"Q.
Afterimages appear when I continuously display one image on screen and change the image to different one, is this a problem?
A.
When a pattern is continuously imprinted on an LCD monitor screen, "afterimage" or "residual images" may appear. Unlike CRT monitors' "burnt phosphor" by which an image is permanently etched into the phosphor. LCD monitors' "afterimage" is reversible. To reverse this phenomenon, run the monitor with a gray pattern displayed or turn the power off completely. It all depends on the level of afterimage, though, it usually takes about three times the amount time for the afterimage to disappear as the time the original image was displayed that caused the phenomenon. To prevent this problem, it is recommended to set the "Off Timer" function. Please note that the afterimage is different from the ghost or blur of an image that may appear when displaying motion pictures due to slow response times."
QUESTION: How can I avoid Image Retention on my Monitor?
ANSWER: Image retention is a slow (e.g. 10 seconds) fade out of an image that was displayed on the screen for an extended period of time. This phenomenon is referred to as image sticking in EIZO DT documentation. Although stuck images usually fade out, in extreme cases, static images displayed over a long period of time may be permanently "burned in" to the screen. This is one reason why EIZO Display Technologies recommends the use of a screen saver, to ensure images that are not being viewed are replaced by dynamic changes.
