Samsung Neo QLED QN90D / QN92D vs TCL C655 / C69B 98'

During synthetic tests, the Samsung QN92D demonstrated remarkable brightness capabilities, reaching an impressive 2000 nits—on par with top models in the market. This level of brightness puts it at the forefront for displaying HDR content, where high brightness is essential. But how does it fare in real movie scenes? Under favourable conditions, such as the light-drenched opening and closing scenes of Life of Pi, the QN92D nearly replicates its lab results, delivering striking brightness levels. However, performance changes in scenes featuring small, bright objects against dark backgrounds, such as the fourth scene in Sicario. Here, brightness levels drop significantly, with maximum values capping at around 600 nits.

As with contrast, these limitations are due to the aggressive local dimming algorithm, which aims to reduce the "halo" effect around bright objects in dark scenes but often sacrifices overall brightness. Consequently, while the TV excels in scenes with abundant light, it faces challenges maintaining brightness with smaller, bright elements on dark backgrounds.

The quality of the HDR effect on TCL C655 / C69B looks quite promising. The average value in test patterns is about 450 nits, which already allows you to feel the brilliance of light effects and better image dynamics. However, as previously mentioned, this effect can be somewhat muted by slight differences in bright and dark colors, resulting from the lack of local dimming technology. However, the coverage of the DCI-P3 color palette at 94% deserves high praise, and this is possible due to the use of a quantum dot (QLED) matrix. As a result, colors are vibrant and well-reproduced when watching HDR content.

The best mode for colour reproduction on the Samsung QN92D is Filmmaker mode. Although it generally offers good colour quality, it is not without significant issues. Starting with HD/SDR image quality, the main challenge is white balance. The graphs reveal considerable instability, with a dominant red tint that makes the image appear too warm. This imbalance causes shades to shift unnaturally towards warmer tones, potentially affecting the perception of natural colours. Additionally, while contrast, as indicated by the gamma chart, is not the worst, it still falls short of the ideal, impacting overall image quality, especially in darker scenes.

This issue continues with 4K content, such as high-quality series or films. Here too, white balance proves problematic, with noticeable deficiencies in both blue and red, leading to tonal shifts. Tests using the Colour Checker tool confirm these issues, showing a tendency for colours to skew toward yellow hues, further distorting the natural look of the image. While Filmmaker mode remains one of the best options for cinematic content, it could still benefit from improvements, particularly in colour accuracy and white balance.

The TCL C655 / C69B TV offers a movie mode that has been tested for color reproduction quality. Although this mode is called movie mode, it unfortunately has quite a few flaws that a director would certainly not want to see when recording their work. Starting with image analysis, it's worth looking at the white balance – both in HD and 4K HDR content, the white balance has significant errors. In both cases, the red color dominates, which makes the colors too warm, and the overall image takes on a pink or yellow tint. The Colour Checker test confirms these errors – the color samples shift to the wrong shades, affecting overall color fidelity. A lesser issue is the brightness characteristics. However, it is also not without flaws. The gamma chart shows a strong spike at the beginning, which can make the image excessively bright, and the EOTF curve responsible for brightness in 4K HDR content also has significant fluctuations – it is evident that the TV tries to maintain appropriate brightness, but it does not always succeed effectively.

After calibration, the Filmmaker mode on the Samsung QN92D shows significant improvement, particularly with SDR content. The white balance has been greatly enhanced — previous colour shifts and red dominance have been corrected, resulting in more natural colour reproduction. Although the gamma curve didn’t require major adjustments, its stabilisation has positively impacted overall picture quality.

In high-quality materials, the white balance has also improved. However, contrast remains an area to watch. The EOTF curve initially appears accurate, but closer inspection reveals that the television struggles to maintain consistent contrast in film content, indicating further room for improvement. Despite these areas, one advantage is the TV’s colour saturation. Skin tones are rendered well, and while some colours may be slightly oversaturated, the overall effect is rich and vibrant.

Despite minor contrast limitations, the calibrated Filmmaker mode on the Samsung QN92D delivers excellent picture quality, with natural colours, making it a strong choice for movie watching.

