EDID
Extended Display Identification Data
Parameter data transmitted by a display device to a signal source over the DDC channel, describing the supported resolutions, refresh rates, color depths, and other capabilities of the display. The source device uses this information to output a format optimally compatible with the connected display.
Many RGBlink video processors and videowall controllers have EDID management capibilities to make available additional or custom resolutions from a connected source.
