Samsung Q60D / Q67D / Q68D vs TCL C655 / C69B (43" - 50")

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.

The quality of the HDR effect in the TCL C69B / C655 television is quite average. A brightness level of 350 nits, while not the worst, still does not allow for fully enjoying HDR effects, which require higher luminance to show their strength. Additionally, despite the use of a quantum dot coating (QLED), the television offers average coverage of the wide DCI-P3 color gamut at 91%, which may limit its richness of colors in HDR content.

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.

The television TCL C69B / C655 tested in movie mode unfortunately does not meet expectations regarding color accuracy. Although movie mode suggests better reproduction, it has little in common with film. There are quite a few errors visible, especially in white balance – both for HD and 4K HDR content – where the dominance of the blue color is very apparent. For the viewer, this means that the image becomes unnaturally cool, affecting the overall perception of colors and the visual impression. The color checker confirms these errors, showing that colors shift to cooler shades.

As for brightness characteristics and the associated contrast, gamma is very unstable for material, which can make the image slightly darker. The EOTF curve for 4K material shows some errors, with significant deviations at the end of the chart, negatively affecting the perception of darker areas of the image.

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.

After calibration, the movie mode on the TCL C69B / C655 television improves in quality. The most significant improvement can be seen in tonal quality, and the white balance is much better – without major errors. We will no longer see an excessive dominance of cool tones. Gamma has also been improved, which translates to a more stable representation of brightness and contrast. However, due to the limitations of the television's average color palette, Colour Checker tests for 4K materials did not achieve remarkable results. Despite these technological limitations, the image has become more authentic, positively influencing the reception of film content.

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.

The "Gradual Smoothing" function works very well on the TCL C69B television and, surprisingly, does not remove desired effects like film grain – unlike some solutions from other manufacturers. Unfortunately, the image scaling looks poor. The TV artificially sharpens the image, causing the edges of objects to be heavily jagged. This state of affairs may appeal to some users who prefer a more "hard" look of the image, but it is not an ideal solution for those who value naturalness and the smoothness of details.

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.

The TV TCL C69B / C655 in its smallest variants offers decent, although not perfect, results in terms of motion fluidity. In the case of movies, the TV has a "Flicker Reduction" function that allows for motion fluidity adjustment on a scale from 1 to 10. With this option, we can adjust the appearance of the image to cinematic or more theatrical preferences (with lower or higher speed).

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.

The TCL C69B / C655 television in its smallest variants offers a range of features dedicated to gamers, such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), Dolby Vision for gamers, and Game Bar. ALLM automatically switches the television to low latency mode, improving responsiveness and minimizing delays in control. VRR allows for synchronization of the screen refresh rate with the number of frames generated by the console, eliminating tearing, resulting in smoother gameplay. Dolby Vision for gamers ensures better color and contrast representation in games that support this format, resulting in better image quality. Meanwhile, Game Bar provides quick access to game settings and allows monitoring of key parameters, such as input lag.

However, the television has certain limitations that may affect gaming comfort. The 60 Hz panel does not allow for displaying signals with a higher refresh rate, which may impact image smoothness in dynamic games. The lack of support for G-Sync technology for PCs may also be noticeable when gaming on a computer, especially with demanding, fast-paced titles.
