Does the integrated graphics (AMD Radeon 7 Series 200) support resolution of 2500 x 1440 or only 1920 x 1080? I have a HP550-027C computer. It appears that my max resolution is 1920 x 1080 according to the display interface on Windows 8.1. Before returning the computer, I want to make sure I am not missing anything as to the max resolution. I am running a Dell U2711 monitor which has the capability of a higher resolution than 1920 x 1080.
