D LCD Monitor Quality and Pixel
Policy
The TFT monitor uses high-precision technology, manufactured according to HP standards, to guarantee
trouble-free performance. It is guaranteed to have no bright spots, that is, pixels that are always white.
A pixel consists of one red, one green, and one blue sub-pixel.
If a defective whole pixel is always turned off, it appears as a dark spot on a bright background.
A defective sub-pixel (dot defect) is less visible than a defective whole pixel and is small and only
visible on a specific background.
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
(20 in).
The panel is 90% defect-free at the time of shipment. HP expects that, over time, the industry will
continue to improve its ability to produce LCDs with fewer cosmetic imperfections and HP will adjust
guidelines as improvements are made.
