Samsung Neo QLED QN95D vs TCL A400 PRO

Samsung QN95D handles HDR exceptionally well, achieving a peak brightness of around 2000 nits. In the tested movie scenes, where the screen is fully lit, the television provides intense and realistic representation of HDR content, significantly enhancing the visual experience. Nevertheless, similar to contrast, the dimming algorithm may sometimes show limitations. Despite the considerable number of Mini LED zones, the television does not surprise the user with incredible brightness. For instance, in scenes from the film "Life of Pi," where a bright moon appears against a dark background, and in excerpts from "Sicario 2," where a strong light effect occurs on a dark background, the television displays very poor results. At such moments, the television attempts to reduce the halo effect by darkening the image to a level reminiscent of SDR quality. As a result, blacks appear deep and uniform, but this comes at the cost of losing some detail in bright areas. It is a compromise aimed at maintaining the best possible quality of black, although it simultaneously causes the image to lose a bit of its dynamism. Despite certain flaws in the operation of the local dimming algorithm, this television deserves praise for its wide coverage of the DCI-P3 colour gamut. This is made possible by the use of a quantum dot coating, also known as QLED technology, which allows for vibrant and rich colours.

The TCL A400 Pro is a moderately bright TV. Its peak brightness reaches around 600 nits. That level already allows for a real HDR effect, and in many films it does produce a noticeably more attractive picture than in SDR. However, it is not a level that overwhelms with sheer brightness. The A400 Pro therefore isn’t one of those TVs that ‘attack’ the viewer with a powerful flash in every eye-catching scene. The biggest limitation is seen with small bright elements on a dark background. Because of fairly aggressive local dimming control, the TV can significantly reduce their brightness, in extreme cases even to around 100 nits. This means that small lights, sparks, stars or individual highlights can be much less visible than they should be. It’s worth adding, however, that this isn’t without reason. The A400 Pro does this to maintain as deep a black level as possible and to limit the halo effect around bright objects. So it’s an intentional compromise: the TV more often opts for deeper blacks rather than maximally bright, point-like highlights. On one hand this can be understood, especially given the limited number of dimming zones, but on the other you should be aware that the HDR effect won’t always be as strong as the peak brightness alone might suggest.

On the plus side, the colours are a strength. The PFS LED filter used here, marketed by the manufacturer as QLED, allows for suitably saturated colours. Coverage of the DCI-P3 gamut measured around 94%, and BT.2020 around 74%, which is a solid result for this class.

In the category of factory colour reproduction, the television Samsung QN95D was tested in Filmmaker mode, which offers the best settings from the manufacturer. Nevertheless, it is not entirely free from flaws. In the case of HD content, there is a noticeable colour deviation, particularly in white balance, where the red colour clearly dominates the graph. The situation improves with 4K HDR content; however, there are still significant drops in blue colour reproduction. These effects can be observed in a scene from the film "Star Wars," where the protagonist is depicted in overly warm tones.

As for contrast, we can observe an initial large jump on the gamma graph, indicating that the television effectively highlights the brighter parts of the image. However, at the end of the graph, we notice a distinct drop, which may mean that in darker tones, details can be lost. Such a shape of the gamma curve can affect the way users perceive dark scenes, where some details may become too blurred or too dark, causing the image to lose clarity. It is also worth noting the curve responsible for brightness (EOTF), which is quite correct, except for the initial drop.

Although Samsung QN95D boasts impressive parameters and advanced technologies to deserve the title of one of the best televisions on the market, it requires certain adjustments in colour reproduction and contrast to fully utilise its potential.

As standard, we performed colour measurements in the best‑tuned Filmmaker Mode, the mode that is designed to be closest to the creators' intentions. The A400 Pro of course also offers other picture modes, but in practice these come with considerably larger colour errors and interfere more with the character of the image. Therefore we will not deal with them in detail in this part of the test. So how does the out‑of‑the‑box colour reproduction fare? In short: really very good. Actually, looking at our measurement results, downright excellent. Both the white balance and the luminance response were set surprisingly precisely. The errors were so small that during measurements we genuinely rubbed our eyes in amazement. Such good factory settings do not happen often, even in TVs operating in Filmmaker Mode. All the more credit is due to TCL, because the A400 Pro right out of the box can deliver an image very close to how the source material should look. The results were so good that one could easily think someone had already given this unit extra attention and tried to calibrate it.

Our nitpicking really comes down to just one thing. In SDR content the image was slightly brighter than the dark‑room reference intends, because the factory gamma was set closer to 2.3 than to 2.4. This is not a large error and most viewers will probably not even notice it.

It should, however, be noted that we are talking about our specific test sample. With factory colours there can always be some variation between units, production batches or screen sizes. We do not assume, therefore, that every A400 Pro will look identical straight out of the box.

After calibration, the picture on the Samsung QN95D television achieves truly impressive results. The white balance is perfectly aligned, and error readings rarely exceed 2, which means that colours are displayed very accurately. Most samples from the Color Checker test fall within an acceptable error range, confirming that the television reproduces hues excellently. The contrast has also improved significantly, and the gamma curve is more stable, resulting in better visibility of details in both dark and bright scenes. However, it is worth noting the EOTF (Electro-Optical Transfer Function) curve, which shows some discrepancies in film tests. Although the television performs well in most scenes, details in the blacks can still be lost in more extreme cases – this is due to an aggressive dimming algorithm.

Nevertheless, these minor imperfections do not detract from the overall picture quality. After calibration, the Samsung QN95D impresses with its visual quality, offering an exceptional experience that will certainly satisfy anyone looking for a top-tier television.

