"Here is why detecting monitor matters: In Ubuntu, the default set in /etc/X11/xorg.conf for the supported refresh rates of the monitor are extremely conservative. This is because some CRT monitors could stop working if you set refresh rates too high.

The solution with an undetected monitor is usually this:
1- Find somewhere the actual supported refresh rates for your monitor
(for example you can find from that page: http://www0.shopping.com/xPF-BenQ-BenQ-19-LCD-T905-TCO99-Monitor-Silver-Black-12ms that the vertical range is 56-76 and the horizontal range is 31-81).
2- Edit the /etc/X11/xorg.conf file in section ""Monitor"" to use those ranges:
Section ""Monitor""

   Identifier ""Monitor0""

   VendorName ""Unknown""

   ModelName ""CRT-0""

   HorizSync 31.0 - 81.0

   VertRefresh 56.0 - 76.0

EndSection
3- Restart X or your computer
4- Run nvidia-settings and the resolution you're looking for should be there."
