TCL Q6C (65Q6C-UK) review

TCL has achieved phenomenal critical and commercial success over the past couple of years thanks to an (almost) unerring ability to deliver good picture and sound quality at prices so aggressive they’ve had rival brands quaking in their boots. And, on paper at least, the Q6C looks to keep the winning streak going.

After all, features such as Mini LED backlighting, local dimming and a Quantum Dot colour system all sound surprisingly close to the specs found in TCL’s What Hi-Fi? Award-winning C7K series – yet the Q6C costs significantly less.

We guess there must be a catch somewhere, but on TCL’s current form we wouldn’t be at all surprised if whatever catch we find really isn’t that big a deal.

Price

Normally, if you spend £650 on a 65-inch TV, you would expect to get… not very much. Not for the first time in recent years, though, TCL is here to rewrite the TV value rulebook.

The set in question this time is the Q6C, the 65-inch version of which usually only costs £649 yet manages to carry such features as 4K/144Hz gaming support, Google TV smarts, Quantum Dot colours and even a sophisticated Mini-LED backlight system with local dimming.

We’ve been around the block enough times to know that such specifications aren’t automatically a guarantee of great picture quality – but at the risk of showing our hand too early, in the Q6C’s case they really do add up to something pretty special for the money.

TCL also sells 55-, 75-, 85- and 98-inch Q6C models for £409, £819, £949 and £1499 respectively. These are all pretty remarkable prices for screens built on the same key specs as the 65-inch model, where the only major difference is the number of dimming zones (more for the bigger screens).

The Q6C’s main competition, really, is TCL’s own C7K step-up model, which costs £200 more at the time of writing.

TCL also sells a C6K model which, it says, is identical to the Q6C. However, further up the range, TCL's ‘C’ variants often have a different panel coating to their “identical” ‘Q’ counterparts. The fact that matte vs glossy coatings can make a significant difference to picture quality, and that we haven’t specifically tested the C6K, this review only applies 100 per cent to the Q6C.

Design

At first glance, the TCL Q6C looks like a chip off the old TCL block. A narrow black frame runs around the screen, boasting a reasonably premium finish, and the screen sits on a pair of simple arched blade-style feet. These angle out slightly, bringing more attention to themselves than they would otherwise, but this stance also helps the set feel pretty sturdy and wobble-free.

As you go about screwing on the feet in either of the provided wide or close position options, though, you can’t help but notice first that the set sticks out around the back quite a long way by today’s TV standards, and also that the screen is significantly lighter than TCL’s more premium sets.

Most folk don’t spend their lives looking at the back of their TV, though, and the rather lightweight and plasticky nature of its build quality isn’t something you really feel aware of once the TCL has been set in place.

The Q6C’s remote control apes the TV it partners by quite effectively disguising an essentially rather lightweight and plasticky build behind a cute brushed finish, a sleek, long, thin shape, and an ergonomic button layout. That button layout includes direct access buttons for Netflix, Prime Video, YouTube, Disney+ and TCL’s own collection of live-streaming ‘channels’.

Features

Despite its aggressive price, the Q6C is built around a native 4K screen with Mini LED backlighting and a local dimming system that works, in the case of the 65-inch model we’re testing, across 242 independently controlled zones. At this price, local dimming of any kind is a rarity, so getting 242 dimming zones is a real treat. That said, the not vastly more expensive C7K features more than a thousand dimming zones.

The Q6C produces its colours using Quantum Dots, with which TCL claims to cover 93 per cent of the DCI-P3 colour spectrum used for most HDR mastering. The HDR support extends to both the Dolby Vision and HDR10+ premium formats, with their extra scene-by-scene image information, as well as the core HDR10 and HLG formats.

The set is also IMAX Enhanced certified, meaning it’s been judged capable of doing justice to the special noise-limiting IMAX Enhanced mastering system used on a few 4K Blu-rays and a fair number of films (especially Marvel releases) on Disney+.

