55-inch TV reviews UK

An LCD panel controls light from a separate backlight. In an LED TV, that backlight uses LEDs; the screen pixels do not produce their own light.

Buying check Check contrast, motion and viewing-angle findings for the model. “LED” alone says little about picture quality.

A display with organic light-emitting pixels that can be controlled individually, including switching off for black.

Buying check Compare brightness, reflection handling and the manufacturer’s panel-care guidance for your viewing habits.

A consumer TV label normally used for an LCD television with quantum dots to help produce colour. It is not the same display structure as OLED.

Buying check Check the backlight and measured performance; a QLED can also be a Mini LED TV.

An LCD backlight using many small LEDs. Implementations vary in their dimming zones and how those zones are controlled.

Buying check More LEDs or zones do not automatically mean better local dimming. Read about bright objects on dark backgrounds.

An OLED display that uses quantum dots for colour conversion. It is distinct from a quantum-dot LCD or QLED television.

Buying check Confirm the panel used in the exact size and generation, then compare the review findings.

An LCD TV adjusts separate backlight areas to make some parts of a scene brighter or darker.

Buying check Look for how the system handles subtitles, small highlights and shadow detail, not only its zone count.

Light can spread visibly around a bright object against a dark background on a backlit display.

Buying check Look at demanding scenes and off-centre viewing in reviews. Aggressive dimming can hide detail while reducing halos.

Contrast describes the difference between light and dark; black level describes how dark the screen can appear. Results depend on measurement conditions and room light.

Buying check Use like-for-like tests. A large advertised contrast ratio is not a complete account of performance.

A nit is one candela per square metre, a unit of screen luminance. A short, small highlight and a full bright screen can produce very different readings.

Buying check Check sustained and real-scene brightness, picture mode and reflections as well as peak nits.

How the picture changes when viewed from the side or above and below the screen. Colour, contrast and brightness may change differently.

Buying check Read findings for the seats you will use. The widest quoted angle does not guarantee a consistent picture.

TV size normally refers to the screen diagonal in inches. Aspect ratio describes its width relative to height; most modern TVs use 16:9.

Buying check Use the cabinet dimensions and stand footprint to check fit. Diagonal size is not the TV’s width.

A display resolution of 1,920 × 1,080 pixels. Resolution is one part of image detail, alongside the source and processing.

Buying check Consider screen size and viewing distance rather than assuming the resolution alone determines sharpness.

For consumer TVs, Ultra HD normally means 3,840 × 2,160 pixels. A 4K screen can also display lower-resolution sources.

Buying check Check the quality of the content and the TV’s processing. A 4K panel does not make every programme native 4K.

A consumer display resolution of 7,680 × 4,320 pixels, with four times the pixel count of 4K UHD.

Buying check Consider available content, viewing distance, price and upscaling. More pixels do not guarantee a better overall picture.

Processing that maps a lower-resolution source to a higher-resolution screen, estimating how additional pixels should appear.

Buying check Read how broadcasts and compressed streams look. Processing cannot recover every detail absent from the original source.

High dynamic range video can carry a wider range of light and colour information than standard dynamic range. Display capability determines how it is reproduced.

Buying check HDR compatibility is not a brightness or contrast score. Compare the critic’s actual HDR assessment.

Different HDR signal formats. HDR10 uses static metadata; HDR10+ and Dolby Vision can use dynamic metadata. HLG is another HDR approach used for broadcasting.

Buying check Check compatibility across the content, app or player, connection and TV. A format badge does not guarantee superior picture quality.

Processing that fits a source’s brightness and colour information into what the display can reproduce.

Buying check Look for preserved bright detail and believable darker areas. The same HDR film can look different on two compatible TVs.

Gamut is the range of colours a display can reproduce; accuracy is how faithfully it reproduces the intended colours. These are different measurements.

Buying check Check results in an appropriate picture mode. A wide gamut or vivid shop setting is not proof of accuracy.

How many times per second a panel updates at a supported operating mode. Native panel refresh is different from a branded motion-processing number.

Buying check Confirm supported resolution and refresh rate for the exact size and HDMI input.

How many image frames a programme or game supplies each second. This belongs to the source, while refresh rate describes the display.

Buying check A higher-Hz TV does not make a game generate more frames. Check the console or PC output as well.

Variable refresh rate lets a compatible display adjust its timing to a source’s changing frame output, helping reduce tearing and stutter.

Buying check Check the supported VRR system, operating range and resolution on the input you will use.

Auto low latency mode lets a compatible source request the TV’s low-latency setting automatically.

Buying check The feature does not state the actual input lag. Read measured game-mode results.

