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?
Just some questions (since I do not run multimonitor) Have you tried making the second monitor the primary display? If so ... does it show the higher resolutions? Have you tried JUST the second monitor? Does it then show the higher resolutions?
