Philips OLED769 vs TCL C6KS / C69KS / Q6CS

The Philips OLED769 performs admirably in film scenes featuring small bright elements. With peak brightness reaching around 800 nits, the TV handles light sources like street lamps or stars with remarkable vividness and detail. However, its limitations become evident during scenes with full-screen brightness, such as sun glare, where brightness drops to approximately 250 nits. This is a common challenge for more affordable OLED models, which often struggle to sustain high brightness across the entire display.

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.

The "Film" mode on the Philips OLED769 proved to be the most faithful factory setting for preserving the source material, and it was the basis for our tests. However, like other factory presets, it has a few flaws. Let’s break down the key issues observed in SDR and HDR content.

In both formats, the white balance exhibited a noticeable dominance of green and red tones. This led to a yellowish tint across the image, resulting in yellowed whites and slightly unnatural skin tones. This was particularly evident in the "ColourChecker" palette, where colour samples leaned toward warmer shades.

In terms of contrast and brightness, two critical graphs tell the story: the Gamma curve for HD content and the EOTF curve for 4K HDR content. For SDR, the gamma value dips below the ideal 2.4 level, causing lighter parts of the image to appear overly bright. This overexposure reduces detail and depth in bright areas. In contrast, the EOTF curve for HDR content performed admirably, accurately maintaining details in both bright and dark regions. This ensures realistic, dynamic scene reproduction that enhances the overall viewing experience.

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 professional calibration, the Philips OLED769 truly excels in colour accuracy. Any yellow tint previously seen in HD and 4K content is now eliminated. The Colour Checker test shows minimal deltaE errors, occasionally exceeding a value of 2, which indicates a nearly perfect representation of the director's intent.

When it comes to contrast, the results are equally impressive. For 4K materials, there was little room for improvement initially, but the gamma curve has been significantly refined. This leads to a more accurate rendering of dark and bright areas, resulting in a dynamic and realistic viewing experience.

Thanks to the calibration, the full potential of the television has been unlocked. The Philips OLED769 now delivers vibrant, natural, and high-quality images, making it an excellent choice for movie lovers and multimedia users.

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.

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

As for digital processing, the Philips OLED769 performs well. The model in the photo is not overly jagged, and the branches in the background lack characteristic jagged edges. The TV achieves this effect thanks to the absence of artificial sharpness, which may be an advantage for some users. However, others may find this less attractive as they prefer a more pronounced, sharper image instead of a subtle effect. This effect can be mitigated using a higher setting for the "Sharpness" parameter.

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.

The Philips OLED769 features a multi-stage motion smoother called "Motion Style," which will satisfy users who value the ability to customize motion fluidity in movies. Thanks to this function, the image can be set to be more frame-like or fluid, resembling a theatrical effect. This is a great solution for those who want to match the displayed content to their visual preferences. Gamers will also be pleased, as the TV, like most OLEDs, is equipped with a 120Hz panel. This provides extraordinary fluidity and image dynamics. Unfortunately, the Philips OLED769 lacks BFI (Black Frame Insertion) functionality, which could further improve motion fluidity and sharpness. Despite this limitation, it offers excellent visual experiences for cinema and gaming enthusiasts, one of its main strengths.

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.

The Philips OLED769 was created 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 one could desire. With HDMI 2.1 ports fully supporting ALLM (Auto Low Latency Mode) and VRR (Variable Refresh Rate), the television ensures smooth and hassle-free gaming. ALLM automatically switches the TV to low latency mode, and VRR eliminates stuttering and screen tearing, resulting in fluidity and stability in gameplay. The Dolby Vision feature for gamers is another advantage, though it only works at 60 Hz. Most casual gamers are unlikely to feel the lack of a higher frequency, but more demanding users may have some reservations. This 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, translating to excellent image smoothness.

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

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.
