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.Curved edge-lit LCD with 4200R curvature and active-shutter 3D. Samsung's 1000 Clear Motion Rate is a processing label, not the native panel refresh rate; the UK specification does not publish native Hz.
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.The UK 55-inch specification lists Micro Dimming Ultimate, Auto Depth Enhancer and 1000 Clear Motion Rate but says Precision Black local dimming is absent. HDTVTest found that Cinema Black darkens letterbox bars, though some settings shifted the whole picture's brightness.
Picture modes–Movie mode and ten-point white balance controls allowed very accurate greyscale on the HDTVTest and AVForums 55-inch test sets. Samsung's UK table confirms 2D-to-3D conversion and two included active glasses.
Motion handlingPanasonic's Intelligent Frame Creation is motion processing, not a stated native panel refresh rate.HDTVTest measured 1080 lines of motion resolution with Motion Plus engaged versus 300 without it on its 55-inch unit; these are reviewer measurements, not panel Hz. It also saw occasional motion hiccups after scene cuts and mild 3D film judder.
Viewing angleAVForums and HDTVTest both found the reviewed 55-inch VA panel best viewed from near the centre.HDTVTest found blacks and colours washed out beyond about 40 degrees off-axis on its 55-inch review unit. The curve did not materially improve its viewing angle.
