Decode EDID data in human-readable format
edid-decode decodes EDID monitor description data in human-readable format. If [in] is not given, or [in] is '-', then the EDID will be read from standard input. If [out] is given then the EDID that was read from [in] is written to [out] or to standard output if [out] is '-'. By default the output is written as a hex dump when writing to standard output or a raw EDID if written to a file.
How to use it
To decode an EDID from a file run
edid-decode-snap.edid-decode <file-name>
for example, if you have saved the EDID data of your Aquos display in a file named sharp-aquos-hdmi, you can decode it by
edid-decode-snap.edid-decode sharp-aquos-hdmi
