Samsung QN80F 100" vs Hisense U7S Pro

When it comes to HDR in Filmmaker mode, the QN80F can make a great first impression on you. Our lab tests showed that under the best conditions, the TV can achieve brightness exceeding 1200–1300 nits. These are truly remarkable results, which make HDR effects in many films look incredible. The TV is simply bright enough that it doesn’t need to artificially adapt the picture – bright parts of scenes have the right "power" and actually look like a light source. Of course, the lab is one thing, and everyday viewing is another. In practice, during movie scenes, brightness usually oscillates between 700–1100 nits. These are still great values that, in most cases, give a strong sense of realism and make the lights on screen really capable of dazzling you. The problem arises in exceptionally challenging sequences, where, like almost every mini-LED, it reveals its limitations. A good example is Sicario 2: scenes with helicopters 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. This leads us to the topic of colors. Although we are dealing with a QLED, the coverage of the DCI-P3 color palette is about 90%. This is fairly average for a quantum dot TV. In practice, this means that some colors may appear less saturated than we would expect, especially in demanding HDR productions.

Let’s start by saying 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 impressive result, considering that this model is positioned as mid-range.

However, as we know, peak brightness on test patterns is one thing, and actual movie scenes are another. Unfortunately, in real video materials, the backlight power clearly drops. While in the most demanding moments the television can still exceed the 1000 nit barrier – which is still a great result, perfectly fitting the mastering standards of most HDR films – the truly challenging aspect turns out to be the aggressively tuned local dimming algorithms. Because of them, 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 black levels, which is of course understandable, but unfortunately, this comes at the cost of dynamics and the brilliance of the HDR effect itself.

The color reproduction is worth praising. The new U7S Pro is a QLED construction that provides very wide color gamut coverage. Unlike last year's model (U7Q Pro), this year's variant is now a “true” QLED, rather than a solution based on a PFS filter. As a result, color saturation has noticeably increased, and coverage of the most demanding BT.2020 space has exceeded the 81% barrier.

Samsung QN80F performs best in Filmmaker mode, which is designed to faithfully convey the creators' intentions. And indeed – it is a mode in which the TV showcases its potential. But let’s not deceive ourselves, it is far from perfect. In SDR content, a problem with white balance became apparent. Slight deficiencies in green and a clear excess of red caused the screen to take on a pinkish hue. You don’t even need measuring tools to notice this – in everyday viewing, the slightly shifted color palette could be quite noticeable, and in color checker tests, colors were even "jumping" out of their reference fields. With HDR content, the situation was a bit better, as the white balance was closer to ideal, but another problem emerged – brightness management. The EOTF curve often caused the image to become too bright, which spoiled the perception of contrast, and in dynamic scenes led to a slight "flickering" in the reception. We actually already mentioned this in the sections about black levels and HDR. The good news, however, is that Samsung provides a lot of tools for improvement. The QN80F allows for really detailed calibration, including a 20-point white balance. And since the manufacturer left us so many options, we decided to see how the TV would perform after solid corrections.

We tested the U7S Pro model – as always – in the best factory-tuned picture mode, which is Filmmaker Mode. We can evaluate the displayed colors in two ways. The most disappointing was the profile intended for watching SDR content, such as traditional television, YouTube, and other less demanding materials. The picture was clearly too yellow, which turned out to be a direct consequence of a poorly set white balance. As our graphs show, there is a huge deficiency of the blue component here, which drastically affected the overall color temperature. This is clearly evident on the ColorChecker charts and the graphs of the color palette itself, where most samples veered toward yellow. Fortunately, the factory HDR mode performed significantly better – there, the color errors hovered around a Delta E value of 3, which is already a really solid result.

After calibrating the QN80F, it immediately showed that it is capable of much more. The pink tint that could previously spoil the reception has disappeared, and the white balance finally looks as it should – natural and without excessive deviations. The colors have gained depth, and the image has become more saturated and consistent, making movies simply more enjoyable to watch. It's a bit like removing a light haze from the screen – suddenly everything seems sharper and clearer. Brightness management has also improved. The television no longer gets lost so easily in dynamic changes, and the EOTF graph shows that the curve tracking is much more stable. Of course, there are no miracles – the limited number of zones still means that small, bright elements can be slightly brightened, but that is due to the construction itself, not the settings. After this adjustment, the QN80F feels like a more mature piece of equipment, and watching movies finally provides the satisfaction one expects from a television even in the higher class.

