TCL P755 vs Samsung Q60D / Q67D / Q68D

TCL P755 provides average HDR effect quality. The maximum brightness of the TV is slightly below 300 nits. Such brightness limits the intensity of bright areas in HDR content. In practice, this means that bright elements may not be sufficiently pronounced, affecting the overall impression of contrast. However, the TV offers wide coverage of the DCI P3 colour gamut, reaching about 93%. As a result, colours are vibrant and saturated, significantly improving colour reproduction quality in HDR content. Despite the limited brightness, the wide colour range allows for richer and more realistic shades.

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.

The colour reproduction in the P755 in "Cinema" mode, although it is the best factory setting, leaves much to be desired. The biggest issue is the white balance, where the chart clearly shows a spike in the red colour and a drop in the green colour. This leads to a shift in colours towards red, causing the colours on the screen to appear less natural and may look incorrect, especially in scenes with a white or neutral background. This is confirmed by the "Colour Checker" test, which reveals that the colours are indeed shifted towards red, affecting the realism of the image and reducing the perception of colour depth. In terms of contrast, the gamma chart analysis shows significant fluctuations, particularly in the dark areas of the image, where values drop below the optimal level of 2.4. As a result, darker areas may be displayed brighter than they should be. Additionally, the EOTF curve, responsible for brightness reproduction, sits slightly above the reference curve. The graph shows a slight increase in brightness to about 50%, after which there is only a minor drop. This leads to excessive brightness enhancement in the mid-range of the image and may result in loss of detail and distortion in brighter scenes.

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.

After calibration, the colour reproduction on the television significantly improves when it comes to SDR content. The colour curves are now close to the ideal value, and the gamma is more stable. Although the dip at the beginning of the graph to the values is still present, the overall accuracy of colour reproduction is much better. The “Colour Checker” test shows that most colour samples have errors below level 2, indicating improved colour fidelity. A few deviations are present, but generally, the colours are now more realistic and consistent with reality.

Calibration also brings improvements in HDR content. The white balance has been corrected, translating to more natural colour reproduction. The EOTF curve, although now closer to the reference curve, still shows a slight boost in brightness at the beginning of the graph. This leads to minor distortions in very bright scenes, but the overall tonality and detail have been enhanced. Dynamic tone mapping works more effectively, improving image quality in bright areas and preserving more details.

Although the image from the device does not achieve full perfection, calibration brings significant improvement. After adjusting the settings, the television performs much better, offering more realistic and accurate colour reproduction in SDR and HDR content. While some shortcomings can still be noticed, calibration effectively eliminates many previous issues, ensuring better image quality and more natural colours.

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.

The “Gradual Smoothing” function works quite well, effectively eliminating visible boundaries between different shades of the same colour. Thanks to it, tonal transitions are smoother. Unfortunately, this function is not available in HDR mode, which can affect the quality of tonal gradation in higher dynamic range materials.

In the case of image scaling, the television does not perform its best. There are noticeable edge cut-offs, particularly evident on the model's figure and the branches of trees. The blurring of details in these areas affects the overall sharpness of the image. This may be noticeable when watching content in a lower resolution. Additionally, SD quality image is displayed with slight cropping at the top as well as the bottom.

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 television offers decent, though not perfect, results in terms of motion smoothness. In the case of movies, the television has a "Flicker Reduction" feature that allows for adjustment of motion smoothness on a scale from 1 to 10. With this option, we can tailor the image appearance to cinema or more theatrical preferences (with lower or higher speed).

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.

The device offers a range of features useful for gamers, such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), Dolby Vision for gamers, and Game Bar. ALLM automatically switches the TV to low latency mode, significantly improving responsiveness to commands from the controller and minimising input lag. VRR synchronises the screen refresh rate with the number of frames generated by the console, eliminating the tearing effect and providing smoother gameplay. Dolby Vision for gamers enhances picture quality by offering better colour and contrast reproduction in games that support this format. The Game Bar feature allows quick access to game settings and monitoring of key parameters such as response time.

However, the TV has some limitations. The 60 Hz panel prevents the display of signals with higher refresh rates at different resolutions, which may affect the fluidity of the image in dynamic games. Additionally, the lack of support for G-Sync technology for PC may impact the quality of gameplay on a computer. It is also worth noting that the HGiG mode, which aims to improve image quality in HDR games, does not work correctly on this model, negatively affecting the visual experience in HDR-supported games.

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.
