TCL A400 PRO vs Sony BRAVIA 7 II

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.

The Sony Bravia 7 II handles HDR very well and, above all, is simply a bright television. In the correct viewing mode, Professional, we measured around 2,000 nits of peak brightness, so the panel’s capabilities are truly significant. Of course, with Mini-LEDs a test pattern result is only part of the story, because a lot still depends on how the TV controls the backlight in real scenes. Here Sony’s algorithms perform very well. Depending on the scene, the brightness we measured in films ranged from roughly 1,100 to as much as 1,700 nits. That’s already a level at which HDR has proper punch and bright highlights can be genuinely impressive. It isn’t perfect in every situation, though. With small bright elements on a very dark background the Bravia 7 II clearly favours maintaining good blacks, which can cause their brightness to drop to around 500 nits. It still looks good, but you can see the TV does not always manage this without compromise.

Colours

The second thing that has a huge impact on HDR is, of course, colour. And this is precisely where True RGB technology was meant to bring one of the biggest changes. Looking at the panel’s capabilities alone, the Bravia 7 II performs very well. We measured about 98% DCI-P3 coverage and 88% BT.2020, so the potential to show strongly saturated colours is really large. In RGB TVs, however, the situation is a bit more complex. When we repeated the same measurements with a film background applied, palette coverage fell to around 92% DCI-P3 and 78% BT.2020. Those are still good figures, especially for an RGB Mini-LED TV, but they clearly show that the final result largely depends on how the algorithms control the three backlight colours. In most scenes the Bravia 7 II handles this well and colours retain high saturation. The biggest differences are visible in shades of blue, where samples begin to deviate more noticeably from reference values and coverage is weaker than for the other primary colours. True RGB therefore offers genuinely greater potential here, but, as with brightness, much depends on what is happening on screen.

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.

To evaluate the factory colours we chose the Professional mode, because it performs best among the available settings. However, it is not perfect. In SDR the white balance drifts slightly towards magenta, making some scenes look a little warmer and less neutral than they should. A bigger problem is the gamma, which sits closer to 2.5 than to 2.4. This makes the image a bit too dark in places, particularly in the midtones. In HDR the situation is better. As brightness increases a little too much red appears, but this is not an issue that is highly noticeable during viewing. Overall the Professional mode is a good starting point, although you can get a bit more out of it after calibration.

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.

After calibration the Bravia 7 II can look decidedly better. Above all, we managed to set the white balance very well, both in SDR and HDR. Gamma can also be improved, which after correction runs very close to the reference value. And in fact, for most users these changes will have the greatest impact on the picture. There is, however, a limitation when it comes to the colours themselves. In the Bravia 7 II Sony does not provide access to a classic CMS that would allow us to correct individual hues separately. A lot is therefore left in the hands of the algorithms controlling the True RGB backlight. If the TV misrepresents a particular colour, we are not always able to do anything about it. In our measurements this is most visible in certain reds and blues, where errors can still be quite large. This does not, however, undermine the point of calibration itself. Correctly setting the white point and gamma strongly affects the whole picture, so even without the ability to precisely correct every colour the difference compared with the factory settings is noticeable.

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.

Scaling and digital processing are among the strongest points of the Bravia 7 II and one of the bigger reasons to choose Sony over the competition. The manufacturer has been handling digital image processing well for years, and it shows here too. First and foremost, the 'Smooth Gradation' function works very well and can smooth out weak tonal transitions in lower-quality material. The safest setting is Low, but we would comfortably recommend Medium as well. The effect is stronger then, yet the TV still treats details very gently. Some fine details may be slightly smoothed, but Sony does this much more subtly than many other brands. The upscaling itself also performs very well. Lower-resolution material is well upscaled to 4K, the image looks clean and retains a lot of detail. Of course the TV will not magically turn native HD material into true 4K, but what can be extracted from such a source is handled really well by the Bravia 7 II.

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.

The Bravia 7 II uses a 120 Hz panel, so in terms of motion handling it delivers everything you would expect from a TV of this class. With sport or games at 120 fps, the picture is suitably smooth, and for films Sony provides an extensive motion interpolation system. You can therefore adjust the interpolation level separately and decide whether you want to preserve a more cinematic character to the motion or obtain noticeably smoother movement. The issue of motion blur itself is a little worse. The VA panel used is not among the fastest, and you can notice a slight trail behind moving objects, particularly on darker backgrounds. It is not at a level that greatly bothers during normal viewing, but last year’s Bravia 7 fared better in this respect and had a noticeably faster panel.

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.

Bravia 7 II has basically everything you’d expect today from a good console TV. It supports 4K at 120 Hz, VRR from 48 to 120 Hz and ALLM, so when you start a game the TV automatically switches to a low-latency mode. It also has properly working HGiG, which means that after configuring HDR on the console the TV won’t try to brighten the image further on its own. You just need to remember to turn off tone mapping in the TV’s menu. Dolby Vision in game mode is also a plus, especially useful for Xbox owners. Sony adds its own Game Menu. From it you can quickly check key signal information, verify VRR operation or change gaming-related settings without digging through the whole TV menu. The only thing missing from the feature list is support for 1440p at 120 Hz.

Our biggest reservation is not really about the functions themselves, but about the connectors. The Bravia 7 II has four HDMI ports, but only two of them support full HDMI 2.1 at 48 Gbps. One of those is also an eARC port. So if you connect a soundbar or AV receiver to the TV via HDMI, in practice you’re left with only one full HDMI 2.1 for a console or PC. With a single console that’s no problem, but with a PS5, an Xbox and an audio setup it starts to get tight. And this is hard to excuse for Sony. In cheaper TVs two HDMI 2.1 ports can still be acceptable, but in a model of this class, especially in 2026, we would expect a full set of four such ports.
