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 o riginal invoice or cash receipt, indicatin g the date of p urchase,
dealers name and model and production number of the product.

Warnings

Use of controls, adjustments or procedures other than those specified in this document ation 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

y Keep the monitor out of direct sunlight and away from stoves or any other heat source.
y Remove any object that could fall into ventilation holes or prevent proper cooling of the monitor’s electronics.
y Do not block the ventilation holes on the cabinet.
y When positioning the monitor , make sure the power plug and outlet are easily accessible.
y 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.

y 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)

y • Do not subject the monitor to severe vibration or high impact conditions during operation.
y • Do not knock or drop the monitor during operation or transportation.

Maintenance

y 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.

y Unplug the monitor if you are not going to use it for an extensive period of time.
y 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 sol vent, such as, alcoh ol, or ammonia-ba sed liquids to clean
your monitor.

y 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.

y If your monitor gets wet, wipe it with dry cloth as soon as possible.
y 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.

y Do not store or use the monitor in locations exposed to heat, direct sunlight or extreme cold.
y 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.

¾ Temperature: 0-40°C 32-95°F
¾ Humidity: 20-80% RH

y IMPORTANT: 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 a s
“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 bee n switched off.

Warning

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

y The casing cover should be opened only by qualified service personnel.
y 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")

y For transportation information, please refer to "Technical Specifications".
y 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.

4.3 Pixel Defect Policy

Philips strives to deliver the highest quality products.
We use some of the industry’s most advanced
manufacturing process and practice stringent quality
control. However, pixel or sub pixel defects on the TFT
LCD panels used in flat panel monitors are sometimes
unavoidable. No manufacturer can guarantee that
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
LCD panel must exceed these acceptable levels. For
example, no more than 0.0004% of the sub pixels on a

21.5Ǝ XGA monitor may be defective. Furthermore,
Philips sets even higher quality standard 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 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
signal black pixel. Other combinations of lit and dark
sub 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 pixel s
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 three
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)

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.

!

!

Meridian 3

14

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. There are
two 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 LCD p anel in
a Philips flat panel monitor must have pixel or sub pixel
defects exceeding the tolerances listed in the followin g
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 re quirement, analysis and compliance test
methods for electronic visual displays)
