Product Information and Troubleshooting Important display information All HP notebook display panels adhere to strict quality and reliability specifications. A small percentage of display panels may have minor cosmetic imperfections that appear as bright or dark dots (described below) in the viewable area: ✎ This is consistent with industry standards and common to all display panel types used by notebook PC vendors and is not specific to any HP model or product line. ■ A pixel consists of 1 red, 1 green, and 1 blue subpixel, each of which is commonly referred to as a dot. ■ A pixel imperfection may manifest as either always turned on (a bright spot on a dark background), or as always off (a dark spot on a bright background). ■ A subpixel imperfection is less visible than a whole pixel imperfection since it is small and may be visible only on a specific background. HP expects that, over time, the industry will continue to improve its ability to produce displays with fewer cosmetic imperfections, and HP will adjust guidelines as improvements are made.
