TCL C655 / C69B (55"-85") vs Sony BRAVIA 7 II

Generally speaking, the quality of the HDR effect on the TCL C655 / C69B looks quite promising. The average value in the test charts is around 450 nits, which already allows one to feel the light effects and better image dynamics. However, as previously mentioned, this effect may be partially subdued by slight differences in bright and dark colours, resulting from the lack of local dimming technology. However, the coverage of the DCI-P3 colour palette at 94% deserves high praise, and this is made possible by the use of a quantum dot (QLED) matrix. As a result, colours are vivid and accurately represented when watching HDR content.

The Sony Bravia 7 II handles HDR very well and, above all, is simply a bright television. In the correct viewing mode, Professional, we measured around 2,000 nits of peak brightness, so the panel’s capabilities are truly significant. Of course, with Mini-LEDs a test pattern result is only part of the story, because a lot still depends on how the TV controls the backlight in real scenes. Here Sony’s algorithms perform very well. Depending on the scene, the brightness we measured in films ranged from roughly 1,100 to as much as 1,700 nits. That’s already a level at which HDR has proper punch and bright highlights can be genuinely impressive. It isn’t perfect in every situation, though. With small bright elements on a very dark background the Bravia 7 II clearly favours maintaining good blacks, which can cause their brightness to drop to around 500 nits. It still looks good, but you can see the TV does not always manage this without compromise.

Colours

The second thing that has a huge impact on HDR is, of course, colour. And this is precisely where True RGB technology was meant to bring one of the biggest changes. Looking at the panel’s capabilities alone, the Bravia 7 II performs very well. We measured about 98% DCI-P3 coverage and 88% BT.2020, so the potential to show strongly saturated colours is really large. In RGB TVs, however, the situation is a bit more complex. When we repeated the same measurements with a film background applied, palette coverage fell to around 92% DCI-P3 and 78% BT.2020. Those are still good figures, especially for an RGB Mini-LED TV, but they clearly show that the final result largely depends on how the algorithms control the three backlight colours. In most scenes the Bravia 7 II handles this well and colours retain high saturation. The biggest differences are visible in shades of blue, where samples begin to deviate more noticeably from reference values and coverage is weaker than for the other primary colours. True RGB therefore offers genuinely greater potential here, but, as with brightness, much depends on what is happening on screen.

The television TCL C655 / C69B offers a film mode that has been tested for colour reproduction quality. Although this mode is called film mode, it unfortunately has several errors that a director would surely not want to see when recording their work. Starting with image analysis, it is worth examining the white balance – both in HD and 4K HDR content, the white balance has significant errors. In both cases, the red colour dominates, causing the colours to be too warm, and the overall result takes on a pink or yellow tint. This can be seen in the image below from the film "Star Wars". The Colour Checker test confirms these errors – the colour samples veer into incorrect shades, affecting the overall colour fidelity. A less significant issue is the brightness characteristic. However, this is also not without its flaws. The gamma graph shows a strong peak at the beginning, causing the image to be excessively brightened, and the EOTF curve responsible for brightness in 4K HDR material also has substantial fluctuations – it is noticeable how the television tries to maintain the appropriate brightness, but it does not always succeed effectively.

To evaluate the factory colours we chose the Professional mode, because it performs best among the available settings. However, it is not perfect. In SDR the white balance drifts slightly towards magenta, making some scenes look a little warmer and less neutral than they should. A bigger problem is the gamma, which sits closer to 2.5 than to 2.4. This makes the image a bit too dark in places, particularly in the midtones. In HDR the situation is better. As brightness increases a little too much red appears, but this is not an issue that is highly noticeable during viewing. Overall the Professional mode is a good starting point, although you can get a bit more out of it after calibration.

After calibrating the television's film mode TCL C655 / C69B , the white balance has been adjusted, and the colours are presented as they should be – confirmed only by slight deviations in the Colour Checker test. The gamma is really quite accurate, which means the television should not have issues with brightness in low-resolution materials. Unfortunately, a similar EOTF characteristic is still visible, which is a natural phenomenon in televisions that do not have local dimming – they simply struggle to "shine" more in a given area of the screen. Despite this inherent limitation that cannot be bypassed, we recommend adjustment in the settings, as the overall colour presentation looks really very good.

After calibration the Bravia 7 II can look decidedly better. Above all, we managed to set the white balance very well, both in SDR and HDR. Gamma can also be improved, which after correction runs very close to the reference value. And in fact, for most users these changes will have the greatest impact on the picture. There is, however, a limitation when it comes to the colours themselves. In the Bravia 7 II Sony does not provide access to a classic CMS that would allow us to correct individual hues separately. A lot is therefore left in the hands of the algorithms controlling the True RGB backlight. If the TV misrepresents a particular colour, we are not always able to do anything about it. In our measurements this is most visible in certain reds and blues, where errors can still be quite large. This does not, however, undermine the point of calibration itself. Correctly setting the white point and gamma strongly affects the whole picture, so even without the ability to precisely correct every colour the difference compared with the factory settings is noticeable.

