TCL C7K / QM7K 55"-85" vs Haier M90E

In terms of brightness, the models from 55 to 85 inches in the C7K series are truly impressive. In the best testing conditions, the 65-inch screen achieved over 1200 nits, which practically means that the brightest scenes can dazzle with almost cinematic brilliance. These are not just dry numbers from measurements – during screenings, white skies, explosions, or light reflections on water looked incredibly striking, often giving the impression that the television exceeds its price class. This is particularly effective in scenes with a large area of illumination, where the screen is filled with intense brightness – such as in sun-drenched shots or during dynamic action sequences. Viewers looking for strong HDR will definitely be satisfied.

However, scenes requiring precise control of backlighting – with small points of light on a dark background – are 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 lantern or single reflections, can be less defined or blend in with the surroundings. This is a compromise inherent to MiniLED technology – it provides excellent image depth and blacks at a level that ordinary LCDs do not offer, but this comes at the cost of limited visibility of the smallest lights.

Haier M90E is a television that does not lack brightness. In most movie scenes, peak luminance exceeds 1000 nits, which gives the image a clear "kick" and high dynamics. In typical, bright HDR materials, this looks really good. However, one must take into account the previously mentioned dimming algorithm. In scenes that are not evenly flooded with light – for instance, when displaying individual stars in a black sky – high brightness underscores the imperfections of zone control. Instead of a precise light point, we often see a distinct halo effect around bright objects. Despite these shortcomings, the overall image presentation can be pleasing, largely thanks to color reproduction. The manufacturer applied a PFS phosphor coating, allowing for wide coverage of the color palette. In our measurements, the coverage of the DCI-P3 space was a solid 95%.

The novelty in TCL televisions for 2025 is the long-awaited Filmmaker mode, which until now could be found in most competitive brands. This is great news because this mode is considered the most faithful 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 free from flaws. One could point out the incorrect white balance, particularly the slight dominance of blue, which led to cool, somewhat grayish skin tones. But that was not the biggest problem. The main complaint was excessive brightness exposure, which is clearly visible in the gamma and EOTF charts. The image was simply too bright, at times almost blown out, which affected not only the depth of scenes but also the overall viewing experience. Some details were simply lost, and the whole image looked as if someone had slightly overdone the brightness slider. As always – we decided to see what could be squeezed out of this after calibration. And that’s when things started to get really interesting…

For the measurements, we chose the Film mode, which should ideally offer an image closest to the creators' intentions. Unfortunately, in the case of the M90E, its characteristics – besides the reduced brightness – do not differ much from the Dynamic mode. Both in SDR and HDR content, the image is clearly tinged with a cool blue hue. The white balance is heavily skewed towards blue, reminiscent of typical aggressive "store" settings. This results in an unnatural representation of skin tones and makes the image straining on the eyes during longer viewing sessions. The way brightness is managed also negatively affects color fidelity. The television struggles to maintain proper levels – small details are often too dim, while larger, bright areas of the image tend to get blown out. These deviations in the brightness curve, combined with the cool white balance, lead to very significant color reproduction errors (DeltaE) in the factory settings.

After calibration, the TCL C7K showed itself in a really good light, especially when it comes to SDR content. We managed to tune the white balance, color gamut, and brightness characteristics so precisely that color errors on the ColorChecker palette dropped below a value of 2. For the uninitiated – this is almost a perfect result, which means that the image is very close to what the creators intended. Unfortunately, it looked worse with 4K HDR content. Although we were able to slightly calm the white balance and correct its previous errors, it is still evident that the television has some "MiniLED traits," especially in brightness management. When we checked how the C7K handles the EOTF curve on actual film scenes, and not just on synthetic test patterns, it turned out that the screen still tends to slightly brighten the entire image. This affects the overall experience – black loses some depth, and the image becomes less contrastive 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 color tuning, natural skin tones, and pleasant brightness make movie sessions and everyday content viewing more than satisfactory.

