LCD Monitor Quality and
Pixel Policy
The HP vf52 TFT monitor uses high-precision
technology, manufactured according to HP
standards, to guarantee trouble-free performance.
Nevertheless, the monitor may have cosmetic
imperfections that appear as small bright or dark
spots. This is common to all LCD monitors used in
products supplied by all vendors and is not specific
to the HP vf52 monitors. 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 vf52 monitor does not have more than:
•
5 total dot defects.
•
Zero defective full pixels.
•
3 bright sub-pixels (red, green or blue; always on).
•
5 dark sub-pixels (red, green or blue; always off).
•
No more than two adjacent (less than 2.5 mm
edge-to-edge) 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, 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 LCD monitors with
fewer cosmetic imperfections and HP will adjust
guidelines as improvements are made.
