Panel detailPanasonic'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 The marketed 600 Hz sub-field drive is not the native image refresh rate, which remains unpublished.UK TH-37PX70B has 1024 × 720 native pixels, TH-42PX70B has 1024 × 768 and TH-50PX70B has 1366 × 768. The accepted 1080p signal is scaled to the panel. Neither the maker's listed PC scanning frequencies nor mains frequency establish native panel refresh.

Picture processingPanasonic'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.V-Real 2 is named in TechRadar's exact 42-inch review; Panasonic's UK menu specifies colour management, P-NR noise reduction and 3D-COMB for analogue signals.
Picture modesDynamic, Normal, Cinema, THX, Game and Photo where input-appropriate; ISFccc setup unlocks Professional 1 and 2 with per-input calibration settings.Dynamic, Normal and Cinema; each keeps separate picture settings by input signal.
Motion handlingHDTVTest 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.Native panel refresh is not published in the UK manual. TechRadar saw judder on HD camera pans; Stuff described smooth Blu-ray motion. These are viewing judgements, not refresh-rate specifications.
