Our verdict

Samsung QN70F is quite a decent television from the mid-range segment. Its strongest point is definitely the smoothness of the picture – thanks to the 144 Hz panel, low input lag, and a plethora of gaming features, we have here a recipe for an almost perfect gaming screen. It also performs well for sports fans – the picture is fast, clear, and there are no tears. In terms of picture quality – it’s really not bad at all. The VA panel provides good blacks, brightness is above average, and colours look great after calibration. Samsung advertises the QN70F as Neo QLED, meaning Mini LED, and in a sense, you can view it that way – but only partially. The backlighting is edge-lit, so it is far from being a full-fledged Mini LED with local dimming. It’s a shame, as marketing has its influence, and the user may feel somewhat misled. Additionally, there are minor shortcomings – no USB recording, no DTS support. But despite everything, the QN70F leaves a really good impression. It may not be a “true” Mini LED, but for its price, it is a solid piece of television – especially for gamers and those who enjoy fast, dynamic content.

There are televisions that come for testing, and you immediately think: “oh, just another average one, probably like many others.” And basically… that’s true. The TCL C7K doesn’t try to dethrone OLEDs, nor does it shout from the box “revolution!” Yet, after a few days of testing, it’s hard not to think: “wow, this is really good equipment.” And that’s exactly what the C7K is. The biggest asset of the C7K is its decent picture at a reasonable price – MiniLED and quantum dots do their job here. The colours are vibrant, the brightness satisfactory, the contrast impressive, and with the right settings, you can truly enjoy viewing in the best quality. The second strong point is the smoothness of motion – both in sports and games. Support for HDMI 2.1, variable refresh rates, 144 Hz, and a whole host of other features make gaming on this TV a pure joy. Then there’s Google TV, which – despite some minor shortcomings – provides access to nearly an endless library of applications. Voice control, quick access to YouTube, Netflix, AirPlay support – it has everything you need for everyday use. Are there downsides? Of course. The Google TV system can have moments of “hesitation,” and MiniLED – being MiniLED – can stumble on very complex film scenes. But these are details. After all, the C7K is a mid-range model – and in this class, it performs simply excellently. So if you are looking for a reasonably priced, modern television with Google TV that looks good, works well, and plays quite decently without ruining your budget – the TCL C7K definitely deserves your attention.

Halo effect and black detail visibility:

The QN70F is equipped with a VA panel that offers a high native contrast – this is already a good starting point for black levels, especially during evening viewing. However, its capabilities do not theoretically end there. The television is branded as Neo QLED, which indicates the presence of Mini LED technology and a local dimming system. And indeed – the QN70F has this function. The problem is that we are not talking about classic local dimming with LEDs positioned directly behind the panel. Instead, edge lighting has been implemented with an overall dimming mechanism known as global dimming. The effect of this is that instead of selective brightness control in individual zones, the entire screen is slightly dimmed when a dark scene appears. In practice, this means that the contrast is average compared to Mini LED models that offer true local dimming. The black levels are not bad – thanks to the VA panel itself – but one cannot speak of precise light control like that provided by advanced systems with multiple zones. This raises the question: is the QN70F series really a Mini LED television, or just a marketing variation on the Q70 series? Looking at the technical aspects – it is hard to consider this model a full-fledged representative of this technology. But in everyday use, the black levels appear decent and for many people may be fully satisfactory.

The 50-inch TCL C7K that we tested surprised us right from the start – it’s the smallest model in the series, yet it comes equipped with a VA panel with MiniLED backlighting and – attention – as many as 336 dimming zones. For comparison: many significantly larger televisions from higher tiers would be eager to boast such a number. Here we have it in the 50-inch version. Sounds promising, doesn’t it? So how does this translate into real movie-watching experiences? In the vast majority of tested scenes – very well. The contrast was high enough that it reached even six-digit values in measurements, which practically means very deep blacks and well-separated highlights. In scenes from films like The Revenant or Oblivion, the effect was impressive, matching the best LCD screens in this class.

However, not everything went perfectly. Despite the impressive number of zones, managing them was not always exemplary. In more complex scenes, where small light sources or a high level of detail appeared, the television had issues with the so-called halo effect (a glowing halo around bright objects) or overly aggressive dimming of the image. In such situations, contrast could either collapse due to overexposure of certain zones or, conversely – details in bright areas disappeared because the zones suppressed the light too much. Nonetheless, it is worth noting that in the vast majority of scenes, the contrast was more than satisfactory. And taking into account the size of the television and the price, the final effect will satisfy not just average users.

