Samsung DU8002 (IPS) vs SHARP JP7765E

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

So how does the brightness of the Sharp JP7 perform in the most demanding titles? Honestly, we were quite surprised at first. The TV is able to achieve over 1000 nits of brightness, which is an outstanding and rare result for a device costing just under 2000 zł (for 55 inches). Watching bright, full-screen scenes, you can get the impression that you are dealing with really good equipment. But unfortunately, we have to return to the issue we mentioned earlier, which is local dimming management. When small, bright spots appear on a dark background (like in test scenes from the films Life of Pi or Sicario 2), it’s clear how poorly the JP7 handles these zones. The TV dims them almost to the maximum, crushing the whole HDR effect, which at such moments resembles a flat SDR image (less than 200 nits). This instability means that in demanding, contrast-rich films, the image on the JP7 unfortunately loses its appeal.

As a consolation, it's worth noting that the panel has the potential to display colours well. A PFS (phosphor) filter has been employed here, which allows the coverage of the DCI-P3 colour gamut to reach a solid 94%. The manufacturer calls its product a “QLED,” even though it technologically relies mainly on the aforementioned PFS filter. Considering the recent market battles between manufacturers over what can and cannot be called QLED, we leave the issue of the correctness of this terminology to your judgement. However, it remains a fact that the potential for reproducing saturated colours in this panel is simply good.

DU8002 offers a Filmmaker mode, which is supposed to provide authentic image reproduction in line with the creators' intentions. Unfortunately, despite its promising name, the effects are far from ideal. The white balance in this mode shows significant drops in blue colour, leading to a noticeable yellowing of the image, as seen in our comparison photo. Colour Checker tests confirm these errors. Regarding 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 materials shows significant increases above the reference line, leading to overly bright small light elements. As a result, the Filmmaker mode in DU8002 does not meet expectations and instead of providing high quality, presents an image full of tonal and colour inaccuracies.

When it comes to colours straight out of the box, the Sharp JP7 was tested in the Film mode, which traditionally offers the most cohesive image compared to the yellowed “Eco” mode or the glaring blue of the “Dynamic” mode. Although this is the best choice among the available settings, the results still fall short of ideal. The white balance clearly lacked red and blue components, causing many scenes to take on an unnatural, greenish hue. Another issue was the gamma – in full-screen scenes, the TV produced excessively bright images, completely robbing it of its cinematic character. All of this resulted in colour reproduction errors, especially in shades of grey, which exceeded the Delta E 10 value. To remind you: errors above 2-3 are already noticeable to the human eye, so here we are dealing with a significant distortion of reality.

In HDR mode, the situation is reversed, but not in a better way. Here, the white balance is dominated by blue, giving the image an unnatural, almost “store-like” sharpness, reminiscent of aggressive demonstration modes. Moreover, the measurements of the EOTF curve emphasise the store-like nature of the image. The graph clearly shows that the TV generates images that are significantly brighter than the standards predict, resulting in an artificially boosted and unrealistic final effect. The Sharp JP7 is evidently trying to appear stronger than it actually is, but it does so at the expense of fidelity to the original content.

Samsung is one of those companies that offers advanced tools to enhance picture quality in its televisions, including a 20-point white balance adjustment. Even in the budget model DU8002, after proper 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 levels of 2–1.5, which indicates the significant capabilities of this television in colour 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 significantly adjusted, meaning the image is not overly brightened and appears more natural. What about the EOTF curve? At first glance, it seems fine, but upon closer inspection, especially in film tests, it's clear that the television struggles due to its low-contrast panel. And the EOTF drops below the reference line. Nevertheless, the DU8002 is an example of a budget model where investing in calibration is worthwhile. Although construction flaws, such as the type of backlighting, cannot be completely eliminated, colour accuracy is surprisingly good, especially considering its price.

We subjected the JP7 to our standard calibration procedure and honestly... the television gained a second life thanks to it, especially with SDR content (YouTube, traditional television, series, or older films). With our precise adjustments to the white balance and stabilisation of the gamma, colour errors dropped to a value of below 3. This is a level at which the human eye struggles to perceive discrepancies. In this scenario, the Sharp JP7 delivers an image with truly excellent colour accuracy, which is a significant advantage in this price range. However, the HDR content turned out to be much more problematic. Here, despite our efforts and interventions in the settings, the television simply refused to cooperate. In the JP7 menu, we won’t find any option to effectively control how brightness is managed (EOTF). Although a significant portion of the colour errors has been reduced, the image still remained unnaturally oversaturated. It’s a bit disappointing because the potential of the mini-LED backlit panel is great, but the software presents a clear barrier.

