TCL A400 PRO vs Sony BRAVIA 7 II

The TCL A400 Pro is a moderately bright TV. Its peak brightness reaches about 600 nits. That level already allows for a real HDR effect and in many movies it does produce a noticeably more attractive picture than SDR. However, it is not a level that overwhelms by brightness alone. The A400 Pro is not one of those TVs that "attack" the viewer with a powerful flash in every dramatic scene. The biggest limitation is visible with small bright elements on a dark background. Due to rather aggressive control of the dimming zones, the TV can significantly reduce their brightness — in extreme cases down to around 100 nits. That means small lights, sparks, stars, or single highlights can be much less visible than they should be. That said, this is not done without reason. The A400 Pro does this to keep blacks as deep as possible and to limit haloing around bright objects. It's a deliberate compromise: the TV more often chooses deeper blacks over maximally bright, point-like highlights. On one hand this is understandable, especially with a limited number of dimming zones, but on the other hand you should be aware that the HDR effect will not always be as strong as the peak brightness alone would suggest.

On the plus side, the colors are worth noting. The PFS LED filter used here, marketed by the manufacturer as QLED, produces suitably saturated colors. Our measurements showed about 94% coverage of the DCI-P3 gamut and about 74% of BT.2020, which is a solid result for this class.

The Sony Bravia 7 II handles HDR very well and, above all, is simply a bright TV. In the proper "Professional" viewing mode we measured about 2000 nits of peak brightness, so the panel's capabilities are really substantial. Of course, with Mini-LEDs the result on a test pattern is only part of the story, because a lot depends on how the TV controls the backlight in real scenes. And here Sony's algorithms perform really well. Depending on the scene, the brightness we measured in movies ranged from around 1100 up to 1700 nits. That's already a level at which HDR has the proper punch and bright effects can really impress. It's not perfect in every situation, though. With small bright elements on a very dark background the Bravia 7 II clearly prioritizes maintaining good black levels, which can cause their brightness to drop to around 500 nits. It still looks good, but you can see the TV doesn't always operate without compromises.

Colors

The second thing that has a huge impact on the HDR effect is, of course, color. And this is where True RGB technology was supposed to bring one of the biggest changes. Looking at the panel's raw capabilities, the Bravia 7 II performs very well. We measured about 98% DCI‑P3 coverage and 88% BT.2020, so the potential to display highly saturated colors is really large. However, in RGB TVs the situation is a bit more complex. When we performed the same measurements with a movie background applied, the gamut coverage dropped to about 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 colors. In most scenes the Bravia 7 II handles this well and colors retain high saturation. The biggest differences are seen in shades of blue, where samples start to deviate more noticeably from the reference values and coverage is weaker than for the other primary colors. So True RGB does offer real additional possibilities here, but like with brightness, much depends on what is actually happening on the screen.

As standard, we carried out color measurements in the best-calibrated mode, Filmmaker Mode, the one that is supposed to be closest to the creators’ intent. The A400 Pro, of course, also offers other picture modes, but in practice they suffer from much larger color errors and alter the image character more strongly. We won’t go into those modes in detail in this part of the test. So how does the factory color reproduction perform? In short: really very well. In fact, looking at our measurement results, it’s excellent. Both the white balance and the luminance response were set surprisingly precisely. The errors were so small that during testing we genuinely rubbed our eyes in disbelief. Such good out-of-the-box settings don’t happen often, even in TVs operating in Filmmaker Mode. All the more reason to praise TCL, because the A400 Pro right out of the box can produce an image very close to how the source material should look. The results were so good that you could easily think someone had already paid extra attention to that unit and tried to calibrate it.

Our nitpicking really comes down to just one thing. In SDR content the image was slightly brighter than the reference for a dark room, because the factory gamma was set closer to 2.3 than to 2.4. It’s not a big error and most viewers probably won’t even notice it.

However, it should be noted that we’re talking about our specific review sample. With factory colors there can always be some variation between units, production batches, or screen sizes. So we don’t assume that every A400 Pro will look identical straight out of the box.

To evaluate the out-of-the-box colors we chose Professional mode, because it performs best among the available settings. It's not perfect, though. In SDR the white balance leans slightly toward magenta, so some scenes look a bit warmer and less neutral than they should. A bigger issue is the gamma, which sits closer to 2.5 than 2.4. That makes the image a bit too dark in places, especially in the midtones. In HDR the situation is better. As brightness increases there is a bit too much red, but it's not a fault that stands out during viewing. Overall, Professional mode is a good starting point, although you can get a little more out of it with calibration.

Despite its excellent factory tuning, we couldn't resist checking how the TCL A400 Pro would respond to a professional calibration. Since the starting point was so good, we were even more curious whether we could squeeze even more out of this TV. And here we have to boast: we managed to bring our unit to absurdly low color errors. Results below 1 are something you don't see every day, even on very good TVs. Such results are more often associated with professional reference monitors than with a lifestyle TV for the living room. In terms of white balance and color reproduction, the A400 Pro after calibration simply performed outstandingly. The only thing we can pick at after a deeper analysis concerns the brightness behavior. The TV can manipulate luminance levels depending on the content being displayed, and quite often the image is a bit darker than it should be according to the standard. This most likely stems from the way the Mini-LED backlight and local dimming algorithms work in this model. However, that doesn't spoil the overall impression, because in terms of color precision alone the A400 Pro after calibration reached a level we really didn't expect.

