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. -.PP -.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 edid-decode -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. -.SH "SEE ALSO" -Xorg(1), xrandr(1) -.SH AUTHORS -edid-decode was written by Adam Jackson, with contributions from Eric -Anholt, Damien Lespiau, and others.
