LCD Monitor Quality and Pixel Policy
The FP9419 LCD Monitor uses high-precision technology,
manufactured according to high 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 FP9419 LCD Monitor. 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 FP9419 LCD Monitor has:
Less than 5 total dot defects
0 defective full pixels
3 defective bright sub-pixels (maximum)
5 defective dark sub-pixels (maximum)
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.).
We expect that, over time, the industry will continue to improve its
ability to produce displays with fewer cosmetic imperfections and
we will adjust guidelines as improvements are made.
