LG OLED C6 review: Still the best OLED TV for most people

The latest evolution of LG’s best OLED TV series, the C6 is the benchmark model other big brand screens will likely be compared against in 2026.

Cosmetically it doesn’t look that different from what’s gone before, but behind the glass is significantly more processing power, courtesy of a shiny new Alpha 11 Gen 3 processor, which ushers in a commensurate increase in peak high dynamic range (HDR) brightness.

When it comes to hierarchy, the C6, as always, sits neatly between its extravagant G6 sibling, and the more accessible B6. If history is any guide then, of the three, this is the model most people will actually buy. So does it represent money well spent?

Price & Availability

As you might expect, the C6 comes in a variety of screen sizes: there are 42-, 48-, 55-, 65-, 77- and 83-inch versions, priced from £1,299 through to £4,799. This puts it in the upper mid-range of premium TVs. On review is the 65-inch, priced at £2,499.

Stateside, you’ll pay from $1,399 for the 42-inch through to $5,300 for the 83-inch. In Australia, meanwhile, you can expect that to equate to A$1,399 through to A$5,299 for comparable models.

However, there’s some additional devil in the details. The two largest models (distinguished by their 'C6H' suffix) use high-brightness Tandem OLED panels, the same panel used in the earlier flagship OLED G5 series, complete with Hyper Radiant Color Technology and Brightness Booster Pro. The remainder, including the 65-incher tested here, use an updated classic OLED 'EX' panel, with regular Brightness Booster technology.

Features & What's New?

While there’s some disparity in panel execution, the C6 line shares the same, generous feature count. Whatever you need your telly to do, a C6 will almost certainly do it.

Central to the user experience is webOS 2026, which is still one of the most comprehensive smart TV platforms available. All the major services are here – including Netflix, Prime Video, Disney+, Apple TV+, YouTube and others – alongside LG Channels, the brand’s own FAST (Free Advertising Streaming TV) smorgasbord. This now offers around 270 ‘channels’ in the UK, and the likelihood is you’ll find at least a few worth watching.

Perhaps disappointingly, LG has chosen not to support the Freely TV-over-IP service (read all about Freely here). LG tells me that’s because it sees its own ecosystem as the set’s de facto content hub, and views Freely as competition. We do get all the main UK catch-up apps – BBC iPlayer, ITVX, Channel 4, Channel 5 – but to my mind this is not really comparable to having live streaming channels to browse.

The webOS interface itself remains familiar: a rail-based layout with personalised recommendations, live TV listings and curated content hubs. You can also customise the home screen with widgets, such as a calendar, weather, or news, and even integrate fitness devices for guided workouts.

Voice control is built in, as are Google Cast and AirPlay. Accessibility is thoughtfully handled too, including simultaneous audio output to TV speakers and Bluetooth hearing aids. This will be a godsend for households where the audience has a mix of hearing requirements.

For gamers, the C6 is enviably well-equipped: the set boasts a 165Hz refresh rate for PC gamers, with Nvidia G-Sync and AMD FreeSync Premium (that's the VRR and ALLM boxes ticked). Console owners get their pick of the ports, with all four HDMI 2.1 inputs 4K 120Hz capable.

As a gaming screen it’s up to par. I measured input lag 13ms (1080/60), which is the same as last year’s C5 model.

Brain power also gets a boost. The set runs LG’s latest Alpha 11 Gen 3 AI processor, the same silicon found in its range-topping G6, as well as the latest Wallpaper TV and Micro RGB Evo MRGB 95.

LG claims substantial gains in processing power for the new chip, which translates to better upscaling and clear improvements in brightness and contrast.

Picture Quality

So has LG finally fumbled the ball when it comes to image quality? Has it ‘eck as like!

The C6 delivers punchy, hyper-sharp imagery with succulent colours and excellent control over light and shade – once you’ve disabled the default out-of-the-box power-saving mode, as clever as that might be.

Black levels are, as to be expected from an OLED panel, convincingly deep and inky, while near-black detail and shadow texture is clearly resolved, without smudging into greyness.

Picture modes include Cinema Home, Game Optimizer, Filmmaker Mode, Personalized, Vivid, Standard, plus a couple of ISF Expert presets for bright and dark room viewing.

