Reference Guide
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 call HP for service and
support” on page 83. 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.
If a TV display does not work properly after resuming from standby
•
In the BIOS Setup utility, try setting Video Display Device to Auto in the Main
menu—see “Using the BIOS Setup Utility” on page 74.
If you cannot switch to a TV display by pressing Fn+F5
•
Fn+F5 switches between the internal LCD and an external display connected to the
VGA port only. It does not switch to a TV display connected to the TV output port.
