LCD Monitor Quality and Pixel Policy for f70 Monitor

f70 17-inch monitor

The HP f70 TFT monitor uses high-precision technology, manufactured according to HP 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 D5064 displays. 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 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 D5064 display does not have more than:

•15 total dot defects.

•10 defective full pixels.

•10 defective red sub-pixels.

•4 defective green sub-pixels (green is most visible).

•10 defective blue sub-pixels.

•No more than two adjacent (less than 2.5 mm edge-to-edge) and 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 and 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 displays with fewer cosmetic imperfections and HP will adjust guidelines as improvements are made.
