LCDscreenNotes
High-quality TFT displays are installed in notebooks from Fujitsu Technology Solutions GmbH. For
technical reasons, TF T monitors are man ufactured 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 screen resolution of the LCD monitor of your notebook is optimally set at the factory.
Permanently unlit or lit p ixels
The standard of production techniques today cannot guarant ee an absolutely fault-free screen
display. A few isolated constantly lit or unlit pixels may be present. The maximum permitted number
of such faulty pixels is stipulated in the strict international standard ISO 13406-2 ( Class II).
Example:
A 10" LCD screen monitor with a resolution of 1024 x 600 has 1024 x 600 = 614,400 pixels. Each
pixel consists of thre e subpixels (red, green and blue), so there are almost 1.8 million subpixels in
total. According to ISO 13406-2 (Class II), a maximum of 2 pixels and 3 subpixels may be defective,
i.e. a total of 9 defective subpixels. That is approximately 0.0005 % of the entire number of subpixels.
Background lighting
TFT monitors are operated with ba ckgro und lighting. The lum inosity of the background
lighting can decrease during the period of use of the notebook. However, you can
set the brightness of your monitor individually.