The conclusion is simple: when watching less demanding content (SDR) on the JP7, you can expect an image that is more than satisfactory, but in HDR you will have to accept a certain degree of "artificiality" that cannot be bypassed even with professional equipment.

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

Nonetheless, the television handles upscaling, or digital image processing, exceptionally well. The test pattern with the model looked really good – the image isn't 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.

When it comes to lower quality materials and how Sharp JP7 handles them, the situation is ambiguous. Let's start with the upscaling itself – here we have no major objections. The process of scaling the image to a higher resolution is correct; the picture remains readable and clear, without the overscan effect, which means no cropped edges. Of course, it's not at the level of top models and at times you can notice slight tearing on the edges, but in this price range, the effect is fully acceptable.

However, the actual digital image processing performs much worse, as aside from the scaling, it practically doesn’t exist. In the JP7 menu, we won’t find any options that would effectively smooth out unwanted tonal transitions or reduce noise in the image. As a result, the signal hits the panel in a very raw form, which with heavily compressed materials (e.g., from YouTube) results in noticeable posterisation. Either this is a programming error or a very strange design decision, because in earlier Sharp models this function was available and, more importantly, worked with noticeable effect. Here, we are stuck with what the source delivers, without any digital support from the image processor.

The 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 fluid enhancer, smoothing out movement and giving scenes a more fluid appearance, which is useful for movie sessions. In the context of gaming, this model is likely only suitable for occasional entertainment.

The motion fluidity on the Sharp JP7 is quite average, and the reason is simple: the TV uses a 60Hz panel. This immediately makes it hard to recommend for watching sports or serious gaming, where higher refresh rates are already the standard. The only real plus is the presence of a motion smoother, which we can control in films with a slider called De-judder. Lower settings give a more raw, “cinematic” (framey) image, while higher ones add artificial fluidity. We suggest setting it somewhere in the middle of the scale, around 3-5 – this is the best compromise to avoid the soap opera effect while also getting rid of the annoying image skipping. Interestingly, in the menu, we also find a slider for "motion blur reduction," which usually indicates the presence of a 120Hz panel. However, in the case of the JP7, it doesn’t actually enhance the image and serves more as a dummy – it looks good in the settings, but technically it shouldn’t work on this panel.

DU8002 is a television that is mainly suited for casual gamers. The 60 Hz panel won't provide the highest motion fluidity, so in dynamic games, you might miss that extra smoothness of the image. On the plus side, it has ALLM and HGiG functions, which automatically adjust the picture settings for HDR games, enhancing the gaming experience. Unfortunately, the TV only comes with HDMI 2.0 ports, so we have to forget about more advanced features like VRR or support for 4K at 120 Hz. Choosing this equipment means we will have to make do without a full set of gaming features.

As we mentioned earlier, the 60Hz panel is not a feature that will attract gamers to the Sharp JP7. Perhaps for the casual gamer, whose console still generates most titles at 60 frames per second, there might be something interesting? When it comes to specific additions, we find here:

• ALLM mode: Automatically switches the TV to low latency game mode (input lag).

• Player menu: Which is hard to call a fully-fledged “Game Bar,” as the functionality is minimal. Aside from enabling ALLM, there’s only a dedicator for gaming which we advise against as it introduces very noticeable artifacts and spoils responsiveness.

• Dolby Vision Gaming: For Microsoft's consoles.

Unfortunately, the list of shortcomings is much longer and more painful than the positives. The biggest disappointment is the lack of support for 120Hz, even when reducing the resolution to Full HD. The presence of 120Hz would allow for performance modes to be activated in many games on the PS5 or Xbox Series X. Another shortcoming is the VRR, which means that during frame drops, we are susceptible to screen tearing. Very problematic is also the lack of proper implementation of the HGiG standard. This results in the fact that during HDR calibration in the console menu, it is very easy to "overshoot" the brightness settings. As a result, instead of clear details in the highlights, we end up with an unnaturally oversaturated image with cut-off details. The Sharp JP7 is a proposal only for those who game very occasionally.
