Looks like your monitor simply has wrong EDID values in it.  The nvidia
driver is ignoring what the monitor says its capable of and firing
things up at 50Hz.  It appears to believe your monitor's firmware was
encoded incorrectly.

So, seems to be more of a hardware bug than nvidia or X.  From the logs
look like software is compensating for the hardware problem.  Other than
the unexpected refresh rate value setting are you noticing any visible
issues?  If not, we can probably close this as 'not a software bug'.
