Sony Bravia 8 (XR80) vs TCL C75B

The Sony Bravia 8 performs commendably in terms of HDR brightness, reaching a peak of 880 nits. This level is sufficient to render lighting effects effectively in most scenes. In tested clips from Life of Pi and Sicario 2, the television demonstrated vibrant, detailed imagery that captured the atmosphere of these films beautifully.

However, challenges arise in scenes with consistently high brightness, such as in The Meg, where the display's limitations become apparent. In these situations, OLED technology can struggle, with brightness levels dropping to around 450 nits, which can be less satisfying when intense illumination is needed throughout a scene. Despite this, the Sony Bravia 8 remains a strong contender, offering excellent DCI-P3 colour gamut coverage and 74% BT.2020 coverage. These attributes result in rich, accurate colours and fine details, enhancing HDR content and providing an enjoyable viewing experience.

During our luminance test, the TCL C75B "spat out" about 380 nits of brightness. We recorded similar results while watching most of the films we tested. These can be considered average – the television does not perform badly in this segment, but around 400 nits is definitely too low to fully experience the magic of HDR effects. Of course, such results are better than those of budget models, which can achieve nearly half as low brightness values. However, for HDR enthusiasts seeking stronger light effects and greater realism, the C75B may prove insufficient. On the plus side, it's worth mentioning the 95% coverage of the DCI-P3 color palette. This is a very good result that easily suffices to enjoy a wide range of colors in content available on popular streaming platforms. Vivid and rich colors are definitely a strong point of this model.

The best factory mode on the Sony Bravia 8 television is IMAX Enhanced, offering the most cinematic experience, though it isn't perfectly calibrated. The TV attempts to replicate cinematic settings as accurately as possible, but some issues are evident. Starting with white balance, both for SDR and 4K content, there is a noticeable blue dominance, making the image appear too cold and lacking in natural warmth. Colour Checker tests reveal a shift towards cooler tones, affecting colour accuracy and making the image feel less lifelike.

Regarding brightness and contrast, the gamma shows a significant drop towards the end of the spectrum, meaning dark details may become too shadowed, and bright areas too intense, causing a loss of subtlety and detail. This is particularly noticeable in the sky, as seen in the comparison image. Additionally, the EOTF curve is considerably above the reference value, making bright elements overly intense. As a result, users may experience an unnatural image, with bright parts losing detail and negatively impacting the overall viewing quality.

TCL C75B offers many picture modes, but in our opinion, the best choice is the "Film" mode. Although its settings are quite good, the television struggles with certain color reproduction issues. In tests, we noticed that the image had a noticeably pinkish tint compared to what could be considered correct. This effect was particularly noticeable in skin tones, which appeared unnaturally warm. The main culprit of this phenomenon turned out to be the white balance, characterized by an excessive amount of blue and red in both HD and 4K HDR materials.

Another issue was the way brightness was reproduced. The gamma, which is responsible for the visibility of details in darker materials, was definitely boosted, causing details in the darkest parts of the screen to be invisible, lost in total blackness (e.g., the bottom part of the screen in the comparative photo - the area around the actress's ear). Similarly, the situation was reflected in the EOTF curve, which was below the correct value, suggesting that a similar problem may be encountered in 4K HDR content.

Thanks to our experience and the appropriate tools, we decided to take matters into our own hands and see how much could be extracted from this model after professional calibration. Details are described in the next section.

The calibration process of the Sony Bravia 8 television resulted in significant improvements in image quality. The white balance was notably enhanced for both SDR and 4K HDR content, with minimal errors in the middle section of the graph. Gamma calibration was one of the biggest improvements, eliminating previous dips that had impacted brightness stability and the reproduction of detail in dark areas. The EOTF curve was also corrected, making bright elements appear more natural and improving the overall tonal balance.

However, the most attention should be given to colour reproduction, where some issues persist despite calibration. Sony has omitted the CMS system in this model, which would allow for more precise colour control. As a result, the Colour Checker test for 4K content still reveals significant colour inaccuracies. Despite these limitations, calibration is still recommended, as the improvements in brightness and contrast are noticeable and greatly enhance the overall image quality.

After calibrating the TCL C75B, it has clearly improved in terms of color reproduction. Although the TV does not offer many options for adjusting the white balance, we were able to refine its settings significantly. As a result, the image has stopped being overly pink, and the colors now look much more natural and harmonious.

