+                        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.
