Samsung Neo QLED QN90D / QN92D vs TCL A300W NXTVision

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.

When it comes to brightness, the TCL A300W is definitely the darkest TV among all frame-style models, such as Samsung The Frame or Hisense CanvasTV – and unfortunately, this is immediately noticeable. In our measurements, the peak luminance reached only about 400 nits, and on test film screens, this value dropped to 350 nits. This is definitely too little to feel the true "magic" of bright HDR effects. As a consolation – the TV is equipped with a PFS LED coating (which is something like QLED), which provides very good coverage of a wide color palette, both DCI-P3 and BT.2020. Additionally, there is full support for all popular HDR formats – HDR10, HDR10+, HLG, and Dolby Vision – which somewhat compensates for the shortcomings in brightness and helps improve the overall perception of materials in this quality.

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.

TCL A300 offers several picture modes, but without a doubt, the movie mode performs the best. Unfortunately, although it is the best choice among the available options, it is not free from errors. Both in HD and HDR content, the image has a noticeably too warm tint – leaning slightly towards pink, which is particularly noticeable in snowy scenes. Instead of pure white, we get a pinkish hue that spoils the natural perception of colors.

The brightness management doesn't perform well either. For older HD materials, the image often seems too dark – as confirmed by the inflated gamma value. Conversely, with HDR content, the effect is reversed – the image is overly brightened, which we observed in scenes from the movie Pan. This lack of consistency also affects color reproduction accuracy – a test with the ColorChecker showed that many samples deviate significantly from the reference values.

Fortunately, TCL allows manual adjustment of the settings, so we decided to check how the television would perform after our professional calibration. The effects of this correction are described below.

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 our professional calibration, the TCL A300 literally got a new lease on life. The image is no longer too warm, and the colors finally look the way they should – which was confirmed by the ColorChecker test, where the color samples finally started hitting their marks, at least to some reasonable degree. It was also possible to partially correct the brightness management – the image is now more balanced and less "wobbly" between different types of content. Of course, certain limitations cannot be overcome – a slightly noticeable blooming effect still occurs, but that's a characteristic of the technology, not something that can be eliminated even after professional settings.

Generally: after calibration, the A300 looks significantly better and gains a completely new quality.

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.

TCL A300 handles tonal transitions in high-quality films very well, but the question arises – how does it perform with weaker materials? The television is equipped with a tonal transition smoothing feature, but its effectiveness can be described in one word: "random." In one scene it may work and improve the gradation, and when turned off… the effect remains the same. There is a lack of consistency and predictability.

Image scaling is also not one of the A300's strong suits. In the test pattern, the main character actually looked better than on the raw signal, but with thin lines – like fonts or background details – there was noticeable jaggedness and aliasing. On the plus side, the television does not cut off the image and has no issues with overscan, but the overall quality of scaling is rather average.

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.

The TCL A300 is equipped with a 144 Hz panel, which should immediately satisfy practically everyone – both gamers and sports fans. The motion is smooth, and the picture is clear even in fast scenes. Additionally, the television offers a motion enhancement feature called "Motion," where we can find two sliders on a 10-point scale. These allow for adjusting the effect to personal preferences – from a classic, cinematic look with visible frames to a very smooth (though already unnatural) image reminiscent of a soap opera effect. Thanks to this, everyone can find a setting that suits them.

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. The TV also boasts low input lag, ensuring quick responses to player commands. 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.

TCL A300 is a television designed not only to transport us to a digital art museum but also to a full-fledged gaming world. It offers practically everything you would expect from gear for gamers: two HDMI 2.1 ports with full bandwidth, 144 Hz refresh rate, VRR support, and ALLM.

The correct implementation of the HGIG mode is also a plus – something that competing Hisense sometimes struggles with. The television easily handles lower resolutions (e.g., Full HD) while maintaining high refresh rates, which will be appreciated by owners of older consoles or PCs.

In addition, there’s an attractive and clear GameBar that facilitates quick access to settings for gamers. The A300 is truly well-prepared for gaming at the highest level – it's just a shame that issues with motion blur slightly tarnish its overall image as a gaming device.
