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 to near-reference quality in films and series recorded in HDR format. In test materials such as Life of Pi and Sicario 2, the effect is absolutely stunning – details in bright parts of the image remain perfectly visible, and night scenes captivate with depth and contrast. However, it’s not perfect. Compared to its most formidable competitors, the Bravia 8 II shows a noticeable drop in brightness during full-screen, very bright scenes. When comparing peak luminance with 100% white brightness in HDR mode, the Bravia 8 II can appear two or three times dimmer than LG G5 or Samsung S95F models. This was particularly evident in a scene from the film The Meg – the screen became noticeably darker than in competitors' televisions. Despite this flaw, the Bravia 8 II's results still place it at the forefront of the market. It deserves praise for its absolutely top-notch colour gamut coverage – nearly 100% DCI-P3 and close to 90% BT.2020. These parameters allow full potential extraction from HDR content and provide a cinematic experience in the comfort of your home.

And what about HDR? Here the C6KS performs quite well and – as is becoming the theme of this review – just like in 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, video materials look good here. However, it's important to keep in mind the specifics of the dimming algorithm in this model. When very small, bright points (e.g. stars) appear on a dark background, the television can quite significantly dim them. The goal is simple: to eliminate blooming and maintain the best possible black. It's a reasonable compromise. Most viewers will definitely appreciate deep, “true black” more than additional microscopic details, the display of which could cause the screen to appear greyed out. Such is the nature of local dimming technology in this price range, and one must be aware of this. It’s also worth noting that the TCL C69KS (C6KS) has an additional PFS coating, which is marketed under the QLED technology slogan. 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%.

Right out of the box, the Bravia 8 II performs really well. In the best IMAX® Enhanced mode, the TV manages to render colours in a pleasant and natural way, although "well" doesn’t mean "best in class" here. The white balance definitely requires adjustment – skin tones tend to lean towards slightly pink/cool tones, both in SDR and HDR content. We also noticed that the EOTF curve characteristics show a tendency to brighten the darkest parts of the image. This is likely 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's not an ideal solution.

In contrast to the more expensive C6K model, in the tested C6KS we don't find an option in the menu labelled as Filmmaker Mode. Is this a reason to cry? Absolutely not. Our tests showed 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 profile 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 would give 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 in blue colour was primarily eliminated. The reds became deeper, and the skin tones took on a natural, healthy appearance. The actors, who previously seemed "cold," now look much livelier and more convincing on screen. However, one thing hasn't changed – the analysis of the EOTF curve still shows that the Bravia 8 II has a tendency to brighten the darkest parts of the image. It's hard to say whether this is a deliberate effect by the manufacturer or a consequence of the panel's design and software. In practice, this means that scenes that the creators wanted to leave in deep darkness can reveal more details than intended. Despite this, the reception of the image after calibration is clearly better – the warm, natural tones and realistic skin shades 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, leading to a very good final effect. After calibration, we will no longer see excessive warmth in SDR scenes or overly cool tones in HDR. However, it is worth noting the brightness characteristic. In SDR content, there are hardly any objections – the image looks very good, especially in older films, TV shows, or YouTube materials. Evaluating the television's performance in HDR is much more difficult. Analysis of the EOTF curve suggests correct behaviour, but its practical variant shows certain limitations. The C69KS can overly brighten the smallest elements of the frame, while at other times it can dim the entire scene. Calibration has therefore brought clear benefits in terms of colour, but certain limitations resulting from local dimming and the way it is controlled by the C69KS cannot be avoided, which we also observed 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 confirms its reputation. The proprietary XR processor can extract nearly the maximum from lower resolution materials – whether it's TV or an old movie from a DVD, the image appears clearer, with more detail and better depth. Sure, if we feed it exceptionally poor-quality material (like our archival photo with the Model), it won't work miracles, but in everyday viewing, it’s hard to find fault.

The gentle gradation feature also performs excellently. In the “Medium” setting, it effectively smooths tonal transitions, eliminating stripes on colourful and grey gradients, while not destroying film grain or fine image details. It’s this balance between delicacy and effectiveness that keeps Sony TVs among the best on the market in this category.

The C69KS handles upscaling quite well. The tested 576p content looks surprisingly decent – a considerable amount of detail is preserved, and the algorithm adds a subtle ‘rounding’ effect to sharp edges, making the image appear more cohesive. However, it doesn't perform as well when it comes to smoothing tonal transitions. The television practically cannot improve them, leaving the image in a rather raw state. With older materials, this can be simply exhausting, as the lack of additional processing highlights all imperfections.

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

C69KS offers a simplified motion enhancement panel in movies, allowing users to adjust the intensity of the effect using a slider. This makes it easy to tailor the smoothness to personal preferences. It also deserves credit for the ability to utilise higher refresh rates – even though the panel operates natively in 4K at 60 Hz, by lowering the resolution to 1440p, modes of 120 and 144 Hz can be enabled, on both consoles and PC. This sounds like great news, however, in practice, the image at these settings trails exceptionally badly. The effect is so pronounced that the overall experience simply appears mediocre and loses its appeal in everyday use.

Sony has really done its homework from previous years and in the Bravia 8 II, it has prepared a package of features for gamers that is hard to describe as anything other 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 check parameters and change settings without leaving the game. It's also worth noting how smoothly and seamlessly these features work – no delays, no strange stutter. You simply turn on the game and everything looks as it should. Unfortunately, there are a few "buts". The manufacturer still provides us with only two full bandwidth HDMI ports, so if someone has a console, a PC, and another device like a Soundbar connected via eARC, the fun begins with plugging and unplugging cables. It's also surprising that there's no support for 1440p at 120 Hz – particularly important for Xbox gamers. Overall though – this is one of those TVs that can comfortably be placed in the centre of a gaming lounge and enjoyed without major compromises.

If we overlook the smudging and lack of native 4K at 120 Hz, the C69KS is impressive in how well it performs for gaming. You get everything you would expect from a gaming TV: Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), Dolby Vision Gaming mode, and a consistently functioning HGiG. The TV can also operate at 120 or even 144 Hz at lower resolutions, making gameplay on console or PC smoother. Additionally, there's a clear Game Bar that allows you to quickly check key settings while gaming. As a result — despite a few limitations — the C69KS can be a genuinely successful screen for gamers.
