Hisense U7Q PRO vs TCL A400 PRO

U7Q PRO is truly a bright television. In synthetic tests, it achieved over 1500 nits, which is an outstanding result for this price bracket. Such brightness – at least in theory – allows it to display HDR content as intended by the creators, even in more demanding scenes with strong lighting. In practice, it performs very well, but not always perfectly. In bright scenes with large areas – like the test screen with intense sunlight from the film "Pan" – the U7Q PRO makes a huge impression. It can even dazzle with its light, which is definitely an advantage in the context of HDR content. Unfortunately, it doesn’t always manage to maintain this when there are many small bright details on a dark background. In such moments, the local dimming algorithms tend to dim some bright elements to maintain good blacks – and the side effect is that some details simply vanish from the frame. This is a classic compromise in mini-LED televisions – and the U7Q PRO is no exception. With such a large number of dimming zones, however, one could have hoped for a slightly more mature algorithm responsible for their control. Fortunately, the overall perception of HDR content is very positive. The U7Q PRO is not only bright but also colourful, thanks to the PFS LED (QLED) coating, the coverage of the DCI-P3 colour palette is at 95%, and BT.2020 around 73%.

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 deliver a noticeably more appealing picture than in SDR. However, it’s not a level that dazzles by brightness alone. The A400 Pro is not one of those TVs that bombard the viewer with a powerful flash in every dramatic scene. The biggest limitation is visible with small bright elements on a dark background. Because of fairly aggressive zone control, 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. It should be added, though, that this isn’t done without reason. The A400 Pro does this to keep black levels as deep as possible and to limit the halo effect around bright objects. It’s a deliberate compromise: the TV more often opts for deeper blacks rather than maximising point highlights. On the one hand this is understandable, especially given a 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, delivers suitably saturated colours. Our measurements showed about 94% coverage of the DCI-P3 gamut and around 74% of BT.2020, which is a solid result for this class.

We tested the U7Q PRO in the best possible picture mode that this model offers – Filmmaker Mode. And indeed, this mode performs the best in terms of colour reproduction. But that doesn’t mean it’s perfect. In our test unit, both in SDR and HDR content, the image had a slightly cooler tone. The white balance was shifted towards blue, which made the overall image feel a bit "cooler." It may not be glaring, but it is definitely noticeable – particularly on white backgrounds, which instead of being neutral, seemed slightly bluish. Additionally – as we mentioned earlier – the television has a tendency to slightly brighten and oversaturate the image, which is also confirmed by the gamma and EOTF charts. All of this together means that without calibration, the image may appear somewhat unnatural – too cool, with slightly exaggerated dynamics. That’s why we decided to perform our own calibration – and you can see its effects and charts below.

As usual, we carried out colour measurements in the best‑tuned picture mode, Filmmaker Mode, the one intended to be closest to the creators’ intentions. The A400 Pro, of course, also offers other picture modes, but in practice they show much larger colour errors and interfere more with the image character. So we won’t cover them in detail in this part of the review. How does the factory colour reproduction fare? In short: really very well. In fact, looking at our measurements, it’s excellent. Both the white balance and the luminance response were set surprisingly precisely. The errors were so small that during the measurements we genuinely rubbed our eyes in surprise. Such good factory settings don’t happen often, even in televisions running Filmmaker Mode. All the more reason to praise TCL, because the A400 Pro straight out of the box can produce an image very close to how the source material should look. The results were so good you could easily think someone had already given this unit extra attention and tried to calibrate it. Our one bit of nitpicking comes down to a single issue. In SDR material the image was slightly brighter than the reference for a dark room, because the factory gamma was set closer to 2.3 than 2.4. It’s not a large error and most viewers probably won’t even notice it. We should note, however, that we are talking about our specific test unit. There can always be some variation in factory colour between individual units, production batches or screen sizes. We do not assume every A400 Pro will look identical straight out of the box.

Thanks to calibration, we've managed to tame the white balance in SDR and HDR content. For SDR material, the effect is really quite good – the image becomes neutral, cohesive, and simply pleasant to watch. Everything looks the way it should.

HDR performs a bit worse. Although the white balance looks correct and overall the image gains naturalness, unfortunately, the delta E errors are still noticeable. Why? Because Hisense's U7Q PRO model does not give us full control over how the television manages brightness in HDR mode. And this is where the limitation arises. When we look at the EOTF curve for HDR content, it clearly shows what we mentioned earlier – at the beginning of the graph, there’s a noticeable drop, meaning the television darkens the smallest portions more than it should. On the other hand, those brightest elements can be overly bright. As a result, some details are lost, others are too aggressive, and overall control over brightness doesn't always align with what we’re trying to achieve during calibration.

Does the image look better after calibration? Definitely, yes, in terms of colour. But when it comes to brightness management in HDR, one must accept that the Hisense U7Q PRO will still do it in its own way.

