I am using ElementaryOS on an Acer E5 Laptop with Intel Haswell Graphics and an Nvidia GT840M. The screen of that laptop is 1920x1080 and works fine. At work I connect a second monitor. That one support a resolution of up to 2560x1440. But in the settings it only shows a maximum of 1920x1200. I tried looking in the nvidia x server settings, but there it only shows I have one screen. Does anyone have an idea what I could do to get the native resolution?
