Under normal circumstances, an audio/video source device (digital or analog) will require information about a connected device/display to assess what resolutions and features (capabilities) are possible. The source device can then tailor its output to create resolutions and/or features that are compatible with the attached device/display. This capability information is called EDID (Extended Display Identi ...
