Samsung S90H (QD-OLED) vs Samsung The Frame Pro 2026 (LS03HW)

The Samsung S90H is a genuinely bright TV for the mid-range OLED segment. In synthetic tests its peak brightness reached around 1650 nits. That’s an impressive result in this class, roughly 50% higher than what we have seen from previous models in this price bracket. Most importantly, these tests translate directly to real video material. In four out of five film clips we tested, the S90H’s brightness ranged between 1300 and 1500 nits. That headroom allows it to reproduce most HDR films with very high dynamic range and without obvious compromises, especially in material mastered to 1000–1500 nits. In practice light effects, reflections and explosions have the appropriate punch, and the picture does not appear dimmed. Of course, on full-screen very bright scenes the result is naturally lower and drops to around 900 nits. This is a direct result of the OLED panel’s protection systems working to prevent overload. Even in this scenario there is little to complain about. Those 900 nits across the whole screen is still a very high level, ensuring excellent dynamic range in HDR content.

Colour has always been a major strength of QD-OLED TVs, and the S90H is no exception. The DCI-P3 colour space we measured reached a full 100% (actually 99.9%), while coverage of the much wider BT.2020 gamut hit about 89%. That’s an excellent result, enabling very saturated and vivid colours in HDR content. It’s worth emphasising that QD-OLED’s advantage over WOLED panels is not limited to palette coverage alone. In practice it’s mainly visible in the higher brightness of saturated colours, that is in a greater colour volume. As a result, intense reds, greens and blues in HDR look more vibrant and more striking.

One thing you cannot deny The Frame Pro is: brightness. At peak we measured around 850–900 nits, so the TV already has enough power to show many HDR scenes really impressively. Bright, full‑screen shots and more colourful frames perform best here. In such scenes The Frame Pro can make a good impression because the image is bright, punchy and has the effect we expect from HDR. In our measurements some scenes reached over 800 nits, and even in more challenging segments the TV maintained a quite respectable brightness level.

The problem starts when HDR depends on small bright elements shown on a dark background. Individual lamps, stars or highlights can be bright, but very often the black level across a larger part of the image also rises. As a result the bright point itself may look good, but the whole frame loses a lot of quality. Therefore The Frame Pro shows HDR best in scenes that are simply full‑screen. If a film or TV series has plenty of such shots, the effect can be really pleasant. In darker material the limitations of local dimming are much more noticeable.

Colours

The Frame Pro should be praised for its colour gamut coverage. The TV uses quantum dots, the solution known as QLED, which allows it to reproduce very well saturated colours. In our measurements coverage of the most important film gamut DCI‑P3 was around 94.5%, while the more demanding BT.2020 was about 72%.

These are very solid results that in most scenes allow for pleasant, saturated colours. Of course these figures are not as spectacular as in the latest screens using RGB backlighting, but The Frame Pro makes up for that with something else: colour stability. Regardless of the scene, colour saturation remains fairly consistent and there are no situations where the TV loses colour badly in more demanding shots.

The next stage of the test was to check how the S90H handles colour reproduction without any calibration. As always, we carried out the measurements in Filmmaker Mode, the best factory picture preset. And here Samsung really deserves praise. The factory tuning is at a very high level, and a few years ago this was not one of its strong points. The average colour error (Delta E) remained around 3, which is below the level at which most people can notice any inaccuracies. Only in the brightest shades of grey did the values slightly approach 4, but even then it's hard to regard this as a real problem while watching. For out-of-the-box settings, the result is simply excellent.

In SDR material The Frame Pro in Filmmaker mode performs quite well, though it falls a little short of perfect. The white balance is relatively even, but as brightness increases the blue component drops, so the brighter parts of the image can have a slightly warmer tint. A bigger difference is visible in the gamma, that is the handling of the screen's brightness. For most of the range it runs below our reference point, which means the TV slightly brightens midtones. As a result the image can appear a little brighter and less contrasty than it should. The colour errors themselves are not huge, but they are noticeable enough that calibration could still bring considerable improvement.

In HDR content the white balance looks similar — for a large part of the range it is fairly even, with larger deviations appearing only at higher brightness. The EOTF curve is more interesting. The Frame Pro sticks reasonably close to the reference values in the brighter part of the image, but clearly brightens the darkest sections. This is mainly due to the design of the TV's backlight. That also affects colours. With less saturated hues the errors remain moderate, but as saturation increases they become much larger. In Colour Checker measurements a large portion of samples already show high error values. The factory HDR can therefore be regarded as decent, but it is certainly not an image we would call very faithful.

All right, but you know we wouldn't be ourselves if we didn't also check how far we could push the S90H after professional calibration. And there was no big surprise. Since the factory settings were already very good, there wasn't much room for improvement. Even so, we managed to refine the picture to near perfection. After calibration the mean colour reproduction errors fell below the threshold of perception, with Delta E values under 2 for both SDR and HDR material. We also improved the brightness response, so the image more faithfully reflects the creators' intent and maintains appropriate tonality across the whole luminance range. After professional calibration the S90H therefore becomes a display very close to reference.

Will the difference be spectacular for everyone? Not necessarily. The factory settings already deliver a very high level, so in everyday viewing some people may not notice a dramatic jump. Much also depends on the individual unit. Our sample was very well tuned straight out of the box, but that doesn't mean every S90H will perform at the same level. Even identical models can differ from each other in terms of factory calibration. That's exactly why professional calibration makes sense: it allows a specific unit to be brought to the highest possible accuracy, rather than relying on a bit of luck when buying.

