Samsung DU8002 (IPS) vs TCL C655 / C69B (55"-85")

The HDR effect on the DU8002 television leaves much to be desired. A brightness level of 300 nits is unable to provide a true high dynamic range experience, making the content viewed resemble more standard SDR than impressive HDR. Scenes that should dazzle with brilliance and detail appear muted and lack depth. Nevertheless, the television deserves praise for its high coverage of the DCI-P3 colour palette at 92%. This allows for vibrant and saturated colours, which may please viewers who prefer rich tones, even if the HDR effect does not fully meet expectations.

Overall, the quality of the HDR effect in TCL C655 / C69B looks quite promising. The average value in the test patterns is around 450 nits, which already allows you to feel the light effects and better image dynamics. However, as mentioned earlier, this effect may be somewhat subdued by slight differences in bright and dark shades, resulting from the lack of local dimming technology. However, the DCI-P3 colour gamut coverage of 94% deserves high praise, and this is possible due to the use of a quantum dot (QLED) panel. This makes the colours vibrant and well-reproduced when watching HDR content.

DU8002 offers a Filmmaker mode, which is supposed to provide authentic image reproduction in line with the creators' intentions. Unfortunately, despite its promising name, the effects are far from ideal. The white balance in this mode shows significant drops in blue colour, leading to a noticeable yellowing of the image, as seen in our comparison photo. Colour Checker tests confirm these errors. Regarding 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 materials shows significant increases above the reference line, leading to overly bright small light elements. As a result, the Filmmaker mode in DU8002 does not meet expectations and instead of providing high quality, presents an image full of tonal and colour inaccuracies.

The TCL C655 / C69B television offers a film mode that has been tested for colour reproduction quality. Although this mode is called film mode, it unfortunately has quite a few errors that the director would certainly not want to see when filming their work. Starting with image analysis, it's worth looking at the white balance – both in HD content and 4K HDR, the white balance has significant issues. In both cases, the red colour dominates, resulting in colours that are too warm, with an overall pink or yellow tint. This can be seen in the image below from the film "Star Wars." The Colour Checker test confirms these errors – the colour samples stray into incorrect shades, affecting the overall colour fidelity. The brightness characteristics are a lesser issue. However, they are not without flaws either. The gamma chart shows a strong spike at the beginning, which can cause the image to be overly bright, and the EOTF curve responsible for brightness in 4K HDR content also has significant fluctuations – it's evident how the television tries to maintain appropriate brightness, but it doesn't always succeed effectively.

Samsung is one of those companies that offers advanced tools to enhance picture quality in its televisions, including a 20-point white balance adjustment. Even in the budget model DU8002, after proper 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 levels of 2–1.5, which indicates the significant capabilities of this television in colour 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 significantly adjusted, meaning the image is not overly brightened and appears more natural. What about the EOTF curve? At first glance, it seems fine, but upon closer inspection, especially in film tests, it's clear that the television struggles due to its low-contrast panel. And the EOTF drops below the reference line. Nevertheless, the DU8002 is an example of a budget model where investing in calibration is worthwhile. Although construction flaws, such as the type of backlighting, cannot be completely eliminated, colour accuracy is surprisingly good, especially considering its price.

After calibrating the movie mode of the television TCL C655 / C69B , the white balance has been adjusted, and the colours look as they should – which is confirmed by only slight deviations in the Colour Checker test. The gamma is really good, which ensures that the television shouldn't have any issues with brightness in low-resolution material. Unfortunately, a similar EOTF characteristic is still noticeable, which is a natural occurrence in televisions that do not have local dimming – they simply struggle to "shine" brighter in a given part of the screen. Despite this design limitation, which cannot be bypassed, we recommend making adjustments in the settings, as the overall colour presentation looks really very good.

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

Nonetheless, the television handles upscaling, or digital image processing, exceptionally well. The test pattern with the model looked really good – the image isn't 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.

Television TCL C655 / C69B handles tonal transitions in low-quality materials fairly well. The "Gradual Smoothing" feature on low settings effectively smooths out tonal transitions, but it also blurs important details, such as the texture of objects. A positive aspect is that it does not negatively affect film grain, which helps to maintain the natural look of the image. In terms of digital processing, the television adds artificial sharpness, which some users who prefer a sharper image might appreciate. However, for those who prefer a softer look, this may be a drawback. Another downside is that the image has been significantly cropped due to the so-called overscan, which reduces the field of view and cuts off the edges of the image.

The 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 fluid enhancer, smoothing out movement and giving scenes a more fluid appearance, which is useful for movie sessions. In the context of gaming, this model is likely only suitable for occasional entertainment.

The television C655 / C69B is equipped with a 4K@60 Hz panel, which means it's best suited for watching movies and less dynamic content. It also features a "Flicker Reduction" function, allowing users to adjust the smoothness of the image – they can choose whether they prefer smoother motion or a more cinematic, frame-like effect. The television can also adapt to lower resolutions, such as Full HD and 2K at 120 Hz, which will surely please gamers by offering a smoother image at the cost of resolution. It’s worth noting that this feature is available in sizes starting from 55"+. Additionally, the largest variant, 98", is equipped with a 144Hz panel with full motion smoothing.

DU8002 is a television that is mainly suited for casual gamers. The 60 Hz panel won't provide the highest motion fluidity, so in dynamic games, you might miss that extra smoothness of the image. On the plus side, it has ALLM and HGiG functions, which automatically adjust the picture settings for HDR games, enhancing the gaming experience. Unfortunately, the TV only comes with HDMI 2.0 ports, so we have to forget about more advanced features like VRR or support for 4K at 120 Hz. Choosing this equipment means we will have to make do without a full set of gaming features.

The TCL C655 / C69B TV offers an almost perfect set of features for gamers, supporting all the key technologies. It has an ALLM feature that automatically switches the TV to low latency mode, significantly improving responsiveness and minimising signal lag, which is especially important during dynamic gameplay. The VRR feature allows synchronisation of the screen refresh rate with the number of frames generated by the console, eliminating screen tearing and providing smoother gameplay.

The TV also supports Dolby Vision in gaming mode, ensuring better colour and contrast reproduction in games that support this format, and the Game Bar enables quick access to gameplay-related settings, such as response time, latency level, and other parameters. Unfortunately, the C655 / C69B does not support 4K resolution at 120 Hz (the 98" variant is the exception), which may be disappointing for more demanding gamers seeking the ultimate smoothness in high-resolution games. However, if we can forgo 4K, the TV offers support for Full HD and 2K at 120 Hz, providing a smoother image and serving as a great alternative for those who prefer higher refresh rates at the expense of resolution.
