SAMSUNG S90F (WOLED) vs Sony BRAVIA 5 (XR5)

Does the S90F handle not only blacks but also bright parts of the image? Definitely. The stories about OLEDs as "dark screens" can slowly be regarded as myth. The Samsung S90F, like the LG C5 based on a very similar panel, achieves brightness exceeding 1000 nits. This is a value more than enough to enjoy impressive and dynamic HDR images – both in movies and series. Most of the scenes we tested look stunning, with well-defined highlights and high contrast. Of course, OLED technology still has its limitations – in very bright, full-screen sequences, such as the test card from the movie The Meg (photo 5), the television may noticeably dim the image. However, it should be emphasized that such scenes are rare. It can be said that the HDR effect is good enough that even mid-range OLED models like the S90F can provide a cinematic experience in the home living room.

Looking at similar results in terms of black levels and contrast, we expected the same stable performance as last year's model when it comes to HDR content. Unfortunately – and this must be said plainly – there has been a regression here that is hard to miss. The paradox is that the peak brightness of the Bravia 5 can be impressive: in our synthetic tests, the TV reached around 1000 nits in HDR. Sounds great, right? The problem is that this power doesn't always have a real impact on all movie scenes. When small, pinpoint elements appear on the screen, something that in Sony's case was usually fine-tuned with surgical precision, this time it clearly falters. The algorithms try to maintain deep blacks around small objects, but the side effect is that details can be dimmed to the point of becoming barely visible. One only needs to bring up the example of the movie Sicario 2 – there, in some scenes, small light sources practically vanished as if someone had covered them with dark film.

Of course, not everything looks so dramatic. In simpler, brighter scenes, where the image is filled with more light, the Bravia 5 shows that it can shine: literally and figuratively. At those times, the TV achieves values in the range of 600–800 nits, which we saw both in synthetic tests and during movie screenings. The impression is really positive; the brightness adds dynamism, and the colours look vibrant and fresh. However, there remains a certain dissonance. We feel a slight confusion because it is evident that something has gone in the wrong direction. Technological progress – more zones, more backlight power – has not been supported by the kind of refined image management that we usually associate with Sony. Fortunately, there are elements that have not been compromised and are actually at a very high level. We are talking about colour reproduction. Thanks to the use of the PFS filter, the colour palette coverage is excellent – about 97% DCI-P3 and 75% BT.2020. These values allow for a truly wide colour reproduction, giving films a natural and cinematic character.

Samsung S90F, like most modern televisions, offers many picture modes, but – following our testing tradition – we checked it out in the best one, which is the Filmmaker mode. Thanks to this, the image looks much more natural than in the default, often oversaturated settings. It was neither overly saturated nor artificially dimmed – simply closer to what one should see. Of course, “more accurate” doesn’t mean “perfect”. Unfortunately, our S90F had significant issues with white balance, particularly in the blue color range, resulting in a slightly yellowish filter being applied to most scenes. Someone might say it looks more “filmic” – because it’s warmer – but let’s not kid ourselves, George Lucas didn’t film Star Wars in sepia 😉 (you’ll find a comparison with the scene below as always).

Additionally, in HDR materials, there was an issue with brightness management. The EOTF curve showed a clear “spike” in brightness – the television brightened the image more than it should have, causing some effects to look too intense and deviating from the reference. Fortunately, some of these problems can be eliminated through professional calibration – you’ll read about its effects later in the review.

Sony Bravia 5 was obviously tested in the best possible mode, which is the Movie mode. Right out of the box, it delivers the most natural colours, definitely better than anything offered by the "eco" or "dynamic" modes, which are more suited for a store display than a living room. However, the Movie mode alone does not guarantee that we can always expect cinematic picture quality. In SDR content, we had no significant complaints – the slightly warmed white balance gave the scenes a golden hue, but it was nothing that was glaring. However, a problem arose with HDR materials. Here, the colour reproduction simply looked bad. The white balance was heavily skewed – with an excess of blue and a clear lack of red. At times, it resembled the store mode of "super vivid picture," where everything is blown out and artificially boosted.

This situation made brightness management seem too aggressive as well. The EOTF graph clearly showed that the television has trouble with overexposing many scenes right out of the box. And while we know what Sony televisions are usually capable of, it was hard to remain indifferent here – that’s why we quickly decided to go for calibration.

After calibration, we managed to eliminate practically all the previously mentioned errors. Older movies in SDR quality finally look like they should – without the sepia effect or artificial aging of the image. The atmosphere of the classics is back in place (no thanks needed, Star Wars fans), and the colours no longer resemble an Instagram filter.

One of the key changes was also the improvement of brightness characteristics in HDR content. We managed to control the EOTF curve in almost a reference manner. Admittedly, the most demanding users may detect minimal deviations in brightness, but honestly – most viewers won't even notice that. And it's no surprise because the vast majority of errors fall below the ΔE 3 value, which is below the threshold of visibility. After calibration, the S90F (WOLED) becomes a truly excellent display – one on which you can enjoy nearly perfect image quality.

After calibration, the situation changed dramatically. We managed to tune the white balance so that entire scenes began to look more natural, and the image gained coherence and elegance. In HDR, we finally got rid of that unwanted clipping effect that had previously spoiled some shots. Suddenly, it turned out that the Bravia 5 can extract much more from films than the first contact "straight out of the box" suggested. Indeed, if we look at the graphs and compare them with the standards, we can see that the beginning of the EOTF curve slightly strays beyond the reference line. However, this is not so much a calibration error as it is a natural limitation of the Mini-LED technology that cannot be bypassed. Sony, rather than clinging tightly to perfect black, prefers to prioritise the visibility of details – and in practice, it’s hard to disagree with that. We prefer to see the texture of the material on the screen rather than a pitch-black spot where all nuances disappear.

