Panasonic Z95A vs TCL A400 PRO

Panasonic Z95A demonstrates class when it comes to HDR performance. In brightness tests, it reaches a level of 1800 nits, which has a real impact on watching movies. Scenes from Life of Pi or Gemini Man look great – the television effortlessly reproduces details and the intensity of bright spots, impressing with its power. In more demanding moments, like the final scene from The Meg, one can see how bright light floods the screen. In such moments, brightness drops, which is typical for organic matrices. Nonetheless, a result around 1000 nits can still be considered excellent, still providing very good picture quality. Additionally, the television offers excellent coverage of wide color gamuts – up to 98.6% for DCI-P3 and 74.5% for BT.2020. This ensures that colors are not only vibrant but also deeply saturated, allowing full appreciation of the richness of details, especially in HDR scenes. Such coverage makes colors appear more realistic, and the HDR effect gains in intensity and accuracy. All this impressive HDR effect is thanks to MLA technology, which enables achieving such high luminance and excellent image detail. Thanks to this, the Panasonic Z95A offers HDR at a level that truly makes a difference.

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 best picture mode in the Panasonic Z95A is undoubtedly the Filmmaker mode. It is a mode that offers quite good image reproduction, but it is not free from certain errors that need improvement. First of all, the white balance, both for 4K and HD content, tends to show a dominance of red and blue colors. This causes a slight pinkish tint in the image, particularly noticeable in bright, white scenes. Such deviations can be seen in the comparative photo below, which illustrates this problem well. The Colour Checker test also confirms these discrepancies, showing slight shifts of the dots towards the mentioned hues.

In terms of gamma brightness characteristics, it performs very well, with only minor issues when lightening small details. The EOTF curve, which is responsible for controlling brightness in 4K HDR content, poses greater difficulty. Here, a slight boost in brightness above the reference value can be observed, making the image sometimes too bright, especially in more demanding scenes. Although the Filmmaker mode is definitely the best choice in the Z95A, these aspects require refinement to fully exploit the potential of the television.

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, Panasonic Z95A shows its full potential, offering an almost perfect image. The television provides great adjustment capabilities, which we have fully utilized. The white balance after calibration is presented almost perfectly, and errors in SDR content at the level of 0.5 fall within an absolutely reference standard. The same is true for 4K HDR content – any pink tint on the screen has been completely eliminated, and the white balance is now exemplary.

The color palette and Colour Checker test confirm the excellence of the calibration. Errors below 2 is a result that will satisfy both professional calibrators and enthusiasts of cinema-quality images. Significant changes have also occurred in brightness characteristics – the EOTF curve has been leveled, eliminating previous issues with excessive image brightness. And the small error in gamma has been reduced.

Before calibration, the image was acceptable, but now it is a completely different league. It is a true feast for the eyes, the quality of which is hard to compare to anything else. Panasonic Z95A, after fine-tuning the settings, becomes a true master of color reproduction.

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.

In the case of lower quality materials, the "Gradient Smoothing" function is responsible for smoothing tonal transitions. The best results are achieved with an intermediate setting – although they are not spectacular, the function works correctly and does not introduce unwanted effects into the image. It can be rated as average, but sufficient to improve the quality of tonal transitions.

As for digital processing, or upscaling, the image looks surprisingly good. It is vibrant and pleasant to the eye, making lower quality content, such as standard television or YouTube, look quite decent. However, minor issues can be noticed, such as "jaggies" on edges, e.g. branches in the background. Nevertheless, this does not significantly impact the overall viewing experience, and the television handles this material in an acceptable manner.

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.

Panasonic Z95A, with its 144 Hz panel, offers excellent image smoothness. For films, there is the "Intelligent Frame Creation" feature, which enhances fluidity and reduces motion blur. The user has two sliders at their disposal: "Motion Blur Reduction" – responsible for clearer and sharper details in fast-moving scenes. "Film Smoothness" – adds smoothness by creating additional frames between the originals, making the motion look smoother and more natural with a "soap opera" effect.

As a result, viewers can adjust the settings to their own preferences. Films and less dynamic materials appear smooth and natural, which should satisfy most users.

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.

Panasonic Z95A this year shows that the manufacturer has made a huge leap forward in terms of support for gamers. The television offers practically everything one could expect from a device in this category. Support for ALLM (Auto Low Latency Mode) and VRR (Variable Refresh Rate) ensures smoothness and no tearing in dynamic games. The 144 Hz panel allows for incredible fluidity, and the additional support for resolutions other than 4K provides greater flexibility, which is a significant plus for gamers using various setups.

Attention should also be paid to the unique and somewhat specific "Game Bar." Its intuitive interface stands out from the competition and allows quick adjustments to key settings such as VRR, brightness level, or picture mode without interrupting gameplay.

However, in this class of device, there is a slight disappointment – the Panasonic Z95A offers only two HDMI 2.1 ports, instead of four. This is definitely insufficient for a premium television, especially at a time when many people have more than one device requiring full HDMI 2.1 support, such as a next-gen console or a high-end computer. In this category, it is hard to accept, especially given the high aspirations of this model. Despite this, the television is an excellent choice for gamers, offering versatility and functionality at the highest level.

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.
