Philips Pixel DefectPolicy
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 LCD panels used in flat panel monitors are sometimes
unavoidable. No manufacturer can guarantee that all panels will be free from pixel
defects, but P hilips guarantees that any monitor with an una cceptable numb er 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 19" XGA 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 th e 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:
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
MODEL220SW8

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:
One dark sub pixelTwo or three adjacent dark sub pixels

General FAQs
Q: When I install my monitor what should I do if the screen shows 'Cannot display this
video mode'?
A:
Q: What does 'refresh rate' mean in connection with an LCD monitor?
A: The refresh rate is of much less relevance for LCD monitors. LCD monitors display a stable,
flicker-free image at 60Hz. There is no visible difference between 85Hz and 60Hz.
Q: What are the .inf and .icm files on the CD-ROM? How do I install the drivers (.inf
and .icm)?
A: These are the driver files for your monitor. Follow the instructions in your user manual to
install the drivers. Your computer may ask you for monitor drivers (.inf and .icm files) or a
driver disk when you first install your monitor. Follow the instructions to insert the ( companion
CD-ROM) included in this package. Monitor drivers (.inf and .icm files) will be installed
automatically.
Q: How do I adjust the resolution?
A: Your video card/graphic driver and monitor together determine the available resolutions.
You can select the desired resolution under Windows® Control Panel with the "Display
properties".
Q: What if I get lost when I am making monitor adjustments?
220SW8 LCD
Recommended video mode for Philips 22": 1680x1050 @60Hz.
1.Unplug all cables, then connect your PC to the monitor that you used
previously.
2.In the Windows Start Menu, select Settings/Control Panel. In the Control
Panel Window, select the Display icon. Inside the Display Control Panel,
select the 'Settings' tab. Under the setting tab, in box labeled 'desktop area',
move the slidebar to 1680x1050 pixels (22").
3. Open 'Advanced Properties' and set the Refresh Rate to 60Hz, then click OK.
4. Restart your computer and repeat step 2 and 3 to verify that your PC is set at
1680x1050@60Hz (22").
5.Shut down your computer, disconnect your old monitor and reconnect your
Philips LCD monitor.
6.Turn on your monitor and then turn on your PC.
FAQs (Frequently Asked Questions)
A: Simply press the OK button, then select 'Reset' to recall all of the original factory settings.
Q: What is the Auto function?
A: The AUTO adjustment key restores the optimal screen position, phase and clock settings
by pressing of a single button – without the need to navigate through OSD (On Screen Display)
menus and control keys.
Note: Auto function is available in selected models only.
Q: My Monitor has no power (Power LED does not light up). What should I do?
A: Make sure the AC power cord is connected between the monitor and AC outlet, and click a
key on keyboard/mouse to wake up the PC.
Q: Will the LCD monitor accept an interlaced signal under PC models?
A: No. If an Interlace signal is used, the screen displays both odd and even horizontal
scanning lines at the same time, thus distorting the picture.
Q: What does the Refresh Rate mean for LCD?
A: Unlike CRT display technology, in which the speed of the electron beam is swept from the
top to the bottom of the screen determines flicker, an active matrix display uses an active
element (TFT) to control each individual pixel and the refresh rate is therefore not really
applicable to LCD technology.
Q: Will the LCD screen be resistant to scratches?
A: A protective coating is applied to the surface of the LCD, which is durable to a certain
extent (approximately up to the hardness of a 2H pencil). In general, it is recommended that
the panel surface is not subject to any excessive shocks or scratches.
Q: How should I clean the LCD surface?
A: For normal cleaning, use a clean, soft cloth. For extensive cleaning, please use isopropyl
alcohol. Do not use other solvents such as ethyl alcohol, ethanol, acetone, hexane, etc.
Q:
Can I change the color setting of my monitor?
A:
Yes, you can change your color setting through OSD control as the following procedures,
1. Press "OK" to show the OSD (On Screen Display) menu
2. Press "Down Arrow" to select the option "Color" then press "OK" to enter color setting, there
are three settings as below.
a. Color Temperature; The six settings are 5000K, 6500K, 7500K, 8200K, 9300K and 11500K.
