IFFALCON U85X vs Samsung QN80H

iFFALCON U85 handles HDR in a rather twofold manner – on one hand, it can surprise with solid peak brightness of around 650 nits, which places it well above average in this price segment. This is especially evident in bright, full-screen scenes. Examples from films such as Life of Pi or the final test sequences from The Meg prove that the television can maintain the power and essence of HDR effect when the entire panel needs to "ignite," delivering truly satisfying experiences. However, problems arise in high-contrast scenes, where smaller, bright details appear on the screen; the dimming algorithms prioritize black depth to such an extent that they can stifle the brightness of small light points to just 100 nits, which drastically reduces image dynamics and deprives us of the true "bite" we expect from HDR standards. On a brighter note, however, the colours remain impressive, as the use of the PFS phosphor filter (marketed as QLED by the manufacturer) showcases them very well, achieving nearly 94% coverage of the DCI-P3 colour palette, allowing for a vibrant and rich image in most content.

The Samsung QN80H is undoubtedly a bright TV. In synthetic tests it exceeds the 1000-nit mark, which on paper promises a solid HDR effect. In practice the screen really shows its teeth, although it can't fully spread its wings (or its backlight, if you will 🤔) in every condition. Bright, wide scenes make the best impression. Well-lit outdoor shots and brightly lit scenes look really good on it. Brightness then stays around 700 nits, which provides a noticeable step up in quality compared with standard SDR. Problems start in dark scenes with small, pinpoint highlights. The QN80H tends to dim these strongly, in order to protect black depth at all costs. On the one hand this gives better contrast, on the other... you lose dynamics and the brilliance of fine HDR detail. So the TV has considerable potential, but the dimming algorithm can be too restrictive.

Colour gamut coverage

When it comes to colours it's good as well. The QN80H uses quantum dot technology, and in our measurements it covered 93% of the DCI-P3 colour space and about 70% of BT.2020. Today those results aren't exactly jaw-dropping, but in real-world use they're more than sufficient to deliver a vivid, natural image for most films and TV series. Colours are suitably saturated, and after proper calibration they don't look artificial or overly aggressive.

We tested the factory colours on the iFFALCON U85X model in 'Film' mode, which is definitely the most reliable among all available settings, although it is still far from perfect. The main issue that stands out in both SDR and HDR content is the incorrect white balance – an excess of blue and red components gives the image a slight purple tint, which disrupts the naturalness of the film scenes. An even greater challenge is the way the television manages its brightness. Analyzing the gamma chart for the SDR signal, we noticed significant instability: instead of adhering to the standard value of 2.4, the device oscillates around 2.2, only to suddenly make an unnatural jump towards 3.0. In practice, this leads to confusing effects – large, bright areas on the screen appear too dark, while smaller elements are unnecessarily brightened. A similar characteristic can be found in the EOTF curve, which makes the image unpredictable and loses its cinematic authenticity.

The factory settings of the QN80H performed really well, especially compared with the majority of TVs we receive for testing. Of course, our measurements were taken in Filmmaker Mode, and that's the mode we recommend turning on immediately after the initial setup. For SDR material, our sample was set up surprisingly well. The white balance was very even, colours looked natural, and errors were so small they were hard to notice without measurement equipment. The only weaker point was the gamma. In the brighter parts of the image the TV brightened them a little too much, which at times made the picture lose some depth. Still, we'd like most TVs to look this good straight out of the box.

It fared a little worse in HDR. The white balance was still set correctly, so the problem was not with the colours but with the way the QN80H managed image brightness. This was immediately visible on the EOTF chart. The TV brightened large parts of scenes too much, causing the brightest elements to clip. Interestingly, very small points were often dimmed too much at the same time. As a result, some fine details simply disappeared. So the factory Filmmaker mode in HDR is not bad, but it is definitely not as well calibrated as in SDR.

After professional calibration of the movie mode, we must admit that the result is more than satisfactory – the iFFALCON U85X undergoes a true transformation. Colour errors in SDR content have dropped to a level below 2, which makes them virtually imperceptible to the human eye. We have managed to set the white balance almost perfectly, and brightness management (gamma) has become nearly exemplary. As a result, with standard quality materials, the television simply looks perfect and it is difficult to fault it.

In the case of HDR signal, the situation has also significantly improved, although here the nature of the device becomes a bit more evident. Colour errors have been reduced to around 3, which is an outstanding result in this price range. However, it is worth taking a look at the EOTF graph (available on the right side of the screen in the filters: 4K HDR, gamma / EOTF) to notice what is not immediately visible regarding the brightness management by the U85. Although the reference line looks decent, in real film scenes, the television still interprets the signal “in its own way” due to very aggressive local dimming algorithms. Does this disqualify this model for watching HDR content? Absolutely not. It's simply a typical affliction of almost every Mini-LED, which must reconcile high brightness with the attempt to maintain deep blacks. One simply needs to be aware of these technical limitations, which are unavoidable in this segment.

We saw the biggest difference after calibration in HDR Filmmaker mode. SDR was already very good out of the box, so we didn't have much work to do there. In HDR, however, we managed to get to grips with the way the QN80H handled brightness, as it had been over-brightening most scenes. After calibration the picture is calmer, more natural and much closer to how a faithful image should look.

