Philips 7FF1CWO - Manual (Page 41)

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:
One dark sub pixel Two or three adjacent dark sub pixels
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.
