You might have then to create an xorg.conf (or better a xorg.conf.d/)
There  are  ways  to create your own EDID-file, but I have never tried
that.  Instead for my monitor with corrupted EDID I tell the driver to
ignore it and have grabbed the modelines from Xorg.0.log.
Generally you do that with 'Option "IgnoreEDID"' in the device section
or 'Option "UseEDID" "Off"' in the monitor section.
With nvidia you use something like:
Option "ConnectedMonitor" "CRT-0, DFP-0"
Option "UseDisplayDevice" "CRT-0"
Where  CRT  is ananog (also when through DVI-I with converter) and DFP
digital  (HDMI  or  DVI-D).  It's  all  described extensively in their
documentation.
