Display Problems

If the computer is on, but the screen is blank
• Move the mouse or pointing stick. This will wake the display if it is off.
• Press Fn+F5 in case the internal display was disabled. (Do this three times to return to
the state you started from.)
• If the computer is cold, allow it to warm up.
If the screen is difficult to read
• Try setting the display resolution to its default setting of 1024×768: click Start,
Settings, Control Panel, Display, Settings.
If an external display does not work
• Check the connections.
• Press Fn+F5 in case the external monitor was disabled. (Do this three times to return
to the state you started from.)
• The external monitor may not be detected. In the BIOS Setup utility, try setting Video
Display Device to Both in the Main menu.
• If you're using a TV connected to the S-video port on an expansion base, you must
activate the TV—see "To use a TV set as a monitor" on page 83.
• Test the display with the e-DiagTools diagnostics— see "Testing the Hardware" on
page 162.
If an external display cannot use high resolutions
• For Windows 98, use the default display type for the internal display: Default
Monitor. If you change the display type, non-Plug-and-Play (non-DDC) external
monitors will not be able to use resolutions higher than the resolution of the internal
display. You can check display settings using Display in Control Panel, or by right-
clicking the desktop and then clicking Properties.
