Samsung Neo QLED QN70F / QN74F / QN77F vs TCL C7K / QM7K 55"-85"

QN70F is a television that can positively surprise when it comes to brightness. In ideal testing conditions, it reaches even 800 nits, which – for this price range – is a really solid value. Of course, that’s a result from test patterns, so we decided to check how it performs in practice, on real films. Here, the television somewhat tempers its capabilities. In most of the tested scenes – e.g. in "The Meg" – the actual HDR brightness remained around 500 nits. That’s still a decent result, allowing you to enjoy HDR effects, although it’s far from perfection. On the other hand, we have a QLED screen with a quantum dot layer, which means very good colour reproduction capabilities. Colours are vivid and saturated. QN70F covers about 94% of the DCI-P3 colour space, and in the wider BT.2020 palette, it exceeds 75%, so in this respect, there’s nothing to be ashamed of.

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.

We tested the QN70F in the best default picture mode, which is Filmmaker Mode. And it must be admitted that in this particular test unit, the factory settings performed quite well. The picture was calm, natural, and despite slight deviations – pleasant to watch. The biggest error was a slight dominance of red in the white balance, which caused a slight pinkish tint over the entire scene. However, it wasn't a glaring flaw – rather subtle and only noticeable when directly compared to a properly calibrated screen. A slightly bigger issue arose in the brightness characteristics. The TV tends to lower the brightness of parts of the image that should be displayed brighter. As a result, some details can appear slightly dimmed – they don't completely disappear, but they don't stand out as clearly as they should. Nonetheless, as for a TV in this range and in these settings – we consider the result a good starting point for further calibration.

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…

After calibration, the QN70F shows that it can offer a really high level of colour reproduction. It has managed to nearly perfectly balance the white point, and the values in the Color Checker test dropped below level 3 – that is, below the threshold at which the average eye can notice differences. The image looks natural, and the colours are faithfully reproduced, without excessive saturation or the coolness known from factory settings. It must be acknowledged that Samsung provides very extensive calibration options – not only for enthusiasts but also for professionals. The QN70F takes advantage of this potential and, after appropriate settings, can come close to significantly more expensive models in terms of colour accuracy. The only thing that could still be picked on is the brightness characteristic. There is still a tendency to brighten the smallest sections of the image – particularly those that should remain darker. However, this is a design feature of this model, not a calibration error. Despite this, the final result definitely deserves recognition.

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.

Samsung QN70F offers a distortion reduction feature that improves the smoothness of tonal transitions. In "Standard" mode, it works quite well – smoothing out problematic transitions without significantly interfering with the structure of the image. Film grain is partially removed, but details like texture and skin structure remain visible. "High" mode operates much more aggressively. The smoothing is stronger, but at the cost of a noticeable loss of detail. Therefore, in practice, we recommend sticking with the "Standard" setting or turning off this feature altogether. The improvement in gradation may be less spectacular, but the image retains more naturalness.

When it comes to upscaling low-quality content, the QN70F performs very well. Tests with lower resolution images went really well. Despite some slight aliasing of contours, everything looks clean and clear, even if the original content was very poor quality. It's just a pity that the television has an overscan issue that cannot be completely turned off. As a result, images with very low resolution may be slightly cropped, which is mainly noticeable on subtitles or the interface.

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.

The QN70F is a television with a refresh rate of 144 Hz, which in itself places it among the best when it comes to image smoothness. Whether we're watching fast-paced sports broadcasts or gaming on a console – the picture looks fantastic. There's no sense of stuttering, clipping, or the typical "judder" seen in lower-end models during fast motion. Samsung also allows you to adjust the smoothness to your own preferences. In the picture clarity settings, we find options such as motion blur reduction and judder reduction – each of which can be adjusted independently. This is especially useful when we are watching content with a lower frame rate and want to give it a smoother, more cinematic feel – or conversely, maintain the natural filmic "feel" of 24 frames.

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.

Samsung QN70F is a really solid choice for gamers. It features four HDMI 2.1 ports with full bandwidth of 48 Gbps, which means full support for gaming in 4K at a refresh rate of 144 Hz. Additionally, it comes with all the essential features we expect today: automatic game mode (ALLM), variable refresh rate (VRR), and a very well-designed, intuitive Game Bar with information on the mode, resolution, and frame rate. The Game Motion Plus feature is also noteworthy, allowing artificial frames to be added to games running at 60 fps or less. It works surprisingly well and improves gameplay smoothness without much delay in many titles – especially those where consoles struggle to maintain a stable frame rate.

[UPDATE] We have updated our Samsung TV tests for the 2025 model year due to the release of software version 1131, which restored the crucial gaming feature HGiG.

Unfortunately, there are also some pitfalls. The lack of support for Dolby Vision mode is not surprising – it’s a standard with Samsung. But the absence of the HGiG feature is much more disappointing. What’s worse, it was removed by a software update, leaving users who previously benefited from it quite shocked. Without HGiG, it’s impossible to manually set the maximum HDR brightness from the console, which results in some games appearing slightly overexposed – especially if the TV misinterprets the tonal range. Why has Samsung, a brand that has set standards in gaming features for years, decided to take such a step? It’s hard to say. At the time of writing the review, the tested TV was operating on software version 1110 – and to be honest, if you’re relying on full support for gamers, it’s better to temporarily hold off on updates.

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.
