+                       Broken monitors, graphic adapters and KVMs may
+                       send no or incorrect EDID data sets. This parameter
+                       allows to specify an EDID data set in the
+                       /lib/firmware directory that is used instead.
+                       Generic built-in EDID data sets are used, if one of
+                       edid/1024x768.bin, edid/1280x1024.bin,
+                       edid/1680x1050.bin, or edid/1920x1080.bin is given
+                       and no file with the same name exists. Details and
+                       instructions how to build your own EDID data are
+                       available in Documentation/EDID/HOWTO.txt. An EDID
+                       data set will only be used for a particular connector,
+                       if its name and a colon are prepended to the EDID
+                       name.
