Sony Bravia 8 MK2 vs TCL C7K / QM7K 55"-85"

Thanks to the new QD-OLED panel, the Sony Bravia 8 II can achieve astronomically high brightness levels of around 2000 nits, translating to nearly reference quality in films and series recorded in HDR format. In test materials such as Life of Pi and Sicario 2, the effect is simply stunning – details in bright parts of the image remain perfectly visible, while night scenes captivate with depth and contrast. However, it's not perfect. Compared to the fiercest competitors, the Bravia 8 II shows a noticeable drop in brightness during full-screen, very bright scenes. When comparing peak luminance to 100% white brightness in HDR mode, the Bravia 8 II is even two or three times dimmer than the LG G5 or Samsung S95F models. This was particularly evident in a scene from the movie The Meg – the screen became noticeably darker than in competing televisions. Despite this drawback, the results of the Bravia 8 II still place it among the very top of the market. It deserves praise for its absolutely top-notch color gamut coverage – DCI-P3 at nearly 100%, and BT.2020 close to 90%. These parameters allow for fully extracting the potential of HDR content and providing a cinematic experience in the comfort of your home.

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.

Right out of the box, the Bravia 8 II performs really well. In the best IMAX® Enhanced mode, the television can reproduce colors in a pleasing and natural way, although “good” here does not mean “best in class.” The white balance definitely needs adjustment – skin tones tend to lean into slightly pink/cool hues, both in SDR and HDR materials. We also noticed that the EOTF curve characteristics show a tendency to brighten the darkest parts of the image. This is probably due to the manufacturer's desire to highlight as many details as possible, even in deep shadows. Is this a good approach? It's hard to say definitively, but we know one thing – it's not an ideal solution.

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…

After calibration, the excessive cooling of the image caused by the strong boost of blue color was eliminated. Reds became deeper, and skin tones took on a natural, healthy appearance. Actors who previously seemed "cold" now appear much livelier and more convincing on screen. However, one thing has not changed – the analysis of the EOTF curve still shows that the Bravia 8 II tends to lighten the darkest parts of the image. It's hard to say whether this is a deliberate choice by the manufacturer or a result of the panel design and software. In practice, this means that scenes the creators wanted to leave in deep darkness can reveal more details than intended. Nevertheless, the viewing experience after calibration is clearly better – warm, natural colors and realistic skin tones make watching on the Bravia 8 II simply more pleasant to the eye.

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.

Upscaling and digital image processing are a true showcase of the capabilities of Bravia 8 II. Sony has long been regarded as a master in this field, and here it only confirms its reputation. The proprietary XR processor can extract nearly maximum quality from lower resolution materials—whether it's television or an old DVD movie, the image looks sharper, with more details and better depth. Sure, if we feed it exceptionally low-quality material (like our archival photo with the Model), it won't work miracles, but in everyday viewing, it's hard to find anything to complain about.

The soft gradation feature also performs excellently. In the "Medium" setting, it effectively smooths tonal transitions, eliminating banding on colored and gray gradients, while simultaneously preserving film grain and fine image details. It is this balance between delicacy and effectiveness that keeps Sony TVs among the best on the market in this category.

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.

Motion smoothness is practically a closed topic in the case of Bravia 8 II. The OLED with 120 Hz refresh rate naturally provides a very clean, clear image in dynamic scenes, so there is little to complain about. However, particular praise is due to one of the best motion smoothing systems on the market. They allow for precise adjustment of film smoothness according to one's preferences – from gentle smoothing to an almost "theatrical" effect – without the risk of artificial jumps, tearing of the image, or annoying artifacts. This is one of those features that will be appreciated both during movie screenings and while watching sports.

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.

Sony really learned its lesson from previous years and in the Bravia 8 II prepared a package of features for gamers that is difficult to describe as anything other than "almost perfect." We have everything expected in equipment of this class – VRR, ALLM, Dolby Vision Gaming mode, HGiG, and even a convenient Game Bar that allows you to quickly preview parameters and change settings without leaving the game. Additionally, it's worth noting how smoothly and flawlessly these features work – no delays, no strange stutters. You simply turn on the game and everything looks as it should. Unfortunately, there are a few "buts." The manufacturer still gives us only two full-bandwidth HDMI ports, so if someone has a console, a PC, and another device like a Soundbar connected via eARC, it starts a game of cable swapping. It's also surprising that there is no support for 1440p resolution at 120 Hz – particularly important for Xbox gamers. Overall, however – this is one of those TVs that can comfortably be placed in the center of a gaming lounge, allowing you to enjoy gameplay without significant compromises.

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.
