My Samsung ATIV Book 9 Plus has a HD 4400 graphics unit and runs fine at 3200 x 1800, so you shouldn't have to worry unless you're doing something pretty graphically intensive.

Same here. I run graphical software like Office and Photoshop on my 3200x1800 ATIV Book 9 Plus and haven't noticed any performance issues.
