Panel detail
Panel detail	Flat quantum-dot LED-backlit LCD. AVForums identifies its tested UK 55-inch panel as 10-bit VA with LEDs along the bottom edge; Samsung's UK size tables do not specify the LCD matrix or native refresh rate for the other sizes.	Direct LED backlight with full-array local dimming and Triluminos colour.

HDR formats
HDR formats	HDR10, HDR10+, HLG	HDR10, HLG, Dolby Vision
HDR extras
HDR extras	Samsung'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+.	Sony announced Dolby Vision support for XF90 and now lists the series as compatible; it arrived through a firmware update after launch.
Peak brightness
Peak brightness	–	AVForums measured about 1,000 nits in its brightest HDR mode and 705 nits in Cinema Pro on its UK 55-inch review sample; these are test results, not maker series specifications.
Screen finish
Screen finish	Moth Eye anti-reflection treatment in each UK size table.	–
Colour range
Colour range	Samsung'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.	–
Picture processing
Picture processing	Samsung 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 X-Motion Clarity.
Picture modes
Picture modes	Film 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 handling
Motion handling	AVForums 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 The UK maker tables do not publish native Hz for all four sizes, so the main refresh row is omitted.	Sony describes X-Motion Clarity but its exact UK size sheets do not publish a native refresh figure, so no Hz value is assigned to the series.
Viewing angle
Viewing angle	Both independent UK 55-inch reviews find colour and black levels deteriorate away from the centre despite Samsung's Q Viewing Angle claim.	AVForums and Expert Reviews report the 55-inch LCD's contrast and colour degrade when viewed from the side.