The calibration itself was really beneficial. After about an hour spent on settings, we felt that the image resembled that of the best cinema halls – of course on a home scale, but with the same sense of quality and refinement. And in such moments, we remember why we love Sony televisions: because once we fine-tune them, they reward us with a picture that captivates for long hours.

Digital Image Processing in S90F:

Fortunately, Samsung, like in most of its models, manages to effectively tackle the unwanted posterisation effect in the S90F. The function responsible for this element is noise reduction, which does a pretty good job of smoothing tonal transitions and eliminating unnatural colour blending – of course, within its capabilities. Unfortunately, it works quite aggressively, so using it comes with trade-offs. In addition to improving gradation, it can also remove film grain or slightly soften facial features. In this case, the choice is yours – do you prefer a more "clean" image, or do you care about preserving the original texture of the material.

Image Scaling in S90F:

In this year's model, Samsung has implemented its proprietary AI processor – NQ4 Gen3, which really handles upscaling quite well. In our test scenes, the TV effectively "pulled up" lower quality towards artificial 4K – the image was more enjoyable to view, and the differences in sharpness between native and scaled content were minimal. Unfortunately, behind all this AI marketing façade lies a certain shortcoming. The S90F struggles with overscan. If you reach for truly archival material – e.g. a VHS tape of your parents' wedding – you have to reckon with the fact that the lower part of the image may get cut off. The function to adapt the image to resolution simply does not work as it should here.

Bravia 5 carries the genes of Sony, which remain intact – and thank goodness for that, because we're talking about absolutely exceptional digital image processing. It's no coincidence that for years, it's been considered that TVs from this brand set the standard for how a screen should handle lower quality materials. If someone still watches classic television, old films, or YouTube in lower resolutions, here they get equipment that can turn such content into a surprisingly enjoyable experience. On board, we find several tools worth activating. The first of these is "digital noise reduction." Set to a medium level, it works superbly – smoothing out tonal transitions that usually cause the most trouble in low-quality materials while introducing no artificial artifacts. Importantly, it also doesn't remove the cinematic character, which is the natural grain that is intentionally present in many productions. Another advantage of the Bravia 5 is the upscaling capabilities of the XR processor. The image presented after scaling is soft, yet sharp and clear. The outlines of characters are well-defined, and backgrounds maintain their texture without excessive artificial sharpening. It's hard to find a better TV for watching lower quality materials – Bravia 5 only confirms why Sony is considered the benchmark in this area.

S90F really handles motion excellently – after all, it’s an OLED with a 144 Hz panel, so sports and games look absolutely stunning on it. The image is smooth, clear, and there’s no room for ghosting or blurring, which can sometimes plague cheaper LCDs.

The TV also comes equipped with motion smoothness settings that allow you to customise everything to your liking. We have motion blur reduction and judder reduction – you can set it so that the image is super smooth (even to the point of looking a bit soap opera-like), or more cinematic, with the classic “jumpiness” of 24 frames. The choice is yours, Samsung imposes nothing.

Bravia 5 has a 120 Hz panel, which in itself sounds like an invitation to watch sports, fast matches or spectacular action films. However, the real magic begins when MotionFlow – Sony's proprietary motion smoother – comes into play. Thanks to this feature, we can adjust the character of the picture to our own preferences. The "smoothness" slider allows us to transition from a cinematic feel with a slight "judder" to a theatrical fluidity, where every ball in the match glides across the screen as if on a string. The higher the value, the smoother and more fluid it is; the lower it is, the more film-like and natural it becomes. In the options, we also find an additional setting that Sony calls "clarity". This is nothing more than the BFI function (which inserts black frames) aimed at improving motion sharpness. It sounds great in theory, but in practice, it must be used with caution. Why? Because all higher settings cause brightness drops of up to half, and in some cases, contour doubling also appears. So if we want to use it, we recommend setting it to the lowest level – "1" out of the available ten. That way, we gain a bit better motion sharpness without risking losing half the brightness of the picture.

When it comes to gaming features – the S90F has absolutely nothing to complain about. Aside from the lack of Dolby Vision, which is already the norm for Samsung. The television operates at 144 Hz, has four HDMI 2.1 ports, so you can easily connect more than one console or PC. Onboard, we also find Game Bar – a practical tool that allows you to quickly preview picture settings, VRR status, ALLM mode, and other useful options. Game Motion Plus deserves special mention – Samsung's proprietary motion smoother that actually works sensibly in games. The image appears smoother, but without any artificial effects or slowdowns.

It's also worth mentioning the HGiG feature, which – and this may be a slight surprise – works correctly. We bring this up because Samsung clearly messed something up in one of the recent updates, and in some models, the option responsible for HGiG simply... disappears from the menu. Setting it up becomes almost impossible. Fortunately, our S90F unit did not have this issue, but the situation is dynamic, so it's worth keeping this in mind and regularly checking for new software versions and information from the manufacturer.

In the Bravia 5, there is a significant improvement compared to the X90L model from two years ago. The television offers literally everything its predecessor had, but this time the issues that could frustrate gamers have been addressed. Problems with setting the variable refresh rate (VRR) have disappeared, and there are no longer issues with configuring HDR content in HGiG mode. In short: we get a device that simply works as it should, without any hassles. So, the Bravia 5 has everything you can expect from a modern gaming TV – and it can be confidently advertised with the slogan "ready for PS5." That's something we couldn't say about the X90L model. Well done, Sony!

It's just a shame that this relatively high-priced model lacks a full set of four HDMI 2.1 ports. In everyday use, this won’t be an issue for most people, but if someone has a console, soundbar, and additional equipment connected via HDMI, at some point they'll have to choose or juggle cables.
