Solving Problems with Your Computer
Troubleshooting Techniques
Reference Guide 105
If the screen is difficult to read
• Check whether the display resolution is set to its default setting—1024×768 for 13",
14", and 15" TFT displays: click Start, Settings, Control Panel, double-click Display,
then click Settings (Windows 98 or 2000), or click Start, Control Panel, Appearance
and Themes, Display, Settings (Windows XP).
• Try adjusting the size of the desktop icons and labels—see “To adjust the display” on
page 33.
If part of the Windows desktop is not visible and you have to scroll down to see the
taskbar, or does not fill the entire display and has a black border
• Your display resolution may be set incorrectly. Adjust the resolution as needed—see
“To adjust the display” on page 33.
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.)
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.
If one or more pixels look bad on a TFT display
TFT display manufacturing is a highly precise but imperfect technology, and
manufacturers cannot produce displays that are cosmetically perfect. Most, if not all, TFT
displays exhibit some level of cosmetic imperfection. These cosmetic imperfections may
be visible under varying display conditions, and can appear as bright, dim, or dark spots.
This issue is common across all vendors supplying TFT displays in their products and is
not specific to the HP notebook display.
