Samsung QN80F 100" vs Hisense U7S / U77SE

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.

The Hisense U7S has considerable potential for HDR display, but it cannot exploit that potential in every scene. On a test pattern it reaches around 1,100 nits, so the backlight itself is very strong. In our brighter film scenes we measured about 640 to 745 nits. That is still plenty for the sun or bright highlights to have a clear bloom and to show an advantage over SDR material. When the TV needs to brighten a larger portion of the image, it handles it fairly well.

The problem appears with small highlights on a dark background. Each of the 192 zones covers an area much larger than a tiny point on the screen. If the TV were to light that whole zone strongly, it would also brighten the area around the highlight. Hisense tries to avoid that and dims the entire zone. This makes blacks look better, but a small bright object that should attract the eye also loses intensity. That is why in two more demanding scenes we recorded only 297 and 154 nits. The difference is large: in one shot HDR can impress, and in the next small highlights are noticeably muted. The U7S therefore prioritises preserving deep blacks, even at the expense of bright details. With that number of zones it is an understandable compromise, but worth bearing in mind — the peak 1,100 nits tells us about the backlight’s capability, not how brightly the TV will show every element of a film.

Colours

Hisense describes the U7S as ULED, but that is a marketing name, and it is a PFS phosphor backlight that expands the colour palette here. In our measurements the TV covered about 91% of the DCI-P3 colour space and 71% of BT.2020. Those are good results, though they fall short of the best screens on the market. The largest shortfall is in green — the TV does not even reach the DCI-P3 boundary here, so the most intense shades will be less saturated than they should be. Most colours in HDR films and series still look suitably vibrant. A positive is the repeatability of the results. Gamut coverage on test patterns and in film scenes is practically identical.

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.

Out-of-the-box colours on the Hisense U7S are decent, but there are a few areas to improve. In SDR there is a red bias in the white balance, which makes the picture too warm and, in places, slightly pink. You can notice this on faces and on bright, neutral surfaces. The gamma also runs below the target, so the TV brightens the image, particularly in darker areas. That makes shadow detail easier to see, but the scene loses some of its depth.

In HDR the white balance is somewhat more even, but not entirely neutral, with a shortage of blue in the mid-tones and a lack of red in the brightest parts. A bigger issue is how brightness is rendered. The EOTF curve shows a large portion of the mid-tones being lifted, causing the picture to look brighter than the source intends. Color Checker measurements are also weaker than in SDR: many errors are around 3 to 4, and some reach as high as 8. Colours can therefore look attractive, but they are not always faithful to what we should see. There is room for improvement here and we will see how much can be corrected through calibration.

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.

Calibration of the Hisense U7S brought the biggest improvements with SDR material. We managed to even out the white balance, so the previous warm tint has gone and whites and greys now look neutral. Gamma is also now very close to the reference, and the TV no longer brightens the picture unnecessarily, so darker scenes have regained depth. Color Checker measurements confirm the improvement: most errors are below 2. That means the picture is very well set up for watching regular TV and SDR films. It wasn't as smooth in HDR. There is no effective way to correct the EOTF curve, so the TV still interprets a film's brightness somewhat on its own. It brightens parts of the picture and can dim the brightest elements depending on the scene and the behaviour of the local dimming. Calibration could not eliminate this. This is also reflected in the Color Checker results, where many errors remain around 3–4 and a few exceed 7. So the result in SDR is really very good, but in HDR we must accept that the TV adds its own interpretation of brightness to the image.

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 handling of lower-quality material is fairly mediocre on the Hisense U7S. The Pentonic 700 chipset used here does not cope particularly well with strong compression artefacts. The menu includes a "Smooth and Gradient Image" function, but its performance leaves much to be desired. At the low setting tonal transitions show little improvement, although at least the image does not suffer. The medium and high settings still do not remove obvious banding between shades, and they begin to blur details; in our test material even parts of characters' faces disappeared. Interestingly, film grain remains untouched at every level. If you do use this feature, stick to the low setting. Its current behaviour needs refinement, but that is mainly down to the chipset used here.

Upscaling to 4K performs much better. Lower-resolution content gains in legibility, edges are well reproduced, and fine elements look sharp. That does not mean it recovers details that were never in the recording, but the TV makes good use of what it receives from the source. Another plus is that it does not crop the image edges, even with an SD signal.

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.

Motion handling on the Hisense U7S is decent thanks to the 144 Hz refresh rate. For films there is also a motion smoother with adjustable judder and blur reduction. You can therefore keep a more cinematic motion or increase smoothness if jerky camera pans bother you. The high refresh rate is also useful for sports and gaming, but unfortunately it does not solve the panel's biggest problem.

That problem is pixel response time. Fast-moving objects leave long, clearly visible trails, as our UFO test shows. It looks worst on dark backgrounds, where the trail behind the object is particularly pronounced. So motion can be smooth, but the moving object itself loses sharpness, and that difference on the U7S is fairly easy to notice.

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.

The Hisense U7S has a lot to offer gamers. You get two HDMI 2.1 ports and support for 120 Hz at Full HD, 1440p, and 4K, so modern consoles’ capabilities are well used. When connected to a PC you can use 144 Hz at 4K or switch the resolution to Full HD and run 240 Hz. So there’s a wide choice, although it’s worth remembering the motion smearing mentioned earlier, which the high refresh rate does not eliminate. VRR and ALLM are also present. The first helps prevent tearing when frame rates in a game change. The second automatically switches the TV into game mode, so you don’t have to dig through the menu each time. VRR works from 48 to 240 Hz, with the highest refresh rate available in Full HD. Xbox users can also play in Dolby Vision, including at 120 Hz. Importantly, this format does not introduce significant input lag here. The Game Bar also looks very good. It’s easy to read, visually appealing, and lets you quickly check what signal the TV is receiving. There are also handy gaming settings at your fingertips, including shadow brightening. If it’s hard to spot an opponent in a dark game, you can improve visibility without digging through the entire menu.

Our biggest complaints concern HGiG. Hisense continues to do its own tone mapping, which makes setting HDR on the console confusing. You adjust a checkerboard test pattern and the TV continuously adapts how it looks. As a result, the moment the pattern disappears does not correctly indicate the screen’s brightness limit, and it’s easy to set the value too high. For this model it’s better to set the target HDR peak brightness on the console to about 900 to 1000 nits, rather than relying on the configurator.
