Samsung QN80H vs Samsung OLED S95H (S99H) (QD-OLED)

Samsung QN80H is without a doubt a bright TV. In synthetic tests it breaks the 1000-nit barrier, which on paper already promises a solid HDR effect. In practice the screen really shows its claws, though it can't fully spread its wings (or its backlight 🤔) in every situation. The best impression comes from bright, expansive shots. Sunlit exteriors or heavily lit scenes look really good on it. Brightness then stays around 700 nits, which gives a noticeable step up in quality over standard SDR. Problems start in dark scenes with small, pinpoint highlights. The QN80H tends to heavily dim them, doing everything it can to protect black levels. On one hand we gain better contrast, on the other... we lose some of the dynamics and the sparkle of fine HDR details. The TV therefore has considerable potential, but the dimming algorithm can be too restrictive.

Color gamut coverage

Colors are good too. The QN80H uses quantum dot technology, and in our measurements it covered 93% of the DCI-P3 space and about 70% of BT.2020. Today those results won't exactly blow anyone away, but in real-world use they're more than enough to deliver vivid, natural-looking images in most movies and TV series. Colors are properly saturated and, after proper tuning, don't look artificial or overly aggressive.

When it comes to brightness alone, the S99H is an astronomically bright TV. Its peak brightness in movie scenes can exceed 2800 nits! Regardless of the scene, you can count on powerful HDR effects that practically blind you, and that's exactly what we expect from a top-tier screen. It's inherent to OLED panels that in very bright, full-screen shots they won't sustain as high a brightness as they do with small highlights, but the results are still excellent. In a bright scene from the film The Meg, the sun still exceeded 2200 nits. That means the S99H was able to maintain higher brightness than most Mini LED screens on the market. In terms of brightness, the S99H is currently the best OLED TV we've tested.

Color gamut coverage

The S99H also handles color exceptionally well, which is a direct result of the QD-OLED panel used here. Regardless of the test scenario, whether synthetic test patterns or measurements with film material in the background, the results stayed at a very high level. The S99H easily covers almost 100% of the DCI-P3 gamut, and for the most demanding color space it reaches nearly 90% of BT.2020. That's top-tier performance on the market. These results match what we saw in the new SQD-Mini-LED screens, and in real movie scenes they even outperform RGB Mini LED displays.

The QN80H's factory settings were really good, especially compared with most TVs that come into our tests. Of course, we performed measurements in Filmmaker Mode, and that's the mode we recommend turning on right after the initial setup. In SDR material our unit was set up surprisingly well. The white balance was very even, colors looked natural, and the errors were so small they were hard to spot without measurement equipment. The only weak point was the gamma. In brighter parts of the image the TV brightened them a bit too much, so the picture sometimes lost a little depth. Even so, we'd like most TVs to look this good straight out of the box.

It was a bit worse in HDR. The white balance itself was still set correctly, so the problem wasn't with the colors but with how the QN80H managed image brightness. You could see that immediately on the EOTF chart. The TV brightened large parts of scenes too much, causing the brightest elements to blow out. Interestingly, at the same time very small points were often dimmed too much. As a result some fine detail simply disappeared. So the factory Filmmaker Mode in HDR isn't bad, but it's definitely not as well calibrated as in SDR.

Samsung offers a whole host of picture modes and features, but as usual we recommend choosing Filmmaker Mode, especially if you want the most faithful rendering of the creators' intent. Out of the box the TV is tuned very well, though it has minor shortcomings. This mainly concerns a slight drift in white balance in SDR content and a slightly low gamma. As a result, in a darker room the image can be a bit too bright relative to the reference gamma of 2.4, which is the standard for watching films with the lights off. These are of course small issues, since overall color reproduction remains very good and the errors in ColorChecker measurements are small. However, we know that from a screen of the S99H's class you can and should expect even more, so we had it professionally calibrated.

The biggest difference after calibration was 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 tame 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 picture should look.

After professional calibration, FILMMAKER mode looks virtually perfect. Because Samsung offers a rich set of advanced calibration features, we were able to tune the colors to an almost perfect level. Most importantly, we were able to even out the white balance and the gamma curve, which resulted in noticeably better contrast and a more natural image dimensionality. With a profile prepared like this, there's really nothing to nitpick or call a flaw. After calibration, the S99H is capable of delivering an essentially reference-quality image.

