Samsung S90F 65-inch: Two-minute review

The Samsung 65S90F TV I tested features the brand’s quantum dot approach to OLED technology. It doesn’t push the brightness of this relatively new take on the best OLED TV tech as hard as the flagship Samsung S95F OLED TV does, but that doesn’t stop it from delivering a big improvement over last year’s Samsung S90D – a level of improvement that makes it arguably the most all-round attractive TV in Samsung’s 2025 TV range once you’ve taken value into account.

Movie fans will be in awe at the Samsung 65S90F’s phenomenal contrast and light control, which finds stunningly deep black levels (provided you’re not shining some sort of spotlight at the screen…) balanced with highlights that hit levels of intensity we once thought OLED would never achieve.

Samsung’s approach to OLED technology also helps the 65S90F deliver incredibly vivid colors, while its latest NQ4 AI Gen3 Processor ensures that there’s much more subtlety and nuance in the way these fantastically rich tones are used to create more natural, three-dimensional pictures than its already illustrious predecessor managed.

Gamers are in for a treat with the 65S90F too, as it delivers such console and PC-friendly features as support for 4K at up to 144Hz, variable refresh rates across all four of its HDMI 2.1 ports, and one of the fastest response times I've ever seen from a TV.

Its Tizen smart system is packed with content and increasingly easy to use, too, and notwithstanding the occasional bass fumble, the 65S90F even manages to sound good despite its ultra-slim design.

Add to all this the fact that the 65-inch S90F costs hundreds less than its flagship S95F sibling, and it starts to become seriously hard to resist. But let me point out that this review and the performance figures only apply to the 65-inch version – at other sizes, instead of a QD-OLED panel, you may get a W-OLED panel, with different performance.

Samsung S90F series: Prices and release date

• Release date: April 2025
• 42-inch: $1,299 / £N/A / AU$1,799
• 48-inch: $1,499 / £1,499 / AU$2,499
• 55-inch: $1,799 / £1,899 / AU$3,299
• 65-inch: $2,499 / £2,699 / AU$4,299
• 77-inch: $3,499 / £3,799 / AU$5,999
• 83-inch: $5,399 / £5,999/ AU$7,999

The 65-inch S90F was released worldwide during April 2025. It sits in the second tier of Samsung’s 2025 OLED TV range, below the significantly brighter and more expensive S95F flagship series.

Its $2,499 / £2,699 / AU$4,299 pricing places it right at the heart of today’s upper mid-range TV marketplace, and pitches it squarely against such key rivals as the LG C5 and Samsung’s premium mini-LED TV for 2025, the Samsung QN90F.

The sizes above are the official prices for the other options in the S90F model range, but again, we're only focusing on the 65-inch here.

Samsung S90F 65-inch review: Features

• 4K quantum dot OLED TV
• HDR10, HLG and HDR10+ HDR support
• Gaming support up to 4K 144Hz with VRR

For many AV fans, the 65S90F’s key appeal will be getting Samsung’s QD-OLED technology for substantially less money than the brand’s S95F flagship OLED costs.

The attraction of QD-OLED technology is that it delivers red, green and blue colors without the additional white element used by traditional OLED screens, yet still manages to at least match those ‘WRGB’ OLEDs when it comes to high dynamic range-friendly brightness for video and gaming content.

The tech has already delivered some truly spectacular picture quality results since Samsung first launched the technology back in 2022, including multiple TV of the Year award-winners.

Samsung claims to have improved the performance of the 65S90F over its S90D predecessor with increased brightness and more granular control of its QD-OLED panel, as well as an upgraded NQ4 AI Gen 3 processor.

This is stated to run NPU and GPUs that are twice as fast as the ones used in Samsung’s step-down S85F OLEDs, as well as a 17% faster CPU, while introducing new AI-driven picture and sound elements on the back of a 6.4 times increase in the number of neural networks the TV carries.

The 65S90F’s sound also benefits from Samsung’s OTS technology, which, despite the TV only having a 2.1-channel speaker configuration, uses clever audio processing to try and make sounds appear to be coming from the correct part of the screen. Or even the precise area beyond the screen’s edges if that’s what an audio mix dictates.

If you partner the 65S90F with a Samsung soundbar, you get the additional advantage of Samsung’s Q-Symphony feature, where the speakers in the TV join forces with those in the soundbar (rather than being replaced by them) to deliver a larger center channel sound with more accurate detail placement.

The 65S90F’s connections are outstanding for a mid-range TV, dominated as they are by a set of four HDMI ports that are all built to cope with the latest gaming features of 4K 120Hz feeds (actually 4K 144Hz is supported via Samsung’s Motion Xcelerator technology), variable refresh rates (including both AMD FreeSync Premium Pro and Nvidia G-Sync, with the latter coming in a software update), and auto game mode switching.

