DDC Support

When establishing a VGA connection between a PC or laptop and a display
device, a set of parameters known as EDID is exchanged between them, which
is carried over the DDC channel. In some PC graphic cards and laptops, this
information exchange is essential for proper VGA OUT operation.
3.3

Defining EDID

The Extended Display Identification Data (EDID
provided by a display, to describe its capabilities to a graphics card (that is
connected to the display's source). The EDID enables the PC or laptop 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.