Impressively for its money, the Q6C also gets one of TCL’s new HVA panels. These introduce a variety of innovations, including a faster transient response for enhanced clarity; a new light-emitting chip claimed to deliver 50 per cent brightness and 10 per cent efficiency boosts over its predecessor; and a new condensed micro lens system over the LEDs, that apparently focuses light better for greater backlight uniformity, optical stability and halo control.

Smart features on the Q6C, as with most of TCL’s current TVs, are provided by the Google TV platform. Unlike most other brands that use Google TV, though, TCL has managed to get BBC iPlayer on board alongside the other key terrestrial UK broadcaster catch-up apps, and all of the main global streaming services. The only things you don’t get that some rival smart systems offer are Freeview Play and Freely.

Gamers are exceptionally well catered for by the Q6C. It supports 4K/144Hz (and the console-friendly 4K/120Hz) gaming, and can even increase the frame rate to 288Hz if you’re prepared to accept a drop from 4K to Full HD resolution. VRR is supported, too, including in the AMD FreeSync Premium Pro format, and there’s even support for Superwide aspect ratios if you’re playing a PC game that supports them.

A special gaming menu becomes available when the TV knows you’re gaming, too, offering information on the incoming gaming signal as well as easy access to a selection of gaming aids that include a superimposed crosshair, the option to magnify part of the image to give, say, a mini-map more prominence, a couple of genre-specific picture presets, and an option to enhance shadow details in dark game sequences to make it easier to spot lurking enemies.

In a perfect world, all four of the Q6C’s HDMIs would support the full gamut of today’s gaming features rather than just two of them, but you don’t get perfect worlds on 65-inch TVs that cost this sort of money.

The Q6C’s sound system, finally, isn’t one of the Bang & Olufsen-designed systems found higher up TCL’s range. It’s still designed with another acclaimed audio industry brand, though, Onkyo, and still includes a couple of dedicated bass woofers on its rear panel to underpin the sound from its main stereo speakers. This sound system is capable of playing both Dolby Atmos and DTS Virtual:X sound formats.

Picture

While the Q6C doesn’t quite hit the giddy picture-quality heights of TCL’s C7K, it gets closer than the price gap would lead you to expect. This means that it also comfortably outguns pretty much every other 65-inch TV around at the same sort of price point – including Samsung’s recently reviewed U8000F.

The single most impressive thing about the Q6C's supposedly budget pictures is their black level performance. Once again, TCL’s particular combination of an HVA panel, local dimming, Mini LED lighting and local dimming processing results in excellent blacks in both dark scenes or dark picture areas and the black bars of widescreen content.

Hardly a hint of greyness slips into dark scenes, and backlight haloing around stand-out bright objects during dark shots is also remarkably well controlled for a 65-inch TV at the Q6C’s price point. We’ve seen 65-inch LCD TVs costing hundreds, even thousands, of pounds more than this TCL fail to deliver black tones so effectively.

As well as instantly giving the Q6C an outstanding foundation for the rest of its images to build on, its excellent black levels are also achieved without causing shadow details to become crushed out of the darkest areas. Dark scenes thus look as three-dimensional and immersive as bright ones, creating a sense of consistency that makes it easy to remain fully immersed in what you’re watching.

The Q6C’s remarkable freedom from the sort of hardware and/or processing issues that almost always to some extent plague the picture quality of other similarly affordable TVs continues across pretty much every other aspect of its picture performance, too. Images look crisp, clean and detailed enough to leave you in no doubt that you’re watching a native 4K screen, for starters – especially if you leave the set’s Precision Detail feature on (which you might as well, as it doesn’t seem to cause any negative side effects) and turn the Digital and regular Noise Reduction features off (at least when watching native 4K sources). Even the Q6C’s upscaling of HD sources is well above par for its level of the market.

Colours impress, too. There’s more vibrancy and lustre on tap than we usually see with such affordable TVs, yet at the same time, in most presets, the impressive vibrancy doesn’t look forced or unnatural. Skin tones look believable, there’s practically zero HDR colour striping, and subtle shading differences are rendered with enough finesse to ensure that even the most colourful images feel three-dimensional and realistic rather than cartoonish and flat. The nuance in the Q6C’s colours contributes in no small measure to the image's impressive sharpness, too.

