What reviewers say

What Hi-Fi? and AVForums find the UK 55-inch Q7F bright, sharp and colourful, with responsive gaming and simple menus. Both note weak off-axis contrast and dark HDR scenes that expose its edge lighting. What Hi-Fi? finds motion imperfect while AVForums finds it good. What Hi-Fi? reports a streaming HDR bug fixed by a later update.

Specifications

Display

Panel: LED LCD
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.
Resolution: 3840 × 2160 (4K)
HDR formats: HDR10, HDR10+, HLG
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+.
Screen finish: Moth Eye anti-reflection treatment in each UK size table.
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: 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.
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: 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 The UK maker tables do not publish native Hz for all four sizes, so the main refresh row is omitted.
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.

Gaming

HDMI ports: 4 (0 HDMI 2.1 at 4K 120 Hz+)
Variable refresh rate: None
HDMI detail: Four HDMI 2.0b inputs on the reviewed UK 55-inch One Connect box, accepting up to 4K 60p with HDR10/HLG and HDCP 2.2 (AVForums). Samsung's separate UK maker tables list four HDMI inputs and ARC on every size; no 4K 120 Hz or eARC capability is claimed.
Input lag: 23.8 ms (What Hi-Fi?) and 17.4 ms (AVForums) measured in Game Mode on separate exact UK 55-inch units; review measurements differ and are not assigned to other sizes.
Game features: Manual Game Mode in the UK maker tables. The 55-inch AVForums test found motion interpolation raised input lag to about 79 ms, compared with 17.4 ms in plain Game Mode.

Smart TV and sound

Smart TV platform: Tizen
Processor: Quad-core
Speakers: 40 W
Wi-Fi: Wi-Fi
Speaker detail: Samsung's separate UK maker tables specify 40 W across all four sizes, with 2.2 channels at 49 inches and 4.2 at 55, 65 and 75 inches. AVForums describes its exact 55-inch review unit as 2.2 channels; the disputed 55-inch channel figure is omitted from the main specification.
Audio features: Dolby Digital Plus, DTS codec, woofer, Multiroom Link and Bluetooth audio in Samsung's UK maker tables. No Dolby Atmos or DTS:X claim is made.
Voice assistants: Voice interaction with UK English support in Samsung's 2017 UK maker tables; today's service availability may differ.
Casting: Samsung Smart View, mobile mirroring, DLNA, Wi-Fi Direct and Bluetooth Low Energy in the UK maker tables.
TV tuners: Twin DVB-T2/C/S2 digital tuners, analogue tuner, CI+ 1.3, UK MHEG 5, programme guide, PVR and time shift in the UK maker tables.
USB: Three USB inputs on the One Connect box in the UK maker tables.
Ethernet: Ethernet LAN built in.
Optical audio out: One optical digital audio output.