Despite the outstanding factory tuning, we couldn't resist checking how the TCL A400 Pro would respond to professional calibration. With such a strong starting point, we were especially curious whether we could squeeze even more from this TV. And here we have to boast: we managed to bring our sample to absurdly low colour errors. Results below 1 are something you don't see every day, even on very good TVs. Such outcomes are more often 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 after calibration simply excelled. The only thing we can pick on after closer analysis concerns the brightness response. The TV can vary the luminance level depending on the content being displayed, and quite often the picture is a little darker than it should be according to the reference. This most likely stems from the way the Mini-LED backlight and the local dimming algorithms work in this model. That said, it doesn't ruin the overall impression, because in terms of colour precision the A400 Pro after calibration reached a level that was genuinely hard to expect.

If someone happens to come across older materials where the banding issue arises – Hisense has a solution for that. In the U7Q PRO, we find a feature called "Smooth and Gradient Picture". Set to the "Medium" level, it works really well – eliminating most gradient problems without smoothing the entire image like a blur in Photoshop. 😉 Film grain remains, details don't disappear – that's exactly how it should work. Well done on the implementation!

As for scaling weaker materials, it's simply good. It's not at the level of the most expensive TVs with advanced upscaling, but older content looks good. There is some minor banding at very low resolutions, but that's perfectly normal and hard to avoid. On the plus side – even with the oldest materials, there is no overscan effect, the image isn't cropped or artificially stretched.

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’s hard to call it anything clearly above standard. The upscaling itself is acceptable: edges are fairly well smoothed, the picture does not look overly sharp or “pixelated”, and lower-quality material can be watched without major discomfort. At the same time the overall image has a slightly soft character and you don’t see the kind of precision that the best image processors in more expensive TVs can offer.

Handling of tonal transitions caused by heavy compression is much worse. TCL equipped the A400 Pro with a “Gradual Smoothing” feature that in theory should reduce visible colour banding and artefacts in lower-quality material. In practice, however, its effectiveness is very limited. It does not improve tonal transitions in any noticeable way, and at higher settings it can further smooth image detail, giving it an artificial, slightly blurred character. For that reason we think it’s best to leave this feature off. The A400 Pro copes decently with basic image scaling, but if you often watch heavily compressed material with visible posterisation, this model will not be one of the best choices.

“Speed” – this word was most frequently mentioned during our tests of the U7Q PRO. The television is equipped with a 165 Hz panel, which in itself is impressive – especially considering we’re talking about a mid-range model. Of course, PC gamers will benefit the most from its full capabilities, but even during everyday viewing, it’s clear that this is a fast and efficient panel. Like most modern televisions, the U7Q PRO can also enhance the smoothness of films that were originally recorded at 24 frames. In the menu, we find a slider that allows us to adjust the effect to our own preferences – from a more cinematic feel, with subtle motion, to a stronger smoothing with the characteristic “soap opera effect.”

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 most consoles, as well as many sports broadcasts and high-motion sources, are limited to today. In that range the TV performs quite well. Motion clarity is really good, especially after properly configuring the motion smoothing. The 'Motion Clarity' function improves smoothness. Its settings include two sliders that let you tailor the motion smoothing to your preferences, separately for low-frame-rate and high-frame-rate content. This allows you to achieve either a more cinematic look or a noticeably smoother image. If you don't want to fiddle with manual configuration, you can use built-in presets such as Low, Medium, High, Cinema or Nature.

Hisense U7Q PRO is a TV that seems to have been designed with gamers in mind. We have practically everything that can be expected from a gaming screen: variable refresh rate (VRR), automatic mode (ALLM), and as many as four HDMI 2.1b ports with full bandwidth of 48 Gb/s. Additionally, there’s a clear and quite functional Game Bar, as well as a well-implemented Dolby Vision GAMING mode that works seamlessly with Xbox Series S and X consoles.

Sounds like the ideal? Well, almost. Unfortunately, Hisense has still not implemented the HGiG feature, which is the system's tone mapping limitation on the TV's end. This means that when configuring HDR brightness on the console, we do it “by eye” or look for settings in online guides, as the screen does not display its actual brightness range. It’s a shame – because HGiG makes it easier to match the console to the TV and helps avoid overexposed or too dark scenes in HDR games.

Fortunately, the other elements work very well. Input lag is low, responsiveness is excellent, and the handling of other features is faultless. And although not everything worked perfectly, the U7Q PRO can still be confidently recommended to gamers.

In terms of gaming features the TCL A400 Pro performs brilliantly. The TV has practically everything you’d 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‑gen consoles and PCs. Another plus is the inclusion of a Game Bar, a dedicated 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 customise the appearance and behaviour of some settings to your preferences. It’s 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 criticise 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 serves as eARC. In practice this means that if you want to connect two next‑gen consoles and a soundbar you may run into some limitations. In that scenario you’ll need to either swap devices or use extra equipment, such as an AV receiver or a soundbar with HDMI inputs. Even so, it’s hard not to rate the A400 Pro very highly as a gaming TV. The gaming feature set here is genuinely powerful.
