) is a data-structure,
provided by a display, to describe its capabilities to the source. The EDID
enables the
VM-73
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.
