Samsung S90D / S94D 48" (WRGB OLED) vs Hisense E8Q

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.

Since the E8Q is a twin of the U7Q, it’s no surprise that the quality of the HDR effect is nearly identical. On paper, it looks promising – a peak brightness of 800 nits can impress in many scenes. Moments such as flashes of light in “The Meg” or shots of the sun in “Life of Pi” can indeed evoke a 'wow' effect. But the longer we watch, the more we notice the limitations. The problem arises when small, bright details need to be shown against a dark background. In such situations, the dimming algorithms try to preserve contrast but end up dimming what should shine the most. Instead of dazzling details, we get almost invisible points of light. This is typical for Mini-LEDs in this price segment and is not surprising – but it’s worth knowing that the HDR effect will not always be fully preserved. Fortunately, the colour performance offers reasons to be pleased. Coverage of the DCI-P3 colour gamut at around 94% is a very good result, and the applied layer of quantum dots (more precisely, PFS) does its job – the colours are saturated and vibrant, especially with 4K content.

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.

Testing the Hisense E8Q in Filmmaker mode, we were hoping for a possibly neutral image close to the director's vision. Unfortunately – although it doesn't look bad on paper (the colour reproduction errors are not significant), in practice the image appears not entirely natural. The reason? An overly strong boost in blue colour and a lack of red in the white balance. The effect? Scenes look cool, and the white seems slightly bluish. Alongside the U7Q model, we also noticed a specific approach to brightness management here. The brightness mapping curve for HDR content (EOTF) shows that the television can significantly dim small, bright elements on the screen to maintain contrast – but sometimes it goes too far in this. On the other hand, larger, very bright areas can be excessively brightened, which disrupts tonal balance. This is a compromise that may not suit everyone – especially if you want an as faithful image as possible right out of the box.

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 calibration of the Movie mode yielded really good results, especially when it comes to SDR content. We managed to balance the white levels, which made the image look more natural – it appeared almost reference-quality. The colours were well-saturated, and the overall perception of the content improved significantly. Unfortunately, when we switched to HDR materials, familiar issues from the U7Q model returned. The television still likes to "do its own thing," as evident from the analysis of the brightness characteristic EOTF – despite calibration, the E8Q still dimmed fine details in the shadows, while the bright areas of the screen could be excessively boosted. In practice, this means that in darker scenes, some of the smallest details could simply disappear. Although it must be acknowledged that the entire calibration process brought a lot of good, not everything can be circumvented – even with the use of professional tools. The E8Q can impress with its picture, but in HDR content, its design limitations become apparent, and it is worth keeping this in mind.

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.

In the case of older materials with lower quality, a gentle smoothing of tonal transitions often comes in handy. The Hisense E8Q, like the U7Q, features an "Smoothing and Gradient Image" function, but unfortunately – its effectiveness leaves much to be desired. The "Low" mode is almost imperceptible in operation, and the higher settings do not improve transitions but simply blur the details. The good news is that the function does not compromise film grain, meaning it does not worsen the structure of the image. On the plus side, scaling is commendable. The television is able to sensibly upscale older content to a higher resolution – without artificially accentuating contours or excessive sharpening. Although it does not match the best models in this category, it performs quite well for its class.

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.

Similar to the U7Q, the E8Q model is a fast television designed for dynamic content. It supports a refresh rate of 144 Hz at 4K resolution, and if, for some reason, someone is still gaming in Full HD – it can even reach 240 Hz. This is a significant advantage, especially for PC users looking for maximum smoothness. In everyday use, the television performs very well. The "Ultra Motion Smoothness" mode offers two sliders that allow you to customise the picture to your preference – whether more cinematic with the film frame preserved or highly smoothed, almost "series-like". It's good that the manufacturer provides a choice here instead of imposing one style. On sports material, live broadcasts, or in games – movement looks clean and stable. Of course, it is not at the OLED level, but for this price range, the E8Q performs really well.

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.

Hisense E8Q does not hide its gaming heritage. Even the specifications reveal that we are dealing with a television that will perform excellently as a gaming screen. Variable Refresh Rate (VRR)? It's there. Automatic switching to game mode (ALLM)? That's there too. Additionally, there is impressive refresh rate – 120 Hz in 4K or even 240 Hz in Full HD. Such a set is rare in this price segment. Everything works smoothly and without major surprises. The only missing element – similar to the U7Q – is support for HGiG. It’s a shame, as this feature facilitates adjusting the brightness curve to the capabilities of a specific television, improving visual compatibility with the intentions of HDR game creators. Without it, one has to manually fiddle with the settings, which does not always yield a satisfactory result.
