TCL C7K / QM7K 55"-85" vs LG QNED80A6A (VA)

In terms of brightness, the models ranging from 55 to 85 inches in the C7K series are truly impressive. Under optimal testing conditions, the 65-inch screen exceeded 1200 nits, which in practice means that the brightest scenes can dazzle with almost cinematic brilliance. These are not just dry figures from measurements – during screenings, bright skies, explosions, or reflections of light on water looked incredibly striking, often giving the impression that the television exceeds its price range. This is particularly effective in scenes with large areas of illumination, where the screen fills with intense brightness – for instance, in sun-drenched shots or during dynamic action sequences. Viewers looking for strong HDR will definitely be satisfied.

However, scenes that require precise backlight control – with tiny points of light against a dark background – prove to be more challenging. Here, the C7K, despite having over a thousand zones, can still dim brightness to maintain deep blacks. The effect is that in films like Sicario 2 or LIFE of Pi, some details, such as a distant lighthouse or single reflections, may appear less distinct or blend into the surroundings. This is a compromise inherent in MiniLED technology – it provides excellent image depth and blacks at a level not offered by standard LCDs, but this comes at the cost of limited visibility of the tiniest lights.

Let's talk now about how this TV shines. If you’re expecting dazzling light effects, we need to cool your enthusiasm. The LG QNED80A is a moderately bright television. Our measurements in most film scenes indicated values around 350-400 nits. That’s not enough to speak of a full, cinematic HDR experience and the feeling of that famous “high dynamic range” that flagship products offer. However, brightness is not everything. Although the QNED80A is not a “light monster,” it makes up for it in another key category: colours. This is where PFS technology comes into play, which LG marketers hide under the name QNED/NanoCell. With this trick, the TV offers a significantly wider colour palette than classic LCD constructions. In our tests, the coverage of the cinematic DCI-P3 palette reached a solid 93-94%. What does that mean for you? That even at lower brightness, when watching films in HDR, the colours will be vibrant, deep, and properly saturated. The image is not washed out but juicy, which is a significant advantage in this price range.

The new feature in TCL TVs for 2025 is the long-awaited Filmmaker mode, which until now has been found in most competing brands. This is great news, as this mode is regarded as the one that best represents the original vision of the creators and is often recommended by enthusiasts of good picture quality. Unfortunately – as is often the case – the mere presence of it does not guarantee perfection. The Filmmaker mode in the TCL C7K is not without its flaws. One could critique the incorrect white balance, particularly the slight dominance of blue, which caused cool, slightly greyish skin tones. But that was not the biggest issue. The main complaint was the excessive brightness exposure, which is clearly visible on the gamma and EOTF graphs. The picture was simply too bright, at times even blown out, which affected not only the richness of the scenes but also the overall viewing experience. Some details were simply lost, and the whole image looked as if someone had overdone the brightness slider a bit. As always – we decided to see what could be squeezed out of this after calibration. And that’s where it started to get really interesting…

It might seem that since the QNED80A is one model, it should offer the same picture regardless of the version. However, practice shows something completely different. Analyzing the variant with the VA panel in the best factory setting – that is, in Filmmaker Mode – we noticed a specific characteristic. This TV "out of the box" delivers a picture with a clear dominance of red and a deficiency of blue. Overall, it is very warm, almost hot. Many users might describe it as an "overly cinematic" picture, leaning towards sepia. Additionally, there is the issue of gamma curve – the TV has a tendency to slightly and artificially brighten scenes (gamma is too low), which causes the picture to lose some of its plasticity. The good news is that these are not panel errors, but merely software issues. As always in our tests, we performed professional calibration, which completely eliminated these drawbacks, restoring natural white balance and correct saturation.

After calibration, the TCL C7K put on a really good show, especially when it comes to SDR content. We managed to precisely tune the white balance, colour gamut, and brightness characteristics, resulting in colour errors on the ColorChecker palette dropping below a value of 2. For the uninitiated – this is an almost perfect score, meaning the image is very close to what the creators intended. Unfortunately, things didn’t look as good with 4K HDR content. While we managed to slightly calm down the white balance and correct its previous errors, it still shows that the TV has some "MiniLED traits," especially in brightness management. When we checked how the C7K handles the EOTF curve on actual movie scenes, rather than just synthetic test patterns, it turned out that the screen still has a tendency to slightly brighten the entire image. This affects the overall experience – blacks lose some depth, and the image becomes less contrasty than it should be. Despite these minor shortcomings in HDR content, the overall reception of materials – especially in SDR – is really very good. After calibration, the C7K can display an image that can successfully compete with much more expensive models. Good tuning of colours, natural skin tones, and pleasant brightness make movie sessions and everyday content viewing more than satisfying.

