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

And how does the issue of HDR look? Here the C6KS performs quite well and – as is becoming a recurring theme in 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 remember 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 black levels. It’s a reasonable compromise. Most viewers will definitely appreciate deep, “true black” more than additional micro-details that could cause grayness on the screen. Such is the nature of local dimming technology in this price range, and one must be aware of it. It’s also worth noting that the TCL C69KS (C6KS) has an additional PFS coating, which is marketed under the tagline of QLED technology. Thanks to this, the colors are saturated and vibrant – our measurements showed that the coverage of a wide color gamut reaches 92% here.

Right out of the box, the Bravia 8 II performs really well. In the best IMAX® Enhanced mode, the television can reproduce colors in a pleasing and natural way, although “good” here does not mean “best in class.” The white balance definitely needs adjustment – skin tones tend to lean into slightly pink/cool hues, both in SDR and HDR materials. We also noticed that the EOTF curve characteristics show a 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's not an ideal solution.

Unlike the more expensive C6K model, the tested C6KS does not have an option labeled Filmmaker Mode in the menu. Is this a reason to cry? Absolutely not. Our tests have shown that in practice, in terms of color reproduction, the absence of this specific label makes virtually no difference. The best available Film/Cinema mode here offers nearly identical picture characteristics to the aforementioned Filmmaker mode in the more expensive model. So we get a very similar image, just under a different name. So if you were wondering whether paying extra for the C6K gives you better colors – 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 the strong boost of blue color was eliminated. Reds became deeper, and skin tones took on a natural, healthy appearance. Actors who previously seemed "cold" now appear 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 tends to lighten the darkest parts of the image. It's hard to say whether this is a deliberate choice by the manufacturer or a result of the panel design and software. In practice, this means that scenes the creators wanted to leave in deep darkness can reveal more details than intended. Nevertheless, the viewing experience after calibration is clearly better – warm, natural colors and realistic skin tones make watching on the Bravia 8 II simply more pleasant to the eye.

Thanks to the white balance adjustment, the tendency of the C69KS to distort colors has been effectively reduced, leading to a very good final effect. After calibration, we won't see excessive warmth in SDR scenes or overly cool tones in HDR. However, it's worth noting the brightness characteristic. In SDR content, there are hardly any objections – the image looks very good, especially in older films, television programs, or materials from YouTube. It is much more difficult to evaluate the performance of the television in HDR. Analysis of the EOTF curve suggests correct behavior, 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 color reproduction, but certain limitations arising from the operation of local dimming and the way it is controlled by the C69KS cannot be avoided, as we also saw in the C6K test.

Upscaling and digital image processing are a true showcase of the capabilities of 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 maximum quality from lower resolution materials—whether it's television or an old DVD movie, the image looks sharper, with more details and better depth. Sure, if we feed it exceptionally low-quality material (like our archival photo with the Model), it won't work miracles, but in everyday viewing, it's hard to find anything to complain about.

The soft gradation feature also performs excellently. In the "Medium" setting, it effectively smooths tonal transitions, eliminating banding on colored and gray gradients, while simultaneously preserving film grain and fine image details. It is this balance between delicacy and effectiveness that keeps Sony TVs among the best on the market in this category.

C69KS handles upscaling quite well. The tested 576p material looks surprisingly decent – a significant amount of detail is preserved, and the algorithm adds a subtle "rounding" effect to sharp edges, making the image appear more cohesive. However, the smoothing of tonal transitions is lacking. The television practically cannot improve them, leaving the image in a somewhat raw state. With older materials, this can be simply exhausting, as the lack of additional processing highlights all imperfections.

Motion smoothness is practically a closed topic in the case of Bravia 8 II. The OLED with 120 Hz refresh rate naturally provides a very clean, clear image in dynamic scenes, so there is little to complain about. However, particular praise is due to one of the best motion smoothing systems on the market. They allow for precise adjustment of film smoothness according to one's preferences – from gentle smoothing to an almost "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 improvement panel in movies, allowing you to adjust the intensity of the effect using a slider. This makes it easy to match the smoothness to your own preferences. The possibility of using higher refresh rates is also a plus – even though the panel operates natively at 4K at 60 Hz, lowering the resolution to 1440p allows you to enable 120 and 144 Hz modes, both on consoles and PC. This sounds like great news, but in practice, the image at these settings suffers from significant motion blur. The effect is noticeable enough that the overall experience feels simply mediocre and loses its appeal in everyday use.

Sony really learned its lesson from previous years and in the Bravia 8 II prepared a package of features for gamers that is difficult to describe as anything other than "almost perfect." We have everything expected in equipment of this class – VRR, ALLM, Dolby Vision Gaming mode, HGiG, and even a convenient Game Bar that allows you to quickly preview parameters and change settings without leaving the game. Additionally, it's worth noting how smoothly and flawlessly these features work – no delays, no strange stutters. You simply turn on the game and everything looks as it should. Unfortunately, there are a few "buts." The manufacturer still gives us only two full-bandwidth HDMI ports, so if someone has a console, a PC, and another device like a Soundbar connected via eARC, it starts a game of cable swapping. It's 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 TVs that can comfortably be placed in the center of a gaming lounge, allowing you to enjoy gameplay without significant compromises.

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