Samsung DU8002 (IPS) vs Sharp GR8

The HDR effect on the DU8002 television leaves much to be desired. A brightness level of 300 nits cannot provide a true high dynamic range experience, which makes the viewed content resemble more of a standard SDR than impressive HDR. Scenes that should dazzle with brilliance and detail appear muted and lacking in depth. Nevertheless, the television deserves praise for its high coverage of the DCI-P3 colour gamut at 92%. This means that colours are vivid and saturated, which may satisfy viewers who prefer rich tones, even if the HDR effect does not fully meet expectations.

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.

The DU8002 offers a Filmmaker mode, which is intended to provide an authentic image reproduction in line with the creators' vision. Unfortunately, despite the promising name, the results are far from ideal. The white balance in this mode shows significant drops in blue, leading to a noticeable yellowing of the image, as seen 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 issue 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 the DU8002 does not meet expectations and instead of offering high quality, presents an image full of tonal and colour inaccuracies.

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.

Samsung is one of those companies that offers advanced tools for improving picture quality in its televisions, including a 20-point white balance adjustment. Even in the budget model DU8002, with the right adjustments, surprisingly good results can be achieved. The white balance, especially for HD content, is really good – tests on the Colour Checker palette confirm accuracy levels of 2–1.5, which speaks to this television's considerable capabilities in colour reproduction. In 4K content, although not as perfect as in lower quality materials, the overall picture looks significantly better.

The gamma brightness has also been heavily adjusted, meaning the picture is not overly bright and looks more natural. What about the EOTF curve? At first glance, it seems fine, but upon closer inspection, especially in film tests, it is clear that the television, due to its low contrast matrix, struggles. The EOTF also drops below the reference line. Nevertheless, the DU8002 is an example of a budget model where calibration is worth investing in. Although construction flaws, such as the type of backlighting, cannot be completely eliminated, colour accuracy is surprisingly good, especially given its price.

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.

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

Nevertheless, the television performs excellently with upscaling, or digital image processing. The test pattern with the model looked really good – the image is not excessively jagged, and the overall presentation is decent and pleasant to the eye. This is definitely good news for those planning to watch traditional television on this model.

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.

The DU8002 with a 60 Hz panel is a television that performs better for watching films than for intense gaming. The motion smoothing feature acts as a fluidizer, smoothing out movement and giving scenes a more fluid appearance, which is helpful for movie screenings. In the context of gaming, this model is more suited for casual entertainment.

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.

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

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.
