.SH NAME
|
|
i-nex-edid - Decode EDID data in human-readable format
|
|
.SH SYNOPSIS
|
|
.B i-nex-edid [in] [out]
|
|
.SH DESCRIPTION
|
|
.B i-nex-edid
|
|
decodes EDID monitor description data in human-readable format. It takes
|
|
zero, one, or two arguments. If invoked with no arguments it reads from
|
|
standard input and writes to standard output. With one argument, the file
|
|
named by the argument is read instead. With two arguments, normal output
|
|
is suppressed, and the binary EDID blob is written to the file named by
|
|
the second argument.
|
|
.PP
|
|
Input files may be raw binaries or ASCII text. ASCII input is scanned for
|
|
hex dumps; heuristics are included to search for hexdumps in
|
|
.B xrandr(1)
|
|
property output and
|
|
.B Xorg(1)
|
|
log file formats, otherwise the data is treated as a raw hexdump. EDID blocks
|
|
for connected monitors can be found in
|
|
.B /sys/class/drm/*/edid
|
|
on modern Linux systems with kernel modesetting support.

|
.SH NOTES
|
|
Not all fields are decoded, or decoded completely. Some fields' decoding
|
|
may appear to corrupt the output (for example, detailed string sections
|
|
have their contents printed literally).
|
|
.B i-nex-edid
|
|
does attempt to validate its input against the relevant standards, but its
|
|
opinions have not been double-checked with the relevant standards bodies,
|
|
so they may be wrong. Do not rely on the output format, as it will likely
|
|
change in future versions of the tool as additional fields and extensions are
|
|
added.