The QN70F is a television that can pleasantly surprise when it comes to brightness. In ideal testing conditions, it reaches up to 800 nits, which – for this price range – is a really solid figure. Of course, this result comes from measurement charts, so we decided to check how it performs in practice, with real films. Here, the television somewhat tempers its capabilities. In most tested scenes – for example, in "The Meg" – the actual HDR brightness hovered around 500 nits. This is still a decent result, allowing for enjoyment of HDR effects, although it is far from perfect. On the other hand, we have a QLED screen with a layer of quantum dots, which means very good colour reproduction capabilities. The colours are vibrant and saturated. The 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 is nothing to be ashamed of.

TCL C7K is one of the brightest MiniLED televisions in its price range. Under the best testing conditions, the screen managed to achieve over 1200 nits, resulting in impressive, at times almost blindingly bright scenes. And most importantly – this is not just a theory based on measurements. In practice, the brightest parts of films can shine with true cinematic grandeur. Fans of home HDR cinema should be truly satisfied.

The impression is excellent, especially in scenes with large areas of brightness – a white sky, explosions, sun reflections, or magical sunsets can surprise with an intensity of light that is rarely seen in this price range.

However, it gets a bit worse when more challenging scenarios appear on the screen, as described when discussing contrast – that is, images full of details, with small, bright elements on a dark background. In such cases, the C7K often decides to preserve black levels at the expense of brightness. An example? Scenes from the films Sicario 2 or Life of Pi, where small light sources (like a distant lantern) can become less visible, and details in the lights are simply dimmed or blend into the background.

For many viewers, this may be an acceptable compromise – as we achieve deep black levels and a pleasing plasticity of the image. Nevertheless, it is worth being aware that the visibility of small details in bright areas is not this model's strongest suit. It is simply a technological limitation that still exists – even with over 300 zones.

Factory color reproduction

Factory Mode

After calibration

We tested the QN70F in its best default picture mode, which is Filmmaker Mode. I must admit that in this particular test unit, the factory settings performed quite well. The image was calm, natural, and despite minor deviations – pleasant to watch. The biggest flaw was a slight dominance of red in the white balance, which caused a slight pinkish hue across the entire scene. However, this was not a glaring defect – rather subtle and only noticeable when directly compared to a properly calibrated screen. A somewhat larger issue arose in the brightness characteristic. The television tends to underestimate the brightness of parts of the image that should be displayed more brightly. As a result, some details can appear slightly muted – not so much lost completely, but not resonating as clearly as they should. Nonetheless, as far as televisions in this category and in these settings are concerned – we consider the result a good starting point for further calibration.

A new feature in TCL televisions 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 considered to be the truest to 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 this mode does not guarantee perfection. The Filmmaker mode in the TCL C7K is not without its flaws. There can be criticism of the incorrect white balance, particularly a slight dominance of blue, which resulted in cool, somewhat 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 image was simply too bright, at times even blown out, which affected not only the texture of scenes but also the overall viewing experience. Some details were simply lost, and the entire image looked as if someone had slightly overcooked the brightness slider. As always, we decided to check what could be extracted from this after calibration. And that’s where it started to get really interesting…

Color reproduction after calibration

8.5/10

7.5/10

After calibration, the QN70F shows that it can offer a truly high level of colour reproduction. The white balance was nearly perfectly aligned, and the values in the Color Checker test dropped below level 3 – meaning below the threshold at which the average eye can perceive differences. The image looks natural, and the colours are faithfully rendered, without excessive saturation or the coolness known from factory settings. It must be admitted that Samsung provides very extensive calibration options – not only for enthusiasts but also for professionals. The QN70F takes advantage of this potential and, after proper adjustment, can come close to significantly more expensive models in terms of colour accuracy. The only thing that can still be nitpicked is the brightness characteristic. There is still a tendency to lighten the smallest areas 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 effect definitely deserves recognition.

After calibration, the TCL C7K showcased itself in a really good light, especially when it comes to SDR content. We managed to precisely tune the white balance, colour gamut, and brightness characteristics to the point that colour errors on the ColorChecker palette dropped below a value of 2. For the uninitiated – this is nearly a perfect result, which means that the image is very close to what the creators intended. Unfortunately, the situation was worse with 4K HDR content. Although we managed to gently stabilize the white balance and correct its previous errors, it was still evident that the television has certain "MiniLED traits," especially in brightness management. When we checked how the C7K handled the EOTF curve on actual film scenes, rather than just on synthetic test patterns, it turned out that the screen still tends to slightly brighten the entire image. This impacts 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 truly very good. After calibration, the C7K can display an image that can compete successfully with much more expensive models. Good colour tuning, natural skin tones, and pleasant brightness make movie sessions and everyday viewing of content more than satisfactory.