The gamma jump, which was previously a problem, has not disappeared completely, but we managed to significantly reduce it. This has made the details in dark scenes more visible – both in HD and 4K HDR material.

Unfortunately, the lack of local dimming is still noticeable. The "glowing black" effect remains, but that's a limitation of the display itself. Despite this, the colors after calibration look vastly better, and the image is much more enjoyable to watch.

The fluidity of tonal transitions in lower-quality materials on the Bravia 8 is lacking. Unfortunately, the gentle gradation function, which was available in previous models, is missing, which is a significant drawback. The digital noise reduction feature can improve tonal transitions, but it often removes fine details, such as clouds in scenes from The Martian, which may not be to everyone's taste. On the other hand, the digital processing in the Sony XR80 is quite effective. In test scenes, it performed well without noticeable flaws, and the branches in the background remained smooth without jagged edges. This indicates that the Bravia 8 is capable of handling complex low-resolution image details with relative ease.

The TCL C75B has a tonal transition smoothing feature, but unfortunately, we can't praise it. Regardless of the selected level – low or high – tonal transitions in older materials remained visible, as if the feature didn't work at all. It's hard to say something positive about it because, in practice, it seems completely useless.

The image scaling is better. The TV performs quite decently, although on thinner elements, like branches in the background, you can notice slight halos. However, this is not something that significantly interferes with daily viewing.

Unfortunately, a bigger problem turned out to be overscan, which is the trimming of the image edges. In our tests, it happened that news tickers or other elements close to the edge of the screen were cut off. This is definitely something worth paying attention to, especially if we use the TV for watching news programs or content with text on the screen.

The Sony Bravia 8 offers a maximum refresh rate of 120 Hz, ensuring smooth viewing of dynamic content such as sports and games, with sharp and fluid motion. For more demanding users, the Sony XR80 features an advanced motion smoothing system, divided into three settings: Smoothness (Film), Smoothness (Camera), and Clarity. The first two settings adjust the level of blur and smoothness, while the Clarity setting will be discussed in more detail below. Each of these parameters can be customised to suit individual preferences, allowing users to fine-tune the settings for the optimal viewing experience.

TCL C75B definitely has something to offer gamers. The TV is equipped with a panel that can display images with a refresh rate of 144 Hz in 4K, and even 240 Hz in Full HD. These are really great results, especially for a model from the budget range.

Additionally, there are features for improving smoothness and reducing motion blur in films. The "Motion" option allows for precise adjustment of the effect on a 10-step scale, providing a lot of customization options – everyone can set the smoothness to their liking.

The Sony Bravia 8 has greatly improved its compatibility with consoles compared to earlier models. It supports variable refresh rate (VRR), which eliminates screen tearing and can sync with graphics cards for smooth visuals. The Auto Low Latency Mode (ALLM) reduces input lag, a crucial feature for fast-paced games. Additionally, Dolby Vision with low latency enhances HDR effects, offering stunning visuals during gameplay.

The Sony XR80 also includes a Game Bar, which provides quick access to settings and monitoring tools during gaming. A notable feature is the option to enable a virtual crosshair on the screen, giving players a potential advantage in shooter games.

However, there are some drawbacks. The TV lacks support for 1440p@120Hz resolution, which would benefit users with less powerful graphics cards. Furthermore, the Sony XR80 has only two HDMI 2.1 ports, one of which is typically used for connecting an audio system via eARC, limiting the number of available ports for next-gen consoles.

The TCL C75B is undoubtedly a television designed for gamers. It offers almost everything that the most demanding console users need. With the implementation of full-bandwidth HDMI 2.1, the television supports features such as ALLM (automatic low latency mode) and VRR (variable refresh rate) – operating across the full capabilities of the TV, up to 240 Hz in Full HD resolution.

Additionally, the television supports advanced HDR technologies, including Dolby Vision and HGiG, which allows for even better detail representation in HDR-optimized games. The C75B is also equipped with a very convenient interface for gamers in the form of a Game Bar, where you can check all key parameters, such as refresh rate, input lag, or picture settings – all within one click's reach.

In a nutshell: the C75B is an excellent choice for gamers, offering a wide range of features that allow for fully enjoying the capabilities of modern consoles and games.
