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

Unfortunately, the quality of HDR effect on A6N is not impressive. A peak brightness of 250 nits does not allow for spectacular effects, and HDR is rather pale, resembling more of a regular SDR. This state of affairs will not satisfy more demanding users who want to enjoy high-quality film materials. Additionally, the color gamut coverage is also not very impressive – DCI-P3 at 82% is an average result that does not fully allow for enjoying vibrant colors in HDR materials.

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 category of color reproduction, the Hisense A6N model in Filmmaker Mode leaves a lot to be desired. Although the name of the mode suggests that we should expect faithful reproduction of cinematic colors, the reality is different – the television has significant problems with image quality. The issue with white balance is particularly noticeable, both for HD and 4K content, which is heavily skewed by the dominance of blue. This results in artificial, cold tones, as clearly seen in the comparative photo below. The Colour Checker test additionally confirms these errors, which are exacerbated by low color gamut coverage. The gamma brightness characteristic shows a serious problem with maintaining a level of 2.4 – the graph is significantly below the reference value, leading to excessive brightness and washed-out blacks. The EOTF curve for 4K content also indicates brightness issues – at the beginning, there is a substantial peak due to the TV's excessive brightness, which negatively impacts image quality. Such image characteristics do not allow for full enjoyment of watching films and require manual adjustment.

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 options and tools in its settings for correcting numerous image settings that we have utilized. When it comes to white balance, we managed to eliminate the excess blue color – this effect is clearly visible in the comparison photo below, where the boy in the image almost "comes to life." A significant improvement can also be observed in the gamma brightness characteristics – the TV no longer has serious issues with overly brightening the entire image. Unfortunately, the same cannot be said for 4K content, 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 mid-tones in the image. In the case of this TV, it provides more benefits than drawbacks. The errors that are still visible in the color palette test and Colour Checker for 4K materials stem from low color gamut coverage and are difficult to eliminate due to the characteristics of the television. Nevertheless, the tonal quality of the image is significantly better, which is why we recommend calibrating the factory settings that 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 check how the A6N handles low-quality materials. When it comes to smoothing tonal transitions, the lack of posterization reduction or smoothing of tonal transitions in low-quality materials, such as television or DVD, may be noticeable for more demanding viewers. As for digital processing, the model was presented correctly, and the branches were free of characteristic jaggedness – the image is very plastic and soft, which may appeal to people who prefer this kind of image 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 the Hisense A6N will likely please those who enjoy watching movies, as the TV offers an "ultra motion smoother," allowing us to adjust the motion blur – either more choppy or smoother, theatrical. As for trailing, it performs quite average – noticeable trailing can be seen, especially on dark backgrounds, which is a rather typical feature in this tier 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.

The Hisense A6N is a television that will likely appeal to casual gamers, primarily due to its 60 Hz panel, which may not satisfy more demanding users. Nevertheless, it offers several conveniences that can enhance the gaming experience. The television supports features such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and Dolby Vision, allowing for better image quality and smoother motion in games that support these technologies. Furthermore, the low input lag ensures quick responses in-game, which is crucial, especially in dynamic titles. With these features, although the television is not the ideal choice for demanding gamers, it provides solid support for those who value comfortable gaming without complicated settings. It is an ideal solution for individuals who want to enjoy gaming without high hardware requirements while still having access to modern technologies that improve the gaming experience.

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.
