Samsung Q60D / Q67D / Q68D vs TCL C6KS / C69KS / Q6CS

Television Samsung Q60D, regardless of the tested scene, achieves brightness levels above 500 nits, which is above average for this class of devices. Such a level of brightness allows for a taste of true home cinema, with clearly visible details in bright areas of the image and well-rendered contrast dynamics, especially when watching content from streaming platforms or films played from Blu-ray. This means that movie screenings gain greater depth and realism, particularly in well-lit scenes. Despite the use of quantum dot technology (QLED), the television does not achieve outstanding results in colour reproduction. The coverage of the DCI-P3 colour space is only 90%, which may be noticeable in more demanding scenes, where the richness and saturation of colours play a key role in image quality.

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%.

Samsung has been offering a "Filmmaker" mode in its TVs for several years now, aimed at providing the most faithful picture settings straight from the factory, in line with the vision of filmmakers. This is certainly a big step towards cinematic quality at home, but it is worth noting that this mode is not without its issues.

For example, the white balance in both SDR and HDR modes exhibits an excessive amount of red, which makes the image too warm. As a result, the skin tones of actors and bright scenes can appear unnaturally flushed. The Colour Checker test further confirms this problem – colour samples often shift towards red hues, deviating from the neutral colour representation that would be more desirable in a professional setup.

When it comes to contrast, there is a noticeable strong drop at the beginning of the gamma graph, where values below 2.4 drop all the way down to 2.1. As a result, the image in darker scenes may appear less distinct, losing depth. In the case of HDR content, the EOTF curve (which is responsible for brightness reproduction) shows a strong spike at the beginning of the graph, which can lead to excessive brightness in the lighter parts of the image, disrupting the natural tonal balance.

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 of the Samsung Q60D television in film mode, users can enjoy a significant improvement in image quality. Samsung televisions have always offered 2- and 20-point grayscale adjustment and an advanced CMS (Colour Management System), allowing for precise colour and shade adjustments. The white balance for both SDR and HDR has been stripped of strong peaks and tendencies towards colour drifting into red tones, significantly enhancing the naturalness of the image. Although a few larger errors can still be observed in HDR mode, the overall quality of colour reproduction has been excellently improved. Regarding contrast, although drastic changes cannot be said due to the limitations of the television's technology, the improvement is noticeable. Thanks to calibration, details in dark scenes are more visible, and the differences between light and dark elements of the image have been enhanced. This makes the overall perception of the image more satisfying, allowing viewers to enjoy greater depth and realism in the displayed content.

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.

However, when it comes to processing and scaling lower quality materials, the television performs quite well. The image is rendered without overscan, which ensures full use of the available screen space. Additionally, the outlines of the model or branches of the tree are not overly jagged, resulting in a satisfactory quality of the displayed content. Although noise reduction could be more effective, the overall processing results of lower quality materials are positive and meet expectations.

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.

Samsung Q60D is equipped with a 60 Hz panel and a feature to enhance movie smoothness, known as "Motion Blur Reduction." This function aims to minimise motion blur and improve overall image fluidity, which will certainly appeal to users who primarily seek a television for watching movies and series. Thanks to this technology, viewers can enjoy a more fluid visual experience, even in dynamic action scenes where details are crucial. However, it is worth noting that while "Motion Blur Reduction" improves image fluidity in films, for gaming, this panel may not be the best choice due to its considerable motion blur effect, which can be seen in the photo below.

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.

Samsung Q60D has been equipped with features such as ALLM (Auto Low Latency Mode), HGiG (HDR Gaming Interest Group) and Game Bar, which significantly enhance the gaming experience. However, the lack of HDMI 2.1 implementation limits its capabilities, preventing the use of VRR (Variable Refresh Rate), which could further improve smoothness and image quality. Generally, for casual gamers, this TV should perform well in everyday use, providing satisfactory gaming experiences. However, if we are more demanding in terms of gaming, it is worth considering models with a higher refresh rate and HDMI 2.1, which will ensure full functionality and better support for the latest games. In such cases, investing in a more advanced TV will yield significantly better results in terms of smoothness and image quality, which is crucial for gaming enthusiasts.

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.
