Troubleshooting Techniques
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.
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.
Contact HP Customer Care if you have a display quality problem and require a more
comprehensive explanation of HP display quality—see "To contact HP for support or
service" on page 110. We expect that over time the industry will continue to produce
displays with fewer inherent cosmetic imperfections, and we will adjust our HP guidelines
as these improvements are implemented.