The television TCL C655 / C69B handles tonal transitions fairly well in low-quality materials. The "Gradual Smoothing" feature at a low setting effectively smooths out tonal transitions; however, it simultaneously blurs significant details, such as the texture of objects. On the plus side, it does not negatively impact the film grain, allowing the natural appearance of the image to be preserved. As for digital processing, the television adds artificial sharpness, which may appeal to some users who prefer a sharpened image. However, for those who prefer a softer look, this could be a disadvantage. A notable downside is that the image has been quite significantly cropped due to what is known as overscan, which reduces the field of view and trims the edges of the image.

Scaling and digital processing are among the strongest points of the Bravia 7 II and one of the bigger reasons to choose Sony over the competition. The manufacturer has been handling digital image processing well for years, and it shows here too. First and foremost, the 'Smooth Gradation' function works very well and can smooth out weak tonal transitions in lower-quality material. The safest setting is Low, but we would comfortably recommend Medium as well. The effect is stronger then, yet the TV still treats details very gently. Some fine details may be slightly smoothed, but Sony does this much more subtly than many other brands. The upscaling itself also performs very well. Lower-resolution material is well upscaled to 4K, the image looks clean and retains a lot of detail. Of course the TV will not magically turn native HD material into true 4K, but what can be extracted from such a source is handled really well by the Bravia 7 II.

The television C655 / C69B is equipped with a 4K@60 Hz panel, which means it works best for watching films and less dynamic content. It also features a "Flicker Reduction" function that allows for the adjustment of image smoothness – the user can choose whether they prefer smoother motion or a more cinematic, frame-by-frame effect. The television can also adapt to lower resolutions, such as Full HD and 2K at 120 Hz, which will surely please gamers by offering a smoother image at the cost of resolution. It is worth noting that this feature is available in sizes from 55"+. Additionally, the largest variant, 98", is equipped with a 144Hz panel with full motion smoothing.

The Bravia 7 II uses a 120 Hz panel, so in terms of motion handling it delivers everything you would expect from a TV of this class. With sport or games at 120 fps, the picture is suitably smooth, and for films Sony provides an extensive motion interpolation system. You can therefore adjust the interpolation level separately and decide whether you want to preserve a more cinematic character to the motion or obtain noticeably smoother movement. The issue of motion blur itself is a little worse. The VA panel used is not among the fastest, and you can notice a slight trail behind moving objects, particularly on darker backgrounds. It is not at a level that greatly bothers during normal viewing, but last year’s Bravia 7 fared better in this respect and had a noticeably faster panel.

The TCL C655 / C69B television offers nearly the perfect set of features for gamers, supporting all the most important technologies. It has an ALLM feature that automatically switches the TV to low latency mode, significantly improving responsiveness and minimising signal lag, which is especially important during dynamic gameplay. The VRR feature allows the screen refresh rate to synchronise with the frame rate generated by the console, eliminating screen tearing and providing smoother gameplay.

The television also supports Dolby Vision in game mode, which ensures better colour and contrast rendering in games that support this format, and the Game Bar provides quick access to settings related to gameplay, such as response time, latency level, and other parameters. Unfortunately, the C655 / C69B does not support 4K resolution at 120 Hz (the exception here is the 98" variant), which may be disappointing for more demanding gamers who expect the highest fluidity of image in high-resolution games. However, if we can forgo 4K, the television offers support for Full HD and 2K at 120 Hz, providing a smoother image and is a great alternative for those who prefer a higher refresh rate at the expense of resolution.

Bravia 7 II has basically everything you’d expect today from a good console TV. It supports 4K at 120 Hz, VRR from 48 to 120 Hz and ALLM, so when you start a game the TV automatically switches to a low-latency mode. It also has properly working HGiG, which means that after configuring HDR on the console the TV won’t try to brighten the image further on its own. You just need to remember to turn off tone mapping in the TV’s menu. Dolby Vision in game mode is also a plus, especially useful for Xbox owners. Sony adds its own Game Menu. From it you can quickly check key signal information, verify VRR operation or change gaming-related settings without digging through the whole TV menu. The only thing missing from the feature list is support for 1440p at 120 Hz.

Our biggest reservation is not really about the functions themselves, but about the connectors. The Bravia 7 II has four HDMI ports, but only two of them support full HDMI 2.1 at 48 Gbps. One of those is also an eARC port. So if you connect a soundbar or AV receiver to the TV via HDMI, in practice you’re left with only one full HDMI 2.1 for a console or PC. With a single console that’s no problem, but with a PS5, an Xbox and an audio setup it starts to get tight. And this is hard to excuse for Sony. In cheaper TVs two HDMI 2.1 ports can still be acceptable, but in a model of this class, especially in 2026, we would expect a full set of four such ports.
