Samsung QN90F / QN92F vs SHARP JP7765E

The Samsung QN90F can truly shine with brightness. In our measurements, it achieved over 2200 nits, which directly translates to the viewing experience. In practice, this means that when a film features a very bright scene – for example, a sunrise in The Meg – the screen looks as if it is actually lit by natural light. This is not just a number from a chart, but a real sense of image intensity! However, the television may not always deliver this full power. With smaller details like reflections or lamps, brightness drops to 500–700 nits. This is a deliberate decision by the algorithms – it allows for better control of the contrast between large and small elements, preventing the image from losing balance. Importantly, this is still a huge improvement compared to last year's QN90D, where similar details were often almost invisible, shining at just 200 nits. Here, the HDR effect is much more consistent and credible. The only downside is the colours. The DCI-P3 coverage has stalled at 91%, which in this price bracket can be considered a rather average result.

So how does the brightness of the Sharp JP7 fare in the most demanding titles? Honestly, at first, we were quite surprised. The television is capable of achieving over 1000 nits of brightness, which is an outstanding and rare result for a device costing just under 2000 PLN (for 55 inches). Watching bright, full-screen scenes, one might feel they are dealing with really good equipment. Unfortunately, though, we have to return to the problem we mentioned earlier regarding local dimming management. When small bright areas appear on a dark background (as in the test scenes from the films Life of Pi or Sicario 2), it is evident how poorly the JP7 handles zones. The television dims them almost to the maximum, crushing the entire HDR effect, which in such moments resembles a flat SDR image (less than 200 nits). This instability means that in demanding, contrast-heavy films, the image on the JP7 unfortunately loses its appeal.

As a consolation, it is worth noting that the panel has the potential for good colour display. It features a PFS (phosphor) filter, which allows for a solid 94% coverage of the DCI-P3 palette. The manufacturer calls its product a “QLED,” even though it is primarily based on the aforementioned PFS filter. Given the recent market battles of manufacturers over what may or may not be called QLED, we leave the question of the correctness of this naming to your assessment. However, it remains a fact that the potential for reproducing saturated colours in this panel is simply good.

The colour reproduction of the QN90F was tested in Filmmaker mode and, as is often the case with Samsung televisions, this mode proves to be the best starting point straight out of the box. However, this does not mean that the image is free from flaws. The white balance in both SDR and HDR content was surprisingly good – the colours did not drift in any direction and even in its factory settings, it looked solid. A problem arose with the gamma curves and EOTF, which dictate how the television manages brightness. Here, the QN90F significantly brightened the entire image, causing blacks and colours to lose their intensity, and the overall effect resembled that of an applied milky filter. Fortunately, Samsung, unlike many competitors in the miniLED world, provides the user with plenty of tools to control the settings that we do not find with other manufacturers, such as Chinese producers. Therefore, we decided to see if we could squeeze the full potential out of the QN90F because we know that such a high-end series is capable of much more.

When it comes to out-of-the-box colours, the Sharp JP7 was tested in Film mode, which traditionally offers the most consistent 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 are still far from ideal. The white balance clearly lacked red and blue components, causing many scenes to take on an unnatural greenish tint. Another issue was the gamma – during full-screen scenes, the television provides excessive brightness, which completely diminishes its cinematic character. All of this resulted in colour reproduction errors, especially in shades of grey, which exceeded a value of Delta E 10. For reference: errors above 2-3 are already visible to the human eye, so we are dealing with a significant distortion of reality here.

In HDR mode, the situation is reversed, but not any better. Here, the blue colour dominates the white balance, which gives the image an unnatural, almost “retail” sharpness, reminiscent of aggressive demonstration modes. Furthermore, measurements of the EOTF curve emphasise the retail character of the image. The graph clearly shows that the television generates an image 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 cost of fidelity to the content.

After our adjustment of the settings, the QN90F displayed what it is truly capable of – and it must be admitted that this is one of the best images we have seen on a miniLED screen this year. As we mentioned earlier, the white balance was not a major issue even in its factory state, but only after gamma calibration did it manage to get close to reference values. The same is true for HDR content, where the EOTF curve post-adjustment presents mature and cohesive results. Indeed, in some films, it is noticeable that the smallest elements of the image are slightly brightened, and with a limited number of dimming zones, there is still a risk of halo effect. However, it should be remembered that such phenomena are characteristic of all miniLED televisions, and it is difficult to expect miracles even from the QN90F. The most important thing is that after calibration, the television delivers an image that, in terms of representing the director's vision, confidently competes with many OLED screens available on the market.

We subjected the JP7 to our standard calibration procedure and really... the television gained a new lease of life thanks to it, particularly with SDR content (YouTube, classic television, series, or older films). As a result of our precise adjustment of the white balance and stabilisation of the gamma, colour errors fell to a value of below 3. This is a level at which the human eye has difficulty detecting distortions. In this scenario, the Sharp JP7 delivers an image with truly excellent colour precision, which is a significant advantage in this price class. However, content with HDR turned out to be much more problematic. Here, despite our efforts and interventions in the settings, the television simply would not cooperate. In the JP7 menu, we don't find any option that would allow for real control over brightness management (EOTF). Although a significant portion of the colour errors was reduced, the image still remained unnaturally oversaturated. It's a bit of a shame, as the potential of the mini-LED backlit panel is great, but the software presents a clear barrier here.

