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.
