Sharp GR8 vs LG QNED86A / QNED85A / QNED87A

Sharp GR8 boasts "very high brightness" at a level of 500 nits in its promotional materials. 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 somewhat sharper than in standard SDR, but it is difficult to speak of true juiciness and depth in bright elements. However, the coverage of the DCI-P3 color palette at 95% deserves praise. This is the result of applying an additional PFS coating, known from QLED technology. As a result, colors are vivid and have a pleasant, natural tint, which partially compensates for the deficiencies in brightness.

Against the backdrop of contrast and black, the brightness of the QNED86A and the overall HDR effect performs much better. This is a television that can reach around 700 nits in the best conditions, so in terms of brightness alone, there is nothing to be ashamed of. As a result, scenes with strong lights, explosions, flashes, or bright parts of the landscape look clear and can make an impression. Interestingly, even in more challenging moments with small, contrasting elements on the screen, the television handles their backlighting well, and the details are quite visible. The problem resurfaces when there are a lot of dark tones. The lack of effective local dimming causes black to virtually disappear, and instead, we get a gray glow spreading across the entire screen. This kills the sense of depth and makes the image look flat, as if it lacks a cinematic quality. In bright animations or colorful family films, this won't be an issue because colors and bright light dominate there. But in horrors or productions set in darkness, these limitations are very palpable. As a consolation, it’s worth mentioning that the QNED86A is actually a QLED television with a PFS LED filter, which gives it very good coverage of wide color gamuts. Both the DCI-P3 palette and the wider BT.2020 perform really solid here. This ensures that colors in HDR films are saturated, vibrant, and have the right depth – even if the black itself disappoints, the colors can save the viewing experience and make the image look attractive.

At the outset, it is worth noting that color reproduction tests are always conducted in the best factory picture mode. In the case of the Sharp GR8, this is the "Film" mode. As for the white balance, which is a characteristic that affects how we perceive colors on the screen, in SDR mode, the strong dominance of blue immediately stands out. This results in an unnatural cooling of the image—blue elements take on a purple hue, and skin tones acquire a pink glow, which we can see in the comparative photo from the movie STAR WARS. During the Color Checker test, it was clearly visible how the color samples deviated from the reference values, confirming significant errors in color reproduction. Gamma was not perfect either—it caused excessive brightening of the entire image, causing the scene to lose depth and proper tonal transitions.

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

In summary, the "Film" mode on the Sharp GR8 would require some adjustments to fully utilize the potential of this television. Fortunately, we addressed this and proceeded to calibration.

We primarily tested the QNED86A in Filmmaker mode, which is designed to provide the most accurate picture. Unfortunately, right out of the box, there were quite a few shortcomings. The most noticeable issue was the poorly adjusted white balance – there was a lack of blue, causing the overall image to lean slightly yellow, and at times, even orange. An even bigger problem turned out to be the way the television manages brightness. Due to its technical limitations – namely, local dimming that only works along the edges of the screen – the QNED86A tends to over-brighten entire scenes. This is where the flattening effect we mentioned earlier comes from. Instead of distinct depth and contrast, we get something akin to "boosted brightness," which can strain the eye over time.

Sharp GR8 is one of those televisions that really gains a second life after proper calibration. Both in HD and 4K content, the white balance performs very well, especially considering the price segment of this model. The image becomes much closer to what the director wanted to show – colors look natural, and skin tones acquire the appropriate depth and warmth. The brightness characteristics also leave a very positive impression. Both gamma and the EOTF curve show really solid values. Although minor imperfections can be noticed, they are subtle enough that it's hard to see them during everyday viewing. In summary, calibration makes the Sharp GR8 show its best side, offering an image that is not only pleasant to the eye but also faithfully conveys the creators' intentions.

