The display controller also controls the video mode, which uses industry standard rules to govern the screen resolution and the maximum number of colors that can be displayed on screen.
Software written for a given video mode will run on any computer that supports the mode.
The computer's display controller supports all VGA modes, the most widely used industry standards.
Some of display modes might not be supported depending on the external monitor which you use.
