EDID Mode Selection
1. EXTERNAL MODE:
See page 12 for details on using the External EDID.
2. INTERNAL MODE:
To use this mode, press the EDID button on the rear panel until the front-
panel LED marked “Int” turns bright green. This mode will use a preset
EDID, from the factory, that is stored in the Gefen 2x4 Switcher for HDMI
1.3. This pre-programmed standard EDID data structure is compatible with
most A/V display devices. All resolutions and audio formats specifi ed in
this EDID will be passed to the source device. See the tables below for a
complete listing of the resolutions and audio formats listed in this EDID.
NOTE: All other HDMI devices/displays connected to the output ports MUST
be compatible with at least one resolution/audio format specifi ed in this
EDID. It is recommended to set, on the source device, a common resolution
and audio format shared by all attached devices/displays. This is to ensure a
compatible signal is output to all connected devices/displays.