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 must come to terms with a certain degree of "artificiality" that cannot be circumvented even with professional equipment.

QN90F handles upscaling very well. Materials in lower resolutions, even SD, are enhanced to a clear and sharp image, in which a lot of detail in the background can be seen. This is a significant advantage, as the television makes older content or everyday television look considerably better than on most budget screens. However, the issue of overscan remains, which is the trimming of the screen edges, and this cannot be turned off in Samsung TVs. This can cause some subtitles on the screen to disappear or Auntie's face from the wedding on the VHS tape to be slightly cut off. 😉

Digital image processing also works well. In the menu, we find a function called "noise reduction," which can smooth tonal transitions and improve the reception of lower quality materials, e.g. from YouTube. At the medium setting, the effect is most beneficial – it does not heavily interfere with details, while eliminating the problem of "stepping" in colours. However, it is worth remembering that the function can be quite aggressive and removes natural grain from older films, so it is best to use it in moderation.

In the case of lower quality materials and how the 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 sharp, without the overscan effect, meaning no cropped edges. Of course, it is not at the level of top models, and at times one can notice slight jaggedness on the contours, but in this price range, the effect is fully acceptable.

However, the actual digital image processing performs significantly worse, which, apart from the upscaling, effectively does not exist. In the JP7 menu, we will not find any option that would effectively smooth out unwanted tonal transitions or reduce noise in the image. As a result, the signal reaches the panel in a very raw form, which, with heavily compressed materials (e.g. from YouTube), leads to visible posterisation. Either it is a flaw in the software or a very strange design decision, because in earlier Sharp models this function was available and, crucially, worked with noticeable effect. Here, we are left to deal with whatever the source provides us, without any digital support from the image processor.

The QN90F is equipped with a panel that has a maximum refresh rate of 165 Hz, and although this advantage will primarily be appreciated by PC gamers, it is still worth highlighting. In films or sports broadcasts, we are limited to the classic 120 Hz, but this is not a cause for concern. In practice, the additional motion smoother is of greater importance here. With the "Motion Clarity" setting, we can adjust the picture to our own preferences. The blur reduction option is responsible for fluidity and ghosting in sports. Meanwhile, the "judder reduction" function improves motion smoothness in productions shot at 24 frames, such as films and series. If we set it high, the film appears smoother and more fluid than it was actually shot. Lower values, on the other hand, preserve its cinematic "rawness" with a visible film frame.

The motion fluidity on the Sharp JP7 is quite mediocre, and the reason is simple: the television uses a 60Hz panel. This instantly makes it difficult 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 smoothness feature, which we can control in films using a slider called De-judder. Lower settings provide a more raw, "cinematic" (framey) image, while higher settings add artificial smoothness. We suggest setting it somewhere in the middle of the scale, that is in the range of 3-5 – this is the best compromise to avoid the soap opera effect while also eliminating the tiring stuttering of the image. Interestingly, in the menu, we also find a "motion blur removal" slider, which usually indicates the presence of a 120Hz panel. However, with the JP7, it does not enhance the image at all and serves rather as a dummy – it is meant to look good in the settings, but technically it has no right to operate on this panel.

QN90F has almost everything to be the perfect television for gamers. There’s no need to remind anyone of features like four HDMI ports, VRR, ALLM, or refresh rates reaching even 165 Hz. The Game Motion Plus mode deserves great praise, as it is a unique motion smoother for games. Thanks to this, it adds a few “artificial” frames and makes the image generated from the console look smoother than it should. This is a very unique solution in the world of televisions – rival systems usually do not offer this – and that is why Samsung has had a strong selling point among gamers for years, even despite the lack of support for the still niche Dolby Vision in games.

[UPDATE] We have updated our tests of Samsung televisions from the 2025 lineup due to the release of software version 1131, which restored the crucial feature for gamers, HGiG.

So why do we say "almost" the perfect screen? Unfortunately, like in recent Samsung models, we noticed an issue with the lack of the HGiG feature. This solution allows the television to leave the control of tone mapping up to the console, so that games look exactly as intended by the creators. What's worse, this feature was previously present and disappeared after software updates. Instead of minor improvements, we got a step back. It’s a shame, because without this absence, the QN90F could truly be the ideal choice for gamers in the miniLED category.

As we mentioned earlier, the 60Hz panel is not a feature that will attract gamers to the Sharp JP7. Perhaps for the casual player, 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 television to low latency game mode (input lag).

• Game Menu: Which is hard to call a full-fledged “Game Bar,” as the functionality here is minimal. Aside from enabling ALLM, there’s only a game-specific motion smoother which we recommend avoiding as it introduces very noticeable artifacts and worsens responsiveness.

• Dolby Vision Gaming: For Microsoft consoles.

Unfortunately, the list of shortcomings is significantly 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 PS5 or Xbox Series X. Another shortcoming is VRR, which means that during frame drops, we are exposed to screen tearing. The lack of proper implementation of the HGiG standard is also very problematic. 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 over-bright image with cut-off details. Sharp JP7 is a proposition solely for very casual gamers.
