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

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.

Hisense E7Q / E79Q is a mid-brightness TV, with a peak luminance level of around 350-380 nits. This is the absolute minimum that allows viewing HDR content in a way that's close to the creators' intentions, though without a distinct "wow" effect. The results of synthetic tests on white test patterns were confirmed in practice – in movie scenes, the bright parts of the image are stable and fairly even, but it's hard to talk about a true "burst of light" here. In everyday use, such as when watching Netflix or YouTube, the HDR effect is acceptable and is more than sufficient for most users. However, it must be said clearly – this is not the level of top-end screens, and one shouldn't expect that at this price. Fortunately, the Hisense E7Q / E79Q has an advantage that allows it to score quite a few points: it's a QLED panel of the PFS LED type, using an additional phosphor layer that improves colour reproduction. The measured range of the DCI-P3 colour gamut is around 92%, which means that the colours in most scenes are vibrant, well-saturated, and pleasing to the eye, especially for this price bracket.

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 Filmmaker mode, the Hisense E7Q / E79Q television really managed to impress. After the first measurements, it turned out that the white balance was quite well tuned, with the only minor deviation being a slight tendency towards a purple hue, which we mentioned earlier. However, this did not significantly impact the overall character of the image – it remained cohesive and pleasant to view. A much bigger issue was the brightness characteristics (gamma) in SDR content and the EOTF curve in HDR films. The television clearly brightened the image, flattening contrast and taking away depth. Gamma values could drop from the reference 2.4 down to around 1.9, making the image look as though it was covered with a thin, milky layer. Fortunately, this is a problem that can be relatively easily corrected through 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.

The biggest beneficiary of calibration in the case of the Hisense E7Q / E79Q was undoubtedly the SDR mode. It managed to achieve almost perfect image quality – most of the errors in the Color Checker test dropped below a value of 3, and often even 2, which is a remarkable result for this class of equipment. The biggest improvement came from aligning the brightness characteristic (gamma), which made the image no longer look blown out and regained natural depth. In HDR content, it was also possible to improve the colours and eliminate the purple tint that we mentioned earlier, but errors in the Color Checker measurements were still noticeable. This is due to the fact that – as is often the case with Hisense televisions – the screen manipulates brightness quite strongly, overexposing some colours. This was also indicated by the EOTF curve, which was slightly above the reference values, suggesting these minor issues with excessive brightening. Despite this flaw and the construction limitations that arise with HDR content, the Hisense E7Q / E79Q gained quite a bit after calibration. In everyday use, the television presents a coherent, natural, and pleasant-to-the-eye image, and the difference compared to the factory settings is indeed huge.

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.

In the case of Hisense E7Q / E79Q, upscaling and digital image processing are not the strongest points of this television. It is evident that the manufacturer has opted for simplicity rather than advanced image processing algorithms. The television does not offer any features that smooth tonal transitions or systems that enhance image clarity, which makes lower resolution materials look quite raw. Subtle compression edges can be seen on the screen, which better processors in other models can effectively hide.

During the testing of HD materials, we noticed that the E7Q tries to artificially boost detail, which sometimes works and other times has the opposite effect – the image becomes soft, slightly blurred, and at times even "watery." There is no aggressive sharpening that ruins naturalness, but there is also a lack of finesse in detail integration that better image processors provide.

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.

Hisense E7Q / E79Q is a television with a 60 Hz screen, so sports fans in 4K may feel a slight disappointment – you simply won’t see such smooth images here as in more expensive models with higher refresh rates. Fortunately, when it comes to movies, the situation is much better. Cinematic materials recorded at 24 frames per second can be displayed here using a motion smoothing feature, allowing the user to adjust the picture to their own preferences – more cinematic with visible frames or smoother, in a theatrical style.

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.

Hisense E7Q / E79Q is a really good TV for gamers, even though it doesn’t support 4K signal at 120 Hz. However, the manufacturer has included a set of features that until recently could only be found in more expensive models. There's ALLM, which is auto-switching to low latency mode, allowing the TV to activate game mode with very low input lag automatically. We also have VRR, working up to 60 Hz – while this may not look impressive on paper, in practice it is fully sufficient, as most console games don’t exceed this limit anyway. All these settings can be quickly found in the Game Bar panel, a convenient menu created specifically for gamers. From this level, you can change picture modes, turn on a frame counter, or even… an on-screen crosshair – in the Vidaa system amusingly called a “target point,” which is the result of a clumsy translation from the Chinese manufacturer.

Special praise should go to the ability to play in 1080p at 120 Hz, which significantly improves the fluidity and responsiveness of the image. This means that if someone wants to play a few titles at a higher refresh rate, they can simply lower the resolution and enjoy much smoother motion. Despite the lack of 4K@120Hz, the Hisense E7Q / E79Q really performs well as a gaming TV – especially for those who aren’t looking for perfection but a solid and fast screen for everyday gaming.
