Philips PUS8500 vs TCL A400 PRO

When it comes to HDR performance on the PUS8560, one can confidently say that it is quite average. The brightness of the panel is around 350 nits, which we consider to be the absolute minimum for viewing content in this format. However, this is not a result that will impress viewers looking for the best possible image.

On the plus side, it is worth noting that the PUS8500 series – including the PUS8560/12 we tested – is marketed as a QLED television. And indeed, we can expect a wider color gamut here. This model is equipped with an additional filter (PFS), and the coverage of the DCI-P3 color space at around 90% should be sufficient for the majority of users. This filter works very similarly to quantum dots. As a result, the colors are quite well saturated. It’s not an outstanding result, but perfectly adequate for watching movies and series on streaming platforms.

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.

We tested the TV on the best available factory settings, which is in Film/Filmmaker mode – this is the mode we recommend for everyday viewing. Unfortunately, it is not without its flaws. Both in HD and HDR content, the image had a clear tendency to appear pinkish, caused by too much red and blue in the white balance. Another problem turned out to be excessive brightness of the image, which was confirmed by both the gamma chart and the EOTF curve. This characteristic was responsible for the loss of detail and washed-out colors in more challenging HDR scenes, as we mentioned earlier. Overall, this led to quite significant color reproduction errors – in extreme cases, the delta E value exceeded 7, while the threshold of visible errors for the human eye is about 3. This situation can be improved through calibration, and you can read about its effects below.

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.

The Dutch manufacturer offers quite a large dose of settings in their products, so as usual, we decided to dig a little into them. The effects are immediately visible – we managed to correct the white balance, which made the image stop appearing excessively pink. The brightness characteristics were also partially balanced, of course, within the limits that the television itself allows. The image is no longer overly vibrant, and the overall reception after calibration is definitely better than in the factory settings of the Filmmaker mode.

One could only criticize the characteristics of the EOTF curve, which still indicates that the image tends to lighten materials in HDR format. Despite our efforts, the darkest parts of scenes can still be too bright, and the brightest do not always reach their full contrast potential. However, it must be clearly stated that we are dealing with a typically budget construction – you cannot expect reference-quality reproduction of HDR content from it.

Calibration definitely helped this model – it improved the balance, toned down the aggressive color scheme, and brought the image closer to what one might expect from a well-configured movie mode. However, there are certain limitations that cannot be overlooked.

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.

Philips PUS8560 offers a feature that reduces posterization, hidden under the name "distortion reduction." And while it indeed serves its purpose by smoothing problematic tonal transitions, it operates a bit too broadly. In practice, it affects not only colorful gradients but also softens faces, clothing textures, and furniture surfaces. This decreases the authenticity of the image—especially in films where natural texture is of great importance. However, if someone is looking for smoothing at all costs, it's best to set this option to "Low." For cinema image enthusiasts—definitely not recommended.

On the plus side, the quality of upscaling older materials should be noted—the PUS8560 model handles them surprisingly well. The image maintains a natural softness without artificially enhanced sharpness. It is also worth mentioning that the television correctly displays very low-resolution content, avoiding problems with cropping the edges of the image (so-called overscan).

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 Philips PUS8560 is a television equipped with a 60 Hz refresh rate panel, which already limits its capabilities for displaying dynamic content. Watching sports or playing on a console is not one of the most enjoyable experiences. The situation is further worsened by the lack of any option to improve the smoothness of films. In the menu, we won't find settings that would allow for the activation of a motion smoother or even a slight motion smoothing in films recorded at 24 frames per second. You can imagine the effect. The picture may look jerky, especially in shots with panoramic camera movements.

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.

Although the Philips PUS8560 is not designed specifically for gamers, the manufacturer decided to equip it with several features that may prove useful when connecting a console. It includes automatic switching to game mode (ALLM), as well as a simple connection status information bar – the so-called Game Bar. While it does not make a particularly strong visual impression, it serves its purpose. The presence of variable refresh rate (VRR), operating in the range of 48 to 60 Hz, might come as a surprise. While this is not a wide range, in the case of less demanding games or titles with unstable fluidity, VRR can help reduce the stuttering effect. However, this is the only element that can be considered above the minimum.

It should be clearly stated that the PUS8560 is not hardware for gamers looking for a responsive screen and full support for modern console features. It lacks HDMI 2.1 ports, the refresh rate is limited to 60 Hz, and the panel's response time is not among the fastest. This model may be suitable at most for casual gamers who want to enjoy the Ambilight system.

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.