The delay between a video signal reaching the TV and the corresponding image being displayed. It can change with mode and signal format.

Buying check Compare measurements taken at the resolution, refresh rate and picture mode you intend to use.

How quickly a pixel changes between levels or colours. Slow transitions can contribute to visible trails.

Buying check Do not confuse it with input lag. Test methods and transitions vary, so compare equivalent measurements.

Interpolation creates intermediate frames to change motion appearance. Judder describes uneven motion cadence, which may have several causes.

Buying check Try the settings with films and sport. Smoother motion can change a film’s appearance or introduce artefacts.

A digital connection carrying video and audio. The feature set can differ between the ports on one TV.

Buying check Check resolution, Hz, VRR and audio-return support per port. A version label by itself is not a complete compatibility checklist.

Audio Return Channel sends sound from a TV back to a compatible soundbar or receiver over a designated HDMI connection.

Buying check Use the labelled ports and check supported audio formats on both devices.

Enhanced Audio Return Channel extends the audio capabilities of ARC, including support for higher-bitrate formats.

Buying check The TV, audio device, content, source and settings must support the intended path. eARC alone does not guarantee every format will play.

Control signalling that can let connected equipment coordinate functions such as power, input switching and volume. Manufacturers may use different names for it.

Buying check Check daily remote behaviour and settings on both devices; compatible HDMI sockets do not guarantee identical control behaviour.

A digital audio connection using light through an optical cable. Its format capabilities differ from HDMI ARC and eARC.

Buying check Check the soundbar and TV format support and how volume will be controlled.

An audio format and playback approach that can position sound around and above the listener. TVs may decode it, pass it onward or use virtual processing.

Buying check An Atmos badge does not establish the number or position of speakers, or guarantee convincing height effects.

One device forwards a signal to another. The formats and video features it can pass may differ from those it can play or process itself.

Buying check Check the whole route when a console connects through a soundbar or audio returns through the TV.

A content-protection system used by compatible digital video equipment. Protected content may require a supported version throughout the connection.

Buying check Check the TV, source, receiver and any intermediate equipment if protected video fails to display.

The TV’s operating system and connected services, including apps and account features. Availability can vary by country, model and software support.

Buying check Confirm your essential UK apps, accessibility settings and the manufacturer’s support information.

Freeview receives UK terrestrial television through an aerial. Freeview Play adds connected catch-up and on-demand features on compatible equipment.

Buying check Check aerial coverage, internet requirements and the services supported by the exact model.

A UK service delivering live and on-demand television over broadband through compatible TVs or supported streaming equipment.

Buying check Check current device compatibility and service requirements. A generic smart-TV label does not establish Freely support.

A tuner receives a broadcast signal: T/T2 is terrestrial, S/S2 satellite, and C cable. The standard is distinct from a streaming app or service certification.

Buying check Match the signal source, local service and receiver requirements. A socket or tuner label alone does not guarantee every channel.

Two ways of connecting the TV to a home network: wireless and wired. The TV’s supported standard and the home network both affect the connection.

Buying check Check signal quality where the TV will sit. A wired connection may be useful, but neither label guarantees a particular streaming result.

Ways of sending or sharing content from another device. Casting may hand playback to a TV app; mirroring reproduces the other device’s screen.

Buying check Confirm the supported system, apps, phone or computer and network requirements.

The standardised mounting-hole arrangement on the back of a display, usually expressed as horizontal × vertical spacing in millimetres.

Buying check Also check TV weight, screws, spacers, bracket limits, wall suitability and the manufacturer’s installation instructions.

The footprint is the space occupied by the TV’s stand or feet. Cabinet dimensions describe the full television, not just the visible screen.

Buying check Compare furniture width, depth and load capacity; allow for the soundbar, cables and ventilation.

The energy label gives an efficiency class and standardised consumption figures. SDR and HDR consumption can be reported separately.

Buying check Compare consumption figures as well as the letter. The label is not a picture-quality rating or a prediction of your annual bill.

An estimate based on energy use, viewing hours and your electricity unit price. Picture settings, content and standby behaviour affect actual use.

Buying check For a label value E kWh/1,000 h, estimated cost is E × viewing hours ÷ 1,000 × price per kWh. Keep SDR and HDR assumptions clear.

The complete identifier for a TV, including its screen size and relevant suffix. Similar range names can cover different sizes, years or regional editions.

Buying check Match the full code when comparing reviews, specifications and offers. Check the version actually tested.

COR converts usable critic ratings to five points and averages them with equal weight, counting each publisher once. A public score requires at least three critics.

Buying check tbd means the threshold is not met, not a zero rating. Check critic count, review dates and the reviewed version.
