Samsung Q7F vs TCL C7K / QM7K 55"-85"

Unfortunately, the Samsung Q7F is not one of the bright televisions, which directly impacts the quality of HDR films. The peak brightness of the panel is only around 250 nits, which is definitely insufficient for claiming a true cinematic experience. In practice, the HDR content does not differ significantly from classic SDR, making it difficult to talk about any "wow effect" that usually accompanies us when watching such films. During testing of film scenes, the image simply looked dark, and the brightness almost always hovered around the aforementioned 250 nits. The worst performance came from shots with small, intensely glowing elements – the global dimming technique used reacted very aggressively in those cases, dimming the entire screen to maintain the black effect. However, it is worth noting the presence of a QLED coating that broadens the colour spectrum. For a budget QLED model, the Q7F performs quite decently here: the DCI-P3 colour gamut coverage is around 93%, and BT.2020 reaches 70%. This means that despite the low brightness, the colours can still look quite vivid and attractive.

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.

The reproduction of factory colours in the Samsung Q7F is definitely not one of its strong points. In Filmmaker mode, which theoretically should be closest to neutral, the white balance issue is immediately noticeable. There’s too much red on the screen, while blue is lacking. The effects are very easy to notice – white, instead of being neutral, takes on warm, almost slightly orange tones. In the long run, this makes the entire image appear a bit unnatural, while bright areas of the scene can seem unrealistic. The problems are even more evident in HDR content. The charts show that the TV has significant errors in the Color Checker palette, which results in visible inaccuracies in the real image. In practice, this means that colours are not presented as they should be. The Q7F also heavily manipulates brightness; darker elements are overly boosted, causing them to lose their cinematic feel, while bright parts can be dimmed. This makes the image seem flattened, and contrast, instead of helping to bring out details, only highlights its own limitations. In HDR materials, this is particularly frustrating because every detail matters. In scenes where a subtle play of light and shadow should be felt, the Q7F either overdoes the lighting or, conversely, suppresses elements that should attract the eye. This causes the image to lose its depth, and instead of cinematic realism, we have a rather simplified effect.

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 professional calibration, we managed to bring the Q7F to order – at least in terms of SDR content. The image in this mode looks really good: the white balance has been set correctly, the colours appear natural, and the errors in the colour palette have dropped to levels practically invisible to the eye. Gamma behaves exemplary, and the only minor flaw remains a slight lightening of smaller elements, which stems from the lack of local dimming. For everyday watching of television or films in standard quality, the Q7F performs surprisingly well.

It was significantly more challenging to tame HDR content. Despite adjusting the white balance, the television still heavily manipulates brightness, causing scenes to appear unnatural – what was meant to be subtly darker can sometimes be overly bright, and the bright parts of the image can occasionally be dimmed. The final effect is better than in factory settings, but it’s clear that the construction limitations of the Q7F do not allow for fully utilising the potential of HDR materials.

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.

Upscaling and digital image processing in the Q7F is a bit of a rollercoaster. On one hand, we have really nice upscaling – weaker sources look better than you might expect. The image becomes clearer, sharper, and even older films or free-to-air TV hold up well. Samsung has been strong in this area for years, and the Q7F confirms that. On the other hand… things start to get tricky. The TV has a problem with overscan – part of the image is simply cut off, and it doesn't look very elegant. Additionally, we were let down by a feature called "noise reduction," which should improve the smoothness of tonal transitions in weaker materials. In other Samsungs, it works relatively well, but here it practically makes no difference – the banding in gradients is still there. It's a bit of a shame because we expected more from a model that is aimed at users looking for a display for SDR content.

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.

Motion blur and motion fluidity in the Q7F is probably the most budget-friendly aspect of this television. The 60 Hz panel makes the motion blur quite noticeable, especially in dynamic scenes, and it's rather hard to consider this model as equipment designed for watching sports or playing fast-paced games. In tests with the little green man, there was a long trail, similarly, the ball in a football match would leave behind streaks.

On the positive side, the presence of motion smoothing is worth noting. In films, it really makes a difference – especially since most materials are recorded in 24 frames. Here we can decide whether we prefer a more "cinematic" image, with a slight judder typically found in cinema, or a smoother, more “TV-like” one. This actually works quite well and helps improve the viewing comfort for series or movies.

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.

The features for gamers on the Samsung Q7F is a topic that stirs up quite a few mixed emotions. On one hand – no reasonable person was expecting miracles here, after all, it’s a 60 Hz television and it was clear from the get-go that this wouldn’t be equipment to squeeze the maximum from a console or PC. On the other hand, since the manufacturer promised specific solutions in promotional materials, it is only natural that we wanted to see them in practice. At the start, it’s looking pretty good. The automatic game mode (ALLM) works, so there’s no need to manually fiddle with the settings; the console switches the TV to low latency mode by itself. Plus, we have the Game Bar, which looks impressive and allows you to check a few basic parameters without leaving the game. And this is where the good news ends.

The biggest problem with the Q7F is VRR, or rather its absence. Indeed, the appropriate icon appears in the menu, you can even see it in the Game Bar, but throughout the entire test, the function remained dead and could not be activated in any way. Even more disappointing is the matter of HGiG; this option was actually available in the beginning, but after a software update, it disappeared completely, which is just unprofessional. Therefore, the Q7F is only suitable for absolute basics. Sure, you can turn on the console, play calmer titles, and enjoy low input lag, but if someone is counting on more advanced features that the manufacturer promised, they will be disappointed. This is not a television one buys with gaming in mind, and it’s better to be aware of this before purchasing.

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.