Smoothness of tonal transitions

8/10

8.6/10

In terms of the fluidity of tonal transitions, the QN70F performs really well. Gradients are smooth, and colours blend into each other without obvious thresholds or banding. Even in more difficult movie scenes – particularly those that are very dark – any possible imperfections are minimal and you really have to make an effort to notice them. In regular viewing, most users should not encounter any issues with colour merging. The image looks clean and coherent, without artificial smoothing or distortions. This is another aspect in which the QN70F pleasantly surprises.

The TCL C7K handles colour gradation very well – in most of the tested scenes, tonal transitions were smooth, and colours blended together without visible outlines or the artificial "blot" effect. In everyday use, it's hard to find anything to criticise – the picture looks natural, without annoying transitions or digital artifacts. Certain limitations only arise in very dark tones – particularly in a heavily muted grey palette, where the television may struggle to reproduce the ideal gradation. But this is absolutely understandable, as even many significantly more expensive models in this regard simply falter. Fortunately, these situations are rare and do not significantly impact the overall impression.

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

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

TCL C7K is equipped with a feature that, according to the manufacturer, is meant to smooth out unwanted colour transitions – a sort of rescue for less successful tonal shifts. It is called "Gradual Smoothing" and… well, it sounds ambitious, but in practice it works very poorly. Regardless of whether we set it to a low or high level, the difference is minimal. Worst of all, the feature can cut out elements from the picture that should be there. Fortunately, film grain remains untouched, so at least it doesn’t smooth everything indiscriminately, but still – it’s better to simply turn this option off.

When it comes to scaling lower resolution content, it is somewhat better. SD and HD materials look quite decent, although at times we had the impression that the image loses sharpness and becomes too soft – as if something took away its definition. Fortunately, with very low sources (e.g. 576p), there was no overscan effect, meaning the picture was not 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 top when it comes to image fluidity. Whether we are watching dynamic sports broadcasts or playing on a console – the picture looks very good. There is no sense of stuttering, choppiness, or the typical "tearing" associated with weaker models during fast motion. Samsung also allows you to adjust the fluidity to your own preferences. In the picture clarity settings, we find options such as blur reduction and judder reduction – each of which we can adjust independently. This is especially useful when watching content with a lower frame rate and wanting to give it a smoother, more theatrical character – or conversely, to maintain the natural cinematic "feel" of 24 frames.

The TCL C7K handles motion fluidity really very well. The matrix used in it offers a refresh rate of 144 Hz, which in itself suggests that this television is more than just a regular "60 Hz" panel. Furthermore – if we connect the C7K to a computer and set the resolution to Full HD. But we'll write more about this in the paragraph about gamers and PC collaboration. Returning to everyday use – both sports and films look very good here. Thanks to the fast panel and well-functioning motion smoothing, the C7K is great for watching matches, but also for movie screenings. In the menu, we find two sliders – motion blur reduction and flicker reduction – which allow us to adjust the fluidity effect to our own preferences. At lower settings, we get a more cinematic effect, with slight stuttering motion. At higher settings – the picture becomes more theatrical, fluid to the point of excess. Everyone has their own preferences – anyone can set it to their liking.

The Samsung QN70F is truly a solid choice for gamers. Here, we find as many as four HDMI 2.1 ports with full bandwidth of 48 Gbps, meaning full support for gaming in 4K at a refresh rate of 144 Hz. Additionally, it includes all the essential features we expect today: automatic game mode (ALLM), variable refresh rate (VRR), and a very well-designed, intuitive Game Bar showing information about mode, resolution, and frame rate.

Also noteworthy is the Game Motion Plus feature, which allows artificial frames to be added to games running at 60 fps or less. This works surprisingly well and in many titles – particularly those where consoles struggle to maintain a stable framerate – it improves the fluidity of gameplay without significant delay.

Unfortunately, there are some drawbacks. The lack of support for Dolby Vision mode is not surprising – it’s a standard with Samsung. However, the absence of the HGiG feature is much more disappointing. Worse still, it was removed with a software update, which may leave users who previously relied on it quite puzzled. Without HGiG, it is impossible to manually set the maximum HDR brightness from the console, resulting in some games appearing slightly washed out – especially if the television misinterprets the tonal range. Why Samsung, a brand that has set standards for gaming features for years, decided to take such a step is hard to say. At the time of writing this review, the tested television was running on software version 1110 – and frankly, if you care about full support for gamers, it’s better to hold off on updates for the time being.