The Q6C is not as bright as TCL’s step-up C7K model. It’s bright enough, though, to do arguably better justice to HDR images than any other similarly affordable 65-inch TV we’ve seen, combining good full-screen brightness with strong brightness peaks. All delivered alongside those excellent black levels we described earlier.

There are signs beyond its lower brightness that remind you that the Q6C is a step down from the C7K. While it’s faint, where backlight haloing does occasionally become noticeable, it spreads further beyond the bright highlight that’s causing it than it does with the C7K. That includes spreading very occasionally into the black bars of a movie if a really intensely bright object appears right next to them.

The very brightest highlights of bold HDR masters can also cause clipping, where subtle shading and colour details are lost in a sort of ‘white out’ effect, and skin tones can occasionally teeter on the edge of coarseness where they happen to catch bright sunlight, too – though they seldom if ever actually tip over into a distracting level of roughness.

Motion, once you’ve either turned the set’s motion processing off or left it on its low setting (to avoid unwanted over-smoothing or processing side effects), is marginally more prone to judder and blur with 24p movie sources than the C7K’s images are. But again, compared with the vast majority of rivals at its price point, the Q6C’s motion performance is actually pretty easy on the eye.

Colours can desaturate quite noticeably if you watch the screen from a steep angle of around 45 degrees or more, and blooming becomes slightly more noticeable. These problems are usually much more noticeable with budget VA LCD TVs, though, and from narrower angles.

To finish on the high note the Q6C’s pictures deserve, it’s a pretty stellar big-screen gaming display for its money. Graphics look crisp, bright and colourful, while the high frame rate support ensures gaming also feels fluid, smooth and responsive. The responsiveness is further bolstered by a measured input lag of just 13.1ms at 60Hz.

Sound

The Q6C’s Onkyo-designed sound system isn’t as ‘hi-fi’ in tone or as well-rounded as the B&O systems found higher up TCL’s current range. It’s not bad at all, though, for such an affordable TV.

Particularly surprising is the size of the soundstage it produces with DTS:X and, especially, Dolby Atmos mixes. Ambient effects and off-screen details appear well beyond the TV’s left, right and even top edges without the staging becoming incoherent or thin.

Dialogue seems to be coming from the screen rather than somewhere beneath or behind it, helping it sound impressively clear and clean. It still sounds contextualised enough, though, rather than bright or sharp.

Movie scores exist outside the scope of the main in-scene sound, just as they (usually) should, and sound effect detail levels are high enough to point to more quality in the speakers than you’ve any right to expect for this sort of money. Specific location details aren’t, to be clear, placed with the sort of accuracy you get with premium TV sound systems from the likes of Samsung, Philips and Sony, but the Q6C certainly does more with them than most similarly priced rivals.

There’s plenty of volume available, too, and while the sound density and power tend to level off during escalating action or horror scenes rather than continually expanding right to a scene’s climax, at least the sound doesn’t actively collapse under pressure.

Bass levels aren’t quite as rich and deep as we might have hoped, given the presence of two subwoofers on the set’s rear, which occasionally causes some high-pitched ambient effects to sound a little too dominant. Even the epic bass drops of Blade Runner 2049, though, don’t cause the bass speakers to seriously distort or drop out. In fact, the only distortion during Blade Runner 2049’s famous opening soundtrack dynamics comes from the treble, which causes a slight ‘buzzing fly’ effect when the speakers are under their greatest pressure.

The bottom line, though, is that, as with its pictures, the TCL Q6C’s sound is better than that of most, if not all, other TVs in its price class.

Verdict

If the Q6C cost twice as much as it does, we’d still class it as good. In fact, for a 65-inch TV at its price, it’s nothing short of ridiculous. If this is how TCL signs off its current range, we seriously can’t wait to see what the brand brings to the table next.
