TCL C6KS / C69KS / Q6CS vs SONY BRAVIA 3 II (XR35M2)

And what about HDR? Here, the C6KS performs quite well and – as has become a recurring theme of this review – identically to the C6K model. The maximum brightness generated by this television is around 600 nits. In bright scenes, this translates to a really solid, cinematic effect, and generally, the video materials look good here. However, one must keep in mind the specifics of the dimming algorithm in this model. When very small, bright points (e.g., stars) appear against a dark background, the television can dim them quite significantly. The goal is simple: to eliminate blooming and maintain the best possible blacks. This is quite a reasonable compromise. Most viewers will definitely appreciate deep, "true black" more than additional micro-details, the display of which could cause the screen to appear greyed out. This is the nature of local dimming technology in this price range, and one must be aware of it. It is also worth noting that the TCL C69KS (C6KS) has an additional PFS coating, which is marketed under the slogan of QLED technology. Thanks to this, the colours are saturated and vibrant – our measurements showed that the coverage of a wide colour gamut reaches as much as 92% here.

Bravia 3 II is certainly not a TV that tries to impress with brightness. In our measurements it reached about 450 nits, so it falls well short of the brightest models on the market. That does not mean HDR is just a paper feature. Compared with ordinary SDR material, the brightest elements of the image can already come through noticeably, and reflections, highlights and stronger exposures have a bit more energy and stand out better from the rest of the scene. This is most obvious in simpler shots where the screen displays many bright elements. Then the Bravia 3 II can give a hint of a higher dynamic-range picture. The problem only begins with more demanding content, where much greater brightness headroom is required. There the TV quickly shows its limitations and instead of powerful, striking HDR we get only a competently rendered picture.

Colours

Bravia 3 II uses a QLED-type panel, although technically it does not use a classic quantum dot layer. Instead Sony has used a solution based on PFS phosphor, which performs a very similar role: it allows more saturated reds and greens and thus enables a much wider colour gamut. In measurements DCI-P3 coverage was around 94%, and the very wide BT.2020 around 74.4%. These are good results for this class of hardware, which mean the Bravia 3 II has no problem reproducing sufficiently saturated colours in HDR content. Colours do not look washed out, and more intense hues can look genuinely attractive.

Unlike the more expensive C6K model, the tested C6KS does not have an option in the menu labelled as Filmmaker Mode. Is this a reason to cry? Absolutely not. Our tests have shown that in practice, in terms of colour reproduction, the lack of this specific label makes virtually no difference. The best available Film/Cinema mode here offers an almost identical picture characteristic to the aforementioned Filmmaker in the more expensive model. So we get a very similar image, just under a different name. Therefore, if you were wondering whether paying extra for the C6K gives you better colours – the answer is no, in both cases the base is the same and requires slight adjustments.

In Professional mode the Bravia 3 II already delivers a fairly good level of colour reproduction straight out of the box. In SDR the most noticeable issue is a slightly low gamma, which makes the midtones a little brighter. White balance isn't perfect either; as brightness increases the blue and red components become slightly lacking, so whites can at times take on a marginally warmer, faintly greenish tint. These are not faults that immediately catch the eye when watching a film. Average error values hover around 3, so the factory setting can be regarded as quite good. The situation is similar in HDR. Here too there is a slight lack of the blue component, so the image is marginally warmer than the reference, but the difference is not large enough to significantly interfere with normal viewing.

Thanks to the white balance adjustment, the C69KS's tendency to distort colours has been effectively limited, resulting in a very good final effect. After calibration, we will no longer see excessive warming of scenes in SDR or overly cool tones in HDR. However, it is worth noting the brightness characteristics. In SDR content, it is hard to have any objections – the image looks very good, especially in older films, television programmes, or materials from YouTube. It is significantly more challenging to evaluate the television's performance in HDR. Analysis of the EOTF curve suggests correct behaviour, but its practical variant reveals certain limitations. The C69KS can overly brighten the smallest elements of the frame, while at other times, it can dim the entire scene. Thus, calibration brought clear benefits in terms of colour quality, but certain limitations resulting from the local dimming operation and the way it is controlled by the C69KS cannot be overlooked, as we also saw in the C6K test.

After calibration, there is particularly a lot to be gained from SDR content. The white balance was set almost perfectly, the gamma practically matches the reference value, and the average colour errors fell from around 3 to about 1. That is already a level at which differences from the reference image are, in practice, very difficult to detect. The Bravia 3 II therefore shows that, despite its position in Sony’s lineup, it has quite a lot of potential for precise picture calibration. Improvements are also visible in HDR, although here it is no longer possible to avoid all the limitations of the TV itself. After evening out the colours, it is easier to notice that the EOTF curve in film content runs slightly below the reference value in places, so the Bravia 3 II gently darkens part of the image. This is not an ideal solution from a reference point of view, but in this particular TV it also has its benefits. With no local dimming and average black levels, this behaviour slightly reduces the visibility of the backlight in darker scenes and helps maintain a stronger impression of contrast. So you could say Sony partly masks the limitations of the panel this way, instead of trying at all costs to stick to the reference luminance.

