Extended Display Identification Data (Edid) - TANDBERG 770 MXP User Manual

6.13 Extended Display Identification
Data (EDID)
Extended Display Identification Data (EDID) is a VESA standard data format that will allow the
system to communicate its capabilities, including vendor information like the supported VGA-
formats and frequency range limits to a PC connected to the XGA/DVI input.
Note that this requires a system supplied with a XGA/DVI input.
This means that the PC always* will be able to output a valid VGA/DVI signal to the system with
no manual reconfiguration of the PC screen settings.
TANDBERG supports EDID structure v1.3, which adheres to the MS Plug & Play definition.
This standard contains information on product ID, basic display parameters, timing identifications
and detailed timing descriptions.
In F1 and above, TANDBERG will use the EDID information to decide which resolution to use,
800x600 @ 75Hz or 1024x768 @ 60Hz.
Example (1024x768@60Hz)
