Hi,
Using x11-drivers/nvidia-drivers-355.11 breaks my setup. under Gentoo Linux.
Primary monitor is an HP w2207h (1680x1050)
Secondary Monitor is an Pavilion 22xi (1920x1080)
Staring KDE with the mentioned nvidia driver, the display on the primary monitor is shown wrong. I have a black border on the left which is about 1/6 of the screen (it looks squeezed).
The primary display is distorted, secondary is displayed fine.
Checking under X Server Display Configuration with nvidia-settings shows the correct values (1680x1050) and (1920x1080).
GFX Card is a GeForce GTX 660
cat xorg.conf

Switching back to x11-drivers/nvidia-drivers-352.41 solves the problem.