What was saved in the QNED86A6A is undoubtedly the colors. After calibration, the white balance was set with great precision, resulting in deviations on the Colour Checker palette mostly not exceeding the threshold of visibility for the human eye. In other words – the colors finally looked natural, without strange yellow or orange tones that previously ruined the experience. Unfortunately, even the best calibration cannot bypass design limitations. The already mentioned very modest number of local dimming zones and their unfortunate placement made the analysis of the EOTF curve in films still show clear over-brightening of scenes. The image tended to flatten, lacking cinematic depth. Fortunately, this effect is not as noticeable in older productions or SDR content. There, calibration really does its job and allows taming the QNED in such a way that the image can be pleasing. However, the specifics of this design – especially the contrast issues – cannot be entirely overcome.

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

When it comes to image scaling, the Sharp GR8 performs significantly better here. The television is capable of giving the image a plastic, smooth characteristic, making even lower resolution content look quite good. Of course, with more demanding details, such as thin tree branches in the background, you can see slight jaggedness, but this is not something that would significantly affect viewing comfort.

If someone is worried about possible "steps" when connecting colors, there is a simple way in the QNED86A. Just turn on the feature called Smooth Gradation and set it to medium level. Then the TV really smooths out all those unwanted transitions – especially in older productions – and does it in such a way that the film grain doesn't disappear, nor do strange artifacts appear. In other words, you can use it without worry.

The upscaling itself also turns out quite well. Of course, there are no miracles here – with lower quality sources, you can observe characteristic jaggedness. Fortunately, there is a sharpness slider in the menu, and if someone prefers a more "softer" image, it can be quickly adjusted to their taste.

This is where the Sharp GR8 has the chance to stand out against the competition in its price segment. The TV is equipped with a 144 Hz refresh rate panel, which is an impressive result, especially if we plan to use it for dynamic content such as action movies, sports broadcasts, or video games. Additionally, the manufacturer has included a motion smoothing feature, commonly referred to as a "smoothener." The user has three levels of adjustment available, allowing them to tailor the effect to their own preferences – from subtle smoothing to more aggressive intervention in motion fluidity. This is a nice addition, especially for those who mainly watch movies and value smooth, cinematic sequences without annoying stuttering or frame drops.

The QNED86A is equipped with a 120 Hz refresh rate panel, so right from the start, it's safe to say that it's suitable for both sports and gaming. And indeed, this is true – the image looks smooth, and motion blur is not very noticeable. IPS panels have always had some issues with this, and you can sometimes notice slight blurring here as well, especially in very dynamic scenes, but it's not something that ruins watching a match or a fast-paced game. For movie and sports fans, LG has added the traditional TruMotion smoother. In the menu, we have two sliders – one for movies (De-Judder), the other for sports (De-Blur). The first adds missing frames and allows you to adjust the character of motion – from raw, cinematic to more fluid, "theatrical." The second enhances sharpness during dynamic actions, so it's worth turning it up a bit if you're watching a lot of sports.

If a television has a 144 Hz display 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 right connections to maximize the performance of modern consoles and PCs. It also features ALLM, which automatically switches the television to low-latency mode, and VRR, which prevents screen tearing even in more demanding moments. In practice, everything works as it should, and it is hard to find any faults. However, there are some shortcomings. It lacks support for HGiG, which is a feature that better adjusts HDR for games, as well as a Game Bar that makes it easier to quickly adjust settings without leaving the game. Despite these downsides, the Sharp GR8 is a really solid option for gamers.

In terms of gaming, the LG QNED86A6A is a complete tool. It features four HDMI 2.1 ports with full bandwidth of 48 Gb/s, which means that whether you connect a PlayStation 5, Xbox Series X, or a powerful PC – everything will work at full 4K 120 Hz with support for all features. This is a big plus, as some competitors still have only two such ports, which can be problematic with a larger number of devices. It also has VRR, or variable refresh rate, which eliminates screen tearing, and ALLM, which automatically activates game mode when the console is turned on. There’s also Dolby Vision Gaming and a proper implementation of the HGiG format, so titles supporting these formats look more vivid and detailed. Added to all of this is the Game Optimizer – a kind of control center for the gamer. From this level, you can view image parameters in real-time, quickly change modes, activate additional features, or adjust image settings to your preferences. The LG QNED86A6A essentially has everything one can expect from a modern gaming television.