The TCL C7K is a television that on paper appears to be the dream equipment for gamers – and most importantly, it holds up in practice too. To start with good news: there are two full-bandwidth HDMI 2.1 ports, so we can easily connect both a console and a computer, taking advantage of all their capabilities. The panel itself supports a refresh rate of 144 Hz, which gives a significant advantage in dynamic games. There is also a complete set of gaming features: VRR (variable refresh rate), ALLM (automatic low-latency mode), and support for Dolby Vision in games. There is also the HGiG mode, which allows for HDR effects consistent with the creators' intentions. GameBar, an information bar for gamers. It works quickly, looks clear (like a Nintendo console👌), and shows what matters most: the current frame rate, VRR status, and even HDR parameters.

QN70F does not disappoint in terms of response time either. For 120 Hz materials, the input lag hovers around 8 ms, which can be considered a very good result – especially in the context of online competition or dynamic action games. The screen responds to the movements of the controller almost instantaneously, with no noticeable delay. As a result, the gameplay is smooth and comfortable, even in more demanding titles. In this category, Samsung still maintains a high standard, and it is hard to find anything that could raise objections.

When it comes to delays, the C7K gives no reason for complaints. In games at 120 Hz, input lag is around 10 ms, which means the television responds really quickly. And interestingly – even in Dolby Vision mode, the result is very similar, which is not always the standard. Good job, TCL. At 60 Hz, the lag does increase a bit, but that's completely normal and affects virtually every television with a refresh rate of 120Hz and above. The most important thing is that everything still runs smoothly and there’s no feeling that something is not responding to our actions.

Let's start with the best aspect of connecting the QN70F to a computer – gaming. A refresh rate of 144 Hz, support for G-Sync compatible VRR, and very low input lag create the perfect recipe for an almost ideal screen for PC gamers. In this role, the QN70F truly does not disappoint – games look smooth, responsiveness is at a very high level, and everything runs stably.

However, the performance regarding text work is somewhat lacking. At a resolution of 4K and a refresh rate of 144 Hz, there is a noticeable blurriness in the font contours – text may appear slightly smeared, with a slight “layering” of the contours. This is not a problem that undermines the usability of the QN70F as a monitor, but individuals planning to do office work or text editing on this screen should keep this in mind.

If we are going to connect the C7K to a computer – especially for gaming – there is definitely a lot to play for. We have 4K at 144 Hz, which already sounds great, but if we lower the resolution, the television can even display up to 280 Hz. In e-sports, where every fraction of a second counts, this really makes a difference. On top of that, there is support for G-Sync and FreeSync, so regardless of which graphics card we have – the image will be smooth, without any stuttering or tearing.

However, if we plan to place the C7K on a desk and use it like a monitor, it’s a bit less "rosy." Yes, it supports chroma 4:4:4, so fonts should be sharp, but with very dark letters, there is slight blurriness and dimming of the edges. This is not something that immediately stands out during gaming or watching, but when working with text – it can be distracting. In everyday use – it’s probably nothing to worry about, but if we plan to place a 50-inch screen a meter from our face, it’s worth keeping this in mind.

As for the VA panel, the viewing angles on the QN70F are typical – meaning rather average. The image quickly loses contrast and saturation when we start looking at the screen from a greater angle. Compared to IPS panels, it performs significantly worse. On the other hand – thanks to this panel, we gain better blacks and higher contrast when viewing straight on, which will be more important for many users than wide visibility from the sides.

There are no surprises here – the C7K has classic viewing angles for a VA panel. That is: sitting directly in front – it’s excellent. The colours look good, the contrast is strong, everything is in place. But just shifting slightly to the side and it starts to get worse – the image loses saturation, blacks turn grey, and the overall impression diminishes a bit. So, if we plan to watch together with a few people or have a sofa that takes up half the living room – it’s worth seating everyone a bit more centrally. You can watch from the side, but don’t expect miracles – it’s simply a characteristic of VA panels.

The QN70F handles a bright living room without any issues. The screen has a satin finish that effectively suppresses reflections, so there's no need to immediately draw the curtains to see anything. Even when there's plenty of light in the room – for example, with a window to the side – the picture still looks clear and vibrant. The brightness is also at a solid level. In SDR mode, the television averages around 500 nits, which is more than sufficient for daytime viewing. While it may not reach the levels of top models, in practice – for everyday television watching, sports, or YouTube – it performs very well.