Haier M90E clearly benefits from professional calibration, especially for SDR content. The TV menu offers a sufficient number of tools to effectively correct factory errors. We managed to "tame" the white balance and eliminate the dominant blue tint. We also adjusted, albeit to a lesser extent, the brightness curve (gamma), which allowed us to recover some details in the shadows that were too heavily muted from the factory. The end result for SDR is a picture that is definitely more natural and pleasant to watch. In the case of HDR mode, the success is only partial. Although it was possible to improve the white balance here as well, the color reproduction errors (Color Checker) remained at a high level. Analysis of the EOTF curve (responsible for brightness in HDR) points to the root of the problem: the TV imposes its own interpretation of the signal and does not provide tools to modify this curve. The source of the high errors is not the calibration itself, but the specifics of the device – aggressive and imprecise zone dimming interferes with measurements and is "stiffly" embedded in the characteristics of this model.

TCL C7K features a function that, according to the manufacturer, is supposed to smooth out unwanted color 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. Worse still – the function 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 still – it's better to just turn this option off.

When it comes to scaling lower-resolution content, it's already better. SD and HD materials look quite decent, although sometimes we felt 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 was not artificially cropped – everything fit on the screen as it should.

The evaluation of the image processor must be divided into two separate aspects, as the Haier M90E behaves inconsistently in this regard. The first issue is the upscaling itself, that is, scaling lower-resolution content to 4K. In this task, the television performs quite decently. The algorithms effectively enhance the detail, resulting in a final image that is relatively sharp, clear, and readable. In this respect, it's hard to have major complaints about the device.

The situation looks completely different with materials that have a high degree of compression, which we encounter in older recordings or on platforms like YouTube with lower bitrate. Here, the processor falters in smoothing tonal transitions and masking source imperfections. The television cannot hide compression blocks, resulting in a very harsh, "digital" character of the image. The lack of effective artifact reduction can effectively discourage viewing lower-quality content on this screen.

The TCL C7K handles motion fluency really well. The panel used in it offers a refresh rate of 144 Hz, which in itself suggests that this TV is something more than just an ordinary "60 Hz" panel. Moreover, if we connect the C7K to a computer and set the resolution to Full HD. But we'll write more about that in the paragraph about gamers and PC collaboration. Back to everyday use – both sports and movies look very good here. Thanks to the fast panel and well-functioning motion smoother, the C7K is great for watching matches, but also for movie screenings. In the menu, we find two sliders – blur reduction and flicker reduction – which allow you to tailor the smoothness effect to your own preferences. At lower settings, we get a more cinematic effect, with a slight stutter in motion. At higher settings – the image becomes more theatrical, smooth to the point of exaggeration. Everyone can set it up according to their liking.

The Haier M90E is equipped with a simple yet functional motion smoothing system (MEMC). In the settings menu, the user will find a three-level adjustment scale: low, medium, and high. This allows for tailoring the degree of interference with the image to personal preferences – from gentle smoothing of 24p movies to maximum fluidity (soap opera effect). The system operates stably and fulfills its purpose in typical applications.

TCL C7K is a television that on paper looks like the dream equipment for gamers – and most importantly, it holds up well in practice. First, the good news: we have two full-bandwidth HDMI 2.1 ports, so we can easily connect both a console and a computer, taking full advantage of 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 suite 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 consistent with the creators' intentions. GameBar, which is an informative bar for the gamer. It operates quickly, looks clear (like the Nintendo console👌), and shows what’s most important: the current frame count, VRR status, and even HDR parameters.

From a hardware perspective, the Haier M90E is a solid proposition. The TV is equipped with two full-bandwidth HDMI 2.1 ports, which ensures support for key technologies: VRR (variable refresh rate) and ALLM (automatic low-latency mode). A plus is also the correct implementation of the Dolby Vision mode for gaming, which maintains a relatively low input lag. Problems arise with software configuration. The biggest drawback is the forced, continuous dynamic tone mapping by the TV's processor. This prevents proper HDR calibration from the console using system panels (HGiG) – the TV ignores source settings and processes the image its own way. We also noted shortcomings in the interface: the M90E does not have a typical "Game Bar" (overlay with parameters), which is a standard among competitors. Cooperation with Xbox consoles at unusual parameters turned out to be problematic – the device has difficulty correctly displaying 1440p resolution at 120 Hz refresh rate. Despite the aforementioned shortcomings in the software, the Haier M90E remains a very attractive screen for gamers. The final impression is saved by a solid hardware base. Native panel refresh at 144 Hz and the presence of full-fledged HDMI 2.1 ports are advantages that are crucial in daily use. If we are looking for a TV that provides high fluidity and supports 4K signals, this model will fulfill its task.
