Panasonic W85 vs Samsung OLED S90F (QD-OLED)

Unfortunately, we don't have good news here. The Panasonic W85B is rather dim – its peak brightness does not exceed 300 nits, so it's hard to talk about any true HDR effect. In practice, this means that scenes which on other screens can "shine" and make an impression, here look simply like regular SDR with a slight boost in colors. Our measurements and film tests confirmed this – regardless of the content, the W85B won't extract anything more from HDR. So if someone is looking for a TV specifically for HDR, it's better to look towards other models. As a consolation, the fact remains that in terms of colors, the W85B performs quite well. It's a QLED TV, so its color gamut coverage is wide, and most films and series look natural, without a distinct "washed out" effect. The colors are saturated, so during regular viewing, there is no sense that something is quite wrong.

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.

While testing the Panasonic W85B, we of course started with the Filmmaker mode, as it is the gold standard today for watching content "as the director intended." The problem is that this TV is quite far from those intentions. The biggest issue turned out to be an excess of red – in both SDR and HDR. The picture often looked overly warm, and in some scenes, it appeared almost "blazing." Additionally, there’s the issue of brightness management. When we looked at the gamma and EOTF charts, it was clear as day that in most scenes, the TV brightens the image more than it should. The effect was easy to predict. Details can get lost, leading to flattening and clipping across the entire screen. Of course, we know how to improve this, but it must be said honestly that it requires quite a bit of work in calibration. Out of the box, the W85B does not provide a reference-level picture – it is rather a TV that will always interpret colors and brightness a bit "its own way" without professional adjustments. Unfortunately, this is to the detriment of the viewer.

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.

Fortunately, calibration made a significant difference for the Panasonic W85B, especially in SDR content. Here, the improvement was really noticeable – we managed to balance the white and reasonably tame the TV's tendency to excessively brighten the entire image. The picture became more coherent, and the colors gained a naturalness that was lacking in the factory settings. Admittedly, the results from the Color Checker are not perfect, as the W85B has visible issues with green saturation, but overall, we assess the post-calibration effect in SDR very positively. The situation with HDR is a bit different. Here, we were also able to limit the tendency to warm up the entire scene, so the image turned out much better than in the factory settings. However, the same problem we mentioned earlier is still evident – the TV interprets the image too "in its own way" and brightens the entire frame. The lack of local dimming only exacerbates this effect. In summary, briefly in SDR content, the W85B performs really well after calibration and is perfectly suitable for everyday viewing. However, in HDR, even after adjustments, it is still hard to unequivocally recommend it for serious viewing sessions.

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.

With native SDR content, the Panasonic W85B performs very well – tonal transitions are smooth and natural, without artificial bands or clear contours. However, the situation looks worse with lower resolution materials. This is where the television has the biggest problem with "beautifying" the image. The lack of any option in the menu that would allow for improving gradation means that with older films or materials from YouTube, one can sometimes notice slight issues with color blending.

Fortunately, upscaling, or increasing the quality of lower resolution content, performs much better. This is definitely a strong point of this model – the image is scaled cleanly and in detail, and the television handles this better than one might expect from such an affordable device. This is thanks to the HCX processor, which Panasonic has been developing for years, and it shows that even in the lower series, it can do a good job.

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.

At first glance, everything looks good – the Panasonic W85B has a 120 Hz panel and even a 144 Hz mode, so it seems that it should handle smooth motion well. The problem begins when we look into the settings. The options for improving fluidity are supposedly present in the menu, but in practice… they change nothing. No matter what we choose, the image looks the same. On top of that, there's a lack of BFI, which is the black frame insertion mode that helps sharpen motion in many TVs. And suddenly, it turns out that despite having a strong panel, the W85B doesn't give us any real tools to adjust that motion to our needs. It only works well when the source itself operates at a higher frequency – for example, games at 120 Hz. But when it comes to movies or sports, we just have to take what the TV shows us, because there's nothing more we can do about it.

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.

On paper, the Panasonic W85B looks really solid. Here we have two full HDMI 2.1 ports, support for ALLM, variable refresh rate, Dolby Vision in games, and of course, a high refresh rate for the panel itself. Additionally, there’s the characteristic Panasonic game bar that allows you to check key parameters with one click and quickly change them if necessary. Sounds great, but the problem arises when we activate HDR. Here, the W85B significantly falters because it lacks proper HGiG implementation – the TV manages brightness poorly, and instead of faithful image rendering, we get scenes that are too bright, sometimes even blown out. The solution? The simplest – turn off HDR in the console settings and leave everything in SDR. And here it gets really interesting, because in this scenario, the W85B shows its better side. Low input lag, high smoothness thanks to 120 Hz – all of this makes gaming look phenomenal. Yes, HDR can be sacrificed, but if responsiveness and smooth gameplay are priorities, the W85B provides a lot of fun.

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.
