Is 1280 x 800 the max resolution of your screen?

Is what I see when I set my screen on 1920 x 1080

That is on 1920 x 1080. In your picture the menu (with the 3 production slots) covers the whole game screen (from friend list to resource bar).
You are not running this game on 1920 x 1080.
Or is windows set to 200%?
I have a feeling that the Windows Scaling option in the "Display Settings" via the desktop is set rather high in the case.
