LCD Monitor Quality and Pixel Policy
Your LCD Monitor uses high-precision technology, manufactured according to high standards, to
help guarantee trouble-free performance. Nevertheless, the display might have cosmetic
imperfections that appear as small bright or dark spots. This is common to all LCD displays that
are used in products supplied by all vendors and is not specific to your 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. 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 subpixel (dot defect) is less visible
than a defective whole pixel, and is small and only visible on a specific background.
To locate defective pixels, the monitor must 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).
