            Bug ID: 95334
           Summary: GM107 with 2560x1440 display on HDMI selects
                    suboptimal resolution 1920x1080
           Product: xorg
           Version: 7.7 (2012.06)
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
          Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org

Display is a Crossover 2720MDP (cheap South Korean QHD screen). I don't think
this ever worked right with nouveau since when I bought it in March 2013. The
correct full resolution is not available in Ubuntu's System Settings section
'Displays'. It works fine with the nvidia driver (and under Windows). 

$ lspci | grep VGA
01:00.0 VGA compatible controller: NVIDIA Corporation GM107 [GeForce GTX 750
Ti] (rev a2)

Will attach logs later on.
