Hisense A6N vs Samsung S90D / S94D 48" (WRGB 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.

In the tested movie scenes, the Samsung OLED 48 S90D television achieves impressive brightness results, exceeding 800 nits in the first four shots, which can be considered a very good outcome. In the case of the last shot, where a full-screen burst of sunlight is visible, the brightness drops to around 400 nits but still remains at an acceptable level. However, it is worth noting that this model in larger sizes offers higher values, exceeding the "barrier" of 1000 nits. Additionally, speaking of the DCI-P3 colour space coverage value of 97% is an excellent result, which guarantees extremely rich and realistic colour reproduction, further enhancing the picture quality. However, once again it should be remembered that the panel in the 65' variant equipped with a QD-OLED panel will be even better in this aspect. For those hesitating about the size of the S90D model, it is worth noting that larger versions of this television offer a better HDR effect, and consequently, a higher score in our tests.

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.

The S90D Samsung TV has been tested in Filmmaker mode, which offers good colour reproduction, although with some imperfections that may be noticeable to more demanding users. This mode may seem a bit too warm, and users who switched from Standard mode may experience a slight shock. It's worth considering that this state of affairs is caused by poor settings, such as white balance, rather than the Filmmaker mode itself. Both in SDR and HDR content, the device exhibits drops in blue, causing colours to appear warmer than they should. In practice, this means that some shades, like sky blue or skin tones, may seem less natural and take on a pinkish or yellowish tint. The Colour Checker test confirms these deviations, showing shifts towards warmer tones. In SDR content, the gamma chart indicates minor fluctuations, resulting in a slightly darker image, especially in the shadows. This may affect the clarity of details in darker scenes. Conversely, in 4K HDR materials, the EOTF curve is above the recommended line, leading to some portions of the image being too bright, which can cause clipping in the brightest areas. Overall, the Samsung S90D presents a solid image straight out of the box, but for the best results, particularly with more demanding content, additional calibration is recommended.

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 calibration, the Samsung OLED 48 S90D in movie mode looks even better than one might have assumed. The white balance, for both HD and 4K HDR content, has been improved to near perfection. Although minor errors can still be noticed, they are so minimal that they do not significantly affect the picture quality. Colours are more balanced, which translates into a natural reproduction of details, especially in scenes requiring a precise colour palette. It’s worth noting that this model in the 48' size is equipped with a WOLED panel that has different characteristics compared to larger sizes and has a smaller coverage of a wide colour gamut, not offering as rich colours as, for example, the 65-inch version, which is equipped with a QD-OLED panel.

Contrast has also seen significant improvement. The gamma chart after calibration is much closer to the expected line, providing better balance between the bright and dark portions of the image. The EOTF curve, which showed issues with overexposed scenes before calibration, now shows better results. This effect allows for greater detail retention in bright parts of the image, particularly in HDR material.

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.

The Samsung OLED 48 S90D television performs exceptionally well in smoothing tonal transitions. Thanks to the technology used, the transitions between colours are more fluid and natural. It is also possible to utilise the noise reduction feature, which further smooths tonal transitions, which can be useful in some situations. However, it's worth remembering that turning on noise reduction can also lead to the smoothing of desired film grain, which may reduce the cinematic feel of the picture. For this reason, caution is advised when using this feature, as it's better to leave the natural grain that adds character and authenticity to the content being viewed.

Samsung, as always, does not disappoint, and in terms of scaling images from lower resolutions, it performs excellently. The S90D OLED 48 Samsung television effectively processes lower resolutions, as seen in the visible photo. The outline of the model is clear and correct, making it look natural and detailed. Furthermore, the branches of the trees are well reproduced, showing no significant jaggedness that could detract from the image quality. Thanks to effective scaling, even lower resolution materials look attractive on the screen, satisfying users who prefer diverse content sources such as regular antenna/cable television.

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.

The S90D television is equipped with a 120 Hz panel, with the ability to "overclock" to 144 Hz with the right PC configuration, providing exceptional motion smoothness. Samsung has been offering a variety of image clarity settings on a ten-point scale for years, allowing users to customise the display to their preferences. In the UFO test, thanks to the use of an OLED panel, there's no question of any ghosting. The response time of the pixels is instantaneous and perfectly captures dynamic movements. In this aspect, OLED technology is considered one of the best on the market. The picture is extremely sharp and detailed, even during fast action, making the S90D OLED 48 Samsung television the perfect choice for gamers and sports enthusiasts.

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.

The Samsung OLED 48 S90D television is well-suited to the needs of gamers, offering four HDMI 2.1 ports that support features such as Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and HGIG (HDR Gaming Interest Group). With these technologies, gamers can enjoy smoother gameplay and faster on-screen response, significantly enhancing comfort during long gaming sessions. Additionally, the Game Bar feature allows for easy adjustment of settings, such as aspect ratios, which can be particularly useful in different types of games. For PC users, the television offers an impressive refresh rate of 144Hz, and Nvidia and AMD graphics cards support G-Sync and FreeSync, further improving image smoothness. Although the lack of Dolby Vision support may be a drawback, it's worth noting that in gaming, this technology is not as widely used as in films. Nevertheless, the S90D still offers excellent features for gamers, making it a great choice for those seeking high-quality visuals and advanced gaming technologies.
