resolution 2560x1440


I have notebook lenovo u510 with switchable graphics Intel HD4000 and nVidia 625M. I use openSUSE 13.1. I want use external monitor connected by HDMI with maximal resolution 2560 x 1440 px. By this specifications GeForce 625M should support this resolution by digital output (HDMI should be digital). I have install nVidia driver NVIDIA-Linux-x86_64-331.67. How can I finish my setup?

Thanks for help.

Unless you can switch between Intel and Nvidia in the BIOS setup, some Lenovos can do that, you could try this
