About EDID
Extended display identification data (EDID) is data provided by a
video display device (usually a monitor) to describe its
capabilities to a video source. The video source uses the EDID to
determine the capabilities of the monitor and, therefore, to
determine the resolution, color depth and other settings that the
monitor will accept.
EDID is defined by a standard published by the Video Electronics
Standards Association (VESA). The EDID includes manufacturer
name, product type, phosphor or filter type, timings supported
by the display device, display size, luminance data and (for
digital displays only) pixel mapping data. EDID is crucial for DVI
sources but mostly ignored by VGA sources.
When you connect an Epiphan Frame Grabber to a video source,
the video source sees the Frame Grabber as a monitor. Just like a
monitor, the Frame Grabber contains EDID that is used by the
video source to determine the video signal to send to the Frame
Grabber.
