TCL C7K / QM7K vs Hisense E8Q

TCL C7K is one of the brightest MiniLED TVs in its price class. Under optimal testing conditions, the screen can achieve over 1200 nits, resulting in impressive, at times dazzlingly bright scenes. And most importantly – this isn’t just a theory from measurements. In practice, even the brightest moments in movies can shine with true cinematic grandeur. Home HDR cinema fans should be really pleased.

The impression is fantastic, 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 rarely appears in this price range.

However, things get a bit worse when more challenging scenarios appear on the screen, previously described in terms of contrast – that is, images full of details, with small bright elements on a dark background. In such cases, the C7K often opts to preserve black at the expense of brightness. An example? Scenes from movies like Sicario 2 or Life of Pi, where small light sources (like a distant lantern) may 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 blacks and pleasant image depth. Nevertheless, it’s important to recognise that the visibility of small details in bright areas is not this model's strong suit. It’s simply a technological limitation that still exists – even with over 300 zones.

Since the E8Q is a twin of the U7Q, it’s no surprise that the HDR effect quality is almost identical. On paper, it looks promising – a peak brightness of 800 nits can impress in many scenes. Moments like light flashes in “The Meg” or shots of the sun in “Life of Pi” can indeed create a “wow” effect. But the longer we watch, the more we notice the limitations. The problem arises when small, bright details need to be shown against a dark background. In such situations, the dimming algorithms try to protect the contrast, but in the process, they also dim what should shine the brightest. Instead of dazzling details, we get almost invisible points of light. This is typical for Mini-LED in this price segment and is not surprising – but it’s worth knowing that the HDR effect will not always be fully preserved. Fortunately, the colour reproduction provides reasons to be pleased. A coverage of the DCI-P3 palette of about 94% is a very good result, and the quantum dot layer used (more precisely, PFS) does its job – colours are saturated and vibrant, especially with 4K content.

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 the most faithful to the original vision of the creators and is often recommended by enthusiasts of quality visuals. 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 faults. There are issues with inaccurate white balance, particularly a slight blue tint that resulted in cool, somewhat greyish skin tones. But that wasn’t the biggest problem. The main complaint was excessive brightness exposure, which is clearly visible on gamma and EOTF charts. 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 just lost, and the entire image looked as if someone had overdone the brightness slider. As always, we decided to see what could be squeezed out of it after calibration. And this is where things started to get really interesting…

Testing the Hisense E8Q in Filmmaker mode, we were hoping for a potentially neutral picture resembling the director's vision. Unfortunately – although it doesn't look too bad on paper (the colour reproduction errors aren't significant), in practice the image feels somewhat unnatural. The reason? The blue colour is boosted too strongly and there is a deficiency of red in the white balance. The effect? Scenes appear cool, and the white seems slightly bluish. Alongside the U7Q model, we also noticed a specific approach to brightness management here. The brightness reproduction curve for HDR content (EOTF) shows that the TV can significantly dim small, bright elements on the screen to maintain contrast – but sometimes it goes too far. On the other hand, it can excessively brighten larger, very bright areas, which disrupts tonal balance. It's a compromise that may not suit everyone – especially if you want a potentially faithful picture straight out of the box.

After calibration, the TCL C7K showed 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 so that the colour errors on the ColorChecker palette fell 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, it was a different story with 4K HDR content. While we were able to slightly calm down the white balance and correct its earlier errors, it was still evident that the TV has some "MiniLED traits", particularly in brightness management. When we checked how the C7K handled the EOTF curve on real film scenes, rather than just on synthetic test patterns, it turned out that the screen still had a tendency to slightly brighten the entire image. This affects the overall experience – the black loses some depth, and the image becomes less contrasty than it should be. Despite these minor issues with 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 colour tuning, natural skin tones, and pleasant brightness make movie watching and everyday content viewing more than satisfactory.

