Sharp GR8 vs Samsung U8000F (IPS)

Sharp GR8 in its promotional materials boasts of "very high brightness" at a level of 500 nits. Unfortunately, our tests showed that reality is somewhat different – the average luminance we were able 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 sharper than in standard SDR, but it's hard to talk about true vibrancy and depth of bright elements here. However, the coverage of the DCI-P3 colour palette at 95% deserves praise. This is the result of applying an additional PFS coating, known from QLED technology. As a result, colours are vibrant and have a pleasant, natural tone, which partially compensates for the shortcomings in brightness.

Better doesn't mean good – and that's exactly how you can sum up the capabilities of the U8092F when it comes to displaying bright movie scenes in HDR mode. The brightness of the panel is just under 250 nits, which is definitely too low to enjoy any light effects. An interesting situation was observed during measurements of the fourth scene from the movie Sicario 2 – the television clearly dimmed the entire screen in an attempt to achieve better black levels (which still remain weak). One could even suggest that the device employs some form of "global dimming," but unfortunately – the effects are still very poor. To make matters worse, the television does not support a wide colour gamut – the coverage of the DCI-P3 space is around 80%, so don’t count on truly vibrant colours. The HDR image here looks more like slightly brightened SDR, and that’s the approach we would suggest you stick to when it comes to this television.

At the beginning, it's 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. When it comes to white balance, which affects how we perceive colours 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 appear to have a pink tint, which we can see in the comparative photo from the film STAR WARS. During the Color Checker test, it was clearly visible how the colour samples deviated from the standard values, confirming significant errors in colour reproduction. The gamma was also not ideal – it caused excessive brightening of the entire image, causing the scene to lose depth and proper tonal transitions.

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

To summarise, the “Film” mode in Sharp GR8 would require some adjustments in order to fully utilise the potential of this television. Fortunately, we took care of this and proceeded with calibration.

Samsung U8000F has been tested in the best possible built-in picture mode on the television, which is Filmmaker Mode. This mode should – at least in theory – provide a cinematic, reference image without unnecessary enhancements. For SDR content (mainly HD/SD), the television presented itself surprisingly well out of the box. White balance errors hovered around a value of 3, which is roughly on the edge of perceptibility. The only criticism could be directed at brightness management – the gamma chart showed a slight tendency to brighten or darken certain sections, but overall it performs quite well for this price segment.

Unfortunately, it looks much worse in HDR mode. Although the white balance was not terrible, the television had significant colour errors – particularly evident on the Color Checker chart, where almost every sample fell outside the target point. The image in HDR simply looks unnatural, and the colours can be shifted, muted, or too cool. This largely stems from the fact that U8000F does not support a wide colour gamut (DCI-P3). The television is physically unable to display correct colours in the HDR standard – and this is unfortunately felt in every more demanding material.

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 this model's price segment. The picture becomes significantly closer to what the director intended to show – colours appear natural, and skin tones gain the right depth and warmth. The brightness characteristics also leave a very positive impression. Both the gamma and the EOTF curve demonstrate really solid values. While slight imperfections can be noticed, they are subtle enough that it's difficult to see them during everyday viewing. In summary, calibration allows Sharp GR8 to show its best face, offering a picture that is not only pleasant to the eye but also faithfully conveys the creators' intentions.

Even though the U8000F already offered a fairly good picture in SDR straight out of the box, we managed to tweak it a bit more. We were able to remove a slight purple tint and adjust the gamma to a more reasonable level. However, the television still tends to over-brighten the smallest and brightest parts of the image – the gamma chart shows a characteristic "dip" that is hard to fully straighten out.

Unfortunately, the situation looks worse in HDR. It's difficult to talk about any significant improvement here – the television simply isn't designed for HDR content. We tried to adjust the picture in the advanced settings, but despite our efforts, the colour errors remained quite noticeable – a delta E above 7 is already significantly visible deviations. It's a bit unfortunate, but that's the charm of a budget build. In SDR, the U8000F performs reasonably, whereas HDR is simply not its league.

Sharp GR8 is equipped with a feature called "10-bit colour reproduction," 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 feature surprisingly smooths out things it shouldn’t - walls, shirts, or other flat surfaces look almost as if they have been ironed. In the test, we had to note that there is simply no actual impact on tonal transitions.

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

When it comes to how the Samsung U8000F handles lower quality materials, we must admit that Samsung has made progress compared to its predecessor from last year – the DU7192 model, which theoretically occupies the same place in the offering.

This year's model has been equipped with a function to improve the smoothness of tonal transitions, which has been implemented significantly better than last year. Yes, the TV still uses quite strong algorithms that can distort details or remove film grain, but even so – it can be confidently said that it operates effectively.

However, not everything has gone perfectly. The U8000F has noticeable issues with slight frame stuttering when watching very old content in very low resolution. If someone plans to play their old VHS tape, they must be aware that the picture may appear slightly "choppy".

This is where Sharp GR8 has the opportunity to stand out against the competition in its price segment. The television 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 films, sports broadcasts, or video games. Additionally, the manufacturer has included a motion smoothing feature, commonly known as a 'smoother'. The user has three levels of adjustment available, allowing them to tailor the effect to their personal preferences – from subtle smoothing to a more aggressive intervention in the fluidity of the image. It's a nice addition, particularly for those who mainly watch films and care about smooth, cinematic sequences without annoying judders or stuttering.

Samsung U8000F is equipped with a 60 Hz panel, so right from the start, it's clear that we shouldn't expect miracles. This is simply the standard in this class – sufficient for everyday viewing, but without any fireworks.

The television offers one motion smoothing slider – a feature called “Motion Blur Reduction”, which allows us to adjust the smoothness of the image in movies. Higher settings provide a more “theatrical” and smoothed effect, while lower ones maintain the original character of the film with a slight 24p effect. An interesting feature is “Clear Motion LED”, or BFI mode – which inserts black frames between the image frames to enhance motion clarity. However, in practice, the screen flickers significantly when it's activated, and it's better viewed as an experiment rather than something that truly enhances gaming comfort.

If the television has a 144 Hz panel and two full HDMI 2.1 ports, it’s clear it was designed with gamers in mind. The Sharp GR8 offers exactly that – high refresh rates and the right connections to get the most out of modern consoles and PCs. It also features ALLM, which automatically switches the TV to low latency mode, and VRR, ensuring the picture doesn’t stutter even in more demanding moments. In practice, everything works as it should, and it's difficult to find fault. However, it’s not without its shortcomings. There’s a lack of support for HGiG, which 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 a really solid option for gamers.

Samsung U8000F offers a basic set of features for gamers, which may still be sufficient for less demanding users. It has an automatic game mode – when a game is launched on the console, the TV automatically switches to low latency mode, which significantly improves response time. It also includes a VRR function, or variable refresh rate, which works within the range of 48 to 60 Hz. This means that both Xbox and PS5 won't produce the "tearing" effect – as long as we stay within this range.

And unfortunately, that's about it for the advantages. Additional features like Game Bar or higher refresh rates are reserved for higher models of Samsung’s 2025 line. In theory, the TV also supports the HGiG function, which should adjust the HDR image to the intentions of game developers. Unfortunately – although this function appears in brochures and store materials – its setup on the Xbox console turned out to be... impossible in practice.
