Philips OLED769 vs TCL C6KS / C69KS / Q6CS

Philips OLED769 performs quite well, especially in movie scenes with small light points. The television surprises with its brightness, reaching around 800 nits, which is an impressive result. This means that small light sources, like street lamps at night or stars in the sky, are vivid and full of detail. However, the biggest challenge for this model is the scene with a full-screen sun glare. In such moments, the brightness drops to around 250 nits, which isn’t very impressive. This is a typical issue with cheaper OLED displays, which struggle to maintain high brightness across the entire screen.

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 "Film" mode turned out to be the best factory setting in terms of fidelity to the original material, and it was on this setting that we based our tests. However, like other factory modes, it was not without its flaws. Let’s take a closer look at what exactly went wrong in the SDR and HDR materials.

In both cases, the white balance was disturbed by excessive dominance of green and red colours. This phenomenon created a yellowish tint that spilled over the entire image, leading to issues such as yellowed whites and unnatural skin tones. These problems were clearly highlighted on the "ColourChecker" palette, where each of the samples was shifted towards warmer shades.

As for contrast and brightness, in the Philips OLED769, we can look at two key graphs: Gamma for HD content and the EOTF curve for 4K HDR content. In the case of the first graph, the gamma value is below the optimal level of 2.4, resulting in the bright parts of the image being lightened. This means that bright elements may be somewhat overexposed, losing detail and depth. Meanwhile, the EOTF curve for 4K HDR content performs really well. The graph shows that the television effectively reproduces details in both the brightest and darkest parts of the image, translating to a realistic and dynamic representation of scenes.

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 professional calibration, Philips OLED769 truly shines in terms of colour accuracy. The television has been completely rid of any yellow tint in both HD and 4K content. The Colour Checker test confirms that deltaE errors are minimal, occasionally exceeding 2, which means we can talk about almost perfect renderings of the director's vision.

When it comes to contrast, the situation is equally impressive. For 4K materials, there wasn't much to improve from the start, while the gamma graph has been significantly enhanced. As a result, dark and bright parts of the image are represented with greater accuracy, leading to realistic and dynamic scene reproduction.

The calibration has unlocked the full potential of this television, both in terms of colour and contrast. Philips OLED769 now offers vivid, natural images of high quality that will delight any user, whether they're watching movies or using other multimedia.

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.

When it comes to lower quality materials, the distortion reduction in the Philips OLED769 does well at smoothing tonal transitions, especially at the minimum setting. It's worth noting that at this setting, film grain isn't blurred, which is a pleasant surprise, as such negative phenomena often occur with other manufacturers. Overall, it's quite a decent solution. However, it should be noted that this setting doesn't work in HDR mode, where gradation issues are much more pronounced. In HDR mode, the television struggles with smoothing tonal transitions and may present more noticeable distortions and noise, reducing image quality in dynamic scenes.

As for digital processing, the Philips OLED769 performs well. The model in the picture isn’t overly jagged, and the branches in the background lack the characteristic artifacts. The television achieves this effect by avoiding artificial sharpening, which may be an advantage for some users. However, others may find this less appealing, as they prefer a more vivid, sharper image rather than a subtle effect. This effect can be mitigated by using a higher setting for the "Sharpness" parameter.

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.

Philips OLED769 features a multi-level motion smoother called "Motion Style," which will please users who value the ability to adjust motion fluidity in films. With this function, the image can be set to appear more stuttery or fluid, reminiscent of a theatrical effect. It's a great solution for those who want to tailor the displayed content to their visual preferences. Gamers will also not be disappointed, as the television, like most OLEDs, is equipped with a 120Hz panel. This ensures extraordinary fluidity and dynamic imagery. Unfortunately, Philips OLED769 does not have the BFI (Black Frame Insertion) feature, which could further enhance the smoothness and clarity of motion. Despite this limitation, the television still offers excellent visual experiences for both cinema lovers and gamers. This is definitely one of its strong points.

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.

Philips OLED769 has been designed with gamers in mind, offering full compatibility with consoles and the highest quality gameplay. The television received the maximum rating in this category, providing everything your heart desires. With HDMI 2.1 ports fully supporting ALLM (Auto Low Latency Mode) and VRR (Variable Refresh Rate), the TV ensures smooth and hassle-free gaming. ALLM automatically switches the television to low latency mode, and VRR eliminates stuttering and screen tearing, resulting in smoothness and stability in gameplay. The Dolby Vision feature for gamers is another advantage, although it only works at 60 Hz. Most casual gamers will probably not feel the lack of a higher refresh rate, however, more demanding users may have some reservations. It allows for enjoying a dynamic range of tones and realistic images, enhancing the gaming experience. PC gamers will also not be disappointed, as the Philips OLED769 offers full compatibility with Nvidia graphics cards, thanks to support for G-Sync. This technology synchronizes the TV's refresh rate with the graphics card, eliminating tearing and stuttering, leading to excellent image smoothness.

Philips OLED769 is a television that perfectly meets the needs of gamers, offering a wide range of advanced features and technologies that significantly enhance game quality and user comfort.

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.
