manual before you use your monitor.
It contains important information and
notes regarding the operation of 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

1.1 Safety precautions and
maintenance
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, very strong bright
lights and away from any other heat
source. Lengthy exposure to this
type of environment may result in
discoloration and damage to the
monitor.
• Keep the display away from oil. Oil
may damage the plastic cover of the
display and void the warranty.
• 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 Service
contact information listed in
Regulation & Service Information
Manual.)
• Operate under the specified power
supply. Be sure to operate the
monitor only with the specified
power supply. Use of an incorrect
voltage will cause malfunction and
may cause fire or electric shock.
• Do not disassemble the AC adapter.
Disassembling the AC adapter may
expose you to the danger of fire or
electric shock.
• Protect the cable. Do not pull or
bend the power cable and signal
cable. Do not place the monitor
or any other heavy objects on the
cables, if damaged, the cables may
cause fire or electric shock.
• To avoid potential damage, for
example the panel peeling from the
bezel, ensure that the monitor does
not tilt downward by more than -5
degrees. If the -5 degree downward
tilt angle maximum is exceeded, the
monitor damage will not be covered
under warranty.

1. Important
• 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.
• Excessive usage of monitor can
cause eye discomfort, it’s better to
take shorter breaks more often at
your workstation than longer breaks
and less often; for example a 5-10
minute break after 50-60-minute
continuous screen use is likely to
be better than a 15-minute break
every two hours. Try to keep your
eyes from eye strain while using the
screen for a constant period of time
by :
• Looking at something varying
distances after a long period
focusing on the screen.
• Conscious Blinking often while
you work.
• Gently closing and rolling your
eyes to relax.
• Reposition your screen to ap-
propriate height and angle ac-
cording to your height.
• Adjusting the brightness and
contrast to appropriate level.
• Adjusting the environment light-
ing similar to that of your screen
brightness, avoid the uorescent
lighting, and surfaces that don’t
reect too much light.
• Seeing a doctor if your symp-
toms.
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.
• Oil-based cleaning solutions may
damage the plastic parts and void
the warranty.
• 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.
• Temperature: 0-40°C 32-104°F
• Humidity: 20-80% RH
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.
3
1. Important
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
that 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
Service contact information listed
in Regulation & Service Information
Manual.)
• 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.

Description of the On Screen Display
What is On-Screen Display (OSD)?
On-Screen Display (OSD) is a feature in
all Philips LCD monitors. It allows an end
user to adjust screen performance or
select functions of the monitors directly
through an on-screen instruction
window. A user friendly on screen
display interface is shown as below:
271E1S/271E1SD/272E1SA/275E1/275E1S
/275E1E
278E1/278E1A
Basic and simple instruction on the
control keys
In the OSD shown above, you can press
buttons at the front bezel of the
monitor to move the cursor, and press
OK button to confirm the choice or
change.
The OSD Menu
Below is an overall view of the structure
of the On-Screen Display. You can use
this as a reference when you want to
work your way around the different
adjustments later on.
Note
If this display has "DPS" for ECO design,
the default setting is "ON" mode: it
makes the screen looks slightly dim; for
optimum brightness, enter to the OSD
to set "DPS" to "OFF" mode.

gaming and video images or displays
clear, readable text for office work.
By reducing your monitor's power
consumption, you save on energy costs
and extend the lifetime of your monitor.
How does it work?
When you activate SmartContrast, it will
analyse the content you are displaying
in real time to adjust colors and control
backlight intensity. This function will
dynamically enhance contrast for a great
entertainment experience when viewing
videos or playing games.

Adaptive Sync
PC gaming has long been an imperfect
experience because GPUs and monitors
update at different rates. Sometimes
a GPU can render many new pictures
during a single update of the monitor,
and the monitor will show pieces of
each picture as a single image. This is
called “tearing.” Gamers can fix tearing
with a feature called “v-sync,” but the
image can become jerky as the GPU
waits on the monitor to call for an
update before delivering new pictures.
The responsiveness of mouse input and
overall frames per second are reduced
with v-sync, too. AMD Adaptive Sync™
technology eliminates all of these
problems by letting the GPU update the
monitor the moment a new picture is
ready, leaving gamers with unbelievably
smooth, responsive, tearing-free games.

7.1 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 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 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.
subpixel
pixel
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.
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.
One lit red, green or blue sub pixel.
Two adjacent lit sub pixels:
- Red + Blue = Purple
- Red + Green = Yellow
- Green + Blue = Cyan (Light Blue)
31
7. Customer care and warranty
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. 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.
32
7. Customer care and warranty
BRIGHT DOT DEFECTS ACCEPTABLE LEVEL
1 lit subpixel 3
2 adjacent lit subpixels 1
3 adjacent lit subpixels (one white pixel) 0
