+			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.
