screen resolution is limited by how much pixel there is on the screen on an LCD screen or by the Horizontal and Vertical specific refresh rate limit on cathodic tube monitor.
But it's also possible on some graphics card to have a bigger resolution and needing to scroll the screen with the mouse to see more, but you can't see your whole screen at once.
And not many screen will handle it, it's more than HD btw, because HD is 1024x768 HDMI is higher so maybe SuperHD is the term?
My screen max resolution is 1680x1050 ):
My max graphic card resolution is 2048x1536 though
The few that will be able to play this game will probably like it, alot
