NOTICE
Burn-in effect, backlighting
A permanent picture with bright screen objects can have a burn-in effect. An outline of the
image is displayed for a while; the longer the image has been burnt-in, the longer the
outline will be visible. In severe cases, the outline of the image will remain on the screen
permanently.
The image outline usually disappears on its own when the screen remains switched off for
some time or when it shows changing content as with screen savers. Screen savers that
use active black when the backlight is on reduce the burn-in effect.
•
Switch on the screensaver.
The brightness of the backlight decreases incrementally during operational life. You can
extend the service life of the display and the backlight with the following measures:
•
Reduce the backlight.
•
Pay attention to the length of time the backlight is activated.

Defective pixels in the display
The manufacturing process of modern displays does not currently guarantee that all pixels of
the display are perfect. It is therefore inevitable that the display will contain a small number
of defective pixels. This does not limit the function in any way provided the defective pixels
are not all in one location.
Additional information is available in section "Technical specifications (Page 98)".