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

The "Noise Reduction" feature also proves useful. It can noticeably reduce posterization and visible banding in poorer-quality material, particularly in low-bitrate streaming. However, it's important to remember that it doesn't work without side effects. It can remove some film grain and slightly smooth the image. So with a good-quality source we'd leave this feature off. If, however, banding and uneven tonal transitions bother you more than losing some grain, "Noise Reduction" can be a really useful addition.

The proprietary Samsung NQ4 Gen3 processor handles upscaling and digital image processing. It does a very good job scaling lower-resolution material to 4K. The picture is sharp but doesn't look artificial or overly sharpened. The only fairly specific drawback appears with very old footage shot at 480p or lower. In those cases the TV can slightly crop the edges of the image.

The processor also copes quite well with artifacts visible in low-bitrate material, for example heavily compressed YouTube videos. The noise reduction feature effectively smooths the image and reduces posterization, but it works rather aggressively. It can remove not only unwanted artifacts but also some fine details and even natural film grain. We, wanting to preserve maximum fidelity to the source material, chose not to use it. However, if someone values a clean, as-smooth-as-possible image over keeping every detail, it can be useful.

Motion blur and motion handling 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 high as 240 Hz. That's new for Samsung TVs and a nice bonus 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, since consoles use that refresh rate. Here it's really good. The panel doesn't have a big problem with the smearing typical of VA panels, and slight trails behind moving objects are mostly visible on dark backgrounds. This is nothing that would interfere with normal sports viewing or gaming. The TV also includes a motion smoothing system that Samsung calls "Image Clarity." You can adjust judder reduction and blur reduction separately, so it's easy to tailor its operation to movies, sports, or your own preferences.

Another major advantage of OLED panels is excellent motion reproduction. Thanks to the pixels' near instant response time, the Samsung S99H practically produces no smearing. Fast-moving objects don't show noticeable halos or trailing artifacts, so the TV performs very well for both watching sports and gaming. One quirk of OLED screens compared with LCDs is how they render low frame rate material. With very slow camera movement the image can appear noticeably more stuttery. This can be quite effectively mitigated using a frame interpolation system. Samsung lets you adjust judder reduction and blur reduction separately, making it easy to find a compromise between smoother motion and preserving the cinematic character of the content.

Samsung QN80H is a TV that scores very well on gamer-oriented features. The biggest new addition for 2026 is DLG mode, which allows refresh rates up to 240 Hz when the image is switched to Full HD resolution. This option is aimed mainly at PC users, but it also shows that Samsung is still heavily developing the gaming side of its TVs. That’s not the end of the list of advantages. The QN80H has four full-featured HDMI 2.1 ports, which in this price range still isn’t standard. You can therefore connect multiple consoles, a PC, or a soundbar at the same time without worrying which input supports the full picture capabilities. The TV also supports VRR, ALLM, and HGiG, so it’s hard to fault its basic feature set. One downside remains the lack of Dolby Vision, which may matter especially to Xbox Series X owners. That said, it’s not a flaw that rules out the QN80H as a gaming TV. Samsung includes a feature still missing from most manufacturers: its proprietary motion interpolator, Game Motion Plus. It’s a motion interpolator that also works in game mode, 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 Dolby’s processing, especially in more demanding games that don’t offer a 60 FPS mode. The image becomes noticeably smoother while controls remain responsive enough. So despite the lack of Dolby Vision, the QN80H is still one of the best-equipped TVs for gamers in its class.

Samsung S99H is also an excellent TV for gamers. It offers almost every useful feature... well, maybe except the obvious lack of Dolby Vision for Xbox consoles. It's equipped with four fully functional HDMI 2.1 ports with the full 48 Gbps bandwidth. Thanks to that we can easily use frame-rate synchronization VRR and automatic low-latency mode (ALLM). This year Samsung also has no issues with proper HGiG support, so HDR setup on a console is quick and without unnecessary complications. Samsung is also known for interesting extras in its TVs. In the Game Bar menu you'll find options to add an on-screen crosshair, enlarge the mini-map, or change the aspect ratio of the displayed image (PC).

Particularly noteworthy is Samsung's feature: Game Motion Plus. It's Samsung's proprietary motion-smoothing system that uses interpolation to increase smoothness in games. Input lag then rises to around 40 to 50 ms (depending on the strength of the setting), which is an excellent result compared to the competition. The system makes gameplay noticeably smoother. So if someone has their eye on a demanding game (e.g., GTA 6 😉) that runs at only 30 frames per second on console, the S99H can display it much more smoothly than competing models.
