Hisense A6N vs Samsung S90D / S94D 48" (WRGB OLED)

Unfortunately, the HDR effect quality on A6N is not impressive. A peak brightness of 250 nits doesn’t allow for spectacular highlights, and HDR looks rather muted, more like ordinary SDR. This will not satisfy more demanding users who want to enjoy high-quality movie content. Additionally, the color gamut coverage is not very impressive either: DCI-P3 at 82% is an average result that doesn’t let you fully enjoy vivid colors in HDR material.

In the tested movie scenes, the Samsung S90D delivers impressive brightness levels, exceeding 800 nits in the first four shots—a very strong result. In the final shot, featuring a full-screen burst of sunlight, brightness drops to approximately 400 nits, which is still acceptable. Notably, larger versions of this model exceed 1,000 nits, offering even more impressive performance. Additionally, the colour space coverage of DCI-P3 at 97% ensures rich and realistic colour reproduction, greatly enhancing image quality. For those considering the size of the S90D, it is worth noting that larger variants with QD-OLED panels deliver even better HDR performance, making them an excellent choice for those seeking optimal visual fidelity.

In the color reproduction category, the Hisense A6N in Filmmaker Mode leaves much to be desired. Although the mode's name suggests we should expect faithful movie color reproduction, the reality is different. The TV has significant picture quality problems. The white balance issue is particularly noticeable for both HD and 4K material, as it is heavily skewed by a dominance of blue. This results in artificial, cool tones, clearly visible in the comparison photo below. The ColorChecker test further confirms these errors, which are compounded by low color gamut coverage.

The gamma luminance curve shows a serious problem maintaining the 2.4 level, with the plot well below the reference value. That leads to excessive image brightening and washed-out blacks. The EOTF curve for 4K material also indicates brightness problems. At the low end there is a pronounced bump caused by the TV's excessive brightening, which negatively affects picture quality. This image behavior prevents fully enjoying movies and requires manual correction.

The Samsung S90D television 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 too warm, and users who switched from Standard mode may experience a slight shock. It is worth noting that this state of affairs is caused by poor settings, for example, in the white balance, rather than the Filmmaker mode itself. In both SDR and HDR content, the device shows drops in blue colour, causing colours to become warmer than they should be. In practice, this means that some shades, such as sky blue or skin tones, may appear less natural and more tinged with pink or yellow. The Colour Checker test confirms these deviations, showing shifts towards warmer tones. In SDR content, the gamma graph indicates slight fluctuations, causing the image to be minimally darker, especially in shadows. This may affect less distinct details in darker scenes. Meanwhile, in 4K HDR materials, the EOTF curve is above the recommended line, which leads to some parts of the image being displayed too brightly, potentially causing clipping in the brightest areas. Overall, the Samsung S90D presents a solid picture straight out of the box, but for the best results, especially with more demanding content, additional calibration is recommended.

Hisense A6N offers in its settings options and tools to adjust many picture parameters, which we used. As for the white balance, we managed to remove the excess blue; this is clearly visible in the comparison photo below, where the boy in the image practically "comes to life". A large improvement can also be seen in the gamma brightness response, as the TV no longer has serious issues with overbrightening the entire picture. Unfortunately, the same cannot be said for 4K content, where the EOTF curve could not be fully corrected due to this model's exceptionally low brightness. For HDR content we use dynamic tone mapping, which allows recovery of many details despite lifting the midtones. For this TV that brings more benefits than drawbacks. The errors that remain visible in the color gamut test and the ColorChecker for 4K content stem from the low color gamut coverage and are difficult to eliminate because of the TV's characteristics. Even so, the image tonality is much better, so we recommend calibrating the factory settings, which are far from ideal.

After calibration, the S90D TV delivers an even more impressive performance in movie mode. The white balance for both HD and 4K HDR content is now nearly perfect. While there are still some minor imperfections, they are so subtle that they don't significantly impact the overall image quality. The colours are more balanced, offering a natural depiction of details, especially in scenes that require precise colour accuracy.

