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

The Samsung Q60D consistently achieves brightness levels above 500 nits, which is above average for its class of devices. This level of brightness enhances the viewing experience, providing a more immersive home cinema feel, with clearly visible details in bright areas of the image and well-rendered contrast dynamics, especially when watching content from streaming platforms or Blu-ray discs. As a result, movie screenings gain added depth and realism, particularly in well-lit scenes.

However, despite incorporating quantum dot technology (QLED), the TV does not excel in colour reproduction. The DCI-P3 colour space coverage is limited to 90%, which may become apparent in more demanding scenes where the richness and saturation of colours are crucial for image quality. While the Q60D offers solid performance, those seeking more vibrant and accurate colour reproduction may notice some limitations.

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.

For several years, Samsung has included a "Filmmaker" mode in its televisions, designed to deliver picture settings that remain true to the original vision of filmmakers straight out of the box. This is undoubtedly a significant move towards achieving cinematic quality at home, but it's important to note that this mode is not without its drawbacks.

For instance, the white balance in both SDR and HDR modes tends to show an excessive amount of red, resulting in an overly warm image. This can cause actors' skin tones and brighter scenes to appear unnaturally pink. The Colour Checker test confirms this issue, as colour samples often shift towards red hues, deviating from the neutral colour representation that would be preferred in a professional context.

In terms of contrast, there is a noticeable dip at the start of the gamma curve, where values below 2.4 fall to around 2.1. This can make darker scenes look less detailed, diminishing their depth. When displaying HDR content, the EOTF curve (which handles brightness representation) shows a significant peak at the beginning of the graph, potentially leading to excessive brightness in lighter areas of the image and disrupting the natural tonal balance.

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 of the Samsung Q60D in film mode, users can experience a notable enhancement in image quality. Samsung TVs have long featured both 2- and 20-point grayscale adjustments, and an advanced Colour Management System (CMS), enabling precise tuning of colour and hue. Following calibration, the white balance for both SDR and HDR content is free from significant peaks and red tone shifts, resulting in a more natural image. Although a few larger errors may still be evident in HDR mode, the overall improvement in colour accuracy is impressive.

In terms of contrast, despite the inherent limitations of the TV’s technology, there has been a marked improvement. Calibration enhances the visibility of details in darker scenes and accentuates the differences between lighter and darker elements, making the image appear more dynamic. This leads to a more satisfying viewing experience, with improved depth and realism in the displayed content.

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.

However, when it comes to processing and scaling lower-quality content, the TV performs quite well. The image is displayed without overscan, ensuring the full use of the available screen space. Additionally, the edges of models or tree branches are not overly jagged, resulting in satisfactory content quality. While noise reduction could be more effective, the overall processing of lower-quality materials is positive and meets expectations.

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 Samsung Q60D is equipped with a 60 Hz panel and includes a feature known as "Motion Reduction," designed to minimise motion blur and improve the overall fluidity of the image. This addition is particularly beneficial for users who enjoy watching films and series, providing a smoother visual experience even during dynamic action scenes where detail is essential. However, while "Motion Reduction" enhances the viewing experience for cinematic content, it is important to note that this panel may not be the optimal choice for gaming due to a noticeable motion blur effect, which can become apparent during fast-paced gameplay.

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 Samsung Q60D has gaming features such as ALLM (Auto Low Latency Mode), HGiG (HDR Gaming Interest Group), and Game Bar, which contribute positively to gaming experiences by optimising response times and enhancing HDR visuals. However, the absence of HDMI 2.1 support limits the TV's potential, preventing the use of VRR (Variable Refresh Rate) which could further boost smoothness and image consistency. For casual gamers the Q60D should suffice, delivering satisfactory performance during typical gameplay. On the other hand, for more discerning gamers, models with a higher refresh rate and HDMI 2.1 support are recommended. Such upgrades enable full functionality and better compatibility with the latest games, ensuring smoother motion and superior image quality – essential for an immersive and top-tier gaming experience.

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.
