  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.
