HDR extrasSamsung's QHDR 1500 is a product label, not a measured 1500-nit result.

Motion handlingAVForums identifies a 100 Hz native panel in its UK 55-inch test and finds motion mostly good; What Hi-Fi? finds no ideal processing setting. The UK maker tables do not publish native Hz for all four sizes, so the main refresh row is omitted.Expert Reviews found 60 Hz native on the UK 49-inch and 120 Hz on 55-inch and larger variants. AVForums saw occasional 50 Hz frame skipping on its 55-inch test unit.
Viewing angleBoth independent UK 55-inch reviews find colour and black levels deteriorate away from the centre despite Samsung's Q Viewing Angle claim.Samsung specifies Wide Viewing Angle on 55-inch and larger UK variants, but not on the 49-inch. The 55-inch lacks the higher-tier Ultra Wide Viewing Angle layer according to AVForums and Expert Reviews.
