Panel detail
Panel detail	Panasonic's UK TX-P42G20B, TX-P46G20B and TX-P50G20B manual specifies native Full HD NeoPDP plasma panels. The marketed 600 Hz sub-field drive is not the native image refresh rate, which remains unpublished.	UK Full HD 3D plasma series in 42, 50, 55 and 65 inches. Advertised 600 Hz subfield drive is not a native refresh figure; native refresh is omitted. Active-shutter 3D and two eyewear sets included on the read UK42/50 manual.

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.	NeoPlasma, Infinite Black Pro and High Contrast Filter Pro; THX and ISF calibration controls documented in both exact reviews.
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.	600 Hz Sub-Field Drive and Intelligent Frame Creation are processing/drive descriptions, not native panel refresh. TechRadar's 55-inch review reports 50 Hz judder, improved with IFC Mid.
