LCD Monitor Quality and Pixel Policy
Your Hewlett-Packard TFT display uses high precision technology,
manufactured according to HP standards, to guarantee trouble-free
personal computing. Nevertheless, your 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 D5062A 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.
Defective sub-pixels are less visible than defective whole pixels.
Defective sub-pixels are small and only visible on a specific
background.
Defective means either the pixel or sub-pixel is stuck always ON, a
bright spot on a dark background, or it is stuck always OFF, a dark
spot on a bright background. The first is the more visible of the two.
A dot defect is a stuck sub-pixel.
Your HP D5062A will not have more than:
• 10 total dot defects
• 8 stuck full pixels
• 8 stuck red sub-pixels
5 stuck green sub-pixels (green is most visible)
•
• 8 stuck blue sub-pixels
• No more than two adjacent pixels may be stuck
Adjacent is defined as less than 15mm edge to edge
No more than two pairs of two-adjacent stuck pixels per display.
•
To locate defective pixels, the unit should be viewed under normal
operating conditions and in normal operating mode at a supported
resolution and refresh rate, from a distance of approximately 50cm
(16 in.).
HP expects that over time, the industry will continue to improve its
ability to produce displays with fewer cosmetic imperfections and HP
will adjust our guidelines as improvements are made.
