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" flat-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 about 2.4 million dots 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 dots. This corresponds to approx. 0.002 % of the entire screen surface!
The flat screen monitors from Fujitsu Siemens Computers are typically considerably better than
requirements defined in this standard.
The screen becomes darker
The background lighting has a limited lifetime. If your monitor display should become too dark, the
background lighting will have to be exchanged. Please contact our customer service centre.
No sound output
In order for the multimedia functions to be operable, a sound card (audio controller) must be
installed in your computer and properly configured.
Ê
Check whether the audio cable is correctly connected.
Ê
Increase the volume.
