The marketed 600 Hz sub-field drive is not the native image refresh rate, which remains unpublished.	UK G15 Full HD NeoPlasma series with 42 and 50-inch panels and active-shutter 3D.

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.	G15 NeoPlasma with Infinite Black Pro and High Contrast Filter Pro; THX and ISF calibration modes; active 3D. Subfield-drive advertising is not native refresh.
Picture modes
Picture modes	Dynamic, Normal, Cinema, THX, Game and Photo where input-appropriate; ISFccc setup unlocks Professional 1 and 2 with per-input calibration settings.	–
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.	Intelligent Frame Creation and 24p Smooth Film are processing modes. AVForums observed subtle 50 Hz break-up during fast pans on its 50-inch review unit.
