LG C5 65-inch OLED: the easy premium-TV choice, unless your room exposes its weak spots

Posted on 13 Jul 2026 by Julian House

Product research and owner feedback


The 65-inch LG C5 OLED65C54LA is the sort of television that makes a strong first impression without demanding much explanation. OLED blacks are genuinely black, films have convincing depth, viewing angles are wide and all four HDMI ports are ready for modern gaming hardware. Owners are largely enthusiastic about the picture and gaming performance. The less flattering feedback centres on reflections in bright rooms, average built-in sound and the fact that the C5 is an evolution of the C4 rather than a dramatic reinvention.


How we researched this: Discount Promo Codes has not personally tested this television. We checked the current Currys product page, LG’s official UK specification, laboratory-style testing from RTINGS, specialist reviews from TechRadar and What Hi-Fi?, and discussions from LG OLED owners. Isolated panel or software complaints are treated as individual experiences rather than proof of a model-wide fault.




The short buying case


The LG C5 is one of the safest premium television choices for households that mix films, streaming, sport and gaming. Its 4K OLED evo panel uses self-lit pixels, so dark scenes do not have the grey haze or blooming that can appear around bright objects on conventional backlit televisions. LG pairs the panel with its Alpha 9 AI Processor Gen8, Dolby Vision, HDR10, HLG and webOS.

Currys lists a native 120Hz refresh rate, four HDMI 2.1 inputs, a five-year guarantee and LG’s Brightness Booster Ultimate processing. The television supports 4K gaming at up to 120Hz from current consoles and up to 144Hz from compatible PCs, with VRR, AMD FreeSync Premium, Nvidia G-Sync compatibility, ALLM and a dedicated Game Optimiser menu. Check the current Currys specification and customer rating.

The C5 is strongest in a room where lighting can be controlled and where picture quality matters more than built-in audio. A very bright lounge with windows directly opposite the screen may favour an anti-glare OLED or high-end Mini-LED television instead.

Why owners and reviewers rate the C5 so highly


OLED contrast still transforms films


The main attraction remains pixel-level control. Every pixel can switch off independently, which gives dark scenes true black rather than approximated black. RTINGS found the C5 excellent across films, television and gaming, with inky blacks, strong colours and impressive HDR image quality. Read the RTINGS LG C5 test.

What Hi-Fi? described the C5 picture as rich, punchy and crisp, with strong image solidity and an appealing balance between vibrancy and authenticity. That matters because some showroom modes make OLED colour look exaggerated. The better picture presets are capable of looking cinematic rather than simply bright. See the What Hi-Fi? C5 verdict.

The C5 is an unusually complete gaming television


All four HDMI sockets support HDMI 2.1 bandwidth rather than reserving the best gaming connection for one or two ports. That gives owners room for a PlayStation 5, Xbox Series X, gaming PC and eARC sound system without constantly swapping cables. RTINGS recorded very low input lag and near-instantaneous pixel response, producing sharp motion and a responsive feel. Read the detailed gaming findings.

Owners on Reddit repeatedly praise the Game Optimiser interface and compatibility with Xbox Series X, PS5 and PC. One C5 owner described the set as bright, clear and excellent with Xbox, while another highlighted the improvement in brightness and colour over an older LG C2. These are personal impressions, but they match the formal test results. Read the C5 owner discussion.

HDR highlights are brighter than older C-series OLEDs


The C5 is not as bright as LG’s flagship G-series or the strongest QD-OLED televisions, but it is brighter than earlier mainstream C-series sets. TechRadar praised its HDR presentation and found that the improved brightness gave highlights greater impact while preserving OLED black levels. Read the TechRadar C5 review.

This makes the C5 particularly persuasive for evening films, streamed drama and games with dark scenes punctuated by bright lights. The panel does not need to brighten the entire picture to create contrast; a small bright object can sit beside true black.

The picture holds up from wider seating positions


OLED viewing angles are a practical advantage in a 65-inch family television. Colours and contrast remain more consistent for people seated off-centre than they do on many VA-panel LED televisions. That makes the C5 easier to use in a broad living room where not every chair faces the centre of the screen.

webOS covers the main streaming services


LG’s webOS platform includes the major UK streaming applications and Freeview Play support. Currys highlights easy access to common services, while reviewers generally find the platform responsive and feature-rich. LG also commits to several years of webOS updates under its Re:New programme, although individual app availability always depends on the service provider. See LG’s current C5 features.

The design stays slim without forcing wall mounting


The C5 is thinner than most conventional LED televisions and includes a tabletop stand, unlike some gallery-style televisions designed primarily for wall mounting. It looks premium without requiring professional installation, although the 65-inch panel still needs two people to lift safely.


