Sony Bravia 8 MK2 vs TCL A400 PRO

Thanks to its new QD-OLED panel, the Sony Bravia 8 II can reach an astronomically high brightness of around 2000 nits, which translates into near-reference quality for movies and series mastered in HDR. In test material like Life of Pi or Sicario 2 the effect is simply stunning, with details in bright areas remaining perfectly visible and nighttime scenes impressing with depth and contrast. It is not perfect, though. Compared with its toughest rivals, the Bravia 8 II shows a noticeable drop in brightness on full-screen, very bright frames. If you compare peak spot luminance with 100% white luminance in HDR mode, the Bravia 8 II can appear two to three times dimmer than the LG G5 or Samsung S95F models. In the scene from The Meg this was especially apparent, as the screen became noticeably dimmer than competing TVs. Despite this shortcoming, the Bravia 8 II’s results still place it among the market leaders. Its absolutely top-tier color gamut coverage deserves praise, with DCI-P3 at nearly 100% and BT.2020 close to 90%. These figures let HDR content reach its full potential and deliver cinema-like experiences at home.

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.

Out of the box the Bravia 8 II performs really well. In its best IMAX® Enhanced mode the TV renders colors pleasantly and naturally, though "good" here doesn't mean "best in class." The white balance definitely needs adjustment, as skin tones tend to shift slightly toward pinkish/cooler hues in both SDR and HDR content. We also noticed that the EOTF curve has a tendency to brighten the darkest parts of the picture. This likely comes from the manufacturer's desire to reveal as much detail as possible even in deep shadows. Is that a good approach? It's hard to say for sure, but one thing is clear: it's not an ideal solution.

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.

After calibration we mainly managed to eliminate the excessive cooling of the image caused by too strong a boost in blue. Reds became deeper and skin tones took on a natural, healthy look. Actors who had previously seemed "cold" now appear on screen much livelier and more convincing. One thing hasn't changed, however: analysis of the EOTF curve still shows the Bravia 8 II tends to brighten the darkest parts of the image. It's hard to say whether that's an intentional choice by the manufacturer or a result of the panel design and software. In practice this means scenes that filmmakers intended to remain in deep shadow can reveal more detail than intended. Despite that, the picture after calibration is clearly better — warm, natural colors and realistic skin tones simply make watching on the Bravia 8 II more pleasant to the eye.

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.

Upscaling and digital image processing are a real showcase for the Bravia 8 II. Sony has long been regarded as a master in this field, and this only reinforces that reputation. The company's proprietary XR processor can extract almost the maximum from lower-resolution sources, whether broadcast TV or an old DVD, the picture looks sharper, with more detail and better depth. Sure, if you feed it exceptionally poor-quality material (like our archival photo of the model), you won't get miracles, but for everyday viewing there's little to complain about.

The smooth gradation feature also performs very well. On the "Medium" setting it effectively smooths tonal transitions, eliminating banding in color and gray gradients while preserving film grain and fine image detail. It's precisely that balance between subtlety and effectiveness that keeps Sony TVs among the best on the market in this category.

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.

When it comes to motion handling, the Bravia 8 II is basically a done deal. The OLED panel with a 120 Hz refresh rate naturally delivers a very clean, sharp picture in fast-moving scenes, so there's little to complain about. What deserves special praise, though, is one of the best motion smoothing systems on the market. It lets you precisely tailor motion in films to your preferences, from subtle smoothing to an almost "theatrical" look, without the risk of artificial judder, image tearing, or annoying artifacts. It's one of those features you'll appreciate both when watching movies and during sports.

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.

Sony really learned from previous years, and with the Bravia 8 II it has put together a package of gamer-focused features that’s hard to call anything but "almost perfect." It includes everything you expect at this level: VRR, ALLM, Dolby Vision Gaming mode, HGiG, and even a handy Game Bar that lets you quickly check parameters and change settings without leaving the game. Also a plus is how smoothly and seamlessly these features work, with no delays and no odd stuttering. You just launch a game and everything looks as it should. Unfortunately, it’s not without a few caveats. The manufacturer still gives us only two full-bandwidth HDMI ports, so if you have a console, a PC, and another device like a soundbar connected via eARC, you’ll be swapping cables. It’s also surprising there’s no support for 1440p at 120 Hz, which is particularly important for Xbox players. Overall, though, this is one of those TVs you can comfortably place at the center of a gaming-focused living room and enjoy gameplay without major compromises.

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.