However, we know that the Hisense company can do much more – as previous generations have proven – which is why we simply couldn't leave the factory flaws of the U7S Pro model in everyday content. As always in such cases, we subjected the television to professional calibration. The conclusions? This process brought about a colossal change. After manually adjusting the white balance and compensating for the deficiencies in the blue component, the annoying yellow tint disappeared like magic. The white became naturally pure, and skin tones gained the proper, healthy hue. Importantly, the calibration not only tamed the capricious SDR mode but also allowed us to squeeze the maximum from the panel's potential, reducing the average color reproduction errors to values almost imperceptible to the human eye. The only thing we have to nitpick after the entire process is the very nature of the Mini-LED backlighting and its specific cooperation with the HDR signal. The aggressively tuned local dimming algorithms significantly interfere with the EOTF brightness curve. As a result, the backlighting does not always work perfectly with the creator's intent – depending on the scene being viewed, the curve can noticeably run either above or below the reference, which at times disrupts the perfect dynamics of HDR image.

With lower quality materials, such as YouTube videos or older television recordings, the QN80F can showcase its stronger and weaker points. If strange color transitions or artifacts start appearing on the screen, it's worth using the noise reduction function. The best setting is at the "medium" level – it smooths out the problematic segments without blurring the entire image. However, one compromise must be kept in mind: this function always removes film grain. If someone enjoys its presence in older productions, it's better to leave the reduction turned off because, regardless of the setting, the grain simply disappears.

Resolution scaling, or upscaling, is another strong point of Samsung. The QN80F may not be the best TV on the market, but it performs very well in its price range, which is very important for such a large size as a 100-inch screen. Even low-quality materials can gain a second life – the image becomes sharper, more readable, and overall much more pleasant to view. A weak point remains overscan, or slight trimming of edges in very low resolutions (e.g., 576p), which has been a longstanding issue for Samsung. Fortunately, in everyday viewing of HD and 4K content, this practically doesn’t matter anymore.

The digital processing of lower quality signals is at a very high level here, thanks to the MediaTek Pentonic 800 processor utilized in the U7S Pro. The upscaling itself, which is the TV's ability to enhance lower resolution signals to 4K, is also performing well. We did not notice any unnatural, sharp edges on the screen, and our test image with the model looked simply attractive.

The QN80F features a 144 Hz panel, and this is evident in practice – with full refresh, the image is exceptionally smooth, and motion blur remains at an acceptable, barely noticeable level. However, this mode is mainly aimed at PC gamers. The most important reference point in everyday use remains a 120 Hz refresh rate, and here a certain discrepancy arises. During the UFO test, we noticed the blurring of contours of quickly moving objects – it looked as if the television had the BFI (Black Frame Insertion) function permanently enabled, which in practice led to an unpleasant double edge effect. We do not yet know if this is a software issue or a characteristic of this model, but in its current form, it is difficult to praise such behavior.

The Hisense U7S Pro features 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's important to note that these highest numbers have little significance in everyday use, as most content supports a maximum of 120 Hz (e.g., while gaming on a console). Nevertheless, the TV handles motion quite well and performs really decently for an LCD construction.

There's hardly anything to complain about regarding fluidity. In the menu, we find a motion smoothness enhancer called "Motion Enhancement," which hides two sliders: blur reduction and judder reduction. They allow for manual configuration of the smoothness enhancer, which works well for both movies and sports, effectively improving the raw television signal.

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 HDMI 2.1 ports, complete support for VRR and ALLM, and one of the best-designed game bars on the market. In addition, there's the Game Motion Plus motion smoother, which works in games without actually increasing input lag, making the QN80F an absolute standout in this category. In practice, this means that you can enjoy a smoother picture without losing responsiveness, which is a dream for many console gamers!

As usual with Samsung, there’s a lack of Dolby Vision in games, and that's not surprising anymore. However, what surprised us much more is that in the 2025 models… the HGIG feature has disappeared. It was the feature that allowed consoles like PlayStation 5 or Xbox Series X to perfectly match HDR tone mapping to the capabilities of the television. In the current firmware of the QN80F, this option is simply not available—it seems more like a mistake than a conscious decision by the manufacturer, but on the day of testing, we have to acknowledge that HGIG is not available. Because of this one missing feature, the QN80F goes from being an almost perfect television for gamers to an "almost" perfect device. It's quite a shame because aside from this, Samsung has created a model that really sets the bar high in the gaming hardware segment.

[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 HGiG for gamers.

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 gamers. Hisense didn't spare any expense and included 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 package of features. We have an automatic game mode (ALLM) and VRR, which works over a wide range from 48 Hz to a cosmic 330 Hz. Of course, those 330 Hz are currently just a gimmick for owners of powerful PCs, as consoles will still be limited to 120 Hz, but it's good to have that reserve 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, turn on a crosshair in the center of the screen, and even change the aspect ratio to ultra-wide without going into the main settings of the television, which PC simulator fans will appreciate. The only downside worth noting is the incorrect implementation of the HGiG format in games. This means that the television ignores the instructions from the console regarding the image generated in HDR10 and constantly meddles with the image it produces, trying to "enhance" it in its own way. Because of this, the correct configuration of HDR in the console menu (where brightness is set on the logo/checkerboard) is somewhat complicated.
