Philips PUS8500 vs TCL A400 PRO

When it comes to HDR performance on the PUS8560, it's safe to say that it's rather average. The brightness of the panel is around 350 nits, so we consider this to be the absolute minimum for watching content in this format. However, it’s not a result that will impress viewers looking for the best possible picture.

On the plus side, it's worth noting that the PUS8500 series – including the PUS8560/12 tested here – is marketed as a QLED television. And indeed, we can expect a wider colour gamut here. This model is equipped with an additional filter (PFS), and the DCI-P3 coverage of around 90% should suffice for most users. This filter operates very similarly to quantum dots. As a result, colours are quite well-saturated. It's not an outstanding result, but it's entirely sufficient for watching movies 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 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 television on the best available factory settings, that 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 distinct tendency to pinkness, caused by an excess of red and blue in the white balance. Another issue turned out to be excessive brightness of the image, as confirmed by both the gamma graph and the EOTF curve. This characteristic was responsible for the loss of detail and washed-out colours in more challenging HDR scenes we mentioned earlier. All of this led to quite significant colour reproduction errors – in extreme cases, the delta E value exceeded 7, while the threshold for visibility of errors for the human eye is about 3. This situation can be improved through calibration, and you can read about its effects 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.

The Dutch manufacturer offers quite a large dose 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 cease to appear overly pinkish. The brightness characteristics were also partially equalised, of course within the limits that the television itself allows. The picture is no longer so excessively brightened, and the overall reception after calibration is definitely better than in the factory settings of the Filmmaker mode.

You could only nitpick about the characteristics of the EOTF curve, which still indicates that the image tends to brighten HDR content. Despite our efforts, the darkest parts of the scenes can still be too bright, and the brightest ones do not always reach their full contrast potential. However, it must be clearly stated that we are dealing with a typically budget-oriented design – one cannot expect reference-quality rendering 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 can expect from a well-configured movie mode. However, there are certain limitations that cannot be overcome.

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.

Philips PUS8560 offers a deinterlacing function, hidden under the name “distortion reduction”. And while it indeed serves its purpose, smoothing out problematic tonal transitions, it operates a bit too broadly. In practice, it affects not just colourful gradients but also softens faces, clothing textures, and furniture surfaces. This undermines the authenticity of the image – especially in films where natural texture is of great importance. However, if someone is looking for smoothing at any cost, it’s best to set this option to “Low”. For cinema image enthusiasts – we definitely do not recommend it.

On the plus side, the quality of scaling older materials is worth noting – the PUS8560 model handles them surprisingly well. The image retains a natural softness without artificially boosted sharpness. It’s also worth mentioning that the TV correctly displays very low-resolution content, avoiding issues with image cropping (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’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 Philips PUS8560 is a television equipped with a 60 Hz refresh rate panel, which already limits its capabilities for displaying dynamic content right from the start. Watching sports or playing on a console is not one of the more enjoyable experiences. The situation is further worsened by the absence of any option to improve film fluidity. In the menu, you won’t find settings that would allow for the activation of motion smoothing or even a slight motion blur for films recorded at 24 frames per second. You can imagine the effect. The image can appear choppy, 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 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.

Although the Philips PUS8560 is not designed with gamers in mind, the manufacturer has equipped it with a few features that may prove useful when connecting a console. Onboard, we find automatic switching to game mode (ALLM), as well as a simple connection status information bar – the so-called Game Bar. It doesn't make a particularly 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. This is not a wide range, but for less demanding games or titles with unstable frame rates, VRR can help reduce the tearing effect. However, this is the only element that can be considered beyond the minimum.

It must be clearly stated 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 panel's response time is not among the fastest. This model may at best suit people who play occasionally and want to enjoy the Ambilight system.

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.
