What is afterimage burn-in?

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.

――The best way to protect the product from afterimage burn-in is switching the power off or setting the PC or system to run a screen saver when not in use. Also, Warranty service may be limited depending on instruction guide.

•• Powering Off, Screen Saver and Power Saving Mode

-- Power off the product for 4 hours after using it for 20 hours. -- Power off the product for 2 hours after using it for 12 hours.

-- Go to Display Properties > Power Supply on your PC and set the product to power off as required. -- Using a screen saver is recommended.

It is best to use a single-color or moving-image screen saver.

•• Regular color Change -- Use 2 colors

Switch between 2 colors every 30 minutes as shown above.