There's also the option of selecting a self-adjusting AI Pro picture mode, selectable during setup, if you don't want to bother managing picture presets.

Ultimately, everything is a matter of taste, but watching The Mandalorian in 4K Dolby Vision (via Disney+), I found Cinema Home mode offered the best overall balance. Starfields retained their density and sparkle, with outstanding contrast and HDR snap.

The Standard picture mode ups brightness and overall impact, and generally looks fine with less cinematic fare, so that’s a solid option too.

Motion handling is well judged. Of the options offered, TruMotion’s Cinematic Movement is the least intrusive, at least in terms of movie material, removing judder without introducing that telltale soap-opera sheen.

Perhaps suprisingly, peak HDR brightness turns out to be the big story here. The C6 delivers a tangible uplift over its predecessor.

In Vivid mode, the set blasts past 2000 nits, as seen in very small highlights. Not that I’d advocate watching in Vivid for any great length of time. Cinema Home delivers a still impressive 1576 nits with a 5% window, dropping to 1123 nits on 10%.

Specular highlights – fireworks, reflections, metallic glints – display a convincing intensity, giving images more dimensionality.

This brightness bump comes largely from processing rather than brute-force panel changes. The Alpha 11’s expanded bit-depth handling (12-bit processing with a 13-bit output) enhances gradation and brightness precision.

Everyday TV, animation, and sports all look fabulous. You won’t want to turn it off.

Sound Quality

When it comes to audio, the C6 is more prosaic. It’s good enough, but is bass light. I measured very little happening below 100Hz. Playing back the Dolby Atmos ‘Amaze’ test clip, there's no thunderclap at all. Similarly, Dune Part Two unspools without any of its signature seismic bass moments.

This despite a dedicated 20W woofer buried in the set's case. The TV's official specification lists a 40W total in a 2.2 channel configuration. There is an AI Pro sound model, which offers a more upfront presentation, but I found it a rather thin, fatiguing listen.

There are ways to improve matters though. The C6 can be partnered with LG’s new wireless Sound Suite loudspeakers; the TV instigates a direct connection with the speakers, using them as rears in a spatial configuration. Or, of course, match it with one of the best soundbars for LG TVs.

Design & Usability

Cosmetically, the C6 is almost unchanged from its predecessor, and build quality remains excellent.

The wafer-thin panel has a slate-like rear finish, and sits on a central pedestal stand. This makes it easy to park on AV furniture, although the lack of any swivel is rather inconvenient.

Connectivity can be considered comprehensive. In addition to the quartet of HDMIs, there are a couple of USB ports, an optical digital audio output, Ethernet LAN, and both Wi-Fi and Bluetooth 5.3. The set is Auracast compatible and can also accommodate terrestrial and satellite aerial feeds.

The OLED C6 comes with the latest, thinnest Magic Remote control. I’ve never fully warmed to its on-screen cursor, but the customisable buttons and voice control are welcome. There’s no backlight here though.

The panel itself is conventionally glossy. It doesn’t have an anti-glare filter to repel ambient light sources, worth considering when placing the TV. Some will find this a benefit, though, as some home-cinema enthusiasts are staunchly against the anti-reflective panel for how it can affect black levels.

LG OLED C6 review: Verdict

The LG OLED C6 is a thoroughly impressive all-round OLED TV that wrings even more performance from a tried and tested recipe. LG’s boffins have managed to elevate picture performance, with higher peak brightness, extremely good shadow definition, and more intelligent processing.

If you want near-flagship picture quality without paying quite such a high-end price, then the C6 is exactly where you should be looking. It’s not flawless – audio could be further improved and the Freely snub is ill-judged – but the core C-series viewing experience remains a deeply satisfying, 5-star watch.

Also Consider

If OLED is your bag, compare and contrast the LG C6 with Panasonic’s Z90B, and the Samsung S90H. The former, in 65-inch guise, uses a Master OLED Pro OLED EX panel, and is capable of stunning image quality. Conversely, the Samsung S90H, boasts Glare‑Free anti‑reflection coating, helpful if ambient light is likey to be an issue where you watch.
