What reviewers say

What Hi-Fi? and Expert Reviews praise the UK 50-inch model's contrast, HDR picture, Tizen interface and responsive gaming. What Hi-Fi? finds default motion processing too strong and loud passages restrained; Expert Reviews finds motion smooth and sound clear. Both note its single 4K 120 Hz HDMI socket and lack of Dolby Vision.

Specifications

Display

Panel: Mini-LED
Panel detail: Quantum Dot LCD with Mini-LED backlight. Exact UK 50-inch reviews identify its panel as VA; the UK maker tables do not specify the LCD matrix for 43, 55, 65 or 75 inches, so it is not generalised. All five sizes are flat.
Resolution: 3840 × 2160 (4K)
Refresh rate: 60 Hz (43″), 120 Hz (50, 55, 65, 75″)
HDR formats: HDR10, HDR10+, HLG
HDR extras: Quantum HDR 1500 is Samsung's UK maker label for 43 and 50 inches; Quantum HDR 2000 for 55, 65 and 75 inches. These names are not comparable measured nit results. HDR10+ Adaptive on the UK maker tables.
Screen finish: Anti-reflection treatment on the reviewed UK 50-inch model; exact coating name not published in its maker table.
Colour range: Samsung's maker table lists 100% Colour Volume for the 50-inch model; this is a marketing colour-volume claim, not a measured DCI-P3 coverage figure for every size.
Picture processing: Quantum Matrix Technology, Ultimate UHD Dimming and AI upscaling on the UK 50-inch maker table. The 4400 Picture Quality Index is a processing score, not 4400 Hz. Samsung's UK newsroom confirmed the QN90A in March 2021 and advertised the 50-inch on sale in a later UK promotion; no maker first-sale month is established.
Picture modes: Filmmaker Mode, Natural and Movie on the UK 50-inch maker table. What Hi-Fi? finds default motion processing and shadow detail need some adjustment on its 50-inch test unit.
Motion handling: Expert Reviews reports native 120 Hz on 50 to 75 inches and 60 Hz on 43 inches; Samsung's maker specification lists no native Hz. Input acceptance and panel refresh are kept distinct.
Viewing angle: Wide Viewing Angle on the maker UK 50-inch table. The 50-inch UK review unit is VA; other sizes may differ by region or size and no LCD-matrix type is assigned to them.

What Hi-Fi? and Expert Reviews identify HDMI 4 as the sole 4K 120 Hz / HDMI 2.1 gaming input on the reviewed 50-inch, with VRR, FreeSync Premium Pro and ALLM. Expert Reviews reports the 43-inch uses a 60 Hz panel, so it is not counted as a full 4K 120 Hz input. eARC uses a different HDMI socket. No US QN90A specifications are applied.
Input lag: 9.2 ms at 60 Hz in Game Mode (What Hi-Fi?) and 9.8 ms in Game Mode (Expert Reviews) on separate exact UK 50-inch tests; these are measured review figures.
Game features: Game Bar, Game Motion Plus, 21:9/32:9 PC view, VRR and FreeSync Premium Pro on the UK 50-inch review set. Features requiring 4K 120 Hz do not apply to the 43-inch panel.
