3. Recommended Usage
In order to get the most out of your LCD, use the following recommended guidelines to optimize
the display.
3.1 Burn-In Versus Temporary Image Retention
Burn-in causes the screen to retain an image essentially forever, with little or no way to correct
the problem. Under normal use, an LCD will not experience burn-in, as plasma displays do, nor
will it retain images in any way.
Normal use of an LCD is defined as displaying continuously changing video patterns or images.
However, LCDs can experience
temporary
image retention when recommended usage
guidelines are not followed.
What is Temporary Image Retention?
Temporary image retention (TIR) can occur when a static image is displayed continuously for
extended periods of time (12 hours or longer). An electrical charge differential may build up
between the electrodes of the liquid crystal, which causes a negative-color video image
(color-inverted and brightness-inverted version of the previous image) to be retained when a new
image is displayed. This behavior is true for any LCD device from any LCD manufacturer.
TIR is not covered under warranty. See standard warranty terms and conditions for details. Here
are some guidelines to help you avoid TIR:
• Use the LCD to show a screen saver, moving images or still pictures that change regularly.
When using high-contrast images, reposition the images frequently.
• Turn off the LCD when it is not in use. To use your source computer’s Power Options
Properties, set up your computer to turn off the display when not in use.
