I am using for a the Slick2d engine for my game that is supposed to run in fullscreen. On Windows, everything is fine, the rather low resulution of 1024x768 is scaled the (mostly higher) resolutions of the monitors. On Mac however it seems to be unable for me to achieve the same result, depending on the DisplayMode/ resolution that is chosen, the graphics are either stretching over the monitors boundaries or the whole game is displayed unscaled in the left-upper corner of the screen. It gets worse when a second monitor is connected, because it seems that Mac assume the fullscreen as a combination of both screens.
Does anyone know how I can configure the displaymode so that one monitor scales the game to fully fit the space?
