Am I missing something? All other games which only support lower resolutions than my monitor's native resolution (1080p) can run just fine in "scale to fit".
This for some reason just goes in the middle of the screen with black border all around.

Do you have a Radeon card?

No. A Nvidia 980m.

Oh, in that case I don't think I can help.

Do the driver for the Nvidia 980m have underscan/overscan settings for the display?
