Notes about the LCD screen
High-quality TFT displays with especially bright background lighting are installed in notebooks from
Fujitsu Technology Solutions GmbH. For technical reasons, TFT monitors are manufactured for a
specific resolution. An optimal, clear picture can only be ensured with the correct resolution intended
for the relevant TFT monitor. A monitor resolution which differs from the specification 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, "UXGA" stands for 1600 x 1200 pixels.
Each pixel consists of three so-called subpixels of the colours red, green and blue. As a result, a
UXGA monitor consists of 1600 x 1200 x 3 = 5.760.000 subpixels.

The correct screen resolution for your notebook is specified in the corresponding section in the
chapter "Technical data".
Permanently unlit or lit pixels
The standard of production techniques today cannot guarantee an absolutely fault-free screen
display. A few isolated constantly lit or unlit pixels may be present. The maximum permitted number
of pixel faults is stipulated in the strict 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 faulty subpixels. That is approx. 0.0007% of the entire
number of subpixels.
Pixel A pixel consists of 3 subpixels, normally red, green and blue. A
pixel is the smallest element that can be generated by complete
functionality of the display.
Subpixel A subpixel is a separately addressable internal structure within a
pixel that enhances the pixel function.
Cluster (= group of
faults) A cluster contains two or more defective pixels or subpixels in a
5 x 5 pixel block.