Despite its superb factory calibration, we couldn't resist checking how the TCL A400 Pro would respond to professional calibration. Since the starting point was so good, we were all the more curious whether there was anything more to be had from the TV. And here we must boast: we managed to reduce our unit's colour errors to absurdly low levels. Measurements below a value of 1 are not something you see every day, even in very good TVs. Such results are more commonly associated with professional reference monitors than with a lifestyle TV for the living room. In terms of white balance and colour reproduction the A400 Pro therefore simply performed exceptionally well after calibration. The only gripe we have after closer analysis relates to the luminance behaviour. The TV adjusts luminance depending on the content being displayed and quite often the picture is slightly darker than the reference calls for. This is most likely due to the way the Mini-LED backlight and local dimming algorithms operate in this model. However, this does not spoil the overall impression, because in terms of colour accuracy alone the calibrated A400 Pro showed a level that was really hard to expect.

The Samsung QN95D television handles tonal transitions even in lower quality materials, thanks to the noise reduction feature employed, which functions like a gentle gradation. This feature is extremely effective, smoothing out the image and eliminating unwanted noise while significantly improving the quality of the displayed material. However, as is often the case, too much effectiveness can lead to unintended side effects. In some materials, this feature may also blur elements that should remain sharp, such as film grain.

Despite this, the television performs well in the context of image scaling, eliminating larger jagged edges. In a scene where branches are visible, they are not excessively artificially sharpened, allowing for a natural appearance, and the model does not have an artificial outline. Overall, this means that even in more challenging conditions, the film material presents itself satisfactorily on the Samsung QN95D. The only downside when watching HD/SD content (such as regular terrestrial television) is the fact that we have a slightly cropped image – this is caused by the so-called overscan, which cannot be turned off.

Digital image processing is, unfortunately, one of the weaker points of the TCL A400 Pro. That does not mean the TV performs badly, but it is hard to call it anything clearly above average. The upscaling itself is adequate: edges are smoothed fairly well, the picture does not look overly sharp or "pixelated", and lower-quality content can be watched without much discomfort. At the same time, the overall image is slightly soft and lacks the precision offered by the best image processors in more expensive TVs.

Much worse, however, is how it handles tonal transitions caused by strong signal compression. TCL has equipped the A400 Pro with a "Gradual Smoothing" feature that, in theory, should limit visible colour banding and artifacts in lower-quality material. In practice, though, its effectiveness is very limited. It does not improve tonal transitions in any noticeable way, and at higher settings it can also smooth out image details, giving the picture an artificial, slightly blurred character. For that reason, we think it is best to leave this feature off. The A400 Pro copes decently with basic image scaling, but if you often watch heavily compressed content with noticeable posterisation, this model will not be among the best choices.

The panel in Samsung QN95 performs very well in terms of motion blur and smoothness of movement. With a refresh rate of 120 Hz and features for reducing blur and judder, the picture settings can be customised to personal preferences, whether for watching films or for dynamic sports broadcasts. The user has the option to adjust the smoothness of the image on a 10-point scale – from a more frame-like appearance reminiscent of traditional film to a smooth, almost theatrical effect, which works particularly well for sports transmissions.

The TCL A400 Pro is equipped with a 144 Hz panel, but in practice we are most interested in its behaviour at 120 Hz. That is the frequency most consoles are limited to today, as well as many sports broadcasts and high-frame-rate content. At that rate the TV performs quite well. The sharpness of moving objects is really good, especially after properly configuring the motion smoothing. The "Motion Clarity" function is responsible for improving smoothness. Its settings include two sliders that let you tailor how the motion smoothing operates to your preferences, separately for lower and higher frame-rate material. This makes it possible to achieve both a more cinematic look and a noticeably smoother picture. Those who do not want to fiddle with manual configuration can use presets such as low, medium, high, cinema or nature.

Samsung QN95D offers quite a few features that gamers will appreciate. First and foremost, the television supports variable refresh rate (VRR), which allows for smoother gameplay, eliminating issues with tearing, especially during dynamic scenes. We also find the auto low latency mode (ALLM) feature, which automatically switches the television to low latency mode when it detects a connected console or computer, ensuring more responsive controls.

Furthermore, the QN95D Samsung has a game mode that reduces input lag to a very low level, which is crucial in games where reflexes play an important role. With a high refresh rate of 120 Hz, the picture is exceptionally smooth, significantly enhancing the experience of fast-paced action games and sports productions. The television also supports G-Sync and FreeSync technologies, which further enhance gameplay smoothness and improve user comfort. An interesting addition is the 'Game Bar' – a special menu that provides quick access to all game-related settings, allowing easy adjustments of picture and parameters to suit user preferences without the need to interrupt gameplay.

Although the Samsung QN95D does not support Dolby Vision – which is quite obvious for Samsung televisions – it does offer the HGiG feature, which ensures appropriate picture quality in HDR games, in line with the creators' vision.

In terms of features for gamers the TCL A400 Pro performs brilliantly. The TV has practically everything you can expect from a gaming TV today: support for 4K at high refresh rates, VRR, ALLM, correct implementation of HDR formats in games including Dolby Vision, and HGiG. That means it works well with both next-generation consoles and a PC. Another plus is the presence of the Game Bar, a special panel with the most important settings for gamers. From it you can quickly check basic information about the signal, refresh rate or active features, and also adjust the appearance and behaviour of some settings to suit your preferences. This solution may not change picture quality by itself, but it greatly improves the convenience of using the TV while gaming.

The only thing to complain about is the number of full HDMI 2.1 ports. The A400 Pro has only two such connectors out of the four available, and one of them also serves as eARC. In practice this means that if someone wants to connect two next-generation consoles and a soundbar, they may run into some limitations. In that scenario you will have to either swap devices or use additional equipment, such as an AV receiver or a soundbar with HDMI inputs. Even so, it is hard not to rate the A400 Pro very highly as a TV for gamers. The gaming feature set here is truly powerful.
