TCL C7K / QM7K 55"-85" vs Hisense E7Q PRO / E79Q PRO

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.

When it comes to HDR effect quality, the E7Q PRO unfortunately is not a television that impresses with brightness alone. In real film materials, we measured around 250–300 nits, which is simply not enough for HDR to look spectacular. There's a lack of that "spark" in bright details, flashes, and light effects, and in many HDR scenes, it can resemble more of a good SDR than true cinematic HDR. The silver lining in all this is the colours. We managed to confirm that the E7Q PRO is a PFS type television, which means it has an additional filter that improves colour gamut coverage. Because of this, even if the brightness doesn't deliver, the colours in HDR content can be properly saturated and pleasing to the eye, without the impression of a "washed-out" image.

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…

In terms of colour reproduction, we tested the Hisense E7Q Pro in Movie mode, which undoubtedly turned out to be the best built-in preset. It is this mode, unlike the Eco, Standard, or Dynamic settings, that offers the most natural colours straight out of the box. While no factory mode is completely free of flaws, the E7Q Pro deserves high praise for its colour rendition in standard SDR content. The colour palette has been very well tuned, and errors in the Color Checker tests often did not exceed a value of 3, which is an outstanding result rarely seen in such affordable TVs. The only drawback we noted in SDR is the tendency to darken certain elements of the image, as indicated by a slightly raised gamma curve. The TV performs slightly worse with colours in HDR mode. Here, colour errors become noticeable to the naked eye, mainly due to a deficiency of blue in the white balance. This causes the colours on screen to appear too warm, and for some viewers, they may seem almost "too cinematic." Of course, to improve these parameters, we proceeded with professional calibration.

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.

In the case of materials with standard dynamic range (SDR), our actions in Filmmaker mode turned out to be largely cosmetic 😉. We mainly focused on a subtle adjustment of the white balance and equalising the gamma curve, which allowed us to recover details in the darker areas of the image that previously tended to get lost. However, it's worth noting that the E7Q Pro unit we tested happened to be exceptionally well-made from the factory. We remind you that these parameters depend on the specific unit – with mass production, factory calibration can be random, so your unit may require slightly different adjustments. The biggest beneficiary of professional calibration was undoubtedly HDR mode. This is where we did the most work, which brought spectacular results. We successfully tamed the excessive warmth of the image, caused by a factory shortfall in blue colour. After calibration, colour errors were reduced to a significantly lower level, which will certainly please those watching a lot of streaming content in HDR format, expecting faithful reproduction.

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.

When it comes to upscaling and digital image processing, the E7Q PRO deserves praise. The scaling performs really well here and doesn't fall dramatically short of much more expensive, advanced TVs. Lower quality materials can look clear and reasonable, without the impression that the image is artificially "overdrawn." The smoothing function, however, presents a bit worse. Yes, it can be effective and improve tonal transitions in low-quality materials, but at the same time, it can introduce unwanted effects. Sometimes it removes film grain or adds unwanted artifacts, giving the image a more "digital" character. Therefore, we mainly recommend it to those who prefer a smoother, less cinematic image style.

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.

In the category of motion blur and fluidity, the E7Q PRO has one very strong argument. At this price, Hisense has added a 120 Hz panel, and in PC mode, it can even operate at 144 Hz. This immediately provides greater possibilities in motion settings, as more options for smoothing the image appear in the menu. Among other things, we have frame interpolation options, allowing us to adjust the fluidity for sports or movies, depending on whether we prefer a more cinematic character or a "theatrical" smoothness.

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.

E7Q PRO is a phenomenal screen for gamers. Besides the typical "issue" with Hisense, which is the lack of support for the HGiG format due to constantly active tone mapping, we get practically everything one could expect from a TV that is supposed to have a gaming tag. There are two HDMI 2.1 ports, along with a full set of key features. We have variable refresh rate, automatic switching to game mode, and support for 4K at 120 Hz. On top of that, all the important settings are at hand in the clear Game Bar. This tool not only looks modern, but it also has a typically "gaming" edge and actually makes life easier while gaming.