With settings in the 5000K range the panel appears ‘warm,' with a red-white color tone, while a
11500K temperature yields ‘cool, blue-white toning."
b. sRGB; this is a standard setting for ensuring correct exchange of colors between different
device (e.g. digital cameras, monitors, printers, scanners, etc)
c. User Define; the user can choose his/her preference color setting by adjusting red, green
blue color.
*A measurement of the color of light radiated by an object while it is being heated. This
measurement is expressed in terms of absolute scale, (degrees Kelvin). Lower Kevin
temperatures such as 2004K are red; higher temperatures such as 9300K are blue. Neutral
temperature is white, at 6504K.
Q:
Can the Philips LCD Monitor be mounted on the wall?
A:
Yes. Philips LCD monitors have this optional feature. For standard VESA mount holes on
the rear cover allows the user to mount the Philips monitor on most of the VESA standard
arms or accessories. We recommend to contact your Philips sales representative for more
information.
Screen Adjustments
Q:
When I install my monitor, how do I get the best performance from the monitor?
A:
For best performance, make sure your display settings are set at 1680x1050@60Hz for 22".
Note: You can check the current display settings by pressing the OSD OK button once. The
current display mode is shown in OSD first page.
Q:
How do LCDs compare to CRTs in terms of radiation?
A:
Because LCDs do not use an electron gun, they do not generate the same amount of
radiation at the screen surface.
Compatibility with other Peripherals
Q:
Can I connect my LCD monitor to any PC, workstation or Mac?
A:
Yes. All Philips LCD monitors are fully compatible with standard PCs, Macs and
workstations. You may need a cable adapter to connect the monitor to your Mac system.
Please contact your Philips sales representative for more information.
Q:
Are Philips LCD monitors Plug-and-Play?
A:
Yes, the monitors are Plug-and-Play compatible with Windows® 95, 98, 2000, XP and
Vista.
Q:
What is USB (Universal Serial Bus)?
A:
Think of USB as a smart plug for PC peripherals. USB automatically determines resources
(like driver software and bus bandwidth) required by peripherals. USB makes necessary
resources available without user intervention. There are three main benefits of USB. USB
eliminates "case anxiety," the fear of removing the computer case to install circuit board cards
-- that often requires adjustment of complicated IRQ settings -- for add-on peripherals. USB
does away with "port gridlock." Without USB, PCs are normally limited to one printer, two Com
port devices (usually a mouse and modem), one Enhanced Parallel Port add-on (scanner or
video camera, for example), and a joystick. More and more peripherals for multimedia
computers come on the market every day. With USB, up to 127 devices can run
simultaneously on one computer. USB permits "hot plug-in." No need to shut down, plug in,
reboot and run set up to install peripherals. No need to go through the reverse process to
unplug a device. Bottom line: USB transforms today's "Plug-and-Pray" into true Plug-and-Play!
Please refer to glossary for more information about USB.
Q:
What is a USB hub ?
A:
A USB hub provides additional connections to the Universal Serial Bus. A hub's upstream
port connects a hub to the host, usually a PC. Multiple downstream ports in a hub allows
connection to another hub or device, such as a USB keyboard, camera or printer.

la
y
A: An LCD is made with either a passive matrix or an active matrix display grid. An
active matrix has a transistor located at each pixel intersection, requiring less current to
control the luminance of a pixel. For this reason, the current in an active matrix display
can be switched on and off more frequently, improving the screen refresh time (your
mouse pointer will appear to move more smoothly across the screen, for example). The
passive matrix LCD has a grid of conductors with pixels located at each intersection in the
grid.
Q: What are the advantages of TFT LCD compared with CRT?
