The notebook's display is difficult to read
If the display is difficult to read, the following can cause it:
Reflection
Turn the notebook or alter the tilt of the display.
Maximum screen resolution
The screen controller converts the current screen display for the entire screen size. A certain
"fuzziness" cannot always be avoided at resolutions below 1024 x 768.
Defective pixels on the screen
Pixel faults in the form of permanently lit, unlit or different-colored pixels can occur with LCD
monitors. Up to ten pixel faults on the screen do not constitute grounds for exchanging the unit.
Exceptional cases are:
•
if two pixel faults are lying directly next to each other
•
if three pixel faults occur in a 5-mm diameter circle
In these exceptional cases, please contact our customer service center.
