Channel 1 Default Remote Channel 2 Remote Channel 3 Remote Channel 4 EDID MODES What is EDID and what is it used for Under normal circumstances an audio video source device digital or analog will require information about a connected device display to assess what resolutions and features capabilities are possible The source device can then tailor its output to create resolutions and or features that are compatible with the attached device display This capability information is called EDID Extended Display Identification Data A source device can only accept and read one EDID data structure record from a connected source device display Likewise the source device can output only one video resolution to a connected device display The importance of EDID with regards to the 4x1 DVI DL Switcher The 4x1 DVI DL SL Switcher handles multiple sources inputs Each connected source device must correctly read one EDID data structure in order to address its display device correctly EDID management is carefully handled by the 4x1 DVI DL Switcher to insure that EDID is recorded and retransmitted properly otherwise display of the input sources might not occur correctly or at all Managing EDID with the 4x1 DVI DL Switcher The 4x1 DVI DL Switcher uses 2 modes for routing EDID They are 1 When the local EDID Mode is ON factory default setting the Switcher copies the EDID of the connected display to the local memory loc
