Philips PUS8500 vs TCL A400 PRO

When it comes to the HDR effect on the PUS8560, it can fairly confidently be stated that it is very average. The panel brightness is around 350 nits, which we consider to be the absolute minimum for watching content in this format. However, this is not a result that will astonish a viewer searching for the best possible picture.

On the plus side, it is worth noting that the PUS8500 series – including the PUS8560/12 we tested – is advertised as a QLED television. And indeed, we can expect a wider colour spectrum here. This model is equipped with an additional filter (PFS), and a DCI-P3 colour coverage of around 90% should suffice for the majority of users. This filter works very similarly to quantum dots. As a result, the colours are quite well saturated. It is not an outstanding result, but it is entirely sufficient for watching films and series from streaming platforms.

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 produce a noticeably more attractive picture than in SDR. However, it is not a level that overwhelms with sheer brightness. The A400 Pro therefore isn’t one of those TVs that ‘attack’ the viewer with a powerful flash in every eye-catching scene. The biggest limitation is seen with small bright elements on a dark background. Because of fairly aggressive local dimming control, the TV can significantly reduce their brightness, in extreme cases even to around 100 nits. This means that small lights, sparks, stars or individual highlights can be much less visible than they should be. It’s worth adding, however, that this isn’t without reason. The A400 Pro does this to maintain as deep a black level as possible and to limit the halo effect around bright objects. So it’s an intentional compromise: the TV more often opts for deeper blacks rather than maximally bright, point-like highlights. On one hand this can be understood, especially given the 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, allows for suitably saturated colours. Coverage of the DCI-P3 gamut measured around 94%, and BT.2020 around 74%, which is a solid result for this class.

We tested the television with the best available factory settings, namely 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 noticeable tendency to a pink tint, caused by an excessive amount of red and blue in the white balance. Another issue turned out to be excessive brightness in the image, which was confirmed by both the gamma chart and the EOTF curve. This feature was responsible for loss of detail and washed-out colours in more challenging HDR scenes that we mentioned earlier. The overall result led to significant colour reproduction errors – in extreme cases, the delta E value exceeded 7, while the threshold for visible errors for the human eye is around 3. This situation can be improved with calibration, and you can read about its effects below.

As standard, we performed colour measurements in the best‑tuned Filmmaker Mode, the mode that is designed to be closest to the creators' intentions. The A400 Pro of course also offers other picture modes, but in practice these come with considerably larger colour errors and interfere more with the character of the image. Therefore we will not deal with them in detail in this part of the test. So how does the out‑of‑the‑box colour reproduction fare? In short: really very good. Actually, looking at our measurement results, downright excellent. Both the white balance and the luminance response were set surprisingly precisely. The errors were so small that during measurements we genuinely rubbed our eyes in amazement. Such good factory settings do not happen often, even in TVs operating in Filmmaker Mode. All the more credit is due to TCL, because the A400 Pro right out of the box can deliver an image very close to how the source material should look. The results were so good that one could easily think someone had already given this unit extra attention and tried to calibrate it.

Our nitpicking really comes down to just one thing. In SDR content the image was slightly brighter than the dark‑room reference intends, because the factory gamma was set closer to 2.3 than to 2.4. This is not a large error and most viewers will probably not even notice it.

It should, however, be noted that we are talking about our specific test sample. With factory colours there can always be some variation between units, production batches or screen sizes. We do not assume, therefore, that every A400 Pro will look identical straight out of the box.

The Dutch manufacturer offers quite a sizable amount of settings in its products, so as usual, we decided to tinker with them a bit. The effects are immediately noticeable – we managed to correct the white balance, which made the image stop appearing excessively pink. The brightness characteristic has also been partially evened out, of course, within the limits set by the television itself. The image is no longer overly exaggerated, and the overall reception after calibration is definitely better than in the factory settings of the Filmmaker mode.

One could only critique the EOTF curve characteristic, which still indicates that the image has a tendency to brighten HDR materials. Despite our efforts, the darkest parts of scenes are still sometimes too bright, and the brightest ones do not always achieve their full contrast potential. However, it must be clearly stated that we are dealing with a typically budget construction – one cannot expect reference-level reproduction of HDR content from it.