The C69KS handles upscaling quite well. The tested 576p material looks surprisingly decent – a considerable amount of detail is retained, and the algorithm adds a slight "rounding" effect to sharp edges, making the image appear more cohesive. The performance in smoothing tonal transitions is less impressive. The television practically cannot improve them, leaving the image in a rather raw state. With older material, this can be quite tiring, as the lack of additional processing highlights any imperfections.

The Bravia 3 II is Sony's first TV to use the new MediaTek Pentonic 800 chipset, and there are a few changes in image processing. Starting with the basics. The upscaling itself is adequate. The TV can sensibly pull up lower-resolution material and does not have a strong tendency to over-emphasise jagged edges or other source imperfections. With regular broadcast TV or weaker streaming material the picture therefore remains quite pleasing. We have more reservations about the digital image processing. In this model Sony has replaced the well-known "Smooth Gradation" function with a new setting called "Digital Noise Reduction". Its role is essentially very similar: it is supposed to smooth unpleasant tonal transitions and artefacts resulting from heavy signal compression. Unfortunately, this function performs noticeably worse than before. At the "High" setting (the only one that had any visible effect) the TV can smooth away too many elements of the image at once, causing film grain to disappear and the texture of objects or even skin to start looking unnatural. Worse still, the effect is not particularly stable. When a scene contains more motion, the function's effect clearly weakens and at times it looks as if the TV stops intervening in the picture altogether. For everyday viewing we therefore would not recommend using it at a high level. It can help on a static shot, but the price is often an excessive loss of detail.

C69KS offers a simplified motion enhancement panel in films, allowing the adjustment of effect intensity with a slider. This makes it easy to match fluidity to personal preferences. The ability to use higher refresh rates is also a plus – although the panel operates natively at 4K at 60 Hz, lowering the resolution to 1440p enables 120 and 144 Hz modes, both on consoles and PC. This sounds like great news, however, in practice, the image at these settings exhibits significant motion blur. The effect is so pronounced that the overall presentation appears merely average and loses its appeal for everyday use.

Motion handling is definitely one of the Bravia 3 II's strongest points. The TV uses a 120Hz VA panel, a solution that, by nature, despite the high refresh rate, does not always cope well with motion blur. Here, however, Sony has managed to keep that problem very well under control. Fast-moving objects remain crisp, and the characteristic trails and blurring are reduced to a very low level, if not to zero. It is one of the least motion-blur-prone LCD TVs we have tested. Interestingly, in this respect the Bravia 3 II can even outperform the much more expensive True RGB flagship series, the Bravia 9 II.

If we overlook the smudging and lack of native 4K at 120 Hz, the C69KS impresses with how well it performs during gaming. We get everything one can expect from a gaming television: variable refresh rate (VRR), automatic switching to game mode (ALLM), Dolby Vision Gaming mode, and a well-functioning HGiG. The television can also operate at 120 and even 144 Hz at lower resolutions, allowing for smoother gameplay on a console or PC. Additionally, there is a clear Game Bar that lets you quickly glance at key settings while gaming. As a result — despite a few limitations — the C69KS can be a really successful screen for gamers.

Sony Bravia 3 II is a very good TV for gamers, although not everything has been implemented exactly as we would like. The biggest change concerns the connectors. For the first time in a Sony TV we get as many as four full HDMI 2.1 ports with 48 Gb/s bandwidth, thanks to the new MediaTek Pentonic 800 chipset. That removes one of the issues that has plagued this manufacturer’s TVs for years. We can connect several devices at once and on each input use the device’s full capabilities, for example VRR or ALLM. There is also a simple Game Bar that lets you view key signal parameters and change a few useful settings, such as black level, when you want to improve visibility in darker parts of a game. However, there are two limitations worth knowing. The first is the lack of support for 1440p at 120 Hz. That will not be a problem for everyone, but people using that resolution on a console or PC, for example to get higher frame rates in certain games, will have to choose 1080p. We have more reservations about HGiG support. Sony does not allow you to disable the TV’s tone mapping on the Bravia 3 II, so the screen is always processing HDR content even when you would prefer to leave that task to the console. This is most obvious during HDR setup — the checkerboard pattern does not disappear at the point that corresponds to the TV’s actual capabilities. That does not mean HDR in games will look bad. You just need to approach the setup a little differently and, instead of relying on the pattern, manually set the peak brightness to around 450 nits. The issue can be worked around, but you should know about it before you start setting up the console.