After calibrating the movie mode of the television TCL C655 / C69B , the white balance has been adjusted, and the colors appear as they should – which is confirmed by only slight deviations in the Colour Checker test. The gamma is really good, which means the television shouldn’t have issues with brightness in low-resolution materials. Unfortunately, a similar EOTF characteristic is still noticeable, which is a natural phenomenon 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 that cannot be bypassed, we recommend adjustments in the settings because the overall color presentation is really very good.

Let's examine how the Samsung QN92D television manages tonal transitions in low-quality materials. The noise reduction function is highly effective, enhancing the fluidity of tonal transitions even under challenging conditions. However, it’s worth noting that, as with other Samsung televisions, this feature can occasionally remove desirable elements, such as film grain, which may affect image authenticity. 

In terms of digital processing, the Samsung QN92D also performs impressively. During testing, the image appeared natural and well-balanced, with details like background branches precisely reproduced, underscoring the television’s ability to enhance the quality of low-resolution materials.

The TCL C655 / C69B TV handles tonal transitions well in lower-quality content. The "Gradual Smoothing" feature at its lowest setting effectively eliminates visible banding, but it also results in a loss of detail, such as in the texture of objects. A plus is that it does not interfere with film grain, allowing the image to maintain a natural look.

In terms of digital processing, the TV adds a considerable amount of artificial sharpness, which may appeal to those who prefer a vivid image. For those who prefer a more subtle representation of details, this could be a drawback. Another downside is the rather aggressive overscan – the image is cropped, which leads to the loss of parts at the edges and limits the field of view.

The Samsung QN92D TV features a 144 Hz panel, however, when using the motion smoother, the maximum refresh rate adjusts to 120 Hz. This setup ensures excellent picture quality for both gamers and sports enthusiasts. Additionally, the TV offers a range of image enhancement options, such as the "blur and judder reduction" feature, which lets users fine-tune smoothness on a 10-point scale. Blur reduction sharpens fast-moving objects, while judder reduction smooths out motion, eliminating the "stutter" effect. With these advanced settings, the Samsung QN92D provides optimal visual experiences for dynamic scenes and intense gameplay alike.

The TV performs impressively in terms of motion blur, with minimal issues. The only minor drawback is a slight overshoot effect noticeable on dark backgrounds in our "Ufoludkiem" test. Nonetheless, with its advanced smoothness settings, the Samsung QN92D delivers outstanding performance for both fast-paced scenes and immersive gaming sessions.

Unlike the smaller versions, the 98” model stands out with significantly better motion fluidity. Instead of the standard 60 Hz, this colossal screen is equipped with a full-fledged 144 Hz matrix, which opens up completely new possibilities – both for gamers and movie enthusiasts. With full motion smoothing, the TV provides incredible image fluidity, eliminating motion blur and improving the viewing comfort of dynamic scenes. It is worth emphasizing that this technology operates across the full refresh rate range, meaning there is no need to compromise between fluidity and quality. Additionally, the "Flicker Reduction" feature allows you to adjust the fluidity to your own preferences – you can opt for a more cinematic effect with visible frame drops or a maximally smooth image.

The Samsung QN92/QN90 TV is an outstanding choice for avid gamers and is highly recommended. This model provides virtually every gaming feature currently available, enhancing the excitement of gameplay. A standout feature is the 120 Hz panel, delivering impressive motion smoothness, which is especially beneficial during action-packed games.

Additionally, VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode) optimise refresh rates and automatically activate gaming mode, further elevating the gaming experience. An additional bonus is the Xbox app, enabling users to play directly on the TV without needing a console—an exclusive feature in Samsung TVs, adding to their appeal in the gaming world.

Samsung’s Auto Motion Plus Game feature deserves particular praise. This motion smoother is highly effective in gaming, making lower frame rates appear smoother—30 frames per second can look like 45, and 60 Hz can resemble 90 Hz. Crucially, it achieves this without introducing noticeable input lag (keeping it below 25 ms), so gameplay remains highly responsive, unlike many other motion-smoothing options on the market. As a result, players can enjoy a smoother visual experience without sacrificing responsiveness.

The 98-inch TCL C655 / C69B is excellently equipped for gamers. Full-fledged HDMI 2.1 ports and a 144 Hz panel allow you to enjoy games in 4K resolution at 120 Hz, providing smoothness and responsiveness that will impress even the most demanding.
