Samsung S90D / S94D 48" (WRGB OLED) vs Hisense A6Q

In the tested film scenes, the television Samsung OLED 48 S90D achieves impressive brightness results, surpassing 800 nits in the first four shots, which can be considered a very good result. In the case of the final shot, where a fullscreen flash of sunlight is visible, the brightness drops to around 400 nits, but still remains at an acceptable level. However, it's 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 at 97% is an excellent result, which guarantees extremely rich and realistic colour reproduction, further enhancing image 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 in choosing the size of the S90D model, it is worth mentioning that the larger versions of this television offer better HDR effects, and consequently, higher scores in our tests.

The Hisense A6Q is unfortunately difficult to recommend for watching HDR content. The main issues are low brightness and rather modest coverage of a wide colour gamut. The measured brightness of around 300 nits simply isn't sufficient for HDR materials to look impressive. In practice, the picture often resembles standard SDR instead of true HDR with clear differences in brightness and dynamics. Additionally, the colours in such materials do not appear as they should. The television does not utilise additional filters such as QLED or PFS LED, and the coverage of the DCI-P3 colour space at around 80% means that some colours look rather washed out. Consequently, some scenes in HDR materials lose intensity and spectacle, making it difficult to speak of a full HDR experience.

The S90D Samsung 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 can seem overly warm, and users switching from Standard mode may experience a slight shock. It's worth noting that this state of affairs is caused by poor settings, such as in the white balance, rather than the Filmmaker mode itself. In both SDR and HDR content, the device shows drops in blue, 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. Conversely, in 4K HDR materials, the EOTF curve is situated above the recommended line, leading to some parts of the image being displayed too brightly, which can cause clipping in the brightest areas. Overall, the Samsung S90D presents a solid image right out of the box, but for the best results, especially with more demanding content, additional calibration is recommended.

We conducted the tests in the best available mode, namely Filmmaker, however – as is often the case – this does not mean an ideal image straight out of the box. In the case of Hisense A6Q, this mode clearly "swallowed" too much blue in everyday SDR content. In practice, this led to an image with a yellowed white, particularly noticeable on large, bright surfaces. This is not due to poor assumptions of the Filmmaker mode itself or the vision of filmmakers, but rather the factory settings requiring adjustment.
Furthermore, looking at the saturation characteristics and the gamma curve in SDR, as well as EOTF in HDR content, there is a slight tendency to brighten most scenes. As a result, the image often appears brighter than it should, losing a bit of its naturalness. For this reason, we decided to perform a professional calibration to restore the proper colour balance and a more accurate brightness characteristic.

After calibration, the television Samsung OLED 48 S90D in film mode looks even better than one could have presumed. The white balance, for both HD and 4K HDR content, has been improved to nearly perfection. Although minor errors can still be noticed, they are so minimal that they do not significantly affect the quality of the image. The colours are more balanced, which translates to a natural representation of details, particularly in scenes requiring a precise colour palette. It is worth adding that this model in the 48' size is equipped with a WOLED panel that has a different characteristic compared to larger sizes and has a smaller coverage of a wide colour gamut, not offering such rich colours as, for example, the 65-inch version, which is fitted with a QD-OLED panel.

The contrast has also undergone significant improvement. The gamma graph after calibration is much closer to the expected line, providing a better balance between the bright and dark parts of the image. The EOTF curve, which before calibration showed issues with overexposed scenes, now displays better results. This effect allows for greater detail preservation in the bright parts of the image, especially in HDR material.

The colours after calibration in the Hisense A6Q should be assessed in two ways, as everything depends on the type of content. In the case of SDR material, the effect is truly very good. In everyday programmes, series, and films, it is difficult to spot any serious problems with colours. The yellow tint has been effectively removed, and the television no longer brightens the entire image. As a result, the ColorChecker test showed errors below Delta 2 values, which are already outstanding results, allowing us to speak of very high image quality in standard content. Unfortunately, the situation looks significantly worse in the case of HDR material. Yes, the white balance has been corrected and the EOTF curve has been improved, but the limitations of the panel itself remain insurmountable. The lack of support for a wide colour gamut means the television still generates quite significant colour errors. Certain colours simply cannot be displayed by the screen, making them appear less saturated than they should be. It's a shame because even a simple PFS or QLED filter would significantly improve the final effect. The conclusion is therefore simple – the A6Q is really very well suited for SDR content after calibration, while watching HDR content on it should still be approached with caution.

