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

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 solvent, such as, alcohol, or ammonia-based 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 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

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

21.5″ 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 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 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)

Meridian 3

12

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. 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 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.

compliance test methods for electronic visual displays)
