3.1 Defining the EDID
The EDID (Extended Display Identification Data
3
) is a data-structure,
provided by a display, to describe its capabilities to an HDMI source. The
EDID enables the
VS-44HDMI
to “know” what kind of monitor is
connected to the output. The EDID includes the name of the manufacturer,
the product type, the timing data supported by the display, the display size,
luminance data and (for digital displays only) the pixel mapping data.
