Panasonic Z95B vs TCL A400 PRO

The HDR effect quality in the Panasonic Z95B is among the absolute best. Thanks to the latest generation panel, named Primary RGB Tandem OLED by the manufacturer, the television can achieve over 2000 nits of brightness in movie scenes. The effect is impressive and can amaze with its intensity of light, giving a sense of contact with the screen that goes beyond previous experiences. Similar feelings were only experienced during tests of the LG G5, Samsung S95F, or Philips OLED910. Of course, there are moments when the device's algorithms decide to limit luminance – this especially applies to full-screen bright sequences, such as the ending credits in the movie The Meg. Even then, the Z95B maintains a level of around 1500 nits, which is still an extremely impressive result. Thus, it can be said that HDR in this model has been brought to a masterful form. A significant step forward is also visible in the reproduction of the colour palette. The new tandem OLED panel does not yet match the best QD-OLED screens in terms of gamut coverage, but the gap between these solutions has significantly decreased. When watching films, the differences are subtle enough that under normal conditions it's hard to notice them, and the colours remain vibrant and saturated.

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.

The factory colour reproduction in Filmmaker mode, my dear friends, is a true phenomenon in the case of the Panasonic Z95B. I'm talking about our test sample, but the results were so good that it's hard to believe. The only detail that one could nitpick is a slight lack of blue in the white balance, but apart from that, the television straight out of the box presented an image like we have never seen in factory mode. Colour palette tests, Color Checker – everything indicated values below Delta 2. This is a much lower result than the threshold of human eye perception, which means, to put it simply, that the viewer has no chance of noticing serious deviations. It looks as if Panasonic actually calibrated this model at the factory stage. Of course, we cannot exclude the possibility that we got an exceptionally well-set specimen, but the result still makes a stunning impression. We are very strict when it comes to assessing factory calibration, and here our jaws simply dropped.

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.

The colour reproduction after calibration on the Z95B is a topic that’s hard to elaborate on, as there wasn’t much to do here. A slight adjustment of the white balance was enough to eliminate the lack of blue, and at that moment, the picture jumped to an almost reference level. It must be said that we haven’t had such a small range of adjustments in a long time. If any of you are particularly perceptive, you might notice minimal deviations in the EOTF curve, but this is more related to the functioning of the dynamic tone mapping feature we mentioned earlier. In reality, this isn’t a flaw, but a characteristic of this solution, which intentionally alters the brightness profile depending on the scene. In summary, we are extremely impressed. The Panasonic Z95B is a television that looks great right out of the box, and after calibration, it reaches a level where we really struggle to find anything to improve.

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.

Let's start with what works well. The upscaling in the Z95B is at a very high level – the image in lower resolutions is clear and sharp, and the only minor shortcomings are slight banding in some areas of the picture. It's also important that the television doesn't crop the material in any way and maintains its proportions, which is not always an obvious fact even in 2025.

The situation looks worse when it comes to digital processing. Features like "gradation smoothing" or "block noise reduction" essentially do not work – the tested material looked identical regardless of the settings. We might as well say that this feature simply doesn't exist. It's a bit disappointing, especially since Panasonic heavily promotes its HCX Pro AI II processor, boasting the presence of artificial intelligence improving image quality. Meanwhile, in such a basic matter, the television does not deliver a real effect and it looks weaker than one would expect from top-tier equipment.

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.

The OLED panel with very high refresh rates already provides an incredibly sharp image even in dynamic sports scenes, such as football or basketball matches, and the Z95B is no exception. It's also very important that the television is equipped with the proprietary motion smoothing system 'Intelligent Frame Creation'. Among the available sliders, the most crucial one turns out to be the one called 'film smoothness', as it allows for adjusting the motion to personal preferences with 24-frame content, meaning films – from a more 'choppy' appearance to a smooth, almost theatrical effect. It's a bit disappointing that Panasonic didn't opt to push the latest OLED panel to 165 Hz, as Samsung did with the S95F or LG with the G5, because we know that the panel is technically capable of it. On the other hand, it mainly benefits PC gamers, so in everyday viewing, it's not a significant drawback as we are limited to 120Hz.

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.

The Panasonic Z95B is fully equipped for gaming. Two HDMI 2.1 ports with a full bandwidth of 48 Gb/s guarantee support for everything you can expect from a modern screen. It features VRR frame syncing, an automatic game mode (ALLM), and full compatibility with HDR formats used in gaming. The TV supports both Dolby Vision for Xbox and the popular HGiG, which in this case has been implemented correctly, so it actually works as it should.

Although the brand is mainly associated with home cinema and equipment for filmmakers, there’s also space for gamer conveniences here. Onboard is the Game Bar (or rather Game Circles) – it looks a bit unusual visually, but it does its job and allows you to quickly check the most important image parameters. The only thing missing for complete satisfaction is actually having four HDMI 2.1 ports instead of two. It’s a minor detail, but with a TV of this class, one could expect a full set.

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.
