Philips PUS8500 vs TCL C6KS / C69KS / Q6CS

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.

And what about HDR? Here, the C6KS performs quite well and – as has become a recurring theme of this review – identically to the C6K model. The maximum brightness generated by this television is around 600 nits. In bright scenes, this translates to a really solid, cinematic effect, and generally, the video materials look good here. However, one must keep in mind the specifics of the dimming algorithm in this model. When very small, bright points (e.g., stars) appear against a dark background, the television can dim them quite significantly. The goal is simple: to eliminate blooming and maintain the best possible blacks. This is quite a reasonable compromise. Most viewers will definitely appreciate deep, "true black" more than additional micro-details, the display of which could cause the screen to appear greyed out. This is the nature of local dimming technology in this price range, and one must be aware of it. It is also worth noting that the TCL C69KS (C6KS) has an additional PFS coating, which is marketed under the slogan of QLED technology. Thanks to this, the colours are saturated and vibrant – our measurements showed that the coverage of a wide colour gamut reaches as much as 92% here.

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.

Unlike the more expensive C6K model, the tested C6KS does not have an option in the menu labelled as Filmmaker Mode. Is this a reason to cry? Absolutely not. Our tests have shown that in practice, in terms of colour reproduction, the lack of this specific label makes virtually no difference. The best available Film/Cinema mode here offers an almost identical picture characteristic to the aforementioned Filmmaker in the more expensive model. So we get a very similar image, just under a different name. Therefore, if you were wondering whether paying extra for the C6K gives you better colours – the answer is no, in both cases the base is the same and requires slight adjustments.

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.

Thanks to the white balance adjustment, the C69KS's tendency to distort colours has been effectively limited, resulting in a very good final effect. After calibration, we will no longer see excessive warming of scenes in SDR or overly cool tones in HDR. However, it is worth noting the brightness characteristics. In SDR content, it is hard to have any objections – the image looks very good, especially in older films, television programmes, or materials from YouTube. It is significantly more challenging to evaluate the television's performance in HDR. Analysis of the EOTF curve suggests correct behaviour, but its practical variant reveals certain limitations. The C69KS can overly brighten the smallest elements of the frame, while at other times, it can dim the entire scene. Thus, calibration brought clear benefits in terms of colour quality, but certain limitations resulting from the local dimming operation and the way it is controlled by the C69KS cannot be overlooked, as we also saw in the C6K test.

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).

The C69KS handles upscaling quite well. The tested 576p material looks surprisingly decent – a considerable amount of detail is retained, and the algorithm adds a slight "rounding" effect to sharp edges, making the image appear more cohesive. The performance in smoothing tonal transitions is less impressive. The television practically cannot improve them, leaving the image in a rather raw state. With older material, this can be quite tiring, as the lack of additional processing highlights any imperfections.

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.

C69KS offers a simplified motion enhancement panel in films, allowing the adjustment of effect intensity with a slider. This makes it easy to match fluidity to personal preferences. The ability to use higher refresh rates is also a plus – although the panel operates natively at 4K at 60 Hz, lowering the resolution to 1440p enables 120 and 144 Hz modes, both on consoles and PC. This sounds like great news, however, in practice, the image at these settings exhibits significant motion blur. The effect is so pronounced that the overall presentation appears merely average and loses its appeal for everyday use.

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.

If we overlook the smudging and lack of native 4K at 120 Hz, the C69KS impresses with how well it performs during gaming. We get everything one can expect from a gaming television: variable refresh rate (VRR), automatic switching to game mode (ALLM), Dolby Vision Gaming mode, and a well-functioning HGiG. The television can also operate at 120 and even 144 Hz at lower resolutions, allowing for smoother gameplay on a console or PC. Additionally, there is a clear Game Bar that lets you quickly glance at key settings while gaming. As a result — despite a few limitations — the C69KS can be a really successful screen for gamers.
