3.4 AMD FreeSync™ Premium Pro
PC gaming has long been an imperfect
experience because GPUs and monitors
update at dierent rates. Sometimes
a GPU can render many new pictures
during a single update of the monitor,
and the monitor will show pieces of each
picture as a single image. This is called
“tearing.” Gamers can x tearing with
a feature called “v-sync,” but the image
can become jerky as the GPU waits on
the monitor to call for an update before
delivering new pictures.
The responsiveness of mouse input and
overall frames per second are reduced
with v-sync, too. AMD FreeSync
TM
Premium Pro technology eliminates all
of these problems by letting the GPU
update the monitor the moment a new
picture is ready, leaving gamers with
unbelievably smooth, responsive, tearing-
free games.

8. Customer care and
warranty
8.1 Philips’ Flat Panel Monitors
Pixel Defect Policy
Philips strives to deliver the highest
quality products. We use some of the
industry's most advanced manufacturing
processes and practice stringent quality
control. However, pixel or sub pixel
defects on the TFT Monitor panels used
in at panel monitors are sometimes
unavoidable. No manufacturer can
guarantee that all panels will be
free from pixel defects, but Philips
guarantees that any monitor with an
unacceptable number of defects will be
repaired or replaced under warranty.
This notice explains the dierent types
of pixel defects and denes acceptable
defect levels for each type. In order to
qualify for repair or replacement under
warranty, the number of pixel defects on
a TFT Monitor panel must exceed these
acceptable levels. For example, no more
than 0.0004% of the sub pixels on a
monitor may be defective. Furthermore,
Philips sets even higher quality standards
for certain types or combinations of pixel
defects that are more noticeable than
others. This policy is valid worldwide.
Sub pixels
Pixels
Pixels and Sub pixels
A pixel, or picture element, is composed
of three sub pixels in the primary colors
of red, green and blue. Many pixels
together form an image. When all sub
pixels of a pixel are lit, the three colored
sub pixels together appear as a single
white pixel. When all are dark, the three
colored sub pixels together appear as a
single black pixel. Other combinations of
lit and dark sub pixels appear as single
pixels of other colors.
Types of Pixel Defects
Pixel and sub pixel defects appear on the
screen in dierent ways. There are two
categories of pixel defects and several
types of sub pixel defects within each
category.
Bright Dot Defects
Bright dot defects appear as pixels or sub
pixels that are always lit or 'on'. That is, a
bright dot is a sub-pixel that stands out
on the screen when the monitor displays
a dark pattern. There are the types of
bright dot defects.
One lit red, green or blue sub pixel.
Two adjacent lit sub pixels:
- Red + Blue = Purple
- Red + Green = Yellow
- Green + Blue = Cyan (Light Blue)

30
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 species tolerances for the proximity
of pixel defects.
Three adjacent lit sub pixels (one white
pixel).
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 'o'. 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.

31
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 at panel monitor must have pixel or sub pixel
defects exceeding the tolerances listed in the following tables.
BRIGHT DOT DEFECTS ACCEPTABLE LEVEL
1 lit subpixel 3
2 adjacent lit subpixels 1
3 adjacent lit subpixels (one white pixel) 0
Distance between two bright dot defects* >15mm
Total bright dot defects of all types 3
BLACK DOT DEFECTS ACCEPTABLE LEVEL
1 dark subpixel 5 or fewer
2 adjacent dark subpixels 2 or fewer
3 adjacent dark subpixels 0
Distance between two black dot defects* >15mm
Total black dot defects of all types 5 or fewer
TOTAL DOT DEFECTS ACCEPTABLE LEVEL
Total bright or black dot defects of all types 5 or fewer
Note
1 or 2 adjacent sub pixel defects = 1 dot defect
