3.1  Defining the EDID 
The Extended Display Identification Data (EDID

 7.2
) is a data-structure 
provided by a display to describe its capabilities to an HDMI source. The 
EDID enables the VS-66H3 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. See Section   for 
details on how to acquire the EDID.
