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.
If you are running some applications (for example a 3D application or video
playback and so on), you may see some disturbance, flickering or frame
dropping on your screen. If that occurs, adjust the resolution of display,
lowering it until the screen is displayed properly. You could also disable
Windows Aero™ to help correct this situation.
