EDID Control
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 distribution amplifier, or from output/display 1 (default setting).
This handshake will always be the EDID information that the source device receives.
