Panasonic markets its plasma screens to businesses, citing their applications for meetings and live events. The screens are large, thin and high-contrast but they run the risk of image retention, or burn-in, when they display a still image for a long time. Panasonic's default Extended Life Settings seek to combat image retention. When a still image stays on the screen, the settings move the image and suppress image contrast. Changing these settings reduces your screen's life, so if you change them, consider resetting the screen to its original settings.
