Notes
High-quality TFT displays are installed in notebooks from Fujitsu Siemens Computers GmbH.
For technical reasons, TFT monitors are manufactured for a speci
fi
c resolution. An optimal,
clear picture can only be ensured in the resolution intended for the particular TFT monitor. A
monitor resolution which differs from the speci
fi
cation can result in an unclear picture.
The monitor resolution is understood to be the number of horizontal and vertical pixels (i.e. "picture
elements") which make up the monitor display. For example, "WUXGA" stands for 1920 x 1200
pixels. Each pixel consists of three so-called subpixels of the colours red, green and blue. As
a result, a WUXGA monitor consists of 1920 x 1200 x 3 = 6,912,000 subpixels.

The screen resolution of the LCD screen of your notebook is optimally set at the factory.
Permanently unlit or lit pixels
The standard of production techniques today cannot guarantee an absolutely fault-free screen
display. A few isolated constant lit or unlit pixels may be present. The maximum permitted number
of pixels faults is stipulated in the stringent international standard ISO 13406-2 (Class II).
Example:
A 15" LCD screen monitor with a resolution of 1024 x 768 has 1024 x 768 = 786432 pixels. Each
pixel consists of three subpixels (red, green and blue), so there are almost 2.4 million subpixels
in total. According to ISO 13406-2 (Class II), a maximum of 4 pixels and 5 subpixels may be
defective, i.e. a total of 17 faulted subpixels. That is approx. 0.0007 % of the entire subpixel!
Background lighting
TFT monitors are operated with background lighting. The luminosity of the background
lighting can decrease during the period of use of the notebook. However, you can
set the brightness of your monitor individually.
