Sharp GR8 vs Philips PUS8500

Sharp GR8 in its promotional materials boasts of "very high brightness" at a level of 500 nits. Unfortunately, our tests showed that the reality is somewhat different – the average luminance value we managed to achieve was around 360 nits. This is rather an average result, especially in the context of the manufacturer's claims. Such brightness does not allow for a full enjoyment of HDR effects. The image is a bit more defined than in standard SDR, but it is difficult to speak of true richness and depth in bright elements here. However, praise is due for the DCI-P3 colour gamut coverage at a level of 95%. This is a result of the application of an additional PFS layer, known from QLED technology. As a result, the colours are vivid and have a pleasant, natural tone, which somewhat compensates for the deficiencies in brightness.

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.

At the outset, it is worth noting that colour reproduction tests are always conducted in the best factory picture mode. In the case of Sharp GR8, this is the “Film” mode. As for white balance, which affects how we perceive colours on the screen, in SDR mode, there is an immediate noticeable dominance of blue. This results in an unnatural cooling of the image – blue elements take on a purple hue, and skin tones acquire a pinkish glow, as we can see in the comparative photo from the film STAR WARS. During the Color Checker test, it was clear that the colour samples deviated from the reference values, confirming considerable errors in colour reproduction. The gamma was also not ideal – it caused excessive brightness throughout the entire image, resulting in a lack of depth and appropriate tonal transitions in the scene.

In 4K HDR mode, the situation looks significantly better. The dominance of blue is much less noticeable, although there are minor issues with the combination of red and blue. This causes some shades to appear somewhat unnatural. The EOTF curve, responsible for the brightness of the image in 4K HDR content, revealed another problem – the television tends to excessively dim the image across the entire surface of the screen.

In summary, the “Film” mode in Sharp GR8 would require a few adjustments to fully utilise the potential of this television. Fortunately, we took care of that and proceeded with calibration.

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.

Sharp GR8 is one of those televisions that truly gains a second life after proper calibration. Both in HD and 4K content, the white balance performs very well, especially when considering the price segment of this model. The image becomes much more aligned with what the director intended to show – colours look natural, and skin tones acquire the appropriate depth and warmth. The brightness characteristics also make a very positive impression. Both gamma and the EOTF curve display really solid values. While minor imperfections can be noticed, they are subtle enough that they are difficult to detect during everyday viewing. In summary, calibration allows the Sharp GR8 to showcase its best features, offering an image that is not only pleasant to the eye but also faithfully reflects the creators' intentions.

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.

Sharp GR8 has been equipped with the "10-bit colour reproduction" feature, which theoretically should improve the smoothness of tonal transitions. In practice… well, the effect is surprising, but not in a particularly positive way. Even at the highest settings, it is difficult to notice any impact on the actual tonal transitions. Instead, the feature surprisingly smooths out what it shouldn't – walls, shirts, or other flat surfaces look almost like they have been freshly ironed. In the test, we had to note that there is simply no actual impact on tonal transitions.

As for image scaling, here Sharp GR8 performs significantly better. The television can give the image a plastic, smooth characteristic, meaning even lower resolution content looks quite good. Of course, with more demanding details, such as thin tree branches in the background, one can notice slight jaggedness, but it is not something that would significantly affect viewing comfort.

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).

This is where Sharp GR8 has the chance to stand out from the competition in its price segment. The television is equipped with a 144 Hz refresh rate panel, which is an impressive achievement, especially if we plan to use it for dynamic content such as action films, sports broadcasts, or video games. Additionally, the manufacturer has ensured the presence of motion smoothing technology, commonly referred to as a “smoothness enhancer.” The user has three levels of adjustment at their disposal, allowing them to tailor the effect to their own preferences – from subtle smoothing to a more aggressive intervention in the smoothness of the image. This is a nice addition, particularly for those who mainly watch films and care about smooth, cinematic sequences without irritating stutters or frame drops.

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.

If the television has a 144 Hz panel and two full HDMI 2.1 ports, it is clear that it has been designed with gamers in mind. The Sharp GR8 offers exactly that – high refresh rates and the appropriate connections that will allow you to get the most out of modern consoles and PCs. It also features ALLM, which automatically switches the television to low latency mode, and VRR, which ensures the image does not stutter even during more demanding moments. In practice, everything works as it should, and it is hard to find fault with anything. However, there are some shortcomings. It lacks support for HGiG, which is a feature that better adjusts HDR for games, as well as Game Bar, which makes it easier to quickly adjust settings without leaving the game. Despite these drawbacks, the Sharp GR8 is truly a solid option for gamers.

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.
