EDID DIP SWITCH GUIDELINES
Extended display identification data (EDID) is a data structure provided by
a display to describe its capabilities to any source that asks for it. The EDID
includes manufacturer name, product type, timings supported by the display,
display size, luminance data, (for digital displays only) pixel mapping data,
supported audio channels and formats. This information is used by the source
to cater its output to resolutions and audio formats that are supported by the
display.
Additional EDID modes are available and configured using a combination of dip
switches 1, 2, and 5. Please refer below for the different EDID modes.
To access the Dip Switches, remove all screws from the bottom and sides of the
Gefen unit. Remove the hex screw heads from each side of the RS-232 port and
above each HDMI connector. Carefully slide the unit apart. The 8 Bank of Dip
Switches are located on the main PCB. Once adjustments are complete, slide
the unit back together and replace all removed screws.
