TCL A300W NXTVision vs Samsung QN90F / QN92F

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 Samsung QN90F can truly shine in brightness. In our measurements, it achieved over 2200 nits, which directly translates to the viewing experience. Practically, this means that when a very bright scene appears in a movie – for example, the sunrise in The Meg – the screen looks as if natural light is actually shining on us. This isn’t just a number from a chart, but a real sense of image intensity! However, the TV cannot always deliver that full power. With smaller details, such as headlights or lamps, the brightness drops to 500–700 nits. This is a conscious decision by the algorithms – this way, the contrast between large and small elements is better controlled, and the image does not lose balance. Importantly, this is still a huge improvement compared to last year's QN90D, where similar details were almost invisible, shining at just 200 nits. Here, the HDR effect is much more consistent and credible. The only downside is the colors. The coverage of the DCI-P3 palette stopped at 91%, which can be considered a rather average result in this price range.

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.

We tested color reproduction in the QN90F in Filmmaker mode, and as usual with Samsung TVs, this mode proves to be the best starting point right out of the box. However, this does not mean that the image is free from flaws. The white balance in SDR and HDR content was surprisingly good – the colors didn’t shift in any direction, and even in the factory setting, it looked solid. However, a problem arose with the gamma and EOTF curves, which are responsible for how the TV manages brightness. Here, the QN90F significantly brightened the entire image, causing black levels and colors to lose their intensity, and the overall effect resembled a milky filter being applied. Fortunately, Samsung, unlike many competitors in the miniLED world, provides users with a lot of tools to control the settings that we don’t find with other manufacturers, such as Chinese brands. Therefore, we decided to check if it was possible to extract the full potential of the QN90F because we know that such a high series can deliver much more.

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.

After our adjustment of the settings, the QN90F showed what it is really capable of – and it must be admitted that it has one of the best images we have seen on a miniLED screen this year. As we mentioned earlier, the white balance was not a major issue even in its factory version, but only after the gamma calibration were we able to get close to nearly reference values. The same is true for HDR content, where the EOTF curve after correction presents mature and consistent results. Indeed, in some films, it can be noticed that the smallest elements of the image are slightly brightened, and with a limited number of dimming zones, there is still a risk of the halo effect. It should be remembered, however, that such phenomena are characteristic of all miniLED televisions, and it's hard to expect miracles even from the QN90F. The most important thing is that after calibration, the television shows an image that, in terms of conveying the director's vision, confidently competes even with many OLED screens available on the market.

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.

QN90F handles upscaling very well. Materials in lower resolution, even SD, are boosted to a clear and sharp image, showcasing plenty of details in the background. This is a significant advantage because the television makes older content or everyday TV look much better than on most budget screens. However, the issue of overscan remains, which is the trimming of the edges of the screen that cannot be turned off in Samsungs. This can cause some subtitles on the screen to disappear or a relative's face from a wedding on a VHS tape to be slightly cropped. 😉

The digital image processing also works well. In the menu, we find a feature called "noise reduction," which can smooth out tonal transitions and improve the reception of lower-quality materials, such as from YouTube. In medium setting, the effect is the most beneficial – it does not heavily interfere with details while eliminating the "stair-stepping" problem in colors. However, it is important to remember that the feature can be quite aggressive and can also remove natural grain in older films, so it's best to use it in moderation.

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 QN90F is equipped with a panel that has a maximum refresh rate of 165 Hz, and while primarily PC gamers will appreciate this advantage, it is still worth highlighting. In movies or sports broadcasts, we are limited to the classic 120 Hz, but this is not a cause for concern. In practice, the additional motion smoother plays a more significant role here. With the "Motion Clarity" setting, we can adjust the image to our own preferences. The blur reduction option is responsible for smoothness and trailing in sports. Meanwhile, the "judder reduction" function improves motion smoothness in productions recorded at 24 frames, such as movies and series. If we set it high, the film looks smoother and more fluid than it was actually filmed. Lower values, on the other hand, maintain its cinematic "rawness" with the visible film frame.

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.

QN90F has nearly everything to become the perfect television for gamers. Things like four HDMI ports, VRR, ALLM, and refresh rates reaching up to 165 Hz are probably well-known. It deserves high praise for the Game Motion Plus mode, which is a proprietary motion smoothing technology for games. Thanks to this, it can add a few “artificial” frames and make the image generated from the console look smoother than it should. This is a very unique solution in the world of televisions – competitive systems usually do not offer this – which is why Samsung has had a strong bargaining chip among gamers for years, even despite the lack of support for the still niche Dolby Vision in games.

[UPDATE] We have updated our tests of Samsung televisions from the 2025 model year due to the release of software version 1131, which restored the crucial gaming feature HGiG.

So why are we writing about a “nearly” perfect screen? Unfortunately, similar to recent Samsung models, we noticed an issue with the lack of the HGiG feature. This solution allows the television to leave control over tone mapping to the console, so that games look exactly as the creators intended. Worse still, this feature was previously present, and it disappeared after software updates. Instead of minor tweaks, we received a step back. It’s a shame because if it weren't for this absence, the QN90F could truly be the perfect choice for gamers in the miniLED category.