Was it worth spending time on calibration? Definitely yes. We managed to tame the initial, overly warm white balance and, most importantly, correct the gamma curve. The television stopped artificially brightening scenes, resulting in a deeper image. The biggest gains are visible in SDR content, such as when watching regular television, YouTube, or playing games without HDR. Here, the QNED80A shows its class – colour reproduction errors (DeltaE) fell below a value of 2. In technical terms, this means the errors are essentially invisible to the human eye. The image in everyday use has simply become very attractive, natural, and correct. The difficulties start with HDR content. Although we managed to improve the white balance, the EOTF curve (responsible for brightness at various levels) shows that the television still "interprets" the image in its own way. This results from the nature of the edge-lit backlighting with local dimming and the fact that LG gives the calibrator very little control over this parameter. In short: the television struggles to hide its hardware shortcomings, sometimes ignoring our commands. Nevertheless, the final image is significantly more accurate and pleasant to view than the factory settings, even if it still lacks a bit compared to studio perfection.

TCL C7K comes with a feature that, according to the manufacturer, aims to smooth out unwanted colour transitions – something like a rescue for less successful tonal changes. It's called "Gradual Smoothing" and... well, it sounds ambitious, but in practice, it works very poorly. Regardless of whether we set it to low or high, the difference is minimal. And worse still – the feature can cut out elements from the image that should remain. Fortunately, film grain is left untouched, so at least it doesn't smooth everything indiscriminately, but even so – it's best to just turn this option off.

When it comes to upscaling lower resolution content, it's already better. SD and HD materials look quite decent, although at times we felt that the image loses sharpness and becomes too soft – as if something had taken away its clarity. Fortunately, with very low sources (e.g. 576p), there was no overscan effect, meaning the image wasn't artificially cropped – everything fit on the screen as it should.

In this category, the QNED80A turns out to be a true "dark horse". It's a fantastic, affordable television for those who often watch lower quality content – for example, from traditional cable TV. The processor used here handles upscaling incredibly well, enhancing low resolutions to native 4K. The image after processing is natural, smooth, and most importantly – it is not overly jagged or artificially sharpened. In the menu, we also find a dedicated option for smoothing tonal transitions in low-quality content. This feature works really effectively, eliminating the annoying "banding" of colours during heavy video compression. However, we must remain vigilant. Remember, we are not dealing with the top-tier processor known from flagship OLED models. In more challenging scenes, the system might struggle and introduce minor artefacts or distortions. Nevertheless, it's definitely worth giving this feature a chance, because in the majority of cases, the quality improvement is visible to the naked eye.

TCL C7K handles motion smoothness really well. The panel used in it offers a refresh rate of 144 Hz, which alone suggests that this TV is more than just a regular "60 Hz" panel. Moreover, if we connect the C7K to a computer and set the resolution to Full HD. But we will write more about this in the section for gamers and PC compatibility. Returning to everyday use – both sports and movies look very good here. Thanks to the quick panel and the well-functioning motion smoothening feature, the C7K is great for watching matches as well as for movie screenings. In the menu, we find two sliders – blur reduction and flicker reduction – that allow adjusting the smoothness effect to personal preferences. At lower settings, we get a more cinematic effect, with a slight judder. At higher settings – the image becomes more theatrical, smoothly even to excess. Whatever your taste, everyone can set it to their liking.

We move on to a topic that may be crucial for many. Unfortunately, here we must point out the biggest "Achilles' heel" of the QNED80A model. This television is equipped with a panel that has a native refresh rate of 60Hz. There’s no denying it – at this price, we were hoping for more as we know that Chinese manufacturers can offer 120Hz screens for similar money. Due to this parameter, dynamic scenes in sports or fast-paced games are not the strongest point of this screen. Fortunately, LG has equipped the television with a proven smoothing system called TruMotion. It works quite well with film material (24 frames). We suggest playing around with the De-Judder slider – from our experience, setting it in the range of 2-4 provides the best compromise: motion becomes smoother, yet still looks natural, without the artificial "television theatre" effect.

TCL C7K is a TV that on paper looks like the dream gear for a gamer – and most importantly, it also holds up in practice. First, the good news: we have two HDMI 2.1 ports with full bandwidth, so we can easily connect both a console and a computer, making use of all their capabilities. The panel itself supports a refresh rate of 144 Hz, which gives a considerable advantage in fast-paced games. On top of that, it comes with a full suite of gaming features: VRR (variable refresh rate), ALLM (automatic low latency mode), and Dolby Vision support in games. There’s also an HGiG mode that provides an HDR effect aligned with the creators' intentions. GameBar, which is an information bar for gamers. It operates quickly, looks clear (like a Nintendo console👌), and displays what matters most: the current frame rate, VRR status, and even HDR parameters.

Since we've already established that the QNED80A is a 60Hz TV, we must say it straight: we won't be gaming here at 120 frames per second at any resolution. Does this disqualify the device in the eyes of gamers? Not necessarily, especially for those "casual" players. LG decided to sweeten this technical limitation by packing in quite a few useful features. We have support for VRR (Variable Refresh Rate) in the range of 48-60Hz and an automatic game mode ALLM, which instantly reduces input lag upon detecting a console. We manage all of this via a very convenient, purple Game Optimizer menu (Player Panel), which has become LG's hallmark. The manufacturer deserves big points for consistency regarding HDR. Although the TV does not support Dolby Vision in games on Xbox consoles, LG adds a well-implemented HGiG standard. Thanks to this, even on a screen with moderate brightness, playing in HDR is clear, and the details in shadows and highlights are accurately rendered, rather than being "clipped".
