180 Say Y here, if you want to use EDID data to be loaded from the
181 /lib/firmware directory or one of the provided built-in
182 data sets. This may be necessary, if the graphics adapter or
183 monitor are unable to provide appropriate EDID data. Since this
184 feature is provided as a workaround for broken hardware, the
185 default case is N. Details and instructions how to build your own
186 EDID data are given in Documentation/admin-guide/edid.rst.
