An EDID (Extended Display Identification Data) is a data structure containing the characteristics and
capabilities of a digital display, such as its graphic card or set-top box.
The EDID of a display is provided by the display itself to the video source, so that the source can identify the
kind of monitor it is connected to.
Different EDID versions exist, but the information contained in the EDID includes:
• Manufacturer name and serial number;
• Product type;
• Phosphor or filter type;
• Timings supported by the display;
• Display size;
• Luminance data and (for digital displays only);
• Pixel mapping data.
13.2 Supported EDIDs
The VIO 4K has been designed to be able to read the EDID version 1.3 and 1.4 from devices connected to the
VIO 4K plugs that support EDID management.
These plugs include:
• DP plugs,
• HDMI plugs,
• Analog plugs,
• DVI-D plugs.
The VIO 4K can then extract the information contained in the read file, and store it in a 256-byte array that
can be retrieved using the Web RCS and the Front Panel interfaces.
The extracted information includes the following data, and it can be used to match the output EDID to the
input EDID:
• Display product name
• Preferred format (used for format autoconfiguration).

NOTE: You can also use the AW EDID Editor for EDID analysis and modification (SEE: AW EDID Editor for more information).
