Display
PanelLED LCDPlasma
Panel detailPanasonic specifies LED LCD with Local Dimming Pro. AVForums identified a VA panel and 18 direct-lit dimming zones on its 55-inch sample; these findings are not claimed for every size.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 The marketed 600 Hz sub-field drive is not the native image refresh rate, which remains unpublished.
Resolution3840 × 2160 (4K)1920 × 1080 (Full HD)
HDR formatsHDR10None
HDR extrasHDR support was added by Panasonic's later firmware upgrade for the 50-, 55- and 65-inch UK CX802B models. The 40-inch model was excluded.–
Picture processingPanasonic lists Studio Master Drive, 4K Studio Master Processing, Local Dimming Pro and Studio Master Colour.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.
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 handlingPanasonic's Intelligent Frame Creation is motion processing, not a stated native panel refresh rate.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.
Viewing angleAVForums and HDTVTest both found the reviewed 55-inch VA panel best viewed from near the centre.–
