Sony Bravia 7 (XR70) vs TCL C655 Pro

Since we know that the television performs well with contrast, let's check how it fares in terms of HDR effects. The luminance graph shows the very high capabilities of this model – 1500 nits is truly an impressive result. HDR effects are particularly striking in scenes where most of the screen is covered in light, as seen in the 1st, 3rd, and 5th test scenes. Minor shortcomings, typical of this technology, are still noticeable with very small light effects, such as in the scene from the movie "Sicario 2," where brightness drops to 500 nits. Although these are not stunning results, they can be considered decent. Additionally, it is worth praising the television for its high coverage of a wide color gamut – DCI-P3 at 96%, which allows for vibrant, saturated colors.

In the HDR effect quality category, the TCL 655 PRO television shows decent capabilities, achieving 550 nits of peak brightness. This allows for enjoyment of HDR effects, which is clearly visible in scenes such as the first from the movie Life of Pi or the last frame from The Meg. However, the limited number of dimming zones causes some problems. While in bright scenes the television performs better than its lower model, in more demanding scenes, such as the second and fourth scenes from Sicario 2, it struggles. The dimming algorithm aims for deep blacks, but at the cost of brightness – which in these moments leads to a decrease in brightness by as much as half. In these more challenging scenes with small elements, it is hard to find any praise, and the HDR effect resembles rather SDR. Nonetheless, the coverage of the color palette deserves commendation, which, like in the version without the PRO suffix, is at a very good level.

The IMAX Enhanced mode on the Sony BRAVIA 7 television is definitely the best mode available on this model, although it is not without its flaws, as its name might suggest. The biggest issue is white balance – both in HD and 4K HDR content, there is a noticeable dominance of red color, which makes the image take on pinkish shades. This is particularly evident on the tested snow screen, where the pinkish hue becomes very noticeable. Errors in the Colour Checker test also confirm these deviations – although they are not catastrophic, there is a tendency to lean towards warmer tones. As for brightness characteristics, gamma remains at a decent level with a slight bump but without major issues. However, the biggest challenge is 4K materials. It is clear that the EOTF curve is significantly above the reference chart, which causes the image to become too bright.

Each of our TV tests is conducted in movie mode, which usually offers the best color reproduction. Nevertheless, even this mode is not free from problems, as we noted with the TCL 655 PRO model.

In the case of HD content, the white balance clearly shifts towards red, and this effect becomes particularly noticeable in a scene from Star Wars, where the white elements of the scenery take on a pink hue. For 4K HDR material, the situation looks better, but there is a tendency to excessively enhance the blue color. As a result, the image can appear artificially sharp, which proves to be uncomfortable for the eye over a longer period. The brightness characteristic also leaves much to be desired. The Gamma chart indicates serious difficulties with excessive brightening, causing the overall presentation to look washed out. Additionally, the EOTF curve reveals significant issues with the reproduction of very small elements - they are excessively dimmed, as we detailed in the paragraph regarding HDR effects.

Sony BRAVIA XR70 offers a wide range of tools that allow for customizing the picture to personal preferences, which has enabled us to make significant adjustments to the settings. The white balance has been free of the issue of red hue dominance – snow no longer ends up with pink shades, which was previously noticeable. Although one can detect minor deviations at the end of the white balance chart concerning a drop in blue color, they are acceptable and hard to notice in everyday use. The Colour Checker test confirms that color reproduction errors are no longer as pronounced and rarely exceed a value of 2, which is a very good result. As for brightness, gamma, while not requiring significant improvement, has been slightly adjusted. However, the most notable change has been observed in the EOTF curve – the television no longer has issues with overly brightening the entire image in 4K content. However, upon closer analysis and enabling EOTF characteristics in films, certain limitations of the television arise due to the previously discussed dimming algorithm. Some small elements may be slightly more illuminated, but these errors are so minor that most users will not notice them. Overall, the calibration results are very, very positive.

After calibrating the TCL 655 PRO television, a noticeable improvement in white balance can be observed, having completely eliminated the tendency for the screen to have an excessive pink hue, which was previously visible in factory mode. The image has taken on more natural tones, especially in white and bright elements, positively affecting the overall perception of the picture. As for brightness characteristics, the Gamma chart has also improved – the screen is no longer excessively bright, which previously made the image look washed out. Nevertheless, there are still some issues with the EOTF curve that are difficult to eliminate due to the design of the television and its limited number of dimming zones. These limitations prevent achieving ideal results in this regard. However, despite this minor flaw, the overall effect after calibration is truly outstanding, providing high image quality and very good color reproduction.

