Sharp GR8 vs Sony BRAVIA 5 (XR5)

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.

Looking at similar results in terms of blackness and contrast, we expected equally stable performance as last year's model when it came to HDR content. Unfortunately – and this needs to be said outright – there has been a regression here that is hard to overlook. The paradox is that the peak brightness of the Bravia 5 is impressive: in our synthetic tests, the television achieved around 1000 nits in HDR. Sounds great, right? The problem is that this power does not always translate effectively to all film scenes. When small, point-like elements appear on the screen, something that had usually been polished with surgical precision in Sony's case is this time noticeably lacking. The algorithms attempt to maintain deep black around small objects, but the side effect is that details can be dimmed to such an extent that they become barely visible. Just consider the example of the film Sicario 2 – in some scenes there, small light sources practically disappeared, as if someone had covered them with dark film.

Of course, not everything looks so dramatic. In simpler, brighter scenes, where the image is filled with more light, the Bravia 5 shows that it can shine: literally and figuratively. Then the television achieves values in the range of 600–800 nits, which we saw both in synthetic tests and during film screenings. The impression is really positive; the brightness adds dynamism, and the colours appear vibrant and fresh. However, there remains a certain dissonance. We feel a slight confusion because evidently something has gone in a direction it shouldn’t have. Technological progress – more zones, greater backlighting power – has not been supported by the well-crafted image management that we usually associate with Sony. Fortunately, there are elements that have not been worsened and are, in fact, at a very high level. We are talking about colour reproduction. Thanks to the application of the PFS filter, the colour palette coverage is excellent – around 97% DCI-P3 and 75% BT.2020. These are values that allow for truly broad colour reproduction, giving films a sense of naturalness and cinematic quality.

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.

Sony Bravia 5 was of course tested in the best possible mode, which is the Cinema mode. Right out of the box, it provides the most natural colours, definitely better than anything offered by the "eco" or "dynamic" modes, which are more suited for a showroom display than for a living room. However, the Cinema mode alone does not mean we can always expect cinematic picture quality. With SDR content, we had virtually no major complaints – the slightly warmed white balance gave the scenes a somewhat golden tone, but it was nothing that was visually jarring. However, the problem arose with HDR material. Here, the colour reproduction simply looked poor. The white balance was heavily skewed – with an excess of blue and a clear lack of red. At times, it resembled the store's "super vibrant image" mode, where everything is overexposed and artificially boosted.

This situation also made brightness management seem overly aggressive. The EOTF graph clearly showed that the television had problems with overexposing many scenes right out of the box. And while we know what Sony televisions are usually capable of, it was difficult to remain indifferent here – thus we quickly decided to go for calibration.

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.

After calibration, the situation changed dramatically. We managed to adjust the white balance so that entire scenes began to look more natural, and the image gained cohesion and elegance. In HDR, we finally got rid of that unwanted clipping effect that had previously marred some shots. Suddenly, it turned out that the Bravia 5 can extract significantly more from films than the “out of the box” impression suggested. Indeed, if we look at the graphs and compare them with the patterns, we can see that the beginning of the EOTF curve slightly deviates from the reference line. However, this is not so much a calibration error as it is a natural limitation of Mini-LED technology, which cannot be bypassed. Sony, instead of clinging to perfect black, prefers to prioritise the visibility of details – and in practice, it's hard to disagree with that. We would rather see the texture of the material on the screen than a pitch-black blob where all nuances are lost.

The calibration itself was truly beneficial. After about an hour spent on the settings, we felt that the image resembled that from the best cinema halls – of course on a home scale, but with the same sense of quality and refinement. And in such moments, we remember why we like Sony televisions: because when we fine-tune them, they can reward us with an image that captivates for long hours.

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.

Bravia 5 carries within it the genes of Sony, which have remained untouched – and thank goodness for that, because we are talking about absolutely remarkable digital image processing. It is no coincidence that for years it has been believed that it is televisions of this brand that set the standard for how a screen should handle lower quality materials. If someone still watches classic television, old films or YouTube in lower resolutions, here they get equipment that can transform such content into an unexpectedly pleasant experience. On board, we find several tools worth activating. The first of these is "digital noise reduction". Set to a medium level, it works perfectly – smoothing tonal transitions, which usually cause the most trouble in low-quality materials, while not introducing any artificial artifacts. Importantly, it also does not remove the filmic character, meaning the natural grain that is intentionally present in many productions. Another advantage of the Bravia 5 is the upscaling capabilities of the XR processor. The image displayed after scaling is soft, yet at the same time sharp and clear. The contours of characters are clearly visible, while backgrounds retain their structure without excessive artificial sharpening. It’s hard to find a better television for watching lower quality materials – Bravia 5 only confirms why Sony is regarded as a benchmark in this field.

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.

Bravia 5 received a 120 Hz panel, which in itself sounds like an invitation to watch sports, fast matches, or spectacular action films. However, the real magic begins when MotionFlow – Sony's proprietary smoothness technology – comes into play. Thanks to it, we can adjust the character of the image to our own preferences. The "smoothness" slider allows you to transition from a cinematic feel with a slight "jitter" of the film frame to a nearly theatrical fluidity, where every ball in the match glides across the screen as if on a string. The higher the value, the smoother and more fluid it is; the lower it is, the more cinematic and natural it feels. In the options, we will also find an additional setting that Sony has called "clarity". This is nothing more than the BFI function (i.e., inserting black frames), which is meant to improve motion sharpness. It sounds great in theory, but in practice, one must use it with great caution. Why? Because all higher settings cause brightness drops of up to half, and in some cases, contour doubling also appears. Therefore, if we wish to use it, we recommend the lowest possible level – "1" out of the available ten. This way, we gain a bit better motion clarity without risking a loss of half the image brightness.

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.

In the Bravia 5, there is a significant improvement compared to the X90L model from two years ago. The television offers literally everything its predecessor had, but this time the issues that could frustrate gamers have been fixed. The problems with setting variable refresh rate (VRR) have disappeared, and there are no longer any issues with configuring HDR content in HGiG mode. In short: we get hardware that simply works as it should, without any fuss. Therefore, the Bravia 5 has everything you could expect from a modern gaming television – and it can be reasonably advertised with the slogan “ready for PS5.” This is a statement we couldn't make about the X90L model. Well done, Sony!

It’s just a shame that this relatively high-priced model lacks a full set of four HDMI 2.1 ports. In everyday use, this won’t be a problem for most people, but if someone has a console, soundbar, and additional equipment hooked up via HDMI, at some point there will be a need to choose or juggle the cables.
