Samsung QN80F 100" vs Hisense U7S Pro

When it comes to HDR in Filmmaker mode, the QN80F can make a great first impression. Our laboratory tests have shown that under the best conditions, the television is capable of achieving brightness exceeding 1200–1300 nits. These are truly excellent results, making HDR effects in many films look incredible. The television is simply bright enough not to need to artificially adapt the image – the bright parts of scenes have the right 'power' and actually look like a light source. Of course, the laboratory is one thing, and everyday viewing is another. In practice, in film scenes, brightness generally oscillates in the range of 700–1100 nits. These are still great values that, in most cases, provide a strong sense of realism and make the lights on the screen truly capable of blinding. The problem arises in exceptionally challenging sequences, where, like almost every mini-LED, it reveals its limitations. A good example is Sicario 2: the scenes with the helicopter in the night sky look much weaker, and the lights lose intensity, dropping to around 370 nits, making it hard to speak of serious admiration. To this, we must add the issue of colours. Although we are dealing with a QLED, the coverage of the DCI-P3 colour palette is around 90%. This is a rather average result for a quantum dot television. In practice, this means that some colours may appear less saturated than we would expect, especially in demanding HDR productions.

Let's start with the fact that the U7S Pro is an impressively bright television – in calibrated mode, our measuring equipment indicated a staggering 2200 nits of peak brightness! This is an absolutely remarkable result, considering that this model is positioned rather as a mid-range option.

However, as we know, peak brightness on test patterns is one thing, and actual film scenes are another. Unfortunately, in real video materials, the backlight power clearly drops. Although in the most demanding moments, the television can still exceed the 1000-nit barrier – which is still an excellent result, perfectly aligned with the mastering standards of most HDR films – the real challenge comes from the aggressively tuned local dimming algorithms. Because of this, small, bright details such as stars or the moon in the night sky are noticeably dimmed. The television tries at all costs to maintain deep blacks, which is of course understandable, but unfortunately, this comes at the expense of the dynamics and brilliance of the HDR effect itself.

One must commend the colour reproduction. The new U7S Pro is a QLED design that provides very wide coverage of the colour palette. Unlike last year's model (U7Q Pro), this year's variant is a "true" QLED, rather than a solution based on a PFS filter. As a result, the colour saturation has clearly increased, and coverage of the most demanding BT.2020 colour space has surpassed the 81% barrier.

The Samsung QN80F performs best in Filmmaker mode, which is designed to replicate the creators' intentions as accurately as possible. And indeed – this is the mode in which the television showcases its potential. But let’s not kid ourselves, it is far from perfect. In SDR content, the issue of white balance came to the forefront. Slightly lacking greens and a noticeable excess of reds caused the screen to take on a pinkish hue. You don't even need meters to notice this – in everyday viewing, the subtly shifted colour palette could be quite noticeable, and in colour checker tests, the colours would literally "pop" out of their reference fields. With HDR content, the situation looked a bit better, as the white balance was closer to ideal, but another problem arose – brightness management. The EOTF curve often caused the image to become too bright, which spoiled the sense of contrast, and in dynamic scenes, it led to a slight "flicker" in perception. We had already mentioned this when discussing black levels and HDR. The good news, however, is that Samsung provides a lot of tools for improvement. The QN80F allows for truly detailed calibration, including a 20-point white balance. And since the manufacturer has left us so many options, we decided to check how the television would perform after a thorough adjustment.

We tested the U7S Pro model – as we always do – in the best factory-calibrated picture mode, namely Filmmaker Mode. We can evaluate the displayed colours in two ways. The most disappointing was the profile designed for viewing SDR content, that is, traditional television, YouTube, and other less demanding materials. The picture was clearly yellowed, which turned out to be a direct consequence of a poorly set white balance. As our graphs show, there is a significant deficiency of the blue component, which drastically affected the overall colour temperature. This is clearly visible on the ColorChecker charts as well as on the graphs of the colour palette itself, where most samples leaned towards yellow. Fortunately, the factory HDR mode fared much better – there, the colour errors were around a Delta E value of 3, which is already a really solid result.

After calibrating the QN80F, it immediately showed that it was capable of much more. The previous pinkish tint disappeared, and the white balance finally looks like it should – natural and without excessive deviations. The colours gained depth, and the image became more saturated and cohesive, making watching films simply more enjoyable. It's a bit like removing a light haze from the screen – suddenly everything appears sharper and clearer. The management of brightness has also improved. The television no longer gets easily lost in dynamic shifts, and the EOTF graph shows that the curve tracking is significantly more stable. Of course, there are no miracles – the limited number of zones still means that small bright elements can be slightly washed out, but that's a result of the design itself, not the settings. After this correction, the QN80F feels like a more mature piece of equipment, and watching films finally provides the satisfaction expected from a television even in a higher class.

We know, however, that the company Hisense is capable of much more – as previous generations have demonstrated – which is why we couldn't simply overlook the factory shortcomings of the U7S Pro model in everyday content. As is often the case, the television underwent professional calibration. The conclusions? This process brought about a colossal change. After manually adjusting the white balance and supplementing the deficiencies in the blue component, the annoying yellow tint disappeared as if by magic. White became naturally pure, and skin tones gained the appropriate, healthy hue. Importantly, calibration not only tamed the capricious SDR mode but also allowed us to extract the maximum potential from the panel, reducing average colour reproduction errors to levels nearly imperceptible to the human eye. The only thing we must criticise after the whole process is the very nature of the Mini-LED backlight and its specific interaction with the HDR signal. The aggressively tuned local dimming algorithms significantly interfere with the EOTF brightness curve. As a result, the backlight does not always work perfectly with the creator's intention – depending on the scene being viewed, the curve can noticeably deviate either above or below the reference, which at times disrupts the ideal dynamics of HDR imagery.

