Got a strange issue with Display Resolutions from my Nvidia GTX GeForce 550 Ti.
I am using the current "Proprietry, Tested" Nvidia driver in the Additional Drivers section, however it is only allowing me to see two resolutions 1024x768 and another much higher one that makes the text really small. I have used xrandr and the other file in /etc/X11 to manually add new resolutions, however when switched to these resolutions my display produces a blank screen and says "Mode Not Supported", I would be happy to accept that my screen cannot display these resolutions, however I am using the same card and machine as a dual boot to Windows 8 and that can handle 1600x900 and many other resolutions fine.
Is there something specific with Ubuntu and Nvidia that produced a weird signal that my display cannot handle, but Windows does fine??