The reasons not to buy it blindly


Reflections can distract in dark scenes


The glossy screen can reflect windows, lamps and people sitting opposite it. TechRadar found that the C5 handled brighter scenes reasonably well but struggled more with reflections during dark films. Owner discussions are divided: some use the television comfortably in rooms with large windows, while others find the mirror-like effect distracting. See TechRadar’s reflection findings and read the owner discussion.

Room layout matters more than a generic “good for bright rooms” label. A window beside the television is less troublesome than a bright window directly opposite it. Curtains, blinds and careful lamp positioning can make a bigger difference than picture settings.

The built-in sound does not match the picture


TechRadar and What Hi-Fi? both considered sound one of the weaker areas. Dialogue is generally clear enough for ordinary television, but bass, scale and cinematic impact are limited by the slim cabinet. Read the sound criticism in the What Hi-Fi? review.

A soundbar is not mandatory on day one, but buyers spending heavily on a 65-inch OLED should budget for one if films, sport or gaming audio matter. One HDMI input supports eARC for passing high-quality audio to a compatible soundbar or AV receiver.

It is only a modest upgrade over the LG C4


Reviewers consistently describe the C5 as excellent but evolutionary. TechRadar’s verdict notes that it is a slight upgrade over the C4, and enthusiast discussions often recommend buying the older model when the price difference is large. See the C4 comparison in TechRadar’s verdict.

The correct choice is therefore price-sensitive. The C5 is preferable when the gap is modest and its extra brightness, newer processing and longer remaining software life are valuable. A heavily discounted C4 may deliver very similar real-world enjoyment for less.

OLED burn-in risk has not disappeared


Modern OLED care systems reduce risk, but permanent image retention remains possible after prolonged, repeated display of static content. News tickers, game HUDs, channel logos and using the TV as a desktop monitor for long hours deserve more care than varied film and television viewing. RTINGS still lists burn-in as a technology-level risk, while owner discussions generally advise leaving LG’s protection features enabled. Read C5 owner advice about OLED care settings.

The interface includes recommendations and AI features not everyone wants


webOS is capable, but it is not a neutral list of apps. The home screen includes recommendations and promotional areas, while the AI button and personalised features may feel unnecessary to buyers who simply want a television and HDMI inputs. Most can be ignored or reduced through settings, but the platform is busier than a basic streaming menu.

Panel uniformity can vary between individual OLED televisions


Enthusiast forums contain reports of tinting, vertical banding and uneven near-black screens on individual OLED panels. Many owners never notice these issues in normal viewing. Testing hours of artificial grey slides can reveal differences that are invisible in films, so the sensible check is whether real content shows a distracting defect during the retailer return period.

Who is the LG C5 65-inch for?


The C5 suits film and streaming fans who can control room lighting, gamers with several HDMI 2.1 devices, and families that need wide viewing angles. It is also an appealing upgrade from an older LED television because its black level, motion response and HDR contrast are immediately visible.

It is less suitable for rooms flooded with direct daylight, households that leave static news or sports channels running all day, or buyers who expect the built-in speakers to produce cinema-scale sound. Owners of a recent LG C3 or C4 should compare side by side before assuming the improvement justifies replacement.


The televisions it needs to beat


LG C4 65-inch OLED


The C4 is the value comparison. It retains four HDMI 2.1 connections, Dolby Vision, strong gaming support and excellent OLED contrast. The C5 is brighter and newer, but the difference may not justify a large premium. Check remaining stock, warranty and the final delivered price rather than comparing launch prices.

LG G5 65-inch OLED


The G5 is the step-up choice for people who want greater brightness, stronger HDR highlights and a more premium wall-mounted design. It costs more, and its advantages are easiest to appreciate in demanding HDR content or brighter rooms. C5 owners on Reddit often say they are happy without the G5, while others prefer paying for the flagship brightness. Read owners discussing C5 versus G5 regret.

Samsung S90F OLED


The S90F is a direct alternative for buyers prioritising bright, saturated HDR colour and gaming. Depending on size and regional panel supply, Samsung’s QD-OLED technology can produce stronger colour volume. Samsung does not support Dolby Vision, which may matter to film and streaming viewers. Owner debates tend to favour Samsung for brightness and colour intensity, and LG for Dolby Vision, processing and a more established gaming interface. Read the C5 versus S90F discussion.

Sony Bravia 8 OLED


Sony’s Bravia 8 is worth comparing for film processing, motion and sound integration. It usually has fewer HDMI 2.1 inputs than the LG, making the C5 easier for households with multiple gaming devices. Sony may appeal more to viewers who prioritise natural processing and broadcast television over gaming flexibility.

A premium Mini-LED television


A Mini-LED model from Samsung, Sony, TCL or Hisense can produce greater full-screen brightness and may be a safer fit for very bright rooms or heavy static-content use. It cannot match OLED’s perfect pixel-level black without some blooming around bright objects. The choice depends on room conditions rather than one display technology being universally better.


