Note:
sRGB is a standard for ensuring correct exchange of
colors
between different devices(e. g. Digital cameras,
monitor,
printers, scanners, etc.)
Using a standard unified color space, sRGB will help
represent pictures taken by an sRGB compatible device
correctly on your sRGB enabled Philips monitor. In that
way,
the colors are calibrated and you can rely on the
correctness
of the colors shown on your screen.
Important with the use of sRGB is that the brightness
and
contrast of your monitor is fixed to a predefined setting
as
well as the color gamut. Therefore it is important to
select the
sRGB setting in the monitor’s OSD.
To do so, open the OSD by pressing the OK button on the
side f your monitor. More the down button to go to color
and ress OK again. Use the right button to go to sRGB.
Then ove the down button and press OK again to exit
the OSD.
After this, please do not change the brightness or
contrast etting of your monitor. If you change either of
these, the onitor will exit the sRGB mode and go to a
color emperature setting of 6500K.

Clock & Phase Adjustment
Due to the different quality of video signal generated from
graphics cards. It is necessary to adjust CLOCK and PHASE
functions for the optimal video display of LCD monitor. So
maybe some flicker appeared as Fig.1 & 2.
Fig.1 Fig.2
Following steps will guide you to make correct adjustment of
CLOCK and PHASE:
a. Restart your computer.
b. Press MENU to bring up OSD menu after the OS
(Operation System) boot up.
c. Press UP or DOWN to select the option of setup
and then press MENU to bring up its submenu as shown in
Fig.3.
d. Select the Clock or Phase adjustment items in submenu
and press UP or DOWN to adjust.
(If the phenomenon as Fig.1, you should adjust “Phase”)
(If the phenomenon as Fig.2, you should adjust “Clock”)
e. Quit OSD by press MENU button to save the settings.

However, CLOCK and PHASE functions are only available while
analog video signal is supplied. Operating unit under digital signal
state, the video clock information can be obtained from graphics
cards directly. So, it is unnecessary to adjust these functions.
OSD Attention signal
The monitor will detect various display situation automatically.
When the monitor detects the problems, the screen will show the
different warning signals to remind you what is happen to your

Troubleshooting Information and Safety
Safety precautions and maintenance
WARNING: 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:
a.
To
protect your display 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.
b.
Unplug the monitor if you are not going to use it for
an extensive period of time.
c.
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 alcohol, solvents or
ammonia-based liquids.
d.
Consult a service technician if the monitor does not operate
normally when you have followed the instructions in this
manual.
e.
personnel.
f.
The casing cover should be opened only by qualified service
Keep the monitor out of direct sunlight and away from
stoves or any other heat source.
g.
Remove any object that could fall into the vents or prevent
proper cooling of the monitor’s electronics.
h.
Do
i.
not block the ventilation holes on the cabinet.
Keep the monitor dry. To avoid electric shock, do not
expose it to rain or excessive moisture.
j.
When positioning the monitor, make sure the power plug
and outlet are easily accessible.
k.
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.
l.
To
avoid the risk of shock or permanent damage to the set,
do not expose the monitor to rain or excessive moisture.
m. IMPORTANT: Always activate a screen saver program during
your application. If a still image in high contrast remains on
the screen for an extended period of time, it may leave an
'after-image' or 'ghost image' on front of the screen. This is a
well-known phenomenon that is caused by the shortcomings
inherent in LCD technology. In most cases, the afterimage will
disappear gradually over a period of time after the power has
been switched off. Be aware, that the afterimage symptom
cannot be repaired and is not covered under warranty.
o. Warning for lifting monitor - Do not use the area underneath
the logo cover to grip or lift the monitor. Placing weight on
the logo cover can cause it to break away from the body and
cause the monitor to fall. When lifting the monitor, place one
hand under the monitor's frame.
*Consult a service technician if the monitor does not operate
normally
have been followed.

An after-image remains

For further assistance, refer to the Consumer Information Centers list
and contact your local Philips distributor.
Adjust the contrast and brightness on On-Screen
Display.(The backlight of the LCD monitor has a fixed life
span. When the screen becomes dark or begins to flicked,
please contact your sales representative).
If an image remains on the screen for an extended
period of time, it may be imprinted in the screen and
leave an after-image. This usually disappears after a
few hours.
This is characteristic of liquid crystal and is not
caused by a malfunction or deterioration of the
liquid crystal. The after-image will disappear after a
peroid of time.
The remaining dots are normal characteristic of
the liquid crystal used in today’s technology.
Definition of Pixel Defects
This section explains the different types of pixel defects and
defines acceptable defect levels of each type. In order to
quality for repair or replacement under warranty, the number
of pixel defects on a TFT LCD panel must exceed these
acceptable levels.
1. Definition of 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.

2. 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:
G
One lit red, green or blue sub pixel
R
B
Two adjacent lit sub pixels:
Red + Blue = Purple
Red + Green = Yellow
Green + Blue = Cyan (Light Blue)
P
Y
C
Three adjacent lit sub pixels
(one white pixel)
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 pixel
Two or three adjacent
dark sub pixels

3. 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.

DDC instructions
General
DDC Data Re-programming
In case the DDC data main EEPROM which
storage all factory settings were replaced due to a defect,
the
serial numbers have to be re-programmed
It is advised to re-soldered DDC IC and main EEPROM from
the old board onto the new board if circuit board have been
replaced, in this case the DDC data does not need to be reprogrammed.
* According to the design concept of this product,
DDC data of VGA/DVI/HDMI interface are saved in
EEPROM(IC 24C02)
Additional information
Additional information 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.
