EDID Setup
EDID (Extended Display Identification Data) is a data structure provided by a digital display to
describe its capabilities to a video source. This data is also known as a “handshake” and typically
includes manufacturer, serial number, product type, resolutions supported by the display, display
size, pixel mapping data, etc.
Key Digital EDID Control allows the integrator to choose the handshake that will be provided to
source devices of the system. The EDID handshake is relayed to the source from the Champion
Series switch, not from any of the displays/output devices of the system. This handshake will
always be the EDID information that the source device receives.
To change the EDID of the system, press the following buttons on the Key Digital IR Remote
control: R2 » R1 » R3 » XX.
The XX characters will be replaced with the two digit number that corresponds to the EDID you
wish to set. Use the below chart to find the various EDID settings. The default EDID is ‘00’--Copy
EDID from output 1.
The possible EDID settings can range from ‘00’ to ‘12’. (‘00’ is the default).
00 Copy EDID from HDMI Output 1 07 3D, 2Ch Audio
01 1080i, 2Ch Audio 08 3D, Dolby/DTS 5.1
02 1080i, Dolby/DTS 5.1 09 3D, HD Audio
