LCD Monitor Quality and Pixel Policy The HP vf52 TFT monitor uses high-precision technology, manufactured according to HP standards, to guarantee trouble-free performance. Nevertheless, the monitor may have cosmetic imperfections that appear as small bright or dark spots. This is common to all LCD monitors used in products supplied by all vendors and is not specific to the HP vf52 monitors. These imperfections are caused by one or more defective pixels or sub-pixels. • A pixel consists of one red, one green, and one blue sub-pixel. • 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 sub-pixel (dot defect) is less visible than a defective whole pixel and is small and only visible on a specific background. The HP vf52 monitor does not have more than: • 5 total dot defects. • Zero defective full pixels. • 3 bright sub-pixels (red, green or blue; always on). • 5 dark sub-pixels (red, green or blue; always off). • No more than two adjacent (less than 2.5 mm edge-to-edge) defective pixels. • No more than two pairs of two adjacent defective pixels. To locate defective pixels, the monitor should be viewed under normal operating conditions, in normal operating mode at a supported resolution and refresh rate, from a distance of approximately 50 cm (16 in.). HP expects that, over time, the industry will continue to improve its ability to produce LCD monitors with fewer cosmetic imperfections and HP will adjust guidelines as improvements are made.
