Video modes

The computer supports video modes defined in the tables below. If your
application offers a selection of mode numbers that do not match the
numbers on the table, select a mode based on mode type, resolution,
character matrix, number of colors and refresh rates. Also, if your software
supports both graphics and text modes, the screen display may appear to
operate faster using a text mode.
