LCD Monitor Quality and Pixel Policy
The HP 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 HP LCD Monitor. These
imperfections are caused by one or more defective pixels or
subpixels.
■ A pixel consists of one red, one green, and one blue subpixel.

background.
The HP LCD Monitor has:
■ Less than 7 total dot defects
■ 0 defective full pixels
■ 3 defective bright subpixels (maximum)
■ 7 defective dark subpixels (maximum)
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 inches).
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.
