Troubleshooting and Maintenance Getting Assistance for Your Notebook If the screen is difficult to read • Try setting the display resolution to its default setting of 1024×768: click Start, Control Panel, Appearance and Themes, Display, Settings. • Try adjusting the size of the desktop icons and labels-see "To adjust the display" on page 35. 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 35. 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 you're using a TV connected to the S-video port, you must activate the TV-see "To use a TV set as a monitor" on page 85. • Test the display with the e-Diagtools diagnostics-see "Testing the Hardware" on page 119. If one or more display pixels look bad 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. HP notebook TFT displays meet or exceed all HP standards for cosmetic quality of TFT displays. HP does not warrant that the displays will be free of cosmetic imperfections. TFT displays can have a small number of cosmetic imperfections and still conform to HP's cosmetic quality specifications, including the following: • No more than 6 pixels remain on (always one color, such as white, red, green, or blue dots). • No more than 6 pixels remain off (always dark). • No more than a total of 8 pixels stuck on or off. • No other stuck pixel within 15 mm of a stuck pixel. 102 Reference Guide
