Sony Bravia 8 MK2 vs TCL C6KS / C69KS / Q6CS

Thanks to the new QD-OLED panel, the Sony Bravia 8 II can achieve astronomically high brightness levels of around 2000 nits, translating into nearly reference-quality for films and series recorded in HDR format. In test materials such as Life of Pi and Sicario 2, the effect is truly captivating – details in bright areas of the image remain perfectly visible, and night scenes enchant with depth and contrast. However, it is not perfect. Compared to its fiercest competitors, the Bravia 8 II shows a noticeable drop in brightness during full-screen, very bright scenes. When comparing maximum peak luminance with 100% white brightness in HDR mode, the Bravia 8 II appears even two or three times dimmer than LG G5 or Samsung S95F models. This was especially evident in a scene from the film The Meg – the screen became noticeably darker than in competing televisions. Despite this shortcoming, the results of the Bravia 8 II still place it among the top of the market. It deserves praise for its absolutely top-tier colour gamut coverage – nearly 100% DCI-P3 and close to 90% BT.2020. These parameters allow for fully extracting the potential of HDR content and providing experiences akin to those in a cinema within the comfort of home.

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.

Straight out of the box, the Bravia 8 II performs quite well. In the best IMAX® Enhanced mode, the television is able to render colours in a pleasant and natural way, although “good” doesn’t mean “best in class” here. The white balance definitely needs adjustment – skin tones tend to lean towards slightly pink/cool hues, both in SDR and HDR materials. We also noticed that the characteristic of the EOTF curve reveals a certain tendency to brighten the darkest parts of the image. This is probably due to the manufacturer’s desire to highlight as many details as possible even in deep shadows. Is this a good approach? It’s hard to say definitively, but we know one thing – it is not an ideal solution.

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.

After calibration, the excessive cooling of the image caused by an overly strong boost of the blue colour was mainly eliminated. The reds have become deeper, and skin tones have taken on a natural, healthy appearance. The actors, who previously seemed "cold," now look much livelier and more convincing on screen. However, one thing has not changed – the analysis of the EOTF curve still shows that the Bravia 8 II has a tendency to brighten the darkest areas of the image. It is difficult to determine whether this is a deliberate method used by the manufacturer or a result of the panel and software design. In practice, this means that scenes which the creators intended to leave in deep darkness can reveal more details than anticipated. Despite this, the image quality after calibration is clearly improved – warm, natural colours and realistic skin tones make viewing on the Bravia 8 II simply more pleasant to the eye.

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.

Upscaling and digital image processing are a true showcase of the capabilities of the Bravia 8 II. Sony has long been regarded as a master in this field, and here it only reaffirms its reputation. The proprietary XR processor can extract nearly the maximum from lower-resolution materials – whether it's television or an old DVD film, the image appears clearer, with more detail and better depth. Of course, if we feed it exceptionally low-quality material (like our archival photo with the Model), it won't work wonders, but in everyday viewing, it's hard to find fault with it.

The gentle gradation feature also performs excellently. In the "Medium" setting, it effectively smooths tonal transitions, eliminating banding in coloured and grey gradients, while not destroying the film grain or fine details in the image. It is this balance between subtlety and effectiveness that keeps Sony televisions among the best on the market in this category.

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 smoothness of motion is practically a closed topic in the case of the Bravia 8 II. The OLED with a refresh rate of 120 Hz naturally provides a very clear, sharp image in dynamic scenes, so it's hard to complain about anything here. However, one of the best motion smoothing systems on the market truly deserves special praise. They allow precise adjustment of film smoothness to one’s own preferences – from gentle smoothing to almost a “theatrical” effect – without the risk of artificial jumps, tearing of the image, or annoying artifacts. This is one of those features that will be appreciated both during movie screenings and while watching sports.

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.

Sony has really learnt its lessons from previous years and in the Bravia 8 II has prepared a package of features for gamers that is hard to describe in any other way than "almost perfect". We have everything you'd expect from equipment of this class – VRR, ALLM, Dolby Vision Gaming mode, HGiG, and even a handy Game Bar that allows you to quickly preview parameters and change settings without leaving the game. It's also worth noting how smoothly and seamlessly these features work – no delays, no strange stutters. You simply start the game, and everything looks as it should. Unfortunately, there are a few "buts". The manufacturer still only provides us with two full-bandwidth HDMI ports, so if someone has a console, PC, and another device such as a soundbar connected via eARC, it becomes a hassle of switching cables. It is also surprising that there is no support for 1440p resolution at 120 Hz – particularly important for Xbox gamers. Overall, however – this is one of those televisions that can easily be placed in the centre of a gaming lounge and enjoyed without significant compromises.

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.
