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