Samsung Neo QLED QN85D / QNX1D vs TCL C655 Pro

Samsung QN85D leaves us with mixed feelings regarding HDR quality. It can shine in synthetic luminance tests, reaching even 1000 nits – which makes scenes like those from 'The Meg' or the start of 'Life of Pi', where the screen is all bright, look truly impressive. However, in practice, the device has its limitations – especially when smaller bright elements appear on the screen. In such moments, brightness noticeably drops, and the HDR effect loses its punch. At brightness levels around 200-300 nits, the magic of HDR simply fades away, not delivering spectacular effects. However, it’s not that the television completely disappoints – coverage of the DCI-P3 colour gamut at 95% is quite decent, although it doesn’t stand out against the best competitors. Colours are well-rendered, but it's clear that HDR could make a bigger impression if brightness could be better controlled.

In the HDR effect quality category, the television TCL 655 PRO shows decent capabilities, achieving 550 nits of peak brightness. This allows for enjoying HDR effects, which can be clearly seen in scenes such as the first one from the movie Life of Pi or the final shot from The Meg. However, the limited number of dimming zones causes some issues. While in bright scenes the television performs better than its lower model, in more demanding scenes, such as the second and fourth scenes from Sicario 2, it struggles more. The dimming algorithm aims for deep blacks, but at the cost of brightness – which at those moments can cause a drop in brightness of even half. In these more challenging scenes with small elements, it's hard to find any praise, and the HDR effect resembles SDR. Nevertheless, the coverage of the colour palette deserves recognition, which, like in the version without the PRO suffix, is at a very good level.

Samsung QN85D TV has been tested in the best available mode – Filmmaker. While one might expect its name suggests a mode perfectly suited for films, unfortunately, it has several significant issues.

When it comes to white balance for HD content, there is a noticeable dominance of red and blue, which makes the entire image take on pinkish hues – this is also confirmed by Colour Checker tests. This effect disturbs the naturalness of skin tones and many other elements, which is particularly evident in more demanding scenes. Initially, the white balance for 4K HDR content seems correct, but at the end of the graph, there is a significant spike in blue hues, affecting the final image quality and making the colours appear unnatural.

The gamma brightness characteristic is also not ideal – although it generally stays close to the reference value, there is a slight drop below 2.4, which can impact the perceived depth of shadows. The EOTF curve responsible for 4K content does not perform any better. There is a clear boost compared to the reference curve, leading to excessive brightness in some areas, thus losing the cinematic quality that the Filmmaker mode should provide. While it might initially seem that the effect is cinematic, unfortunately, the number of errors in colour and brightness reproduction is too significant to call it flawless.

Each of our TV tests is conducted in movie mode, which usually offers the best colour reproduction. However, even this mode is not free from issues, as we noted in the TCL 655 PRO model.

In the case of HD content, the white balance clearly shifts towards red, and this effect becomes particularly noticeable in a scene from Star Wars, where the white elements of the scenery take on a pink hue. For 4K HDR material, the situation looks better, but there is a tendency to overly emphasise the colour blue. As a result, the image can give a sense of artificial sharpness, which proves to be uncomfortable for the eyes over a longer period. The brightness characteristics also leave much to be desired. The Gamma chart indicates serious difficulties with excessive brightening, making the overall presentation appear washed out. Additionally, the EOTF curve reveals significant problems with reproducing very small elements – they are overly dimmed, as we have detailed in the paragraph regarding HDR effects.

After professional calibration of the Filmmaker mode on the Samsung QN85D television, a significant improvement is noticeable, especially for HD/SDR content. The white balance has been completely free of major errors, and the brightness characteristics for this type of content have been significantly adjusted, allowing for a more natural and realistic image. Television, YouTube films, and other HD materials now look much better, with appropriately balanced colours and without the exaggerated hues that previously marred the experience.

However, the biggest issues arise with 4K HDR content. Despite the calibration, it's hard to speak of significant improvement in white balance here – the differences are cosmetic rather than essential. Brightness, governed by the EOTF curve, seems to be set according to the reference level in synthetic tests at first glance, but has its limitations during actual viewing in films. When analysing the EOTF curve in real film scenes, it becomes clear that the television struggles to maintain consistency in brightness. The effect is that mixed scenes still have their darkest elements boosted, leading to exaggerated contrasts, and completely dark scenes remain too dark, which negatively affects the visibility of details.

After calibrating the TCL 655 PRO television, there is a noticeable improvement in white balance, where the tendency for the screen to be overly pink has been completely eliminated, which was previously noticeable in factory mode. The picture has taken on more natural tones, especially in white and bright elements, which positively affects the overall image perception. Regarding brightness characteristics, the Gamma chart has also improved – the screen is no longer excessively bright, which previously made the image appear washed out. Nevertheless, there are still some issues with the EOTF curve, which are difficult to eliminate due to the television's construction and its limited number of backlight zones. These limitations prevent achieving perfect results in this regard. However, despite this minor fault, the overall effect after calibration is truly outstanding, providing high picture quality and very good colour reproduction.

