Picture processing
Picture processing	Panasonic's second-generation NeoPDP panel, Intelligent Frame Creation, Resolution Enhancer and advanced white-balance, gamma and colour-management controls. The THX picture mode is certified; the 600 Hz sub-field drive is marketing for the panel drive rather than native frame refresh.

Motion handling
Motion handling	HDTVTest measured 900 lines of motion resolution with Intelligent Frame Creation off and 1080 with it on, but saw some ball shimmer during sports. It found 1080p/24 playback free of telecine judder. These are measurements of the reviewed 42-inch set, not a native refresh specification.	HDTVTest measured about 1080 lines of motion resolution and about 24 ms input lag in Game mode on its 42-inch review sample; these figures are not claims for every size.
