Sony Bravia 8 (XR80) vs TCL C8K

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.

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.

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.

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 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.

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.
