and/or mechanical hazards.
Read and follow these instructions
when connecting and using your
computer monitor.
Operation
• Please Keep the monitor out of
direct sunlight, very strong bright
lights and away from any other heat
source. Lengthy exposure to this
type of environment may result in
discoloration and damage to the
monitor.
• Remove any object that could fall
into ventilation holes or prevent
proper cooling of the monitor’s
electronics.
• Do not block the ventilation holes
on the cabinet.
• When positioning the monitor, make
sure the power plug and outlet are
easily accessible.
• If turning off the monitor by
detaching the power cable or DC
power cord, wait for 6 seconds
before attaching the power cable
or DC power cord for normal
operation.
• Please use approved power cord
provided by Philips at all times. If
your power cord is missing, please
contact your local service center.
(Please refer to Customer Care
Consumer Information Center)
• Do not subject the monitor to
severe vibration or high impact
conditions during operation.
• Do not knock or drop the monitor
during operation or transportation.
Maintenance
• To protect your monitor from
possible damage, do not put
excessive pressure on the LCD
panel. When moving your monitor,
grasp the frame to lift; do not lift
the monitor by placing your hand or
fingers on the LCD panel.
• Unplug the monitor if you are not
going to use it for an extensive
period of time.

clean it with a slightly damp cloth.
The screen may be wiped with a
dry cloth when the power is off.
However, never use organic solvent,
such as, alcohol, or ammonia-based
liquids to clean your monitor.

1. Important
• If foreign substance or water gets in
your monitor, please turn the power
off immediately and disconnect
the power cord. Then, remove the
foreign substance or water, and
send it to the maintenance center.
• Do not store or use the monitor in
locations exposed to heat, direct
sunlight or extreme cold.
• In order to maintain the best
performance of your monitor and
use it for a longer lifetime, please
use the monitor in a location
that falls within the following
temperature and humidity ranges.
• Temperature: 0-40°C 32-104°F
• Humidity: 20-80% RH
Important information for Burn-in/
Ghost image
• Always activate a moving screen
saver program when you leave
your monitor unattended. Always
activate a periodic screen refresh
application if your monitor will
display unchanging static content.
Uninterrupted display of still or
static images over an extended
period may cause “burn in”, also
known as “after-imaging” or “ghost
imaging”, on your screen.
• “Burn-in”, “after-imaging”, or
“ghost imaging” is a well-known
phenomenon in LCD panel
technology. In most cases, the
“burned in” or “after-imaging” or
“ghost imaging” will disappear
gradually over a period of time after
the power has been switched off.
Warning
Failure to activate a screen saver, or
a periodic screen refresh application
may result in severe “burn-in” or “after-
image” or “ghost image” symptoms
that will not disappear and cannot be
repaired. The damage mentioned above
is not covered under your warranty.
Service
• The casing cover should be opened
only by qualified service personnel.
• If there is any need for any
document for repair or integration,
please contact with your local
service center. (please refer to the
chapter of “Consumer Information
Center”)
• For transportation information,
please refer to “Technical
Specifications”.
• Do not leave your monitor in a car/
trunk under direct sun light.
Note
Consult a service technician if the
monitor does not operate normally, or
you are not sure what procedure to take
when the operating instructions given
in this manual have been followed.

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 flat 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 different types of
pixel defects and defines 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.

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 different 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)

6. Customer care and warranty
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.
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 '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.

6. Customer care and warranty
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.
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. 1 or 2 adjacent sub pixel defects = 1 dot defect
2. This monitor is ISO9241-307 compliant(ISO9241-307: Ergonomic requirement ,
analysis and compliance test methods for electronic visual displays)
3. ISO9241-307 is the successor of formerly known ISO13406 standard, which is
