Due to the nature of the manufacturing of this product, approximately 1 pixel per million (1ppm) may be 
brighter or darker on the panel.  
This does not affect product performance.

Leaving the screen fixed on a stationary image for an extended period of time may cause afterimage 
burn-in or defective pixels.

 

-

Activate power-saving mode or a dynamic screen saver if you will not be using the product for 
an extended period of time.

Afterimage burn-in should not occur when the LCD panel is operating normally. Normal operation refers 
to a continuously changing video pattern. If the LCD panel displays a fixed pattern for an extended period 
of time (more than 12 hours), a slight voltage difference may occur between the electrodes in pixels that 
control the liquid crystals.
Such a voltage difference between electrodes increases with time and makes the liquid crystals thinner. 
When this occurs, a previous image can remain on the screen when the pattern changes. To prevent this, 
the accumulated voltage difference should be reduced.

 

― Afterimage burn-in should not occur when an LCD panel is operating in proper conditions.