When it comes to upscaling the image to 4K resolution, the iFFALCON U85X performs well. The device efficiently enhances low-quality signals, making even older materials look clean and clear on the 4K panel. At extremely low resolutions, such as 480p, one can notice slightly jagged edges (especially on fine lines), but let's be honest – this is a scenario that you will encounter only when watching very old recordings, so in everyday use, it is not a real problem.

Much worse is the digital processing aimed at smoothing tonal transitions. Although in the menu we find the “Gradual Smoothing” function, its effectiveness is at least questionable. In practice, it does not effectively eliminate banding (colour banding), and worse, it can cause more harm than good. This filter can be too aggressive in areas where it shouldn’t, artificially smoothing details that should not be altered, such as the natural texture of the face or fine details of skin texture. Instead of improving quality, this function can give the image an unnatural, “plastic” appearance, so it is best to use it with great caution or, preferably, leave it switched off.

Digital image processing in the Samsung QN80H is handled by the second-generation NQ4 AI processor. It's a chip we already know from the manufacturer's earlier models, and it still performs very well, especially with lower-resolution content. The image is effectively upscaled to 4K, but without excessive sharpening and without giving the impression the TV is aggressively trying to improve the source material.

The "Noise Reduction" function also proves useful. It can noticeably reduce posterisation and visible banding in lower-quality material, particularly in low-bitrate streaming. However, it's important to remember that it does not work without side effects. It can remove some film grain and slightly smooth the image. So with a high-quality source we'd leave this function switched off. If, however, someone is more bothered by banding and uneven tonal transitions than by the loss of some grain, "Noise Reduction" can be a really useful addition.

In contrast to budget constructions, which in dynamic sports scenes can resemble a slideshow, the iFFALCON U85X is a heavyweight contender equipped with a panel that has a native refresh rate of 144Hz. However, it is worth noting that in the world of films, series, or sports, we will primarily operate at 120Hz due to the specifics of how image enhancement systems function. Such a fast panel is excellent news for gamers and sports fans as it opens the door to advanced motion settings that simply do not exist in cheaper 60Hz models.

We manage everything from the menu “Motion Clarity”, where instead of using pre-set, often overly aggressive modes, we definitely recommend our own configuration based on two sliders. The most important of these, motion blur reduction, is responsible for fluidity in films – here, it’s best to aim for a value of around 4, which will maintain a natural, cinematic character of motion without falling into the artificial “soap opera effect.” Meanwhile, the first slider, motion blur reduction, is the key to success in sports broadcasts. In this case, it’s worth going all out and setting it to maximum, ensuring that the image during fast actions on the field remains sharp, while troublesome trailing is eliminated.

Motion handling and motion clarity on the QN80H are really good, mainly thanks to the fast panel. In 4K the screen refreshes at up to 144 Hz, and when switched to Full HD and connected to a PC it can reach as much as 240 Hz. That's new for Samsung TVs and a useful addition for people who want to use the TV for PC gaming as well. We were more interested, however, in how the QN80H performs at 120 Hz, because consoles use that refresh rate. Here it performs very well. The panel does not suffer greatly from the smearing typical of VA panels, and light trails behind moving objects are mainly visible on dark backgrounds. That said, it's nothing that would interfere with normal watching of sport or gaming. The TV also has a motion smoothing system that Samsung calls "Wyrazistością obrazu". You can adjust judder reduction and blur reduction separately, so it's easy to tailor its behaviour to films, sport or your own preferences.

iFFALCON U85X is an outstanding piece of equipment for gamers that has just about everything one can expect from a modern screen for consoles or PCs. We find here two full-fledged HDMI 2.1 ports with full bandwidth of 48 Gbps, which opens the door to key technologies such as VRR and ALLM, ensuring smooth gameplay without tearing the image and with minimal latency. The television handles high refresh rates in various resolutions without any problems, and a real curiosity is the mode that allows for achieving up to 240Hz when dropping down to Full HD quality. The whole thing is managed by the Game Bar (which is a faithful copy from TCL), allowing for instant switching of picture modes, customising the interface appearance, or even adding a virtual crosshair in the middle of the screen.

The Samsung QN80H is a TV that stands out when it comes to gaming features. The biggest new addition for 2026 is DLG mode, which allows refresh rates of up to 240 Hz when the image is switched to Full HD. It's an option aimed mainly at PC users, but it also shows that Samsung is still heavily developing the gaming side of its TVs. However, the list of advantages doesn't end there. The QN80H has four full-fledged HDMI 2.1 ports, which is still not standard at this price point. So you can connect several consoles, a PC or a soundbar at the same time without having to wonder which port supports the full video capabilities. The TV also supports VRR, ALLM and HGiG, so it's hard to fault its basic feature set.

A downside is the lack of Dolby Vision, which may matter primarily to Xbox Series X owners. However, this is not a flaw that disqualifies the QN80H as a gaming TV. Samsung has a feature most manufacturers still lack: its proprietary motion smoothing, Game Motion Plus. It's a motion smoothing system that works in game mode too, allowing you to improve the smoothness of titles running at 30 or 60 frames per second without a drastic increase in input lag. In practice, Game Motion Plus can make a much bigger difference than the Dolby codec, especially in more demanding games that don't offer a 60 FPS mode. The image becomes noticeably smoother, while controls remain sufficiently responsive. So despite the lack of Dolby Vision, the QN80H remains one of the best-equipped gaming TVs in its class.
