HDR extrasSamsung's QHDR 1500 is a product label, not a measured 1500-nit result. Samsung confirmed HDR10+ on its 2017 UHD range through Prime Video in December 2017; the initial UK maker tables do not specify HDR formats or whether other sources gained HDR10+.HDR10 is confirmed in the exact-model reviews. HLG was described as a planned firmware addition at launch and is not included without a verified completed update. Dolby Vision is unsupported on the X1, per AVForums.
Peak brightness–HDTVTest measured 880 cd/m² after D65 calibration on its UK 65-inch sample; AVForums measured 936 nits on a 10% window with different settings.
Screen finishMoth Eye anti-reflection treatment in each UK size table.–
Colour rangeSamsung's March 2017 launch claimed 100% colour volume for the QLED family. AVForums measured 95% DCI-P3 xy on its exact UK 55-inch test; this is a reviewer measurement, not a maker specification for every size.HDTVTest measured 92% DCI-P3 on its calibrated 65-inch sample; AVForums measured 87% DCI-P3 xy. These are reviewer measurements, not maker series figures.
Picture processingSamsung UK lists Auto Motion Plus, Supreme UHD Dimming, Q Viewing Angle and a 3100 Picture Quality Index. The index is a processing score, not the native panel refresh rate. Samsung Spain calls the 55-inch processor Q Engine, while the UK table says quad-core.4K X-Reality PRO, X-tended Dynamic Range PRO, Object-based HDR remaster, Super Bit Mapping 4K HDR and Motionflow XR 1000.
Picture modesFilm Mode and Auto Motion Plus in each UK maker table. What Hi-Fi? recommends reducing contrast enhancement and sharpening on its 55-inch test unit.–
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 The UK maker tables do not publish native Hz for all four sizes, so the main refresh row is omitted.Sony UK specifies native 100 Hz. HDTVTest measured a 120 Hz panel refresh on its 65-inch British review sample; the conflicting measured rate is not substituted into the maker-backed series field.
Viewing angleBoth independent UK 55-inch reviews find colour and black levels deteriorate away from the centre despite Samsung's Q Viewing Angle claim.Both AVForums and HDTVTest found the 65-inch VA LCD's best picture concentrated near the centre.
