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.
