If the system is new, and you're within the return period, you'll need to arrange a return and purchase a more capable notebook (5000 series or better, XPS, etc.). This one is limited to FHD resolution over HDMI. [URL]  
Hi Dears, I've just start using my new 15 3000 (i15-3501-A70S) with NVIDIA MC 330 inside.  I have a ultrawide monitor tha supports 2560x1080 resolution (LG 29WK600). How can I get higher resolution from this notebook? The max hdmi is 1920x1080... is it possible to improve it? how? Best regards.
