Samsung Q60D / Q67D / Q68D vs TCL C75B

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.

During our luminance test, the TCL C75B "spat out" about 380 nits of brightness. We recorded similar results while watching most of the films we tested. These can be considered average – the television does not perform badly in this segment, but around 400 nits is definitely too low to fully experience the magic of HDR effects. Of course, such results are better than those of budget models, which can achieve nearly half as low brightness values. However, for HDR enthusiasts seeking stronger light effects and greater realism, the C75B may prove insufficient. On the plus side, it's worth mentioning the 95% coverage of the DCI-P3 color palette. This is a very good result that easily suffices to enjoy a wide range of colors in content available on popular streaming platforms. Vivid and rich colors are definitely a strong point of this model.

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.

TCL C75B offers many picture modes, but in our opinion, the best choice is the "Film" mode. Although its settings are quite good, the television struggles with certain color reproduction issues. In tests, we noticed that the image had a noticeably pinkish tint compared to what could be considered correct. This effect was particularly noticeable in skin tones, which appeared unnaturally warm. The main culprit of this phenomenon turned out to be the white balance, characterized by an excessive amount of blue and red in both HD and 4K HDR materials.

Another issue was the way brightness was reproduced. The gamma, which is responsible for the visibility of details in darker materials, was definitely boosted, causing details in the darkest parts of the screen to be invisible, lost in total blackness (e.g., the bottom part of the screen in the comparative photo - the area around the actress's ear). Similarly, the situation was reflected in the EOTF curve, which was below the correct value, suggesting that a similar problem may be encountered in 4K HDR content.

Thanks to our experience and the appropriate tools, we decided to take matters into our own hands and see how much could be extracted from this model after professional calibration. Details are described in the next section.

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 calibrating the TCL C75B, it has clearly improved in terms of color reproduction. Although the TV does not offer many options for adjusting the white balance, we were able to refine its settings significantly. As a result, the image has stopped being overly pink, and the colors now look much more natural and harmonious.

The gamma jump, which was previously a problem, has not disappeared completely, but we managed to significantly reduce it. This has made the details in dark scenes more visible – both in HD and 4K HDR material.

Unfortunately, the lack of local dimming is still noticeable. The "glowing black" effect remains, but that's a limitation of the display itself. Despite this, the colors after calibration look vastly better, and the image is much more enjoyable to watch.

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 TCL C75B has a tonal transition smoothing feature, but unfortunately, we can't praise it. Regardless of the selected level – low or high – tonal transitions in older materials remained visible, as if the feature didn't work at all. It's hard to say something positive about it because, in practice, it seems completely useless.

The image scaling is better. The TV performs quite decently, although on thinner elements, like branches in the background, you can notice slight halos. However, this is not something that significantly interferes with daily viewing.

Unfortunately, a bigger problem turned out to be overscan, which is the trimming of the image edges. In our tests, it happened that news tickers or other elements close to the edge of the screen were cut off. This is definitely something worth paying attention to, especially if we use the TV for watching news programs or content with text on the screen.

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.

TCL C75B definitely has something to offer gamers. The TV is equipped with a panel that can display images with a refresh rate of 144 Hz in 4K, and even 240 Hz in Full HD. These are really great results, especially for a model from the budget range.

Additionally, there are features for improving smoothness and reducing motion blur in films. The "Motion" option allows for precise adjustment of the effect on a 10-step scale, providing a lot of customization options – everyone can set the smoothness to their liking.

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 C75B is undoubtedly a television designed for gamers. It offers almost everything that the most demanding console users need. With the implementation of full-bandwidth HDMI 2.1, the television supports features such as ALLM (automatic low latency mode) and VRR (variable refresh rate) – operating across the full capabilities of the TV, up to 240 Hz in Full HD resolution.

Additionally, the television supports advanced HDR technologies, including Dolby Vision and HGiG, which allows for even better detail representation in HDR-optimized games. The C75B is also equipped with a very convenient interface for gamers in the form of a Game Bar, where you can check all key parameters, such as refresh rate, input lag, or picture settings – all within one click's reach.

In a nutshell: the C75B is an excellent choice for gamers, offering a wide range of features that allow for fully enjoying the capabilities of modern consoles and games.