A: In a CRT monitor, a gun shoots electrons and general light by colliding polarized
electrons on fluorescent glass. Therefore, CRT monitors basically operate with an analog
RGB signal. A TFT LCD monitor is a device that displays an input image by operating a
liquid crystal panel. The TFT has a fundamentally different structure than a CRT: Each
cell has an active matrix structure and independent active elements. A TFT LCD has two
glass panels and the space between them is filled with liquid crystal. When each cell is
connected with electrodes and impressed with voltage, the molecular structure of the
liquid crystal is altered and controls the amount of inlet lighting to display images. A TFT
LCD has several advantages over a CRT, since it can be very thin and no flickering occurs
because it does not use the scanning method.
A:
Unlike a CRT, an LCD monitor does not have key parts that generate Electro Magnetic
Interference, especially magnetic fields. Also, since an LCD display utilizes relatively low
power, its power supply is extremely quiet.
Ergonomics, Ecology and Safety Standards
Q:
What is the CE mark?
A:
The CE (Conformité Européenne) mark is required to be displayed on all regulated
products offered for sale on the European market. This 'CE' mark means that a product
complies with the relevant European Directive. A European Directive is a European 'Law'
that relates to health, safety, environment and consumer protection, much the same as
the U.S. National Electrical Code and UL Standards.
Q:
Does the LCD monitor conform to general safety standards?
A:
Yes. Philips LCD monitors conform to the guidelines of MPR-II and TCO 99/03
standards for the control of radiation, electromagnetic waves, energy reduction, electrical
safety in the work environment and recyclability. The specification page provides detailed
data on safety standards.
Q:
After I change new PC, I found this information on screen, how can I do?
A:
Because you activate Theft Deterrence function in SmartControl II. Please contact IT
manager or Philips Service Center.
Q:
Why is vertical frequency of 60Hz optimal for an LCD monitor?
A:
Unlike a CDT monitor, the TFT LCD panel has a fixed resolution. For example, an
XGA monitor has 1024x3 (R, G, B) x 768 pixels and a higher resolution may not be
available without additional software processing. The panel is designed to optimize the
display for a 65MHz dot clock, one of the standards for XGA displays. Since the
vertical/horizontal frequency for this dot clock is 60Hz/48kHz, the optimum frequency for
this monitor is 60Hz.
Q:
What kind of wide-angle technology is available? How does it work?
A:
The TFT LCD panel is an element that controls/displays the inlet of a backlight using
the dual-refraction of a liquid crystal. Using the property that the projection of inlet light
refracts toward the major axis of the liquid element, it controls the direction of inlet light
and displays it. Since the refraction ratio of inlet light on liquid crystal varies with the
inlet angle of the light, the viewing angle of a TFT is much narrower than that of a CDT.
Usually, the viewing angle refers to the point where the contrast ration is 10. Many ways
to widen the viewing angle are currently being developed and the most common approach
is to use a wide viewing angle film, which widens the viewing angle by varying the
refraction ratio. IPS (In Plane Switching) or MVA (Multi Vertical Aligned) is also used to
give a wider viewing angle.
Q:
Why is there no flicker on an LCD Monitor?
A:
Technically speaking, LCDs do flicker, but the cause of the phenomenon is different
from that of a CRT monitor -- and it has no impact of the ease of viewing. Flickering in an
LCD monitor relates to usually undetectable luminance caused by the difference between
positive and negative voltage. On the other hand, CRT flickering that can irritate the
human eye occurs when the on/off action of the fluorescent object becomes visible. Since
the reaction speed of liquid crystal in an LCD panel is much slower, this troublesome form
of flickering is not present in an LCD display.
Q:
Why is an LCD monitor virtually low of Electro Magnetic Interference?

DDC Data Re-programming
In case the DDC data mem ory IC or main EEPROM which storage all factory settings
were replaced due to a defect, the serial numbers have to be re-program m ed "A na lo g
DDC IC, Digital DDC IC & EEPROM".
It is advised to re-soldered DDC IC and main EEPROM from the old board onto the new
board if circuit board have been replace d, in this case the DD C data does not need to be
re-programmed.
Additional information
Additional informa tion about DDC (Display Data Channel) may be obtained from Video
Electronics Standards Association (VESA).
Extended Display Identification Data(EDID) information may be also obtained from
VESA.
