Does the TV have a feature to help reduce image retention?

Panasonic Plasma TV models feature a pixel orbiter, which helps reduce image retention. The pixel orbiter is available in all picture modes except for THX mode. However, please be aware that leaving a still image on the screen for an extended period can cause screen image retention, so it's important to avoid doing so to protect your TV's display.

Note:

Not all Plasma TVs have THX mode. The pixel orbiter is a menu item in current models. In earlier models the feature was automatic and did not appear in the menu.
