XIAOMI A PRO 2026 vs TCL A400 PRO

If you are hoping for a cinematic HDR effect in the new Xiaomi A Pro 2026, you better quickly cool your expectations. This TV is simply too dark to fully convey the capabilities of contemporary movies or series prepared for the highest quality picture. Our measurements showed brightness in the range of 200-300 nits, which are values that suit SDR content more than ambitious HDR productions. In practice, this means that most movies look okay, but they definitely won’t give you the "wow" effect that other TVs deliver. Fortunately, not everything is lost – a plus here is the use of the PFS LED filter, which is a solution similar to the quantum dot known from QLEDs. Thanks to this, the coverage of the DCI-P3 color gamut reaches about 94%, resulting in vibrant, saturated colors in the vast majority of materials.

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.

What we saw in Filmmaker mode surprised us greatly – and unfortunately not in a good way. The mode advertised as Hollywood standard resembled more of a display in a store window. The white balance was shifted towards blue, leading to huge color errors and the effect of washed-out scenes in SDR content. It was a little better, though far from perfect, in HDR materials. There, problems were also visible – color saturation and the entire palette consistently shifted towards cooler tones, which made the image appear more artificial and cold rather than cinematic. In other words: even in Filmmaker mode, which should be the showcase of this television, we got a result far from expectations.

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.

Even though Xiaomi is not a brand associated with top-of-the-line televisions, it must be acknowledged that even in a budget model like the A Pro 2026, the manufacturer left quite a few calibration settings. After a few adjustments, the SDR picture gained a completely new character. The colors stopped veering into blue tones, the whites became more natural, and most errors dropped to a practically invisible level. As a result, SDR content looked very good, surprisingly so for this price range.

It was somewhat different with HDR material. Here, it was immediately noticeable what we had already mentioned - the overexposure of bright scenes and issues with balance control. Calibration only helped partially because the limitations of the panel itself played a role. However, it should be emphasized that in the case of SDR, the television transformed beyond recognition, and in a decidedly positive direction.

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 in the Xiaomi A Pro 2026 are not among the strengths of this model. One might expect that since the TV wasn’t designed to achieve record brightness levels, the manufacturer would have opted for a more robust processor and a set of features that would "enhance" lower quality images. Unfortunately – we were also quite disappointed here. On the plus side, there is reasonably decent upscaling that handles HD materials and elevates them to 4K in an acceptable manner. However, this is where the list of advantages ends. The TV does not offer any features to improve tonal transitions or smooth out digital imperfections, so in most cases, we get a raw image, exactly as we deliver from an external source. On a large screen, this lack of support makes lower quality materials look simply bland. An additional problem is the phenomenon of overscan. When watching older materials, it sometimes happens that part of the image is cut off, which only intensifies the impression that Xiaomi still has a lot to catch up on 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.

The motion fluidity in the Xiaomi A Pro 2026 is an interesting compromise that results from the hybrid matrix used here. At the native resolution of 4K, the maximum refresh rate is 60 Hz – sufficient for those who mainly watch movies and series. It is precisely for them that the manufacturer added a motion smoother, allowing users to adjust the image to their own preferences – one can opt for greater fluidity or leave the more "cinematic" frames depending on the settings.

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.

Indeed – since Xiaomi has added the "Game Boost 120 Hz" feature here, one might expect that they would follow up with a solid gaming package. Unfortunately, reality quickly dampens that enthusiasm. Aside from this mode (which, it must be said, is a great addition in a budget build), we have just a rather bizarre player panel. It's hard to call it a fully-fledged "game bar" – it's more of a simple overlay on the TV Menu with limited options. And that would be about it. There is no ALLM, so the TV won't automatically switch to game mode. There is no VRR, so you can forget about smooth frame synchronization. We also won't find support for Dolby Vision in games or the HGiG format, which are becoming increasingly standard on consoles. In short: apart from Game Boost 120 Hz, which does indeed make playing more enjoyable in 1080p or 1440p, the Xiaomi A Pro 2026 offers nothing particularly appealing to gamers.

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.
