Samsung OLED 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 achieve up to 1700 nits in laboratory tests, which is over 500 nits more than the variant with the WOLED panel. This translates to a significantly stronger and more engaging HDR effect. In most scenes, bright parts of the image look fantastic, and we have to admit we were pleasantly surprised because we expected results closer to the WOLED version, but we got an effect that makes a big impression even in movies. As with any OLED, there are moments when the panel has to limit brightness somewhat. This mainly concerns full-screen, very demanding scenes – for example, in the last test frame from the movie "The Meg," brightness drops to around 800 nits. However, it's hard to consider this a flaw since it’s still an excellent result, unprecedented in OLED TVs in this price range. All signs indicate 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 panel in HDR content is its color gamut coverage. Thanks to quantum dots, the television achieves almost full 100% of the DCI-P3 color gamut and nearly 90% of the BT.2020 gamut. These values place it alongside much more expensive models and make it exceptional in its class.

If 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 about 250–300 nits, which is simply too little for HDR to look spectacular. It lacks that "spark" in bright details, flashes, and light effects, and in many HDR scenes, it can resemble better SDR than true cinematic HDR. A consolation in all of this is the colors. We managed to confirm that the E7Q PRO is a PFS type television, meaning it has an additional filter that enhances color gamut coverage. As a result, even if the brightness doesn't deliver, the colors in HDR content can be adequately saturated and pleasant to the eye, without the feeling of a "faded" image.

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

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

Calibration quickly showed that the S90F has a substantial reserve of capabilities. The image in SDR immediately gained a natural quality – classic films stopped looking as if someone had applied a yellowish filter to them, and the colors regained their true character. It’s a return to the atmosphere of the original, without the impression that someone tried to "age" it artificially. 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 after calibration displays an image very close to perfection. Compared to the WOLED version, it performs even better – mainly due to the wider color gamut coverage, which makes the colors look fuller and more vibrant.

In the case of materials with a standard color range (SDR), our efforts in Filmmaker mode turned out to be largely cosmetic 😉. We mainly focused on gentle white balance correction and gamma curve adjustment, which allowed us to recover details in the darker parts of the image that previously tended to get lost. It is worth noting, however, that the E7Q Pro unit we tested happened to be exceptionally well-made from 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 adjustments. The biggest beneficiary of professional calibration was undoubtedly the HDR mode. This is where we did the most work, which yielded spectacular results. We managed to effectively tame the excessive warmth of the image, caused by a factory deficiency of blue color. After calibration, color 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 are repeated in the case of most Samsung TVs. The noise reduction feature can effectively smooth out unwanted color transitions in lower-quality 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 that we wouldn't want to touch, like facial details. Therefore, if we want to use it, it’s best to use it in the "medium" setting and be aware of the compromise it brings. The upscaling itself is at a high level – low-quality materials are enhanced towards a 4K-like image. The only caveat is that the S90F can still have problems with so-called overscan, which is slight trimming of the edges in 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 here and does not fall drastically behind much more expensive, advanced televisions. Lower-quality materials can look clean and sensible, without the impression that the image is artificially "overdrawn." However, the smoothing function presents a bit worse. It can indeed be effective and improve tonal transitions in low-quality materials, but at the same time, it can introduce unwanted effects. Sometimes it removes film grain or adds unwanted artifacts, 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, what matters most is how it performs at 120 Hz, as this frequency is the most significant when watching sports. The QD-OLED panel is no different in this regard from WOLED panels—the pixel response is almost instantaneous, allowing motion to be rendered with surgical precision. The effect is easy to predict. The image is practically free of ghosting, making gaming on consoles, matches, or other sports broadcasts a great pleasure on the S90F.

Fans of movies and series are not forgotten either. Like every Samsung TV with a refresh rate of 120 Hz and above, the S90F is equipped with a proprietary motion smoother called "Image Clarity." Here, we find two sliders—motion blur reduction and judder reduction—that allow you to improve the fluidity of materials recorded at 24 frames and adjust the effect to your personal preferences.

In the category of motion blur and fluidity of movement, the E7Q PRO has one very strong argument. At this price, Hisense has added 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 displays more options for smoothing the image. Among other things, we have frame interpolation options, which allows us to adjust the fluidity for sports or for movies, depending on whether we prefer a more cinematic character or a "theatrical" smoothness.

S90F is a television that truly brings a lot of joy when gaming. Right off the bat, we get four full-fledged HDMI 2.1 ports, which means you can connect all consoles and PCs without having to figure out which device takes priority. This is a convenient and practical solution that is not a given with other manufacturers. Additionally, there are key features such as the automatic game mode (ALLM), which switches the screen to low-latency settings, and VRR frame synchronization working over a wide range from 48 to 144 Hz. This ensures that the picture remains smooth regardless of whether we are playing fast-paced online shooters or calmer story-driven titles. Another noteworthy feature is the Game Bar – a panel that allows quick access to several useful additions. For example, you can turn on an additional crosshair in the center of the screen, enlarge the minimap, or, in the case of a PC, change the aspect ratio. Finally, there is also the unique Game Motion Plus mode exclusive to Samsung. Its purpose is to smooth out older or less optimized titles, and it actually works quite well. Thanks to this mode, even less polished games can look better and provide more enjoyment than on other televisions that theoretically offer the same technical specifications.

The E7Q PRO is a phenomenal screen for gamers. Aside from the typical "thorn" of Hisense, which is the lack of support for the HGiG format due to the constantly active tone mapping, we practically get everything one might expect from a television that is supposed 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. On top of that, all the most important settings are at hand in a clear Game Bar. This tool not only looks modern but also has a distinctly "gaming" edge and actually makes life easier while playing.
