sRGB is a standard
Optical Characteristics
SRGB
for ensuring correct exchange of colors between
different devices (e.g. digital cameras, monitors, 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 monitors. 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 OKbutton on the front of your
monitor. Use the down button to go to Adjust Color and press OKagain.
Then move the down button to go to sRGB and press OKagain.
After this, please do not change the brightness or contrast setting of your
monitor. If you change either of these, the monitor will exit the sRGB
mode and go to a color temperature setting of 6500K.
For more information on sRGB, please visit: www.srgb.com

shows the power consumption and signaling of this automatic power
saving feature:
VESA Mode Video H-sync V-sync Power Used LED color

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 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 15" 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 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 appear as pixels or sub pixels that are always lit or
'on'. These 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)
Three adjacent lit
sub pixels
(one white pixel)
Black Dot Defects Black dot defects appear as pixels or sub
pixels that are always dark or 'off'. These are the types of black
dot defects:
One dark sub pixel Two or three adjacent dark sub pixels
Proximity of Pixel Defects
Because pixel and sub pixels defects of the same type that are
near to one another may be more , 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.
Note:
*1or 2 adjacent sub pixel defects =1dot defect
All Philips monitors are ISO13406-2 Compliant
