NAME¶edid-decode - Decode EDID data in human-readable format
SYNOPSIS¶edid-decode [in] [out]
DESCRIPTION¶edid-decode 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.
Input files may be raw binaries or ASCII text. ASCII input is scanned for hex dumps; heuristics are included to search for hexdumps in xrandr(1) property output and Xorg(1) log file formats, otherwise the data is treated as a raw hexdump. EDID blocks for connected monitors can be found in /sys/class/drm/*/edid on modern Linux systems with kernel modesetting support.
