D L CD Monitor Q ualit y and P ix el P olicy The TFT monitor uses high-precision technology , manufactured according to HP standards, to guarantee trouble-free performance. Ne vertheless, the display may hav e cosmetic imperfections that appear as small bright or dark spots. This is common to all LCD displays us ed in products supplied b y all vendors and is not specif ic to the HP LCD. These imperfections are caused by one or more defecti ve pixels or sub-pix els. ■ A pixel consists of one red, one green, and one blue sub-pixel. ■ A defecti ve whole pix el is always turned on (a bright spot on a dark background), or it is alw ays off (a dark spot on a bright background). The f irst is the more visible of the two. ■ A defecti ve sub-pixel (dot defect) is less visible than a defecti ve whole pixel and is small and only visible on a specif ic background. The HP display does not ha ve more than: ■ 3 bright dots. ■ 5 dark dots. ■ 5 total bright and dark dots. ■ No more than two adjacent (less than 25 mm edge-to-edge) defecti ve pixels. Use r Guide D–1
