DIP SWITCH GUIDELINES
DIP SWITCH
EDID GUIDE
Extended display identifi cation 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 confi gured 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 rear DVI port. 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.
