Panasonic Z95B vs Samsung S90F QD-OLED

The quality of HDR on the Panasonic Z95B is among the absolute best. Thanks to the latest generation panel, referred to by the manufacturer as Primary RGB Tandem OLED, the television can achieve over 2000 nits of brightness in cinematic scenes. The effect is impressive and can amaze with the intensity of the light, providing a sense of connection with the screen that goes beyond previous experiences. Similar feelings accompanied us only during tests of the LG G5, Samsung S95F, or Philips OLED910. Of course, there are moments when the device's algorithms decide to limit luminance – this especially concerns full-screen bright sequences, such as the closing credits in the film The Meg. Even then, the Z95B maintains a level of around 1500 nits, which is still an incredibly impressive result. One can thus say that HDR in this model has reached masterful form. A significant step forward is also evident in colour reproduction. The new tandem OLED panel does not yet match the best QD-OLED screens in terms of full gamut coverage, but the gap between these solutions has significantly decreased. When watching films, the differences are subtle enough that under normal conditions they are hard to notice, and the colours remain vivid and saturated.

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.

The factory colour reproduction of the Filmmaker mode, my dear friends, is truly remarkable in the case of the Panasonic Z95B. I'm referring to our test sample, but the result was so good that it’s hard to believe. The only detail one might nitpick about is a slight lack of blue in the white balance, but apart from that, the television straight out of the box presented an image unlike anything we have ever seen in factory mode. Tests of the colour palette, Color Checker – everything indicated values below Delta 2. That’s a much lower result than the threshold of human eye perception, which means, quite simply, that the viewer has no chance of noticing any serious deviations. It looks as though Panasonic has actually calibrated this model at the factory stage. Of course, we cannot rule out the possibility that we received an exceptionally well-set sample, but the result is still impressive. We are very strict when it comes to evaluating factory calibration, and here our jaws simply dropped.

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.

The colour representation after calibration in the Z95B is a topic that is difficult to elaborate on, as there was simply not much to be done here. A slight adjustment of the white balance was sufficient to eliminate the lack of blue, and at this point, the picture reached an almost reference level. It must be admitted that we haven't had such a small range of work in a while. If any of you are particularly observant, you may notice minimal deviations in the EOTF curve, but this is rather related to the operation of the dynamic tone mapping function we mentioned earlier. In fact, it is not a flaw, but a characteristic of this solution, which deliberately alters the brightness characteristics depending on the scene. In summary, we are extremely impressed. The Panasonic Z95B is a television that looks great straight out of the box, and after calibration, it reaches a level where it is truly difficult for us to find anything to improve.

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.

Let’s start with what works well. The upscaling on the Z95B is at a very high level – the picture in lower resolutions is clear and sharp, and the only minor drawbacks are subtle aliasing in certain areas of the image. It’s also important that the television does not crop the material in any way and maintains its proportions, which is not always an obvious fact even in 2025.

The situation with digital processing is less impressive. Features such as “gradation smoothing” or “block noise reduction” practically do not work – the material tested looked identical regardless of the settings. We might as well state that this feature simply does not exist. This is somewhat disappointing, especially since Panasonic heavily promotes its HCX Pro AI II processor, boasting the presence of artificial intelligence to enhance picture quality. Meanwhile, in such a basic area, the television does not provide a real effect and it appears weaker than one might expect from high-end equipment.

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.

The OLED matrix with a very high refresh rate already provides an extremely sharp image even in dynamic sports scenes, such as football or basketball matches, and the Z95B is no exception. It is also very important that the television is equipped with an proprietary motion smoothing system called “Intelligent Frame Creation”. Among the available sliders, the most important one is the one named “film smoothness”, as it allows you to adjust motion to your own preferences when watching 24-frame materials, i.e. films – from a more “frame-like” appearance to a smooth, almost theatrical effect. It is somewhat disappointing that Panasonic did not choose to overclock the latest OLED matrix to 165 Hz, as Samsung did with the S95F or LG with the G5, because we know that the panel is technically capable of it. On the other hand, this is mainly an advantage for PC gamers, so in everyday viewing, it is not a significant drawback since we are limited to 120Hz.

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.

The Panasonic Z95B is fully equipped for gaming. Two HDMI 2.1 ports with full bandwidth of 48 Gb/s guarantee support for everything you would expect from a modern screen. There is VRR frame synchronization, an automatic ALLM game mode, and full compatibility with HDR formats used in games. The television supports both Dolby Vision for Xbox and the popular HGiG, which has been implemented correctly in this case, so it actually works as it should.

Although the brand is mainly associated with home cinema and equipment for filmmakers, there is also room here for features for gamers. On board, there is a Game Bar (or rather Game Circles) – visually, it looks a bit unusual, but it serves its purpose and allows you to quickly check the most important picture parameters. The only thing that is actually missing for complete happiness is having four HDMI 2.1 ports instead of two. It's a minor detail, but in a television of this class, one could expect a full set.

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.
