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

In the tested film scenes, the television Samsung S90D achieves impressive brightness results, exceeding the 1000 nits barrier in the first four shots, which can be considered an outstanding result. In the case of the last shot, where a full-screen flash of sunlight is visible, the brightness drops to around 500 nits, but still remains at a very good level. Additionally, the television impresses with a DCI-P3 colour gamut coverage measurement of 98%, ensuring an extraordinarily rich and realistic colour reproduction, further enhancing the picture quality. This result makes the Samsung S90D an ideal choice for those expecting high-quality images in a variety of lighting conditions.

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 television has been tested in Filmmaker mode, which offers good colour reproduction, although with some imperfections that may be noticeable to more discerning users. This mode may seem a bit too warm, and users who switched from Standard mode may experience a slight shock. It is worth noting that this situation 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 exhibits drops in blue colour, making colours 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, resulting in a minimally darker image, especially in shadows. This can affect less defined details in darker scenes. Conversely, in 4K HDR materials, the EOTF curve is above the recommended line, leading to overly bright displays in certain parts of the image, which can cause clipping in the brightest areas. Overall, Samsung S90D presents a solid picture right out of the box, but for the best effects, 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 Samsung S90D television in movie mode looks even better than one might have expected. The white balance, for both HD and 4K HDR content, has been improved almost to perfection. Although minor flaws can still be noticed, they are minimal enough not to significantly affect the picture quality. The colours are more balanced, which translates to a natural reproduction of details, especially in scenes requiring a precise colour palette. It is worth noting that this model in this size is equipped with a WOLED panel, which has less coverage of the wide colour gamut and does not offer 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 graph post-calibration is much closer to the expected line, providing better balance between bright and dark areas of the image. The EOTF curve, which prior to calibration showed issues with overexposed scenes, now presents better results. This effect allows for greater detail retention in bright parts of the image, especially in HDR materials.

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.

Television S90D performs very well at smoothing tonal transitions. Thanks to the applied technology, the transitions between colours are more fluid and natural. There is also the option to use noise reduction, 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 desirable film grain, which in turn could reduce the cinematic atmosphere of the image. For this reason, caution is advised when using this feature, as it is better to leave the natural grain that adds character and authenticity to the viewed content.

Samsung, as always, does not disappoint and excels in the area of scaling images from lower resolutions. The S90D Samsung television effectively processes lower resolutions, as can be seen in the visible image. The outline of the model is clear and accurate and, as a result, looks natural and detailed. Moreover, the branches of the trees are well-rendered, showing no significant jaggedness, which could diminish the image quality. Thanks to effective scaling, even materials in lower resolution present attractively on the screen, pleasing users who prefer various sources of content such as regular antenna/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.

Samsung S90D TV is equipped with a 120 Hz panel, with the possibility of "overclocking" to 144 Hz with the appropriate PC configuration, providing exceptional motion fluidity. Samsung has been offering a variety of sharpness settings on a ten-point scale for years, allowing users to adjust the display to their preferences. In the UFO test, thanks to the use of an OLED panel, there's no sign of any smearing. 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 picture is extremely sharp and detailed, even during fast actions, making the S90D TV 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 S90D TV is perfectly adapted to the needs of gamers, offering four HDMI 2.1 ports that support key features such as Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and HDR Gaming Interest Group (HGIG). With these technologies, gamers can enjoy smoother and more responsive gameplay, significantly affecting comfort and performance during intense gaming sessions. An additional advantage of the television is the special Game Bar, which allows for easy management of game settings. This functionality enables quick adjustments to parameters such as changing the TV's screen aspect ratio, which can be useful in various games and types of gameplay. Users can easily customise their preferences, making the use of the TV during gaming even more convenient and enjoyable. As for PC users, the TV pleasantly surprises. When connected to a computer, the panel is capable of achieving a refresh rate of 144Hz, and users of Nvidia or AMD graphics cards can enjoy features such as G-Sync and FreeSync. It should be noted, however, that the TV does not support Dolby Vision, which may be a drawback - but it's worth bearing in mind that Dolby Vision is not as popular for games as it is for films. Nevertheless, the S90D TV still offers excellent features for gamers, making it a great choice for gaming enthusiasts who seek top-notch picture quality and modern technological solutions.

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.
