Reduced image quality when using scaled resolution on Ubuntu 14.04.

I am on a Dell Precision 7710 with a Quadro M4000M video card and Ubuntu 14.04 with the Nvidia 352.63 driver. When I open Nvidia X-Settings and look at my resolution settings, I can only select between ‘auto’, ‘3840x2160’ (i.e. native), and a number of lower resolutions with a ‘scaled’ qualifier. I would like to use a lower resolution (1920x1080) that matches a pair of external monitors I am connected to. When using a scaled resolution, however, the display image becomes blurry. I’m wondering if this is a result of the screen resolution scaling.


  1. Is there a way to select non-native resolutions in X-settings without the ‘scaling’ qualifier?
  2. If not, is there a way to address a blurry display while using a scaled resolution?
  3. The 352.63 driver was the recommended driver for my system, but is there a better one I could be using?
