 read-edid (read EDID information from a video monitor)
 
-read-edid is a pair of tools (originally by John Fremlin) for reading the
-EDID from a monitor. It should work with most monitors made since 1996
-(except for newer ones with 256-byte EDID's - WiP), assuming the video
-card supports the standard read commands (most do).read-edid is a set
-of two tools - get-edid, which gets the raw edid information from the
-monitor, and parse-edid, which turns the raw binary information into an
-XF86Config-compatible monitor section.

+
+Modern Linux kernels also make the EDID data available in
+/sys/class/drm/card*-*/edid, so the get-edid command might not be needed.
+
+See also system/edid-decode, which gives more detail than parse-edid,
+but doesn't format its output as an xorg.conf-compatible snippet.