With lower quality materials, such as films from YouTube or older television recordings, the QN80F can display its strengths and weaknesses. If strange colour transitions or artefacts start to appear on the screen, it is worth using the noise reduction function. The best setting is at "medium" – it smooths out problematic sections while not blurring the entire image. However, one compromise must be remembered: this function always removes film grain. If someone enjoys its presence in older productions, it is better to keep the reduction turned off, as the grain simply disappears regardless of the setting.

Resolution scaling, or upscaling, is another strong point of Samsung. The QN80F may not be the best television on the market in this regard, but it performs very well in its price range, which is very important for such a large size as a 100-inch screen. Even lower quality materials can gain a second life – the image becomes sharper, more readable, and overall much more pleasant to perceive. A weak point remains overscan, which is the slight cropping of edges in very low resolutions (e.g., 576p), something that has been a longstanding issue for Samsung. Fortunately, this is practically of no consequence when watching HD and 4K content on a daily basis.

The digital processing of lower quality signals is at a very high level here, thanks to the MediaTek Pentonic 800 processor used in the U7S Pro. The upscaling performance is equally impressive, meaning the television’s ability to enhance lower resolution signals to 4K. We did not notice any unnatural, sharp contours on the screen, and our test image featuring the model simply looked attractive.

The QN80F features a 144 Hz panel, and this is evident in practice – with full refresh, the image is remarkably smooth, and motion blur remains at an acceptable, barely noticeable level. However, this mode is primarily aimed at PC gamers. The most important reference point in everyday use remains the 120 Hz refresh rate, and this is where a certain discrepancy arises. During the UFO test, we noticed a splitting of the contours of rapidly moving objects – it looked as if the television had the BFI (Black Frame Insertion) feature permanently activated, which in practice led to an unpleasant effect of double edges. We do not yet know whether this is a software issue or a characteristic of this model, but in its current form, such behaviour is hard to commend.

The Hisense U7S Pro uses a panel with a maximum refresh rate of 165 Hz in 4K, and in game mode, it can reach up to 330 Hz at Full HD resolution. However, it is important to remember that these highest figures do not significantly matter in everyday use, as most content is still limited to a maximum of 120 Hz (for example, when gaming on a console). Nevertheless, the television handles motion quite well and performs really decently for an LCD construction.

There is little to criticise about the fluidity itself. In the menu, we find a motion smoother called "Motion Enhancement", which hides two sliders: blur reduction and judder reduction. These allow for manual configuration of the smoother, which works well in both films and sports, effectively enhancing the raw television signal.

The Samsung QN80F gives the impression of a television designed with gamers in mind. On the list of advantages, we have a 144 Hz panel, four full-featured HDMI 2.1 ports, complete support for VRR and ALLM, as well as one of the best-designed gamebars on the market. Added to this is the Game Motion Plus motion smoother, which also works in games without actually increasing input lag, making the QN80F an absolute standout in this category. In practice, this means you can enjoy smoother images without losing responsiveness, which is a dream for many console gamers!

As is usual with Samsung, there is a lack of Dolby Vision in games, and this is no longer surprising. However, we were much more surprised that in the models from 2025… the HGIG feature has disappeared. This feature allowed consoles such as the PlayStation 5 and Xbox Series X to perfectly adjust HDR tone mapping to the capabilities of the television. In the current firmware of the QN80F, this option is simply missing – it seems more like a mistake than a conscious decision by the manufacturer, but on the day of testing, we must acknowledge that HGIG is not available. Due to this one absence, the QN80F, instead of being an almost ideal television for gamers, becomes a device that is only "almost" ideal. This is quite a shame because, aside from this, Samsung has created a model that truly sets a high standard in the gaming hardware segment.

[UPDATE] We have updated our Samsung television tests for the 2025 model year due to the release of software version 1131, which has restored the crucial gaming feature HGiG.

If you plan to connect a console or PC to the U7S Pro, you will be more than satisfied – this television is excellent equipment for a gamer. Hisense has not spared any expense and has included as many as 4 HDMI 2.1 ports with full bandwidth of 48 Gbps. You won’t need to juggle cables as each port will handle the full set of features. We have an automatic game mode (ALLM) and VRR, which operates in a wide range from 48 Hz to an impressive 330 Hz. Of course, that 330 Hz is currently a gimmick for owners of powerful PCs, as consoles will be limited to 120 Hz, but it’s good to have that buffer for the future. The Game Bar also works very well during gaming. It’s a handy menu bar for gamers, where you can quickly change the picture mode, enable a crosshair in the centre of the screen, and even change the display aspect ratio to ultra-wide without having to exit to the main television settings, which will be appreciated by fans of PC simulators. The only downside worth mentioning is the improper implementation of the HGiG format in games. The issue is that the television ignores instructions from the console regarding the image generated in HDR10 and continues to forcefully interfere with the image it produces, trying to "enhance" it in its own way. This makes proper HDR configuration in the console menu (where you set brightness on symbols/checkerboard) somewhat difficult.