Fortunately, the TCL C7K performs quite well in bright rooms. The applied panel has a satin finish that effectively suppresses reflections, which means we don't have to worry about lamp or window reflections even on sunny days. Importantly, the colours maintain their intensity and do not wash out, as can happen with weaker matte panels. In terms of brightness, the average for content like YouTube or regular television is slightly below 500 nits. This is not a record-breaking result – for example, the MQLED85 (C765) performs better in this regard. However, for everyday viewing during the day, it should work without major issues, provided we do not plan to place it opposite a south-facing window without curtains.

Television Features

The QN70F doesn't forget classic features that still matter to many users. On board, we find, among other things, picture-in-picture (PiP) mode, enabled by the presence of two tuners, teletext, and a "Sound Only" mode – perfect if we want to use the television like a radio. We can easily pair it with headphones or a soundbar via Bluetooth, and the remote control – despite the absence of a numeric keypad – works reliably, allowing us to operate other devices and additionally does not require us to aim at the screen. However, it should be noted that like all new Samsung models, we will not find USB recording functionality here. This is a system limitation that the brand clearly adheres to consistently.

Smart TV QN70F – Tizen

The Tizen system, developed by Samsung for years, is one of the most refined Smart TV interfaces. It is fast, intuitive, and feature-rich. The QN70F supports voice search (also in Polish), wireless screen mirroring from a phone (both via AirPlay and Miracast), as well as integration with watches and other devices in the Samsung ecosystem. All of this is connected by the SmartThings app, which allows you to control hardware, automate tasks, and connect devices in one network. (Not only Samsung brand devices). However, it is not perfect. Tizen is a closed system, so the selection of apps can be somewhat limited – especially in comparison to Google TV. All the major streaming services are in place, but if you use less popular services, it's worth checking before purchasing if they are available in the Samsung store.

SmartTV: GoogleTV

The greatest strength of the TCL C7K in everyday use is undoubtedly the Google TV system. Thanks to it, we have access to an almost endless library of applications, including some more niche ones that are often unavailable on other platforms. The built-in Google Assistant understands Polish, so we can easily ask what’s on TV, what the weather is like, and even issue a few voice commands to control the television. The presence of Chromecast and AirPlay, which work smoothly and make life easier, is also a plus.

User Functions

On the downside, the classic features are somewhat lacking. Of course, we have the basics – teletext, EPG, and the ability to connect headphones – but that’s about it. There is no USB recording feature or picture-in-picture (PiP) mode, which can still be found among competitors. It’s also worth remembering that Google TV in the TCL edition can sometimes have strangely translated parts of the menu or minor errors in the interface. These are not things that interfere with daily use, but those sensitive to details may notice them.

Samsung QN70F performs well with media playback – it easily runs photos, music, and videos in the most commonly used formats. During tests, it effortlessly opened JPG files, MP4, and subtitles in TXT format, so for most people, this will simply be sufficient. However, there were instances where a few files – despite having the correct extensions – would not play. It may be an issue with a specific version of the system, and the problem might disappear after future updates.

The built-in file player in the TCL C7K performs really very well. It supports most of the most popular audio and video formats, so if we want to quickly plug something in from a USB drive and play it – there should be no problem. Of course, as is usually the case, we can find some minor shortcomings – not every exotic codec will work (Apple's HEIC), not all subtitles will be perfectly synchronised (txt.). However, the biggest advantage of this television comes to the rescue, namely Google TV. Thanks to access to the Google Play store, we can easily install an alternative player, e.g. VLC, and then no files will be a concern for us.

The Samsung QN70F performs quite mediocrely in terms of sound, which shouldn't come as a surprise considering the exceptionally slim design of the television. The built-in speakers will manage perfectly well during everyday viewing of news or simpler content, but it's hard to talk about any depth or spaciousness of sound here. It's simply a compromise one has to accept when choosing an elegant and thin design over a bulkier casing with a better audio system.

To be honest, we didn’t expect much from the sound of the 50-inch version of the C7K model. Typically, in such sizes, it’s hard to get anything more than thin, flat sound. But here – a pleasant surprise. The audio proved to be really enjoyable, with good clarity and even a slightly discernible bass. This is probably related to TCL's new collaboration with the Bang & Olufsen brand, which is a novelty for 2025. Whether the C7K actually uses the original transducers from the Danish premium brand – we cannot confirm. But the end result still deserves a thumbs up. For a television without a soundbar – it sounds quite pleasant.