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

Despite its superb factory calibration, we couldn't resist checking how the TCL A400 Pro would respond to professional calibration. Since the starting point was so good, we were all the more curious whether there was anything more to be had from the TV. And here we must boast: we managed to reduce our unit's colour errors to absurdly low levels. Measurements below a value of 1 are not something you see every day, even in very good TVs. Such results are more commonly 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 therefore simply performed exceptionally well after calibration. The only gripe we have after closer analysis relates to the luminance behaviour. The TV adjusts luminance depending on the content being displayed and quite often the picture is slightly darker than the reference calls for. This is most likely due to the way the Mini-LED backlight and local dimming algorithms operate in this model. However, this does not spoil the overall impression, because in terms of colour accuracy alone the calibrated A400 Pro showed a level that was really hard to expect.

Philips PUS8560 offers a function for reducing posterization, hidden under the name "distortion reduction". And although it indeed fulfills its role by smoothing out problematic tonal transitions, it works a bit too broadly. In practice, it affects not only colourful gradients but also softens faces, the textures of clothing, and the surfaces of furniture. This compromises the authenticity of the image – especially in films where natural texture is very important. However, if someone is looking for smoothing at all costs, it's best to set this option to "Low". For cinema image enthusiasts – we definitely do not recommend it.

On the positive side, the quality of upscaling older materials is noteworthy – the PUS8560 model handles them surprisingly well. The image retains its natural softness, without artificially boosted sharpness. It is also worth mentioning that the television correctly displays content with very low resolution, avoiding issues with image edge cutting (so-called overscan).

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 is hard to call it anything clearly above average. The upscaling itself is adequate: edges are smoothed fairly well, the picture does not look overly sharp or "pixelated", and lower-quality content can be watched without much discomfort. At the same time, the overall image is slightly soft and lacks the precision offered by the best image processors in more expensive TVs.

Much worse, however, is how it handles tonal transitions caused by strong signal compression. TCL has equipped the A400 Pro with a "Gradual Smoothing" feature that, in theory, should limit visible colour banding and artifacts in lower-quality material. In practice, though, 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 is best to leave this feature off. The A400 Pro copes decently with basic image scaling, but if you often watch heavily compressed content with noticeable posterisation, this model will not be among the best choices.

The Philips PUS8560 is a television equipped with a panel featuring a refresh rate of 60 Hz, which immediately limits its capabilities in terms of displaying dynamic content. Watching sports or playing on a console is not particularly enjoyable. 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 us to enable a motion smoother or even a slight motion smoothing for films recorded at 24 frames per second. You can imagine the effect. The image can appear jerky, especially in shots with panoramic camera movements.

The TCL A400 Pro is equipped with a 144 Hz panel, but in practice we are most interested in its behaviour at 120 Hz. That is the frequency most consoles are limited to today, as well as many sports broadcasts and high-frame-rate content. At that rate the TV performs quite well. The sharpness of moving objects is really good, especially after properly configuring the motion smoothing. The "Motion Clarity" function is responsible for improving smoothness. Its settings include two sliders that let you tailor how the motion smoothing operates to your preferences, separately for lower and higher frame-rate material. This makes it possible to achieve both a more cinematic look and a noticeably smoother picture. Those who do not want to fiddle with manual configuration can use presets such as low, medium, high, cinema or nature.

Although the Philips PUS8560 is not designed with gamers in mind, the manufacturer has decided to equip it with a few features that may prove useful when connecting a console. On board, we find automatic switching to game mode (ALLM), as well as a simple connection status information bar – the so-called Game Bar. It does not make a particularly strong visual impression, but it serves its purpose. The presence of variable refresh rate (VRR), operating in the range of 48 to 60 Hz, may come as a surprise. While this is not a wide range, in the case of less demanding games or titles with unstable frame rates, VRR can help reduce screen tearing. However, this is the only element that could be considered beyond the minimum.

It must be made clear that the PUS8560 is not equipment 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 response time of the panel is not among the fastest. This model may be suitable at most for casual gamers who want to enjoy the Ambilight system.

In terms of features for gamers the TCL A400 Pro performs brilliantly. The TV has practically everything you can 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-generation consoles and a PC. Another plus is the presence of the Game Bar, a special 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 also adjust the appearance and behaviour of some settings to suit your preferences. This solution 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 connectors out of the four available, and one of them also serves as eARC. In practice this means that if someone wants to connect two next-generation consoles and a soundbar, they may run into some limitations. In that scenario you will have to either swap devices or use additional equipment, such as an AV receiver or a soundbar with HDMI inputs. Even so, it is hard not to rate the A400 Pro very highly as a TV for gamers. The gaming feature set here is truly powerful.
