Samsung DU8002 (IPS) vs TCL C655 Pro

The HDR effect in the DU8002 television leaves much to be desired. A brightness level of 300 nits is not able to provide a true high dynamic range experience, making the content viewed resemble more of a standard SDR than impressive HDR. Scenes that should dazzle with brightness and detail appear muted and lacking in depth. Nevertheless, the television deserves praise for its high coverage of the DCI-P3 color palette at 92%. As a result, the colors are vivid and saturated, which may satisfy viewers who prefer rich hues, even if the HDR effect does not fully meet expectations.

In the HDR effect quality category, the TCL 655 PRO television shows decent capabilities, achieving 550 nits of peak brightness. This allows for enjoyment of HDR effects, which is clearly visible in scenes such as the first from the movie Life of Pi or the last frame from The Meg. However, the limited number of dimming zones causes some problems. 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. The dimming algorithm aims for deep blacks, but at the cost of brightness – which in these moments leads to a decrease in brightness by as much as half. In these more challenging scenes with small elements, it is hard to find any praise, and the HDR effect resembles rather SDR. Nonetheless, the coverage of the color palette deserves commendation, which, like in the version without the PRO suffix, is at a very good level.

DU8002 offers a Filmmaker mode, which is supposed to provide authentic image reproduction in line with the creators' intentions. Unfortunately, despite the promising name, the results are far from ideal. The white balance in this mode shows significant drops in blue color, leading to a noticeable yellowing of the image, which can be seen, for example, in our comparison photo. Colour Checker tests confirm these errors. As for brightness, the gamma characteristic is too low compared to the reference line of 2.4, resulting in excessive screen brightness. A similar problem occurs with 4K content – the EOTF responsible for brightness in 4K material shows significant increases above the reference line, leading to excessively bright small light elements. As a result, the Filmmaker mode in DU8002 does not meet expectations and instead of offering high quality, presents an image full of tonal and color inaccuracies.

Each of our TV tests is conducted in movie mode, which usually offers the best color reproduction. Nevertheless, even this mode is not free from problems, as we noted with 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 excessively enhance the blue color. As a result, the image can appear artificially sharp, which proves to be uncomfortable for the eye over a longer period. The brightness characteristic also leaves much to be desired. The Gamma chart indicates serious difficulties with excessive brightening, causing the overall presentation to look washed out. Additionally, the EOTF curve reveals significant issues with the reproduction of very small elements - they are excessively dimmed, as we detailed in the paragraph regarding HDR effects.

Samsung is one of those companies that offers advanced tools for improving image quality in its televisions, including a 20-point white balance adjustment. Even with the budget model DU8002, with the right adjustments, surprisingly good results can be achieved. The white balance, especially for HD content, performs really well - tests on the Colour Checker palette confirm accuracy at the level of 2–1.5, which demonstrates the significant capabilities of this television in color reproduction. In 4K content, although not as perfect as in lower quality material, the overall picture looks much better.

The gamma brightness has also been heavily adjusted, ensuring that the image is not overly brightened and looks more natural. What about the EOTF curve? At first glance, it seems fine, but upon closer inspection, especially in film tests, it becomes apparent that the television struggles due to its low contrast panel. The EOTF drops below the reference line. Nevertheless, the DU8002 is an example of a budget model where investing in calibration is worthwhile. Although structural flaws, such as the type of backlighting, cannot be completely eliminated, color accuracy is surprisingly good, especially considering its price.

After calibrating the TCL 655 PRO television, a noticeable improvement in white balance can be observed, having completely eliminated the tendency for the screen to have an excessive pink hue, which was previously visible in factory mode. The image has taken on more natural tones, especially in white and bright elements, positively affecting the overall perception of the picture. As for brightness characteristics, the Gamma chart has also improved – the screen is no longer excessively bright, which previously made the image look washed out. Nevertheless, there are still some issues with the EOTF curve that are difficult to eliminate due to the design of the television and its limited number of dimming zones. These limitations prevent achieving ideal results in this regard. However, despite this minor flaw, the overall effect after calibration is truly outstanding, providing high image quality and very good color reproduction.

Smoothing tonal transitions on the DU8002 television leaves mixed feelings. Although the menu offers an option for smoothing tonal transitions, in practice it yields no results and can even generate unwanted side effects.

Nevertheless, the television handles upscaling, or digital image processing, excellently. The test chart featuring a model looked really good – the image is not overly jagged, and the overall presentation is decent and pleasing to the eye. This is definitely good news for those planning to watch traditional television on this model.

The TCL 655 PRO television handles tonal transitions in lower-quality materials quite well. The "Gradual Smoothing" feature at a low setting effectively smooths out tonal transitions; however, this comes at the cost of losing some important details, such as the texture of objects. A positive aspect is that it does not negatively affect film grain, which helps maintain the natural look of the image.

In the context of digital processing, the television adds artificial sharpness. This may appeal to users who prefer a more vivid image. However, those who favor a softer, subtler look may find this to be a drawback. Additionally, a downside is the image cropping due to overscan, which limits the field of view and trims the edges of the frame. This can be problematic in certain scenes - e.g., news tickers.

DU8002 with a 60 Hz panel is a television that performs better for watching movies than for intense gaming. The motion smoothing feature acts as a fluidizer, smoothing out motion and giving scenes a more fluid appearance, which is useful for movie screenings. In the context of gaming, this model will rather be suitable only for occasional entertainment.

The TCL C655 PRO TV is equipped with a 4K panel with a refresh rate of 60 Hz, making it ideal for watching movies. Additionally, the "Flicker Reduction" feature allows users to adjust the fluidity of the image, giving them the choice between smoother motion or a cinematic, choppy effect. Moreover, the TV handles lower resolution content well, such as Full HD and 2K, offering a refresh rate of 120 Hz, which will certainly appeal to gamers who can enjoy smoother images, albeit at the cost of lower resolution.

DU8002 is a television that will mainly serve as equipment for casual gamers. The 60 Hz panel does not provide the highest motion fluidity, so in dynamic games there may be a lack of that extra smoothness of the image. On the positive side, it features ALLM and HGiG functions, which automatically adjust image settings for HDR games, enhancing the gaming experience. Unfortunately, the television is equipped only with HDMI 2.0 ports, so we have to forget about more advanced features like VRR or support for 4K at 120 Hz. When choosing this equipment, we will have to make do if we expect a full set of gaming features.

The TCL C655 PRO television offers an almost perfect set of features for gamers, supporting all key technologies that significantly improve the gaming experience. The ALLM feature automatically switches the television to low latency mode, resulting in better responsiveness and minimized signal delays – particularly important in dynamic titles. VRR synchronizes the screen refresh rate with the number of frames generated by the console, eliminating screen tearing and thus guaranteeing smoother gameplay.

Support for Dolby Vision in game mode allows for more detailed color and contrast reproduction in games that support this format, while the Game Bar provides quick access to important settings such as response time or latency level. Unfortunately, this model does not support 4K resolution at 120 Hz, which may disappoint the most demanding gamers. However, for those who can forgo 4K, support for Full HD and 2K at 120 Hz offers exceptionally smooth visuals, making it an attractive alternative for enthusiasts of higher refresh rates.
