LCD Monitor Quality
and Pixel Policy
The 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 LCD. 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 display does not have 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)
defective pixels.
