Computers and other high definition video source devices can sometimes lose the EDID (extended display identification data), when switched away from the source. When displays are switched off, EDID can also be lost, and a computer or high definition video device may no longer be able to show the video properly. The Gefen DisplayPort Detective Plus provides rapid integration of your source and display by allowing the EDID to be pre-set or recorded. This data is then stored in non-volatile memory. The display can then be switched or relocated to a different source, providing the source with the correct display setting. External DIP switches allow pass-through or blocking of HDCP and DPCP based on your application, and provide instant access to other pre-programmed EDID banks.