Questions shoppers ask before buying the LG C5


These questions repeatedly appear across product searches, reviews and owner forums. They are answered from the verified specification and available evidence rather than presented as measured search-volume data.

Is the LG C5 worth buying over the C4?


It depends mainly on the price difference. The C5 is brighter, newer and uses updated processing, but reviewers describe the upgrade as modest. A heavily discounted C4 is often the better-value purchase; a small price gap favours the C5.

Is the LG C5 good in a bright room?


It is brighter than older C-series OLEDs, but reflections remain a weakness. Daytime television and bright scenes can look good, while dark films may show windows and lamps clearly. A room with controllable lighting suits it better than a sunlit conservatory.

Does the LG C5 suffer from burn-in?


Permanent image retention is possible, but varied normal viewing presents a relatively low risk. Leave pixel-shift, logo-dimming and compensation features enabled. Buyers showing static interfaces for many hours every day should consider the risk more carefully.

Is the LG C5 good for PS5 and Xbox Series X?


Yes, gaming is one of its strongest areas. All four HDMI ports support modern HDMI 2.1 features, including 4K at 120Hz, VRR and ALLM. Dolby Vision gaming support is particularly useful for compatible Xbox titles.

Can the LG C5 run 4K at 144Hz?


Yes, with a compatible PC and graphics card. Current consoles top out at 4K 120Hz, while a suitable PC can use the higher 144Hz mode. Cable quality and graphics settings still matter.

Does the LG C5 support Dolby Vision?


Yes. The C5 supports Dolby Vision, HDR10 and HLG. It does not support Samsung’s HDR10+ format, although standard HDR10 remains available for that content.

Does the LG C5 have Freeview Play?


UK versions support Freeview Play and the main UK catch-up services. App availability can change, so check the current listing for any specific service that is essential to you.

Is a soundbar needed with the LG C5?


Not for basic television, but it is strongly recommended for films and games. Dialogue is usable from the built-in system, while bass, scale and effects benefit substantially from an external soundbar or AV system.

Can the LG C5 be wall mounted?


Yes. Use a bracket rated for the television’s VESA pattern and weight. A 65-inch OLED panel is fragile and should be lifted by two people without pressing on the screen surface.

How far should you sit from a 65-inch LG C5?


Roughly 2 to 2.7 metres suits many viewers. Film fans may prefer the closer end for a more immersive image, while mixed broadcast viewing may feel more comfortable slightly farther away. Personal eyesight and room layout matter.

Does the LG C5 have four HDMI 2.1 ports?


Yes. All four ports support HDMI 2.1 gaming features, with one also serving as the eARC connection for a soundbar or AV receiver.

Is the LG C5 better than the Samsung S90F?


Neither is universally better. The Samsung can offer brighter, more saturated QD-OLED colour, while the LG supports Dolby Vision and has a particularly complete gaming interface. Price, room brightness and film-format preference should decide.

Does the LG C5 upscale normal HD television well?


It handles good HD sources well, but poor broadcasts remain visibly compressed on a 65-inch screen. The Alpha 9 processor can clean and sharpen lower-resolution material, but it cannot recreate detail that was never present. Some owners prefer Sony processing for low-quality television sources.

What picture mode should be used on the LG C5?


Cinema, Filmmaker Mode or ISF-style modes are sensible starting points for films. Game Optimiser should be used for gaming, and Standard or a calibrated daytime mode may suit bright television viewing. Avoid assuming the most vivid preset is the most accurate.

How long should an LG OLED TV last?


There is no single guaranteed lifespan beyond the warranty terms. Modern OLED panels are designed for years of ordinary use, but brightness settings, static content, heat and daily hours all affect ageing. Currys currently advertises a five-year guarantee on this model; check exactly what that guarantee covers before purchase.


Checks worth making before ordering



  • Check the model number: make sure the basket shows OLED65C54LA rather than an older C- or G-series television.

  • Assess reflections: note windows and lamps that will sit directly opposite the screen.

  • Measure the furniture: confirm the stand width, television width and room for a soundbar.

  • Plan the lift: arrange two adults for unpacking and positioning the fragile 65-inch panel.

  • Price the full setup: include a soundbar, wall bracket, installation and suitable HDMI cables where required.

  • Compare the C4: check whether the older model is substantially cheaper before paying for the C5.

  • Inspect normal content: look for distracting panel defects during the retailer return period without obsessing over artificial test slides.



Our buying view


The LG C5 is easy to recommend because it avoids obvious gaps. Films benefit from true OLED black, gaming support is among the most complete available, streaming is straightforward and the 65-inch size delivers a convincing cinema-like image without entering specialist projector territory.

Its weaknesses are situational rather than hidden. Reflections matter in the wrong room, built-in sound underserves the picture and bargain C4 stock can make the C5 look expensive. Get the room and price right, though, and this remains one of the most balanced premium televisions a mixed-use household can buy.