Calibration of the Movie mode yielded really good results, especially regarding SDR content. The white balance was successfully adjusted, giving the image a natural look – it appeared almost reference-level. The colours were well-saturated, and the overall experience of the content improved significantly. Unfortunately, when we switched to HDR materials, the familiar issues from the U7Q model returned. The TV still likes to "do its own thing," as seen from the analysis of the EOTF brightness characteristics – despite calibration, the E8Q still darkened small details in the shadows, while brighter parts of the screen were sometimes excessively boosted. In practice, this means that in darker scenes, some of the smallest details could simply disappear. Although it's worth noting that the entire calibration process brought a lot of good, not everything can be bypassed – even with the use of professional tools. The E8Q can impress with its picture, but in HDR content, its construction limitations become apparent, and it's worth keeping this in mind.

TCL C7K has a feature that, according to the manufacturer, is meant to smooth out undesirable colour transitions – something like a rescue for less successful tonal shifts. 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. Worse still – the feature can cut out elements from the image that should remain. Fortunately, film grain remains untouched, so at least it doesn't smooth everything indiscriminately, but even so – it's better to simply 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 had the impression that the image loses sharpness and becomes too soft – as if something took 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 older materials of lower quality, gentle smoothing of tonal transitions often comes in handy. The Hisense E8Q, like the U7Q, has a "Smooth and Gradient Picture" feature, but unfortunately, its effectiveness leaves much to be desired. The "Low" setting is nearly invisible in operation, while higher settings blur details instead of improving transitions. The good news is that the feature does not compromise film grain, which means it does not degrade the structure of the image. On the positive side, scaling is commendable. The TV can reasonably convert older content to a higher resolution – without artificially accentuating contours or excessive sharpening. Although it doesn't match the best models in this category, it performs quite well for its class.

TCL C7K handles motion fluidity really well. The panel it uses offers a refresh rate of 144 Hz, which suggests that this TV is more than just a standard "60 Hz" panel. Furthermore, if we connect the C7K to a computer and set the resolution to Full HD. But we will write more about this in the paragraph on gamers and PC compatibility. Returning to everyday use – both sports and movies look very good here. Thanks to the fast panel and the well-functioning motion smoother, 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 – that allow you to adjust the fluidity effect to your own preferences. At lower settings, we get a more cinematic effect, with slight judder. At higher settings – the image becomes more theatrical, fluid to the point of excess. Whatever your preference – everyone can set it their own way.

Similar to the U7Q, the E8Q model is a fast television designed with dynamic content in mind. It supports a 144 Hz refresh rate at 4K resolution, and if for some reason someone is still gaming in Full HD – it can even reach 240 Hz. This is a significant advantage, especially for PC users looking for maximum smoothness. In everyday use, the television performs very well. The “Ultra Motion Smoothness” mode gives us two sliders, allowing you to set the picture to your preference – whether it's more cinematic with the film frame preserved or highly smoothed, almost “TV show-like.” It's good that the manufacturer provides a choice here, instead of imposing one style. On sports material, live broadcasts, or in games – motion looks clean and stable. Sure, it’s not at the OLED level, but for this price range, the E8Q does a really good job.

TCL C7K is a television that on paper looks like the perfect equipment for gamers – and most importantly, it performs well in practice too. Here's some good news: we have two full-bandwidth HDMI 2.1 ports, so we can easily connect both a console and a computer, using all their capabilities. The panel itself supports a refresh rate of 144 Hz, which provides a significant advantage in dynamic games. Additionally, it comes with a full set of gaming features: VRR (variable refresh rate), ALLM (automatic low latency mode), and support for Dolby Vision in games. There's also an HGiG mode that allows for HDR effects that align with the creators' intentions. GameBar, which is an information bar for gamers. It operates quickly, looks clear (like a Nintendo console👌), and shows what's most important: the current frame rate, VRR status, and even HDR parameters.

Hisense E8Q does not hide its gaming pedigree. Just the specifications reveal that we are dealing with a television that will perform excellently as a gaming screen. Variable Refresh Rate (VRR)? It's there. Automatic Game Mode switching (ALLM)? That's there too. Additionally, there's impressive refreshment – 120 Hz in 4K or even 240 Hz in Full HD. Such a set is rare in this price segment. Everything runs smoothly and without major surprises. The only missing element – similar to the U7Q – remains support for HGiG. It's a shame because this feature facilitates adjusting the brightness curve to the capabilities of the specific television, enhancing visual fidelity with the intentions of HDR game developers. Without it, manual tweaking of the settings is necessary, which does not always yield a satisfying result.