Since we know that the television performs very well with high-quality materials, it is worth checking how it fares with lower-quality content. Here the television shows its potential, and the applied graphics processor works really well. On the test board with the light bulb, there are no visible issues with color transitions, and the smooth gradation function works very well – we recommend setting it to "Medium".

When it comes to digital processing, or so-called upscaling, the television sharpens the image quite a bit, which leads to slight aliasing, for example on branches in the background, but it does not remove desired details. Nonetheless, the overall appearance is truly attractive and may appeal to most users. However, if we prefer a softer, more plastic image, this effect can be reduced in the settings by adjusting the sharpening level to our personal preferences.

The TCL 655 PRO television handles tonal transitions in lower-quality materials quite well. The "Gradual Smoothing" feature at a low setting effectively smooths out tonal transitions; however, this comes at the cost of losing some important details, such as the texture of objects. A positive aspect is that it does not negatively affect film grain, which helps maintain the natural look of the image.

In the context of digital processing, the television adds artificial sharpness. This may appeal to users who prefer a more vivid image. However, those who favor a softer, subtler look may find this to be a drawback. Additionally, a downside is the image cropping due to overscan, which limits the field of view and trims the edges of the frame. This can be problematic in certain scenes - e.g., news tickers.

The Sony BRAVIA 7 television with a 120 Hz panel will satisfy most users in terms of motion smoothness. Additionally, Sony offers the Motion Flow feature, which allows for the selection of three different picture settings, adjusting them to personal preferences: Smoothness – Film: This setting improves motion smoothness, giving the image a more cinematic or theatrical character. Smoothness – Camera: This setting provides even greater smoothness, useful when watching dynamic scenes such as sports broadcasts. Clarity: This setting focuses on minimizing noise and motion artifacts, resulting in a more stable and clear image.

The TCL C655 PRO TV is equipped with a 4K panel with a refresh rate of 60 Hz, making it ideal for watching movies. Additionally, the "Flicker Reduction" feature allows users to adjust the fluidity of the image, giving them the choice between smoother motion or a cinematic, choppy effect. Moreover, the TV handles lower resolution content well, such as Full HD and 2K, offering a refresh rate of 120 Hz, which will certainly appeal to gamers who can enjoy smoother images, albeit at the cost of lower resolution.

Sony Bravia 7 has significantly improved its capabilities for cooperation with consoles compared to previous models. The TV supports variable refresh rate (VRR), which eliminates screen tearing, and it is compatible with graphics cards, ensuring smooth display. The auto low latency mode (ALLM) effectively reduces input lag, which is crucial in fast-paced games. Dolby Vision with low latency additionally provides impressive HDR effects that look great during gameplay.

Sony Bravia 7 also offers a Game Bar feature that provides quick access to settings and allows monitoring of parameters during gameplay. An interesting option is the ability to enable a virtual crosshair on the screen, which can give a slight advantage in shooting games. However, compared to the Bravia 9 model, the HGIG feature in the Bravia 7 does not perform as well, which may be noticeable for more demanding gamers – especially since the HGIG mode is becoming more popular in the gaming world as the preferred method for reproducing HDR effects.

A downside is the lack of support for 1440p@120 Hz resolution, which could make gaming easier for users with less powerful graphics cards. Additionally, the Sony Bravia 7 is equipped with two HDMI 2.1 ports, one of which is often used to connect an audio system via eARC, limiting the number of available ports for connecting next-generation consoles.

The TCL C655 PRO television offers an almost perfect set of features for gamers, supporting all key technologies that significantly improve the gaming experience. The ALLM feature automatically switches the television to low latency mode, resulting in better responsiveness and minimized signal delays – particularly important in dynamic titles. VRR synchronizes the screen refresh rate with the number of frames generated by the console, eliminating screen tearing and thus guaranteeing smoother gameplay.

Support for Dolby Vision in game mode allows for more detailed color and contrast reproduction in games that support this format, while the Game Bar provides quick access to important settings such as response time or latency level. Unfortunately, this model does not support 4K resolution at 120 Hz, which may disappoint the most demanding gamers. However, for those who can forgo 4K, support for Full HD and 2K at 120 Hz offers exceptionally smooth visuals, making it an attractive alternative for enthusiasts of higher refresh rates.
