Hisense A6N vs Samsung OLED S95H (S99H) (QD-OLED)

The HDR performance on A6N is unfortunately underwhelming. A peak brightness of just 250 nits doesn't allow for spectacular highlights, and HDR looks rather washed out, more like standard SDR. This won't satisfy more demanding users who want to enjoy high-quality film content. Additionally, colour gamut coverage isn't very impressive either, with DCI-P3 at 82% being a mediocre result that doesn't let you fully enjoy vibrant colours in HDR material.

When it comes to pure brightness, the S99H is an astronomically bright TV. Its peak brightness in film scenes can exceed 2,800 nits. Whatever the scene, you can expect powerful HDR effects that are almost blinding, which is exactly what we want from a top‑tier display. By nature, an OLED panel can't maintain that extreme brightness in very bright, full‑screen frames the way it can with small bright highlights, but the results are still excellent. In a bright scene from The Meg the sun still exceeded 2,200 nits. That means the S99H was able to hold a 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.

Colour gamut coverage

The S99H also handles colours exceptionally well, thanks directly to the QD‑OLED panel used here. Whether the test used synthetic test patterns or measurements with film material in the background, the results remained very high. The S99H easily covers almost 100% of the DCI‑P3 gamut, and in the most demanding space, BT.2020 it reaches nearly 90%. That's absolute top‑tier performance. These results match what we saw in the new SQD‑Mini‑LED displays, and in real film scenes they even surpass RGB Mini LED displays.

In the colour reproduction category, the Hisense A6N in Filmmaker Mode leaves much to be desired. Although the mode's name suggests we should expect faithful rendering of cinematic colours, the reality is different, and the TV has considerable picture-quality issues. The problem with white balance is particularly noticeable for both HD and 4K material, with a strong bias toward blue. This results in artificial, cool tones, clearly visible in the comparison image below. The ColourChecker test further confirms these errors, which are compounded by low colour-gamut coverage.

The gamma luminance curve shows a serious problem maintaining a 2.4 target. The curve sits well below the reference value, leading to excessive image brightening and washed-out blacks. The EOTF curve for 4K material also indicates brightness issues, with a significant early overshoot caused by the TV's excessive brightening that negatively affects picture quality. This picture profile prevents fully enjoying films and requires manual adjustment.

Samsung offers a whole host of picture modes and features, but we traditionally 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 flaws. These are mainly a slight deviation in white balance in SDR content and a slightly low gamma. As a result, the picture in a dark room can be a little too bright compared with the reference value of 2.4, which is the standard for watching films with the lights off. These are, of course, small issues, because overall colour reproduction remains very good and the errors in ColorChecker measurements are not large. However, we know that for a screen of the S99H's calibre you can and should expect even more, so we subjected it to professional calibration.

Hisense A6N offers options and tools in its settings for adjusting many picture settings that we utilised. When it comes to white balance, we managed to eliminate excess blue – this effect is clearly visible in the comparison image below, where the boy in the picture almost "comes to life." A significant improvement can also be noticed in the gamma brightness characteristic – the television no longer has serious issues with excessively brightening the entire image. Unfortunately, the same cannot be said for 4K materials, where the EOTF curve could not be fully corrected due to the exceptionally low brightness of this model. For HDR content, we use dynamic tone mapping, which allows for the recovery of many details despite the boosting of midtones in the image. For this television, this provides more benefits than drawbacks. The errors that are still visible in the test with the colour palette and Colour Checker for 4K content arise from low colour gamut coverage and are difficult to eliminate due to the television's characteristics. Nevertheless, the tonal quality of the image is significantly better, which is why we recommend calibrating the factory settings, which are far from ideal.

After professional calibration, FILMMAKER mode looks practically perfect. Because Samsung offers a rich set of advanced calibration controls, we were able to tune the colours to an almost perfect level. Above all, we managed to even out the white balance and the gamma curve, which resulted in noticeably improved contrast and correct image modelling. In a profile prepared like this there really isn't a single thing to pick apart or call a fault. After calibration, the S99H can deliver an essentially reference-quality picture.

Let's see how A6N handles low-quality sources. When it comes to smoothing tonal transitions, the lack of features for reducing posterisation or smoothing such transitions in low-quality material like television or DVD may be noticeable to more demanding viewers. As for digital processing, the model was presented correctly and the branches were free of the characteristic jaggedness. The picture has strong three-dimensional modelling and a soft look, which may appeal to viewers who prefer this kind of image style.

Upscaling and digital image processing are handled by Samsung's proprietary NQ4 Gen3 processor. It copes very well with scaling lower-resolution content to 4K. The picture is clear without looking artificial or overly sharp. The only fairly specific drawback appears with very old material recorded at 480p or lower. In such cases the TV can slightly crop the edges of the image.

The processor also does a decent job with artefacts visible in low-bitrate material, for example in heavily compressed YouTube videos. The noise reduction function effectively smooths the picture and reduces posterisation, but it works quite aggressively. It can remove not only unwanted artefacts but also some fine detail, 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 more than keeping every detail, it may prove useful.

The 60 Hz panel in Hisense A6N will probably satisfy people who like watching movies, because the TV offers an "ultra motion smoothing" feature that lets you adjust the image's judder, making it more choppy or smoother, with a soap‑opera effect. When it comes to motion blur, it’s rather average; there’s quite noticeable smearing, especially on dark backgrounds, which is a fairly typical trait for this class of TVs.

Another major advantage of organic panels is very good motion handling. Thanks to the pixels' near-instant response time, the Samsung S99H shows virtually no smearing. Fast-moving objects don't produce visible halos or trailing artefacts, so the TV performs very well for both sport and gaming. One quirk of OLED screens compared with LCD is the way they render low-frame-rate material. With very slow camera movement the picture can appear noticeably more juddery. This can be quite effectively mitigated using frame interpolation. Samsung lets you adjust judder reduction and motion blur reduction separately, so it's easy to find a compromise between a smoother picture and preserving the cinematic feel of the content.

Hisense A6N is a TV that will likely appeal to casual gamers, mainly because of its 60 Hz panel, which may not satisfy more demanding users. Still, it offers a few features that can make gaming more enjoyable. The TV supports ALLM (automatic low latency mode), VRR (variable refresh rate) and Dolby Vision, allowing for better picture quality and smoother motion in games that support those technologies. What's more, the low input lag means in-game reactions are quick, which is crucial, especially in fast-paced titles. Thanks to these features, although the TV is not an ideal choice for demanding gamers, it offers solid support for those who value comfortable gaming without complicated settings. It's an ideal solution for people who want to enjoy gaming without heavy hardware requirements, while still having access to modern technologies that improve the gaming experience.

Samsung S99H is also a top TV for gamers. It offers almost every possible and useful feature... well, perhaps except the obvious lack of Dolby Vision for the Xbox console. It’s equipped with four full-fledged HDMI 2.1 ports with the full 48 Gbps bandwidth. That makes it easy to use frame-rate synchronization VRR or 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 free of 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 minimap, 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 boost smoothness in games. Input lag then rises to around 40 to 50 ms (depending on the strength of the setting), which, compared with the competition, is an excellent result. The system makes gameplay noticeably smoother. So if someone has their eye on a demanding game (e.g. GTA 6 😉) that runs on a console at only 30 fps, the S99H can display it much more smoothly than competing models.