It's important to note that the 48-inch model features a WOLED panel, which differs from the larger sizes. This results in a smaller coverage of the wide colour gamut, meaning it doesn't offer the same rich colours as the 65-inch version, which is equipped with a QD-OLED panel.

Contrast has also seen a substantial improvement. The gamma curve after calibration is much closer to the ideal line, achieving a better balance between bright and dark areas of the image. The EOTF curve, which previously showed issues with overly bright scenes, now performs much better, retaining more detail in the bright sections of the image, especially in HDR content.

Let's see how A6N handles low-quality material. When it comes to smoothing tonal transitions, the lack of a function to reduce posterization or smooth tonal transitions in low-quality sources, such as broadcast TV or DVD, may be noticeable to more demanding viewers. As for digital processing, the model was rendered correctly and the branches were free of the typical jagged edges. The image has a pronounced sense of plasticity and is soft, which may appeal to those who prefer that kind of picture style.

The S90D TV excels in smoothing tonal transitions, offering natural and seamless colour shifts. Thanks to its advanced technology, it ensures a smoother visual experience overall. The noise reduction feature can further enhance tonal transitions, making it beneficial in certain situations. However, it’s important to note that enabling noise reduction may also smooth out the film grain, which can detract from the cinematic feel. For this reason, it's advisable to use the feature sparingly, preserving the natural grain that adds depth and authenticity to the content.

Samsung continues to impress with its scaling capabilities, with the S90D effectively processing lower-resolution content. The image is sharp and clear, maintaining proper outlines and presenting details accurately. For example, tree branches are rendered well, with no noticeable jagged edges that would compromise image quality. Thanks to the effective scaling, even lower-resolution materials are displayed attractively, making it a great choice for users who enjoy content from diverse sources, such as regular antenna or cable television.

The 60 Hz panel in Hisense A6N will likely please people who enjoy watching movies, because the TV offers an "ultra motion smoothing" feature that lets you adjust the image's motion, making it choppier or smoother and more cinematic. As for motion blur, it is rather average. You can see quite noticeable blur, especially on dark backgrounds, which is a common trait in this class of TVs.

The S90D TV features a 120 Hz panel, which can be "overclocked" to 144 Hz with the appropriate PC setup, delivering exceptional motion fluidity. Samsung has long offered a range of image clarity settings on a ten-point scale, allowing users to fine-tune the display to their liking. In the UFO test, the OLED panel ensures no ghosting, with pixel response being instantaneous and perfectly capturing dynamic movements. OLED technology, in this regard, is considered one of the best on the market. The image remains incredibly sharp and detailed, even during fast-paced action, making the S90D TV a top choice for gamers and sports fans alike.

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 players. Still, it offers several features that can make gaming more enjoyable. The TV supports functions such as ALLM (automatic low-latency mode), VRR (variable refresh rate) and Dolby Vision, which let you enjoy better picture quality and smoother motion in games that support those technologies. Moreover, the low input lag means in-game reactions are fast, which is crucial, especially in fast-paced titles. Thanks to these features, although the TV isn’t the ideal choice for demanding gamers, it provides solid support for those who value comfortable gaming without complicated settings. It’s an ideal solution for people who want to enjoy gaming without high hardware demands while still having access to modern technologies that enhance gameplay quality.

The S90D TV is perfectly designed with gamers in mind, 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). These technologies ensure smoother gameplay and faster screen response, enhancing comfort during extended gaming sessions. The Game Bar feature also provides convenient access to settings like aspect ratio, which can be particularly useful for different game types. For PC users, the television offers an impressive refresh rate of 144Hz, with Nvidia and AMD graphics cards supporting G-Sync and FreeSync, further boosting image smoothness. While the lack of Dolby Vision support may be a limitation, it’s worth noting that this technology is less commonly used in gaming compared to movies. Nevertheless, the S90D still provides excellent features for gamers, making it a top choice for those seeking high-quality visuals and advanced gaming technologies.
