Technical Specifications LCD Monitor Quality and Pixel Policy The HP LCD Monitor uses high-precision technology, manufactured according to high standards, to guarantee trouble-free performance. Nevertheless, the display may have cosmetic imperfections that appear as small bright or dark spots. This is common to all LCD displays used in products supplied by all vendors and is not specific to the HP LCD Monitor. These imperfections are caused by one or more defective pixels or subpixels. ■ A pixel consists of one red, one green, and one blue subpixel. ■ A defective whole pixel is always turned on (a bright spot on a dark background), or it is always off (a dark spot on a bright background). The first is the more visible of the two. ■ A defective subpixel (dot defect) is less visible than a defective whole pixel, and is small and only visible on a specific background. The HP LCD Monitor has: ■ Less than 5 total dot defects ■ 0 defective full pixels ■ 3 defective bright subpixels (maximum) ■ 5 defective dark subpixels (maximum) To locate defective pixels, the monitor should be viewed under normal operating conditions and in normal operating mode at a supported resolution and refresh rate, from a distance of approximately 50 cm (16 inches). We expect that, over time, the industry will continue to improve its ability to produce displays with fewer cosmetic imperfections, and we will adjust guidelines as improvements are made.
