You have the following possibilities:

1) Get a valid EDID file for your monitor and pass it to the driver as described in Appendix B of the nvidia Readme

2) Overwrite the EDID data with manual specified values (resolutions, frequencies, dpi) and by disabling edid based modes. You find the options needed for that as well in the Appendix B of the readme.

Kind regards

That makes a lot of sense. I took a look at the appendix mentioned and it seems pretty daunting. However, I'll see if I can figure out which settings to alter and let you know what happens.