After calibration the biggest improvement is visible above all in SDR content. We managed to even out the white balance, but the more important change was the gamma correction, which before calibration had the greatest influence on the image character. After the adjustments the gamma curve is now very close to the reference, so the picture is not as bright in the midtones and simply looks more natural. Colour errors have also been significantly reduced, so the effect of calibration in SDR is clearly visible.

With HDR the situation is somewhat more complex. White balance has been improved and over part of the range the TV stays much closer to the reference, but deviations still appear at higher brightness levels. The same applies to colour reproduction: some errors can be corrected, but not all stem from the settings alone. This highlights the limitations of the TV's design and the way its backlight and local dimming affect HDR images. Therefore, with The Frame Pro calibration makes the biggest difference to everyday viewing. Regular TV, YouTube and films and series in SDR (mainly those from the cheaper tiers of streaming services) can look noticeably better afterwards.

In this respect Samsung has changed practically nothing compared with last year’s model, which is actually quite good news. The feature responsible for smoothing tonal transitions still very effectively limits the posterisation effect. However, you should remember that it works rather aggressively, because besides the artefacts themselves it can also remove film grain and slightly soften fine image detail. As always, this is therefore a matter of compromise and personal preference. If you want the most faithful reproduction of the source material possible, we recommend leaving this function turned off.

There is also little to be said about upscaling in terms of revolution. The S90H uses the same proprietary NQ4 Gen3 image processor as its predecessor, so scaling quality has remained practically unchanged. The TV handles lower-resolution material well, effectively improving its sharpness. However, the overscan problem has still not been solved. With some older material, especially archival recordings, it may happen that a portion of the image at the edges is cropped. It’s a minor flaw, but a shame Samsung has left this issue unchanged for another year running.

The Frame Pro uses the NQ4 AI Gen3 processor, so in terms of image processing it behaves very similarly to other newer Samsung TVs. Upscaling works really well – lower-resolution content is appropriately sharpened and the picture remains clear without excessive edge enhancement. With regular broadcast TV or lower-quality YouTube material this can provide a noticeable improvement, although viewers watching even older material, e.g. from VHS tapes, may notice a slight cropping of the image on the left side (overscan).

It's a bit different when improving more highly compressed footage by reducing noise and artefacts such as posterization. The "Noise reduction" function can improve poor material, but fairly quickly it begins to alter the picture and remove fine details and grain. Therefore it's best to use it sparingly and mainly when the source truly requires it.

In terms of motion handling the S90H delivers a very high level. A new feature here is a panel with a refresh rate of up to 165 Hz, although in practice that will mainly benefit PC gamers. Films, series and sports broadcasts do not use such high refresh rates, so when watching them the difference compared with the standard 120 Hz will not be noticeable. That said, thanks to the OLED panel's lightning-fast response time motion is very clean and the picture does not suffer from the motion blur typical of many LCDs. Samsung has equipped the television with extensive motion-smoothness settings. You get two sliders: judder reduction and blur reduction, which let you easily tailor the picture's character to your own preferences. You can easily achieve a very smooth image when watching sport, but you can just as well preserve a more cinematic feel at the typical 24 frames per second. It all depends on which effect you prefer.

The Frame Pro comes with a 144 Hz panel, and when connected to a PC it also supports 240 Hz at Full HD resolution. That feature is primarily aimed at PC gamers, but the TV also performs very well at the standard 120 Hz refresh rate used for watching sport or gaming on consoles. A key advantage is the low level of motion blur. For a VA panel, The Frame Pro does very well in this respect. You don't see the strong, dark trailing smears behind moving objects that we often encounter on TVs with this type of panel. As a result, fast-paced sport and dynamic games remain clear in motion. Of course there's also motion smoothing with adjustable smoothness, so for films and sports broadcasts we can tailor the motion character to our preferences. You'll find our recommended settings in the photo.

From the outset the Samsung S90H feels like a TV designed with gamers in mind, and it's easy to see why. The manufacturer has equipped it with almost everything you could expect from a modern gaming screen. You get as many as four full-bandwidth HDMI 2.1 ports, support for ALLM and VRR, and very high refresh rates. There's also a clear Game Bar that lets you instantly check key picture parameters or change settings without leaving the game. Another very welcome improvement is the HGiG behaviour. Last year it could cause quite a few problems, but on the S90H it works exactly as it should.

Samsung's ace up its sleeve remains its proprietary Game Motion Plus mode. The feature works similarly to the motion smoothing used for films: it improves animation smoothness in games while keeping input lag at a very reasonable level. For titles running at 30 or 60 fps, with the right settings input lag did not exceed 40 ms in our tests. That's a very good result, especially since with many manufacturers enabling similar features results in delays several times higher. Game Motion Plus does not, of course, replace Dolby Vision Gaming, as it's a completely different type of feature, but overall it's a gaming addition that many players may find more noticeable. Smoother motion in 30/60 fps games often makes a bigger difference than HDR itself (which, incidentally, is often poorly implemented in games).

Functionally for gamers The Frame Pro has a great deal to offer. The TV supports 4K at 120 Hz, VRR, ALLM and a properly implemented HGiG. When connected to a PC you can also use 144 Hz at 4K, and even 240 Hz when dropping to Full HD. Samsung also includes its standard suite of gaming extras. There is an expanded Game Bar that lets you quickly view and change the most important settings, and Game Motion Plus, which can improve the smoothness of games running at 30 or 60 frames per second. On top of that there is the Gaming Hub and the option to play in the cloud without needing to connect a console. The only real omission is Dolby Vision Gaming, which Samsung does not support. Apart from that, The Frame Pro offers virtually everything you can expect from a well-equipped gaming TV today.
