Extended display identification data (EDID) is a set of data that
is provided by a display to describe its capabilities to a graphics
adapter. EDID data allows a computer to detect the type of monitor
that is connected to it. EDID data includes the manufacturer name,
the product type, the timings that are supported by the display, the
display size, as well as other display characteristics. EDID is
defined by a standard published by the Video Electronics Standards
Association (VESA).
In Windows, every display device has an associated 'EDID' registry
key containing this data. Applications can read and parse it to get
the display capabilities. In Linux, we can get each monitor's EDID
using the RANDR X extension.
This patch fixes, for example, monitor detection in the UE-based game
'Industries of Titan'.
