Samsung DU8002 (IPS) vs Sharp GR8

The HDR effect in the DU8002 television leaves much to be desired. A brightness level of 300 nits is not able to provide a true high dynamic range experience, making the content viewed resemble more of a standard SDR than impressive HDR. Scenes that should dazzle with brightness and detail appear muted and lacking in depth. Nevertheless, the television deserves praise for its high coverage of the DCI-P3 color palette at 92%. As a result, the colors are vivid and saturated, which may satisfy viewers who prefer rich hues, even if the HDR effect does not fully meet expectations.

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.

DU8002 offers a Filmmaker mode, which is supposed to provide authentic image reproduction in line with the creators' intentions. Unfortunately, despite the promising name, the results are far from ideal. The white balance in this mode shows significant drops in blue color, leading to a noticeable yellowing of the image, which can be seen, for example, in our comparison photo. Colour Checker tests confirm these errors. As for brightness, the gamma characteristic is too low compared to the reference line of 2.4, resulting in excessive screen brightness. A similar problem occurs with 4K content – the EOTF responsible for brightness in 4K material shows significant increases above the reference line, leading to excessively bright small light elements. As a result, the Filmmaker mode in DU8002 does not meet expectations and instead of offering high quality, presents an image full of tonal and color inaccuracies.

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.

Samsung is one of those companies that offers advanced tools for improving image quality in its televisions, including a 20-point white balance adjustment. Even with the budget model DU8002, with the right adjustments, surprisingly good results can be achieved. The white balance, especially for HD content, performs really well - tests on the Colour Checker palette confirm accuracy at the level of 2–1.5, which demonstrates the significant capabilities of this television in color reproduction. In 4K content, although not as perfect as in lower quality material, the overall picture looks much better.

The gamma brightness has also been heavily adjusted, ensuring that the image is not overly brightened and looks more natural. What about the EOTF curve? At first glance, it seems fine, but upon closer inspection, especially in film tests, it becomes apparent that the television struggles due to its low contrast panel. The EOTF drops below the reference line. Nevertheless, the DU8002 is an example of a budget model where investing in calibration is worthwhile. Although structural flaws, such as the type of backlighting, cannot be completely eliminated, color accuracy is surprisingly good, especially considering its price.

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.

Smoothing tonal transitions on the DU8002 television leaves mixed feelings. Although the menu offers an option for smoothing tonal transitions, in practice it yields no results and can even generate unwanted side effects.

Nevertheless, the television handles upscaling, or digital image processing, excellently. The test chart featuring a model looked really good – the image is not overly jagged, and the overall presentation is decent and pleasing to the eye. This is definitely good news for those planning to watch traditional television on this model.

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.

DU8002 with a 60 Hz panel is a television that performs better for watching movies than for intense gaming. The motion smoothing feature acts as a fluidizer, smoothing out motion and giving scenes a more fluid appearance, which is useful for movie screenings. In the context of gaming, this model will rather be suitable only for occasional entertainment.

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.

DU8002 is a television that will mainly serve as equipment for casual gamers. The 60 Hz panel does not provide the highest motion fluidity, so in dynamic games there may be a lack of that extra smoothness of the image. On the positive side, it features ALLM and HGiG functions, which automatically adjust image settings for HDR games, enhancing the gaming experience. Unfortunately, the television is equipped only with HDMI 2.0 ports, so we have to forget about more advanced features like VRR or support for 4K at 120 Hz. When choosing this equipment, we will have to make do if we expect a full set of gaming features.

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.
