID banks, providing rapid integration of your source and display.
How It Works
Connect a DisplayPort cable from the display to the output port of the DisplayPort Detective Plus. To copy the EDID from the display, connect the included 5V DC power supply or a powered USB port to the DisplayPort Detective Plus. Press and hold the Program button on the front panel to record the EDID of the connected display. Remove the power supply and connect the source to the input port using the included DisplayPort cable.
Note: The 5V power supply is needed only to record the display EDID. For normal operation, leave the power supply disconnected.
