Force the capture card to use a specific 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 (usually a graphics or video output card in a PC or another device).
The video source uses the EDID to determine the capabilities of the monitor to determine the resolution, color
depth and other settings that the monitor can support.
EDID is crucial for DVI sources but mostly ignored by VGA sources.
Like monitors, each video capture card in Pearl contains an EDID. When you connect a VGA or DVI video
source (such as a laptop or video camera), this source sees Pearl's capture card as a monitor and uses its EDID
to negotiate which video signal to send.
Generally capture card's DVI input correctly emulates a monitor that supports your video source. However
sometimes, particularly if your source uses a custom set of display properties, you need to help Pearl by
uploading a custom EDID to force the capture card to report that it emulates a resolution, color depth, etc
needed by your laptop, camera or other video source.
