TCL C7K / QM7K vs Hisense E7Q / E79Q

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.

The Hisense E7Q / E79Q is a television with average brightness, with a peak luminance level of around 350-380 nits. This is an absolute minimum that allows for HDR content to be viewed in a way that is close to the creators' intentions, although without a distinct "wow" effect. Synthetic test results on white screens have been confirmed in practice – in film scenes, the bright parts of the image are stable and quite uniform, but it's hard to speak of a true "light punch." In everyday use, for example, when watching Netflix or YouTube, the HDR effect is acceptable and is perfectly sufficient for most users. However, it must be stated clearly – this is not the level of top-end screens, and one should not expect that in this price range. Fortunately, the Hisense E7Q / E79Q has an advantage that allows it to gain quite a few points: it features a PFS LED QLED panel, utilising an additional phosphor layer that improves colour reproduction. The measured range of the DCI-P3 colour gamut is about 92%, which means that colours in most scenes are vibrant, well-saturated, and pleasant to the eye, particularly for this price bracket.

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…

In Filmmaker mode, the Hisense E7Q / E79Q television was truly impressive. After the first measurements, it became clear that the white balance was quite well tuned, with the only minor deviation being a slight tendency towards a purple tone, which we mentioned earlier. However, this did not significantly impact the overall character of the image – it remained coherent and pleasant to view. A much larger issue turned out to be the brightness characteristics (gamma) in SDR content and the EOTF curve in HDR films. The television noticeably brightened the image, flattening the contrast and diminishing its depth. Gamma values could drop from the reference 2.4 to around 1.9, making the image look as if it were covered with a thin, milky layer. Fortunately, this is a problem that can be relatively easily corrected through calibration.

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.

The biggest beneficiary of calibration in the case of the Hisense E7Q / E79Q was undoubtedly the SDR mode. It managed to achieve an almost perfect image – most errors in the Color Checker test dropped below a value of 3, and often even 2, which is an outstanding result for this class of equipment. The greatest improvement came from equalising the brightness characteristic (gamma), which meant the image no longer appeared washed out and regained its natural depth. In HDR content, it was also possible to improve colours and eliminate the purple tint 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 heavily, overemphasising some colours. This was also indicated by the EOTF curve, which was slightly above the reference values, suggesting these minor issues with excessive brightness. Despite this drawback and the design limitations that emerge with HDR content, the Hisense E7Q / E79Q gained quite a lot after calibration. In everyday use, the television presents a consistent, natural, and pleasant image, and the difference compared to the factory settings is enormous.

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.

In the case of the Hisense E7Q / E79Q, upscaling and digital image processing are not the strongest aspects of this television. It is evident that the manufacturer has opted more for simplicity rather than advanced image processing algorithms. The television does not offer any features to smooth tonal transitions or systems to improve image clarity, resulting in lower resolution materials looking simply very raw. On the screen, you can notice subtle compression edges that better processors in other models can effectively hide.

During the HD material tests, we noticed that the E7Q tries to artificially enhance detail, which sometimes works, and at other times has the opposite effect – the image becomes soft, slightly blurred, at times even “watery.” There is no aggressive sharpening that ruins naturalness, but there is also no finesse in the detail integration that better image converters offer.

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.

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

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.

Hisense E7Q / E79Q is truly a successful television for gamers, even though it does not support 4K signal at 120 Hz. The manufacturer, however, has ensured a set of features that until recently could only be found in more expensive models. There is ALLM, meaning automatic switching to low latency mode, allowing the television to activate game mode with very low input lag by itself. We also have VRR, functioning up to 60 Hz – while this may not look impressive on paper, in practice it is fully sufficient, as most games on consoles do not exceed this limit. All these settings can be quickly found in the Game Bar panel, a convenient menu created specifically for gamers. From this interface, one can change picture modes, enable a frame counter, or even... an on-screen reticle – humorously named "target point" in the Vidaa system, which is a result of awkward translation from the Chinese manufacturer.

Special praise should be given to the ability to play in 1080p at 120 Hz, which significantly improves the fluidity and responsiveness of the image. Therefore, 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 performs really well as a gaming television – especially for those who are not looking for perfection but rather a solid and fast screen for everyday gaming.
