TCL C7K / QM7K 55"-85" vs Philips MLED920 / MLED910

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.

Philips MLED920 in our measurements in static tests even reached around 900 nits, which for a mid-range model is quite an impressive result. In practice, this translates to a lot of satisfaction during viewing – in scenes rich in bright light, such as the first, third, or fifth test patterns, the screen was able to generate around 700 nits, which is sufficient to feel the real "HDR effect". However, it cannot be denied that the limited number of backlight zones and the typical mini-LED compromises in dimming algorithms reveal their flaws in more demanding scenes. In sequences with small light sources – like the moon or a scene from the film Sicario 2 – the television clearly prioritises maintaining deeper blacks at the expense of the brightness of these small elements. For most viewers, this is still a reasonable compromise, as the dark background looks much better, although it should be noted that the details themselves may not dazzle with intensity. The question of colours also leaves a bit to be desired. Although the employed PFS filter (the equivalent of quantum dots known from QLEDs) does its job and the colours appear quite vibrant, the coverage of the DCI-P3 colour space reaches "only" 90%. In everyday viewing, this will be sufficient, but in extremely colourful productions – like the latest Disney animations – one can notice that some tones are not as vivid as they could be in other constructions.

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…

Like every Philips TV we've tested, the MLED920 was primarily assessed in Filmmaker mode – the so-called "most honest" mode, designed for films and to faithfully convey the intentions of the creators. Indeed, in terms of colour accuracy, it performs best among all the modes available on the TV, but it is not without flaws. The first thing that stands out is the white balance. The image has a slight tendency towards purple-pink tones, giving it a somewhat unnatural character. However, an even bigger problem turned out to be what we mentioned earlier – image clipping. Just looking at the gamma or EOTF charts reveals that the line deviates significantly from the norm, dropping below a value of 1.8. In practice, this means "bleeding" of the brightest whites, where the image becomes almost milky. Fortunately, most of these issues can be corrected – the MLED920 responds to calibration, and with a few adjustments, image quality can be significantly improved.

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.

After calibration, we managed to largely tame the white balance – to the extent that the average viewer will not be able to detect colour inaccuracies. The characteristic pink-purple glow that previously disrupted the naturalness of the image has also disappeared. The colour palette has been organised, and the colours appear more cohesive and neutral. The gamma in SDR content looks really good after calibration – there’s no sign of the earlier “bleeding” effect in bright scenes. The image has become more contrasty and free from the milky effect that previously severely affected the viewing experience. In the case of HDR content, the improvement is also noticeable, although here it is still evident that the television goes “its own way”. The EOTF curve cannot be fully adjusted, as Philips simply does not offer tools for precise control of this parameter in its settings. In many films, the television still exposes the image “in its own way”. Despite these limitations, calibration has brought a lot of good – the majority of colour inaccuracies have been minimised and the overall image balance has significantly improved. However, one must remember that certain barriers arise from the very hardware construction and simply cannot be overcome.

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 manufacturer has equipped this model with several features that improve signal quality, and although we usually approach such “enhancers” with caution, here they prove to be really helpful. The key option is called “distortion reduction” – it works best at a medium level because, on one hand, it effectively smooths out unwanted steps and colour transitions, and on the other, it doesn’t excessively cut details, meaning the image still looks natural.

It’s a bit worse when it comes to upscaling. Lower quality materials – such as the test video with the model – appeared soft and lacking sharpness. Of course, it can be partially adjusted with the sharpness slider in the menu, but the result still falls short compared to what competitors offer at a similar price. Philips still needs to work on this aspect because, in light of the successful improvement of tonal transitions, the upscaling simply comes off weak.

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.

Philips MLED920 features a 144 Hz panel, which immediately suggests that we shouldn’t complain about motion smoothness. And indeed – for a VA panel, the motion blur is relatively low here, and while you can sometimes notice slight issues on darker backgrounds, they’re not something that will catch the eye of most people during regular viewing.

A big plus is also the presence of a motion smoother called “Motion Style.” It allows you to adjust the smoothness to your own preferences – if someone prefers a more “theatrical,” almost television-like character of the image, they can increase the sliders, and if they want to maintain the natural “judders” of a cinematic frame, they just need to set lower values. This way, everyone can find a happy medium.

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.

For gamers, the Philips MLED920 is truly a complete tool. The manufacturer has taken care of everything that is now considered standard in televisions for consoles and PCs. It has ALLM, so the console automatically switches the screen to game mode, there’s VRR and a 144 Hz refresh rate that ensures smooth gameplay even in fast-paced titles. All key HDR formats are supported – including HGiG and Dolby Vision Gaming for Xbox – which means that regardless of what you’re playing and on which console, the television will be able to extract the maximum potential from the image. In everyday gaming, the Game Bar proves useful too – a relatively simple implementation by Philips, but a functional panel where you can quickly check image parameters, enable VRR, or adjust details without leaving the game. It’s not as elaborate as the competition, but it does its job without any complaints. And finally, something that sets Philips apart from the competition – Ambilight. The three-sided LED backlighting can make a huge impression in games, especially in the evening. It’s also a way to slightly 'expand' the screen and create a greater sense of immersion. And since coloured LEDs have recently become almost an essential element of a gamer’s room, the MLED920 fits perfectly into this trend.
