LCD Monitor Quality and Pixel Policy
for f2304 Monitor
The HP f2304 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 f2304 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 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:
■ 5 total defects — combination of full pixel and sub-pixel
defects
■ 3 defective bright sub-pixels
■ 5 defective dark sub-pixels
■ Bright dots must have a 15 mm minimum separation
■ Bright dot to dim dot must have a 5 mm minimum
separation
■ Dim dot to dim dot must have 5 mm minimum separation
