Sony Bravia 7 (XR70) vs TCL C6KS / C69KS / Q6CS

Now that we know the TV handles contrast well, let’s check how it performs in terms of HDR effects. The luminance graph shows very high capabilities for this model – 1500 nits is truly an impressive result. HDR effects are particularly striking in scenes where most of the screen is covered in light, such as in the 1st, 3rd, and 5th test scenes. Minor imperfections, typical of this technology, are still visible with very small light effects, as seen in the scene from the film "Sicario 2," where brightness drops to 500 nits. Although these aren't staggering results, they can be considered decent. Additionally, it's worth praising the TV for its high coverage of a wide colour gamut – DCI-P3 at 96%, which allows for vibrant, saturated colours.

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%.

The IMAX Enhanced mode on the Sony BRAVIA 7 TV is definitely the best mode available on this model, although it is not without its flaws, as its name might suggest. The biggest issue is white balance – both in HD and 4K HDR content, there is a noticeable dominance of the red colour, which causes the image to take on pinkish hues. This is particularly evident on the test image with snow, where the pinkish tint becomes very noticeable. Errors in the Colour Checker test also confirm these deviations – although they are not catastrophic, there is a tendency to lean towards warmer tones. In terms of brightness characteristics, the gamma remains at a decent level with a slight spike but without major issues. However, the biggest challenge is with 4K material. It is clear that the EOTF curve is significantly above the reference graph, making the image appear overly bright.

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.

Sony BRAVIA XR70 offers a wide range of tools that allow you to customise the image to your own preferences, enabling significant adjustments to the settings. White balance has been freed from the red colour dominance issue – snow no longer takes on pink hues, which was previously noticeable. Although there are slight deviations in the final part of the white balance chart regarding a drop in blue colour, they are acceptable and difficult to notice in everyday use. The Colour Checker test confirms that colour reproduction errors are no longer as pronounced and rarely exceed a value of 2, which is a very good result. As for brightness, gamma, although it didn't require major improvement, has been slightly adjusted. However, the most significant change has been noted in the EOTF curve – the television no longer has issues with excessively brightening the entire image in 4K materials. However, upon closer examination and incorporating the EOTF characteristics in film materials, some limitations of the television become apparent due to the previously discussed dimming algorithm. Some small elements may be slightly more illuminated, but these errors are minor enough that most users won't notice them. Overall, the calibration results are very, very positive.

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.

Since we know that the television handles high-quality content very well, it's worth checking how it performs with lower-quality material. Here, the television shows its potential, and the graphics processor used works remarkably well. On the test screen with the light bulb, there are no issues with colour blending, and the gentle gradation function works very well – we recommend setting it to "Medium".

When it comes to digital processing, or the so-called upscaling, the television sharpens the image quite significantly, which leads to a slight jaggedness, for example on branches in the background, but it doesn't remove desired details. Despite this, the overall appearance is really attractive and may appeal to most users. However, if you prefer a softer, more plastic image, you can reduce this effect in the settings by adjusting the sharpness level to your liking.

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.

The Sony BRAVIA 7 TV with a 120 Hz panel will satisfy most users in terms of motion fluidity. Additionally, Sony offers a Motion Flow feature that allows for the selection of three different picture settings, adjusting them to personal preferences: Smoothness – Film: This setting improves motion fluidity, giving the image a more cinematic or theatrical quality. Smoothness – Camera: This setting provides even greater fluidity, useful for watching dynamic scenes like sports broadcasts. Clarity: This setting focuses on minimising noise and motion artifacts, resulting in a more stable and clear image.

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 Bravia 7 has significantly improved its capabilities in terms of compatibility with consoles compared to earlier models. The TV supports variable refresh rate (VRR), which eliminates screen tearing, and it syncs with graphics cards to ensure smooth display. The automatic low latency mode (ALLM) effectively reduces input lag, which is crucial in dynamic games. Dolby Vision with low latency further delivers impressive HDR effects that look great during gameplay.

Sony Bravia 7 also offers a Game Bar feature, providing quick access to settings and monitoring parameters while gaming. An interesting option is the ability to enable a virtual on-screen reticle, which can give a slight advantage in shooter games. However, compared to the Bravia 9 model, the HGIG feature in the Bravia 7 doesn't perform as well, which may be noticeable for more demanding gamers – particularly as the HGIG mode is becoming increasingly popular among gamers as the preferred method for reproducing HDR effects.

A downside is the lack of support for 1440p@120 Hz resolution, which could make gaming easier for users with less powerful graphics cards. Additionally, the Sony Bravia 7 is equipped with two HDMI 2.1 ports, one of which is often used to connect an audio system via eARC, limiting the number of available ports for connecting next-gen consoles.

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.
