Defining EDID

The Extended Display Identification Data (EDID
provided by a display, to describe its capabilities to an HDMI source. The
EDID enables the VS-81H to "know" what kind of monitor is connected to
the output. The EDID includes the manufacturer's name, the product type,
the timing data supported by the display, the display size, luminance data
and (for digital displays only) the pixel mapping data.
