Samsung S90F QD-OLED vs Hisense E7Q PRO / E79Q PRO

The biggest difference between the 65-inch S90F and the other versions is brightness. The QD-OLED panel can reach up to 1700 nits in laboratory tests, which is over 500 nits more than the variant with a WOLED matrix. This translates to a decidedly stronger and more engaging HDR effect. In most scenes, bright parts of the image look fantastic, and we must admit that we were positively surprised, as we expected results more similar to the WOLED version, but we got an effect that makes a great impression even in films. Just like with every OLED, there are moments when the panel needs to limit its brightness a bit. This mainly refers to full-screen, very demanding scenes – for example, in the last test frame from the film "The Meg," the brightness drops to around 800 nits. However, it is hard to consider this a disadvantage, as it is still an excellent result, unprecedented in OLED televisions in this price range. Everything suggests that the 65-inch S90F could be one of the best choices this year for those looking for a strong OLED at a reasonable price. Another advantage of the QD-OLED matrix in HDR content is its colour gamut coverage. Thanks to quantum dots, the television achieves almost a full 100% of the DCI-P3 colour space and nearly 90% of the BT.2020 colour space. These values place it alongside much more expensive models and make it exceptional in its class.

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.

Samsung S90F, like most modern televisions, offers several picture modes, but in line with our tradition, we tested it in the most important one, which is Filmmaker. This setting makes the image look much more natural than in the default, often overly saturated modes. It is neither excessively vivid nor artificially subdued – just closer to what one should actually see. However, this does not mean it is perfect. The S90F had noticeable shortcomings in white balance, mainly in the blue range, which gave a slightly yellowish filter effect on most scenes. One might argue that it looks more "filmic" because it is warmer, but let’s not kid ourselves – George Lucas didn't shoot Star Wars in sepia 😉 (a comparison with the scene can be found, as always, below). In HDR materials, there was also an issue with brightness management. The EOTF curve clearly showed that the television brightens the picture more than it should, leading to some effects appearing too intense and deviating from the reference. Fortunately, a large part of these shortcomings can be eliminated through professional calibration – we will discuss the effects of this procedure further on in the test.

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.

Calibration quickly revealed that the S90F has a significant margin of capability. The image in SDR immediately gained a natural quality – classic films no longer looked as if someone had applied a yellowish filter to them, and the colours regained their proper character. It is a return to the atmosphere of the original, without the impression that someone tried to "age" it forcefully. In HDR content, the difference was even more pronounced. The EOTF curve was managed almost to a reference level, and any deviations are so subtle that most viewers won't even notice them. In practice, the S90F shows an image very close to perfection after calibration. Compared to the WOLED version, it performs even better – mainly due to the wider colour gamut coverage, which makes the colours appear fuller and more intense.

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.

The S90F performs really well here, although there are some comments that recur with most Samsung televisions. The noise reduction feature can effectively smooth out unwanted colour transitions in poorer materials, such as television or YouTube, making them simply look better. However, it should be noted that it operates quite aggressively and can also soften elements we wouldn't want to touch, like facial details. Therefore, if we want to use it, it’s best to set it to 'medium' and be aware of the compromise it entails. The upscaling itself is at a high level – low-quality materials are upscaled towards a 4K-like image. The only caveat is that the S90F can still struggle with so-called overscan, meaning it slightly trims edges with very poor materials like 576p and lower.

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.

S90F is an OLED with a refresh rate of 144 Hz, but in practice, it primarily indicates how it performs at 120 Hz, as this frequency is most significant when watching sports. The QD-OLED panel is no different in this regard from WOLED panels – the response of the pixels is nearly instantaneous, so motion is rendered with surgical precision. The result is predictable. The image is virtually devoid of motion blur, making gaming on consoles, matches, or other sports broadcasts incredibly enjoyable on the S90F.

Fans of films and series have not been overlooked either. Like every Samsung television with a refresh rate of 120 Hz and above, the S90F features a proprietary motion smoothing technology called "Image Clarity." Here, we find two sliders – blur reduction and judder reduction – which allow for improved fluidity of materials recorded at 24 frames and tailoring the effect to personal preferences.

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 S90F is a television that truly brings a lot of joy when gaming. To start, we have four full-fledged HDMI 2.1 ports, which means you can connect all consoles and PCs without worrying about which device has priority. This is a convenient and practical solution that is by no means a given with other manufacturers. Additionally, there are key features such as automatic game mode (ALLM), which automatically switches the screen to low-latency settings, and VRR frame synchronization that operates in a wide range from 48 to 144 Hz. As a result, the picture remains smooth regardless of whether we're playing fast-paced online shooters or more leisurely narrative titles. The Game Bar also deserves a mention – a panel that allows quick access to several useful additions. For example, you can enable an additional crosshair in the centre of the screen, enlarge the minimap, or, in the case of PC, change the aspect ratio. Lastly, there is also the unique Game Motion Plus mode from Samsung. Its purpose is to smooth out older or poorly optimized titles, and it actually works pretty well. Thanks to this mode, even less polished games can look better and provide a more enjoyable gaming experience than on other televisions that theoretically offer the same technical specifications.

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.
