Hisense E8Q vs TCL C7K / QM7K 55"-85"

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.

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.

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.

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…

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.

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 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 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.

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 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 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.

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.
