Hello. I have a Asus 1215n with ION. I was able to display the image on a TV via HDMI. I did everything according to the guide (http://www.webupd8.org/2012/08/get-h...ptimus-on.html). The maximum screen resolution is only 640x480. I checked it by "optirun nvidia-settings" and "xrandr". What can I do to get a native resolution of 1920x1080.
