Important Safety Notice
This electronic user guide is intended for anyone who uses the Philips monitor. Take time to read this user manual
before you use your monitor. It contains important information and notes regarding operating your monitor. The
Philips guarantee applies provided the product is handled properly for its intended use, in accordance with its
operating instructions and upon presentation of the original invoice or cash receipt, indicating the date of purchase,
dealers name and model and production number of the product.
Warnings
Use of controls, adjustments or procedures other than those specified in this documentation may result in exposure
to shock, electrical hazards 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 and away from stoves or any other heat source.
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 all the time. If your power cord is missing, please contact
with 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.
Unplug the monitor if you need to 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.
To avoid the risk of shock or permanent damage to the set, do not expose the monitor to dust, rain, water, or
excessive moisture environment.
If your monitor gets wet, wipe it with dry cloth as soon as possible.
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.

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 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.

Power Management Definition
If you have VESA DPM compliance display card or
software installed in your PC, the monitor can
automatically reduce its power consumption when not
in use. If an input from a keyboard, mouse or other
input device is detected, the monitor will 'wake up'
automatically. The following table shows the power
consumption and signaling of this automatic power
saving feature:
The following setup is used to measure power
consumption on this monitor.
• Native resolution: 1920 x 1080
• Contrast: 50%
• Brightness: 250 nits or 200 nits
• Color temperature: 6500k with full white pattern

4.3 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
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
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
Two adjacent lit sub pixels:
- Red + Blue = Purple
- Red + Green = Yellow
- Green + Blue = Cyan (Light Blue)
Three adjacent lit sub pixels (one white pixel)
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

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.
Note:
1. 1 or 2 adjacent sub pixel defects = 1 dot defect
2. This monitor is ISO9241-307 compliant Class-I 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 withdrawn by the International
Organisation for Standardisation (ISO) per: 2008-11-13.
