Working with the notebook
LCD screen
LCDscreenNotes
Fujitsu notebooks have high-quality LCD monitors (TFT). For technical reasons, these
monitors are manufactured for a specific resolution. An optimal, clear picture can only
be e nsu red with the resolutio n intended for the relevant monitor. A resolution which
differs from the specification can result in an unclear picture.
The resolution of your notebook’s monitor is optima lly set at the factory.
With the present sta ndards of production technology, absolutely flawless screen image s
cannot be guaranteed. There may be a few constantly light or dark pixels (picture
elements) on the screen. The maximum permitted number of such faulty pixels is
specified in the international standard ISO 9241-307 (Class II).
Example:
A screen with an HD resolution of 1366 x 768 has 1366 x 768 = 1049088 pixels. E a ch pixel consists
of three subpixels (red, green and blue), making a total of about 3 m illion subpixels. According to ISO
9241-307 (class II), a maximum of 2 light and 2 dark pixels and in addition 5 light or 10 dark subpixels
or an equivalent mix (1 light subpixel counts as 2 dark subpixels) are allowed to be defect ive.
At a resolution of 1600 x 900 = 1440000 pixels, a maximum of 3 light and 3 dark pixels
and in addition 7 light or 14 dark subpixels are allowed to be defective.
Pixel
A pixel consists of
3 subpixels, normally red, green and
blue. A pixel is th
e smallest element that can be generated
by complete funct
ionality of the display.
Subpixel
A su bpixel is a s
eparately addre ssable internal structure
within a pixel t
hat enhances the pixel function.
Cluster A cluster contains two or more defective pixels or
subpixels in a 5 x 5 pixel block.

set the bri
ghtness of you r monitor individually.
