Samsung OLED S90D / S94D (WRGB OLED) vs Hisense E7Q PRO / E79Q PRO

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.

When it comes to the quality of the HDR effect, the E7Q PRO is unfortunately not a television that can impress with brightness alone. In real film materials, we measured around 250–300 nits, which is simply too little for HDR to look spectacular. There is a lack of that "spark" in bright details, highlights, and light effects, and in many HDR scenes, it can resemble good SDR more than true cinematic HDR. The consolation in all this is the colours. We managed to confirm that the E7Q PRO is a PFS-type television, meaning it has an additional filter that improves colour gamut coverage. As a result, even if the brightness does not deliver, the colours in HDR content can be appropriately saturated and pleasing to the eye, without the feeling of a "washed-out" image.

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.

In terms of colour reproduction, we tested the Hisense E7Q Pro in Movie mode, which turned out to be the best built-in preset without a doubt. This mode, unlike the Eco, Standard or Dynamic settings, offers the most natural colours straight out of the box. Although no factory mode is completely free of flaws, the E7Q Pro deserves high praise for its colour rendering in standard SDR content. The colour palette is very well tuned here, and the errors in the Color Checker tests often did not exceed a value of 3, which is an outstanding result rarely seen in such affordable televisions. The only drawback we noted in SDR is the tendency to darken some elements of the image, as indicated by the slightly raised gamma graph. The television performs slightly worse with colours in HDR mode. Here, colour errors become noticeable to the naked eye, mainly due to a lack of blue in the white balance. This causes the colours on the screen to be too warm, and for some viewers, they may even seem “too cinematic.” Of course, to improve these parameters, we proceeded with professional calibration.

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.

In the case of materials with a standard dynamic range (SDR), our actions in Filmmaker mode turned out to be largely cosmetic 😉. We mainly focused on a subtle adjustment of the white balance and equalising the gamma curve, which allowed us to recover details in the darker areas of the image that previously tended to get lost. However, it is worth noting that the E7Q Pro unit we tested was exceptionally well-made at the factory. We remind you that these parameters depend on the specific unit – with mass production, factory calibration can be random, so your unit may require slightly different intervention. The biggest beneficiary of professional calibration was undoubtedly HDR mode. This is where we did the most work, which brought spectacular results. We managed to effectively tame the excessive warmth of the image, caused by a factory deficiency in blue colour. After calibration, the colour errors were reduced to a significantly lower level, which will certainly please those who watch a lot of streaming content in HDR format, expecting faithful reproduction.

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.

When it comes to upscaling and digital image processing, the E7Q PRO deserves praise. The scaling performs really well and does not dramatically fall behind much more expensive, advanced televisions. Lower-quality materials can look clean and sensible, without the impression that the image is artificially "enhanced." However, the smoothing function presents a bit worse. Indeed, it can be effective and improve tonal transitions in poor quality materials, but at the same time, it can introduce undesirable effects. It sometimes removes grain or adds unwanted artefacts, giving the image a more "digital" character. Therefore, we mainly recommend it to those who prefer a smoother, less cinematic style of image.

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.

In the category of smearing and motion fluidity, the E7Q PRO has one very strong argument. At this price, Hisense has included a 120 Hz panel, and in PC mode, it can even operate at 144 Hz. This immediately provides greater possibilities in motion settings, as the menu offers more options for smoothing the image. Among other things, we have frame interpolation options, which allow us to adjust the fluidity for sports or films, depending on whether we prefer a more cinematic character or a "theatrical" smoothness.

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.

The E7Q PRO is a phenomenal screen for gamers. Aside from the typical "ache" of Hisense, which is the lack of support for the HGiG format due to permanently active tone mapping, we get practically everything one can expect from a television that is to have a gaming label. There are two HDMI 2.1 ports, along with a full set of key features. We have variable refresh rates, automatic switching to game mode, and support for 4K at 120 Hz. Additionally, all the most important settings are at hand in a clear Game Bar. This tool not only looks modern but also has a typically "gaming" edge and truly makes life easier while gaming.
