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

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.

Since the E8Q is a twin of the U7Q, it’s no surprise that the quality of the HDR effect is almost identical. On paper, it looks promising – a peak brightness of 800 nits can impress in many scenes. Fragments like the 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 are supposed to be displayed on a dark background. In such situations, the dimming algorithms try to preserve contrast but end up dimming what should shine the brightest. Instead of dazzling details, we get almost invisible points of light. This is typical for Mini-LED in this price segment and is not surprising – but it’s worth knowing that the HDR effect won't always be fully preserved. Fortunately, the color reproduction offers reasons to be satisfied. A coverage of the DCI-P3 color gamut at around 94% is a very good result, and the applied quantum dot layer (more specifically, PFS) does its job – colors are saturated and vibrant, especially with 4K content.

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.

Testing the Hisense E8Q in Filmmaker mode, we were hoping for a neutral image close to the director's vision. Unfortunately - although on paper it doesn't look bad (the color reproduction errors are not significant), in practice the image feels somewhat unnatural. The reason? Too strong an increase in blue and a lack of red in the white balance. The effect? The scenes look cool, and the white appears slightly bluish. Alongside the U7Q model, we also noticed a specific approach to brightness management here. The brightness reproduction curve for HDR content (EOTF) shows that the TV can significantly dim small, bright elements of the screen to maintain contrast - but sometimes it goes too far. On the other hand, it can excessively brighten larger, very bright parts, 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 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.

The calibration of the Movie mode brought really good results, especially regarding SDR content. The white balance was successfully adjusted, which gave the image a natural look – it appeared almost reference-level. The colors were well-saturated, and the overall perception of the content improved significantly. Unfortunately, when we moved to HDR materials, the well-known problems from the U7Q model returned. The TV still tends to “do things its own way,” which is evident from the analysis of the EOTF brightness characteristic – despite calibration, the E8Q still dimmed small details in the shadows, while the bright areas of the screen could sometimes be excessively boosted. In practice, this means that in darker scenes, some of the tiniest details could simply disappear. Although it must be admitted 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 noticeable, and it is worth keeping this in mind.

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.

In the case of older materials with lower quality, a gentle smoothing of tonal transitions is often useful. The Hisense E8Q, like the U7Q, has the "Smooth and Gradient Picture" feature, but unfortunately, its effectiveness leaves much to be desired. The “Low” setting is almost imperceptible in operation, while higher settings simply blur details instead of improving transitions. The good news is that the feature does not compromise the film grain, which allows it to maintain the image structure. On the plus side, the scaling is commendable. The television can fairly sensibly transform older content to a higher resolution—without artificially emphasizing contours or excessive sharpening. Though it does not match the best models in this category, it performs quite well for its class.

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.

Like the U7Q, the E8Q model is a fast television designed for dynamic content. It supports 144 Hz refresh rates in 4K resolution, and if for some reason someone is still gaming in Full HD, it can achieve even 240 Hz. This is a significant advantage, especially for PC users looking for maximum fluidity. In everyday use, the television performs very well. The "Ultra Motion Smoothness" mode provides us with two sliders, allowing for personalized image settings – whether it’s more cinematic with preserved film frames or heavily smoothed, almost "series-like." It’s good that the manufacturer gives a choice here instead of imposing one style. On sports materials, live broadcasts, or in games – motion appears clean and stable. Sure, it’s not at the level of OLEDs, but for this price range, the E8Q performs really well.

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.

The Hisense E8Q does not hide its gaming pedigree. The specification alone reveals that we are dealing with a television that will work great as a gaming screen. Variable Refresh Rate (VRR)? Yes. Automatic low latency mode (ALLM)? It's there too. Additionally, there is impressive refreshment – 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 – like in the U7Q – remains support for HGiG. It's a pity, because this feature makes it easier to match the brightness curve to the capabilities of a particular television, improving visual consistency with the intentions of HDR game creators. Without it, one has to manually tweak the settings, which does not always yield a satisfying result.
