Permanently unlit or lit pixels
The standard of production techniques today cannot guarantee an absolutely fault-free monitor. 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 subpixels (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 subpixels may be defective, i. e.
a total of 25 faulted dots. This corresponds to approx. 0,00062% 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.
Image of last screen display still visible
If you switch from a high-contrast display (for example black lines/characters on a white
background) to a picture of medium brightness, you may be able to see a faint image of the previous
display for a time. This phenomenon is not due to a monitor defect but to the technology used.
