    Re: resolution problem

    That usually is caused by your monitor EDID not being read correctly or by your video not being set for resolutions/refresh rates actually supported by your monitor.

    https://wiki.ubuntu.com/X/Config/Resolution is a good wiki for setting your own resolutions.

    In order for more help on actually using xrandr or resolutions which might work, you should list your actual model number of your monitor.

    Re: resolution problem

    According to the user manual on-line, your maximum resolution is 1360x768, with a refresh rate between 60-75 Hz. From your listed options, the 1280x720 is the maximum display size usable (720p) with the given driver settings. You can try setting to 1360x768@60Hz or 1360x768@72Hz, but that may not give you a better display, instead, it may cause similar problems to the ones you are describing.

    Re: resolution problem

    Your nVidia settings tool is probably your best tool to set your resolution. You should be able to use the 1280x720 resolution suggested by the nVidia tools.

    You might also try arandr from the Software Center or simply the Display tool in your systems settings.