After calibration the Bravia 7 II can look significantly better. First of all, we managed to set the white balance very well, both in SDR and HDR. Gamma can also be improved, and after correction it runs very close to the reference value. For most users, those changes will have the biggest impact on the picture. There is, however, a limitation when it comes to colors. On the Bravia 7 II Sony does not provide access to a classic CMS that would let us adjust individual hues separately. A lot is therefore left in the hands of the algorithms controlling the True RGB backlight. If the TV reproduces a specific color inaccurately, we are not always able to do anything about it. In our measurements this is most evident with some reds and blues, where errors can still be quite large. That does not, however, diminish the value of calibration. Correctly setting the white point and gamma strongly affects the overall image, so even without the ability to precisely tweak every color the difference compared with the factory settings is noticeable.

Digital video processing is unfortunately one of the weaker points of the TCL A400 Pro. That doesn't mean the TV performs badly, but it's hard to call it anything clearly above standard. The upscaling itself is adequate: edges are smoothed fairly well, the image doesn't look overly sharp or pixelated, and lower-quality content can be watched without major discomfort. At the same time the overall look is slightly soft and it lacks the precision that the best image processors in more expensive TVs can deliver.

Much worse, however, is its handling of tonal transitions caused by heavy compression. TCL equipped the A400 Pro with a "Gradual Smoothing" feature that in theory should reduce visible color banding and artifacts in lower-quality content. In practice 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's best to leave this feature off. The A400 Pro handles basic image scaling decently, but if you often watch heavily compressed content with visible posterization, this model won't be one of the best choices.

Upscaling and digital processing are among the Bravia 7 II's strongest assets and one of Sony's biggest advantages over the competition. Sony has handled digital image processing well for years, and it shows here too. Above all, the "Smooth Gradation" function works very well; it can smooth weak tonal transitions in lower-quality content. It's safest to set it to Low, but we'd comfortably recommend Medium as well. The effect is stronger then, and the TV still handles details very delicately. Some fine detail may be slightly smoothed, but Sony does it much more subtly than many other brands. The upscaling itself also performs very well. Lower-resolution sources are well upscaled to 4K; the picture looks clean and retains a lot of detail. Of course the TV won't magically turn native HD material into true 4K, but the Bravia 7 II does a very good job with what can be extracted from such a source.

The TCL A400 Pro is equipped with a 144 Hz panel, but in practice we're most interested in how it performs at 120 Hz. That's the refresh rate used by most consoles today, as well as many sports broadcasts and high-frame-rate content. In this range the TV performs quite well. Motion clarity is really good, especially after properly configuring the motion smoothing. The "Motion Clarity" feature improves smoothness. Its settings include two sliders that let you tailor the motion smoothing to your preferences — separately for lower- and higher-frame-rate material. That way you can achieve either a more cinematic look or a noticeably smoother picture. If you don't want to tweak settings manually, you 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 smoothness it delivers everything you’d expect from a TV in this class. With sports or games at 120 fps the picture is appropriately smooth, and for movies Sony provides an advanced motion smoothing feature. You can adjust the level of interpolation separately and decide whether you want to keep a more cinematic motion or achieve noticeably smoother motion. The issue of motion blur is a bit worse. The VA panel used isn’t among the fastest, and you can notice a slight trail behind moving objects, especially on darker backgrounds. It’s not at a level that will be highly distracting during normal viewing, but last year’s Bravia 7 performed better in this respect and had a noticeably faster panel.

When it comes to features for gamers, the TCL A400 Pro performs excellently. The TV has practically everything you can expect from a gaming TV today: 4K support at high refresh rates, VRR, ALLM, correct implementation of HDR formats in games, including Dolby Vision, and HGiG. Because of that it works well with both next-gen consoles and PCs. Another plus is the inclusion of a Game Bar, a special panel with the most important settings for gamers. From it you can quickly check basic signal information, refresh rate, and active features, and also adjust the look and behavior of some settings to your own preferences. This is a solution that 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 ports out of four, and one of them also functions as eARC. In practice this means that if someone wants to connect two next-gen consoles and a soundbar, they may hit some limitations. In that scenario you'll have to either swap devices or use extra equipment, for example an AV receiver or a soundbar with HDMI inputs. Despite this, it's hard not to rate the A400 Pro very highly as a gaming TV. The gaming feature set here is really powerful.

The Bravia 7 II essentially has everything you'd expect from a good console TV today. 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 low-latency mode. There's also a properly working HGiG, which means that after setting up HDR on the console the TV won't try to further brighten the image on its own. Just remember to turn off tone mapping in the TV's menu. Dolby Vision in game mode is another plus, especially for Xbox owners. Sony also includes its own Game Menu. From it you can quickly view key signal information, check VRR, or change gaming settings without digging through the TV's entire menu. The only thing missing from the feature list is support for 1440p at 120 Hz.

Our biggest complaint is not really with the features themselves, but with 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 via HDMI, in practice you have only one full HDMI 2.1 port left for a console or PC. With a single console that's fine, but with a PS5, an Xbox, and an audio setup it starts to get tight. That's hard to justify from Sony. Two HDMI 2.1 ports might be acceptable in cheaper TVs, but in a model of this class, especially in 2026, we'd expect all four ports to be HDMI 2.1.