When checking the fluidity of tonal transitions in low-resolution materials on the Samsung QN85D television, it’s worth noting the noise reduction feature, which significantly improves problematic tonal transitions. On the other hand, this feature also has its downsides – it removes film grain, which is an important element of many productions, giving them authenticity, and it can also soften the image. This may appeal to those who prefer a smoother picture; however, for lovers of the authentic look of films, using this feature should be considered carefully.

Regarding image scaling, the television performs very well. The model's figure is presented correctly, without noticeable distortions, and the branches in the background do not have excessive artificial sharpness, which is often a problem when scaling lower resolution materials. The high capabilities of the image processor are evident here, which can effectively process lower quality materials, ensuring good final quality.

The TCL 655 PRO television handles tonal transitions quite well in lower-quality material. The "Gradual Smoothing" feature at low settings effectively smooths tonal transitions, but this comes at the cost of losing some essential details, such as the texture of objects. On the plus side, it doesn't negatively affect film grain, which helps maintain a natural look to the image.

In the context of digital processing, the television adds artificial sharpness. This may appeal to users who prefer a bolder image. However, individuals who favour a softer, more subtle look may find this a drawback. Additionally, a downside is the image cropping due to overscan, which limits the field of view and cuts off the edges of the frame. This can be problematic in certain scenes - for example, news tickers.

Samsung QN85D TV is equipped with a 120 Hz refresh rate panel, which should satisfy both gamers and sports enthusiasts by offering a smooth and dynamic image. There are options to enhance fluidity, such as the blur and judder reduction feature, which allows precise motion fluidity adjustments on a 10-point scale. The blur reduction increases the sharpness of fast-moving objects, making action scenes more readable, while judder reduction smooths out motion, eliminating the “judder” effect. Ghosting is generally well controlled, though minor imperfections can be visible in more demanding scenes, especially when an object moves against a dark background. Additionally, the TV offers a BFI (Black Frame Insertion) feature at a 60 Hz refresh rate, which can significantly improve motion fluidity experience, although at the cost of image flicker, which might be bothersome for some users.

The TCL C655 PRO television is equipped with a 4K display with a refresh rate of 60 Hz, making it ideal for watching movies. Additionally, the "Flicker Reduction" feature allows for adjusting the smoothness of the picture, giving the user the choice between smoother motion and a cinematic, frame-by-frame effect. Furthermore, the television performs well with lower resolution content, such as Full HD and 2K, offering a refresh rate of 120 Hz, which will surely appeal to gamers who can enjoy a smoother image, albeit at the cost of lower resolution.

The Samsung QN85D television is an excellent choice for gamers, offering a wide range of features that enhance the gaming experience and make it even more exciting. With a 120 Hz refresh rate panel, the image is incredibly smooth, which is crucial during dynamic scenes in action games. The television also boasts low input lag, allowing for nearly instant reactions to player commands, which translates into better control over characters and events on the screen.

In addition, the QN85D Samsung supports VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode) technologies, which optimise image smoothness and reduce delays by automatically adjusting the television to the needs of gamers. Moreover, the Xbox app allows for cloud gaming without the need for a console, which is a big plus for those who want to enjoy their favourite titles without additional hardware – a feature that sets Samsung televisions apart.

The Auto Motion Plus Game feature is another aspect worth highlighting. This motion smoothing technology creates the illusion of more frames per second – as a result, games at 30 fps appear smoother, resembling gameplay at 45 fps, while games at 60 Hz come closer to 90 Hz. Most importantly, this feature does not introduce significant lag, ensuring that gaming comfort is not compromised. This allows gamers to enjoy a smoother image without compromising responsiveness.

The TCL C655 PRO TV offers an almost perfect set of features for gamers, supporting all key technologies that significantly enhance gameplay comfort. The ALLM feature automatically switches the TV to low-latency mode, improving responsiveness and minimising signal delay – particularly important in fast-paced titles. VRR synchronises the screen refresh rate with the frame rate generated by the console, eliminating screen tearing and ensuring smoother gameplay.

Support for Dolby Vision in game mode enables more detailed colour and contrast representation in games that support this format, while the Game Bar provides quick access to essential settings, such as response time and latency level. Unfortunately, the model does not support 4K resolution at 120 Hz, which may disappoint the most demanding gamers. However, for those willing to forgo 4K, support for Full HD and 2K at 120 Hz offers exceptionally smooth visuals, making it an attractive alternative for high refresh rate enthusiasts.
