Precautions

Operating precautions

Continuous operation of the display with the same image may result in
some image sticking on the LCD panel. Over 10 hours operation with the
same image content is not recommended.

Switching on DPMS on display and PC and activating a good screen saver
may decrease the risk of image sticking (image retention).
