Ubuntu – Cant get HD resolution working on second monitor, nvidia GT640 card, Ubuntu 14.04

Got a working screen via HDMI, but the DVI won't go past 1360×768 (a PackardBell Maestro monitor). Had no issues in Windows 7.

I've tried all the xrandr tricks, see the output below:

I'm using the latest driver from Nvidia (binary, 352.63) because Nouveau would show a black screen on my second monitor.

I got stuck on manually finding/creating a xorg.conf file and adding some monitor hacks, can anyone help me?
