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

The Samsung Q60D television, regardless of the scene being tested, achieves brightness above 500 nits, which is above average for this class of devices. Such a level of brightness allows one to experience a taste of true home cinema, with clearly visible details in bright parts of the image and well-reproduced contrast dynamics, especially when watching content from streaming platforms or movies played from Blu-ray. As a result, film 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 has become a recurring theme of 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 keep in mind 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 blacks. This is quite a reasonable compromise. Most viewers will definitely appreciate deep, "true black" more than additional micro-details, the display of which could cause the screen to appear greyed out. This is the nature of local dimming technology in this price range, and one must be aware of it. It is also worth noting that the TCL C69KS (C6KS) has an additional PFS coating, which is marketed under the slogan of QLED technology. 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% here.

Samsung has been offering a "Filmmaker" mode in its televisions for several years, aimed at providing the most faithful picture settings straight from the factory, in accordance with the vision of filmmakers. This is certainly a significant step towards cinematic quality at home; however, it is worth noting that this mode is not without its problems.

For instance, the white balance in both SDR and HDR modes exhibits an excessive amount of red hue, causing the picture to appear too warm. As a result, the skin of actors and bright scenes may seem unnaturally pinkish. The Colour Checker test further confirms this issue – colour samples often shift towards red tones, deviating from the neutral colour reproduction that would be more desirable in a professional setting.

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

Unlike the more expensive C6K model, the tested C6KS does not have an option in the menu labelled as Filmmaker Mode. Is this a reason to cry? Absolutely not. Our tests have shown 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 characteristic 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 gives 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 grey scale adjustments, as well as an advanced CMS (Color Management System), which allows for precise colour and shade adjustments. The white balance for both SDR and HDR has been free from strong spikes and tendencies for colours to shift to red hues, greatly enhancing the naturalness of the image. Although a few more significant errors can still be observed in HDR mode, the overall colour reproduction quality has been excellently improved. Regarding contrast, although drastic changes cannot be mentioned due to limitations in 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 viewing experience 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, resulting in a very good final effect. After calibration, we will no longer see excessive warming of scenes in SDR or overly cool tones in HDR. However, it is worth noting the brightness characteristics. In SDR content, it is hard to have any objections – the image looks very good, especially in older films, television programmes, or materials from YouTube. It is significantly more challenging to evaluate the television's performance in HDR. Analysis of the EOTF curve suggests correct behaviour, but its practical variant reveals certain limitations. The C69KS can overly brighten the smallest elements of the frame, while at other times, it can dim the entire scene. Thus, calibration brought clear benefits in terms of colour quality, but certain limitations resulting from the local dimming operation and the way it is controlled by the C69KS cannot be overlooked, as we also saw 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 area. Additionally, the outlines of the model or the branches of the tree are not overly jagged, which translates to a satisfactory quality of the displayed content. Although noise reduction could be more effective, the overall results of processing lower quality materials are positive and meet expectations.

The C69KS handles upscaling quite well. The tested 576p material looks surprisingly decent – a considerable amount of detail is retained, and the algorithm adds a slight "rounding" effect to sharp edges, making the image appear more cohesive. The performance in smoothing tonal transitions is less impressive. The television practically cannot improve them, leaving the image in a rather raw state. With older material, this can be quite tiring, as the lack of additional processing highlights any imperfections.

Samsung Q60D is equipped with a 60 Hz panel and a film smoothness enhancement option known as "Motion Blur Reduction." This feature aims to minimise motion blur and enhance overall image smoothness, which will certainly appeal to users who are primarily looking for a television to watch films 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 the smoothness of images in films, for gaming, this panel may not be the best choice as it exhibits significant motion blur, which can be seen in the picture below.

C69KS offers a simplified motion enhancement panel in films, allowing the adjustment of effect intensity with a slider. This makes it easy to match fluidity to personal preferences. The ability to use higher refresh rates is also a plus – although the panel operates natively at 4K at 60 Hz, lowering the resolution to 1440p enables 120 and 144 Hz modes, both on consoles and PC. This sounds like great news, however, in practice, the image at these settings exhibits significant motion blur. The effect is so pronounced that the overall presentation appears merely average and loses its appeal for everyday use.

Samsung Q60D is 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 capabilities, preventing the use of VRR (Variable Refresh Rate), which could further improve smoothness and picture quality. Overall, for casual gamers, this television 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 television will yield significantly better results in terms of smoothness and picture quality, which is crucial for gaming enthusiasts.

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