Philips 273P3PHES-00 - Manual (Page 37)

Note
A red or blue bright dot must be more than 50
percent brighter than neighboring dots while
a green bright dot is 30 percent brighter than
neighboring dots.
Black Dot Defects
Black dot defects appear as pixels or sub pixels
that are always dark or 'off'. That is, a dark dot is
a sub-pixel that stands out on the screen when
the monitor displays a light pattern. These are
the types of black dot defects.
Proximity of Pixel Defects
Because pixel and sub pixels defects of the
same type that are near to one another may be
more noticeable, Philips also specifies tolerances
for the proximity of pixel defects.
Pixel Defect Tolerances
In order to qualify for repair or replacement
due to pixel defects during the warranty period,
a TFT Monitor panel in a Philips flat panel
monitor must have pixel or sub pixel defects
exceeding the tolerances listed in the following
tables.
