Manually changing resolution does not result any improvement. System (stable branch) is up to date. I didn't try to downgrade packages. Want to avoid it at all - also for tuture.

Seeing something similar (likeky) on the VGA output since the 355 driver. DVI is not affected, but VGA only fills like 4:3 on a 16:10 screen.
The resolution (1440x900) is ok and so is the monitor. Also (and that may be a difference?) if I pass the screen a 4:3 resolution (XGA) the monitor stretches it (by setting) across the entire panel.
=> I suspect a bug in the nvidia driver, affecting the analog output.

Something similar happening here. I have ugly fonts, the content of the screen is squeezed (narrower), and there black buffers around the desktop. That happens only after I startx (gtx 960). ttys have full screen resolution. It started to happen sometime ago. In xubuntu, it doesn't happen, but it is an older nvidia driver.
There is a difference between knowing the path and walking the path.

I finally updated my system and got this issue too. Any driver version >=353 causes this for me, so I made some AUR packages that install the latest 352 drivers (352.63 at the current time).
Look for nvidia-352, nvidia-utils-352, nvidia-libgl-352 and opencl-nvidia-352 in AUR. I'll maintain them until NVIDIA fixes their crap.

@drewwalton19216801 Thanks. I am trying to install these (which are the versions ubuntu 15.10 currently provides by default) but I am getting problems with dependencies.
Anyway, I plugged a different (and bigger monitor) and the problem simply disappeared. It seems for some reason the nvidia driver is just not handling "this" monitor correctly. Perhaps there is a setting I can force on nvidia/xorg for this particular monitor. I'll try to figure out.
EDIT: By the way, when I look at xfce display config, I see resolution: 1360x768, refresh rate: 60. It is the same both in arch and xubuntu. Just that the newer driver is not working properly (perhaps with some monitors only, not all, idk.)