The Samsung OLED 48 S90D television performs very well in smoothing tonal transitions. Thanks to the applied technology, the transitions between colours are more fluid and natural. There is also the option to use the noise reduction function, which further smooths tonal transitions, which can be useful in certain situations. However, it is worth remembering that enabling noise reduction can also lead to the smoothing of desired film grain, which in turn can reduce the cinematic atmosphere of the image. For this reason, caution is advised when using this function, as it is better to leave the natural grain that adds character and authenticity to the content being viewed.

Samsung, as always, does not disappoint and excels at scaling images from lower resolutions. The S90D OLED 48 Samsung television effectively processes lower resolutions, as seen in the visible image. The outline of the model is clear and correct, looking natural and detailed as a result. Moreover, the branches of trees are well replicated, showing no strong jaggedness that could detract from the quality of the image. Thanks to effective scaling, even lower resolution materials look attractive on the screen, satisfying users who prefer a variety of content sources such as regular aerial/cable television.

Upscaling on the Hisense A6Q works quite decently for a television in this price range. Materials of lower resolution are correctly "upscaled" to a higher one, and the image remains clear without artificial edge enhancement or the typical "over-sharpening" found in cheap models. Unfortunately, the digital processing is significantly worse. In practice, it is difficult to speak of any advanced artifact smoothing or problematic tonal transition masking. In heavily compressed films – especially those from YouTube – the television practically struggles with reducing compression blocks and unwanted banding, making the imperfections in the material clearly visible. The A6Q scales the image well, but when it comes to digital processing, it leaves the user alone with the quality of the source.

The S90D television is equipped with a 120 Hz panel, with the possibility of "overclocking" to 144 Hz with the appropriate PC configuration, ensuring exceptional motion fluidity. For years, Samsung has offered a variety of image sharpness settings on a ten-point scale, allowing users to customise the display to their preferences. In the UFO test, thanks to the use of an OLED panel, there is no sign of any blurring. The pixel response is instantaneous and perfectly captures dynamic movements. In this aspect, OLED technology is considered one of the best on the market. The image is incredibly sharp and detailed, even during fast action, making the S90D OLED 48 Samsung television an ideal choice for gamers and sports enthusiasts.

The motion fluidity of the Hisense A6Q is… well — quite mediocre. It’s a television with a native refresh rate of 60 Hz in 4K, which means that the motion of objects on the screen doesn’t always look perfectly smooth. In dynamic scenes in movies or sports, it’s clear that this isn’t the strongest feature of this model. The situation improves significantly with 1080p content when connecting a console or computer, as the A6Q can operate even at 120 Hz then. This is a big plus, especially for gamers. Nevertheless, the clarity of motion still leaves much to be desired; blurring is noticeable, and the response time of the panel indicates that it is not one of this television’s strong points.

The Samsung OLED 48 S90D television is excellently tailored 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 screen responsiveness, significantly enhancing comfort during long gaming sessions. Additionally, the Game Bar feature allows for easy adjustments of settings such as screen ratios, which can be particularly useful in various 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 fluidity. Although the lack of Dolby Vision support may be a downside, it is worth noting that this technology is not as widely used in games as it is in films. Nevertheless, the S90D still offers excellent features for gamers, making it an outstanding choice for those seeking high-quality visuals and advanced gaming technologies.

For such an inexpensive television, the Hisense A6Q can truly surprise with what it offers to gamers. It operates in 4K only at 60 Hz, but when a game switches to performance mode and drops to 1080p, the panel can work even at 120 Hz. This is a significant advantage in this price range, as most titles on consoles don't achieve stable 4K at 120 frames per second anyway. In practice, we are realistically playing at 1080p, and here the A6Q provides very enjoyable gaming experiences. On top of that, there are several features usually found in more expensive models: ALLM, VRR, and Dolby Vision Gaming for Xbox Series X/S. Everything is gathered in one place, in a simple and convenient Game Bar, so there's no need to dig through the entire menu. For such an affordable piece of equipment, it's a really solid set for gamers — perhaps not for the most demanding, but certainly spot on for occasional gaming.
