Windows Me, Windows 2000, Windows XP or OS/2 with Windows emulation installed is
used, the basic monitor settings can be set with the floppy disk supplied.
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 17" flat-screen monitor with a resolution of 1280 x 1024 has 1280 x 1024 = 1310720
pixels. Each pixel consists of three sub pixels (red, green and blue), so there are about 4 million
dots in total.
According to ISO 13406-2 (Class II), a maximum of 6 pixels and 7 sub pixels may be defective, i. e.
a total of 25 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 Help Desk.