All of that is backed up by both a dedicated gaming hub within the TV’s Tizen operating system and a specific game monitoring and adjustment menu, but more on this later.

As ever with Samsung TVs, the 65S90F’s HDR support includes the ‘core’ HDR10 and HLG formats, as well as the premium HDR10+ system that adds extra scene-by-scene image data to help compatible displays deliver more accurate and punchy results.

This HDR10+ support extends to the Adaptive version that can adjust its output to compensate for ambient light conditions, and HDR10+ gaming.

Samsung continues, though, not to support the Dolby Vision HDR format on its TVs.

One other thing the 65S90F does not have is one of the potent anti-glare screen filters sported by Samsung’s S95F flagship OLED TVs and some of its 2025 premium LCD TVs.

That doesn’t mean the 65S90F’s screen is so reflective that it often or severely gets between you and the TV’s outstanding picture quality in a regular living room set up, though. And while I personally have a lot of time for Samsung’s anti-glare TV filters, some people actually prefer a slightly glossy screen, and for those people, the 65S90F is therefore a potentially great QD-OLED alternative to the S95F.

Samsung S90F 65-inch review: Picture quality

• Exceptional contrast
• Rich, pure RGB colors
• No viewing angle limitations

Despite not being the flagship 65-inch model from Samsung’s 2025 OLED range, the 65S90F still delivers a gorgeously potent demonstration of what the latest QD-OLED panels are capable of.

Its light control and contrast are particularly phenomenal. The ability of each pixel in any OLED screen to deliver its own brightness and color entirely independently of its neighbors always gives OLED TVs an instant and important area of advantage with home theater fans, of course – but for the vast majority of the time the 65S90F manages to combine the sort of phenomenally inky, deep black tones expected of OLED TVs with brighter HDR image highlights than its S90D predecessor managed.

And that’s while also revealing substantially more consistently visible shadow detail in the darkest image corners – it's better in both bright and dark scenes.

Its brightness sees the 65S90F managing to reach as high as 1,500 nits on a 10% white HDR test window – a huge increase of almost 50% over the brightness in the same test circumstances achieved by 2024’s 65S90D.

This can be delivered on the 65S90F, too, without causing any of the backlight haloing and clouding problems rival LCD TV technology would typically present when dealing with the sort of contrast the 65S90F loves to show.

Just occasionally, the 65S90F can still sometimes crush the subtle detail out of the picture in some of its presets – but if this becomes problematic to you, then nudging the TV’s Shadow Detail adjustment up to level three or four pretty much fixes the issue without causing any unwanted side effects.

I was also struck by how clean the 65S90F’s dark picture areas and scenes look. There’s really zero sign of the sort of graininess or grey blocking noise that less able OLED screens can show in dark areas, revealing a fantastically granular level of control over the QD-OLED panel even in challenging near-black image areas.

Having so much extra brightness in its arsenal hugely increases the intensity the 65S90F can pump into HDR playback, resulting in HDR images that look more natural and realistic as well as more dynamic.

It feeds also into a significantly richer color performance than the S90D served up, getting much more value out of the QD-OLED pixel design. This is particularly and spectacularly obvious in the hard-to-resist Standard picture preset, but crucially, the more accurate Movie and Filmmaker Mode presets also look richer and warmer than they did on the 65S90D without losing that sense of ‘as the director intended’ authenticity home cinema fans are so often looking for.

On that accuracy point, the 65S90F’s measured color and white balance results with SDR content in Filmmaker Mode average out at marginally above the Delta E average error level of three – anything below this is where the human eye is considered incapable of perceiving a visible difference between what the TV is showing and the established video standards.

But since the results average only misses that Delta E error margin goal of three by a puny 0.48, I’m pretty confident that only the most trained eye will have any chance of spotting anything off-key about the Filmmaker Mode’s glorious efforts.

In fact, thanks to the refinements the 65S90F can apply to its more vibrant colors, the Filmmaker Mode looks as gorgeous in its own calmer, more nuanced way as the much more vibrant Standard mode does, with both presets bringing out the extremes of the QD-OLED panel’s capabilities. Extremes that now include a level of subtlety to go with the potency that just wasn’t there before.

The 65S90F’s extremes of light and color precision also play their part in creating a beautifully crisp and clean picture with both native 4K sources and, thanks to the efforts of Samsung’s latest AI picture engine, upscaled HD images.

The only thing that damages the 65S90F’s sense of clarity and detail is the out-of-the-box motion settings Samsung applies to some of its picture presets, which can cause quite aggressive glitches in the picture during camera pans or around/over fast-moving objects.

Happily, though, it’s possible to tweak these issues away pretty straightforwardly by choosing a Custom setting for the Picture Clarity settings, and then turning off noise reduction and reducing the judder and blur reduction processing components to around level three or four.

Unlike most LCD and even some rival OLED screens, the 65S90F’s pictures don’t lose contrast or suffer from shifting color tones when viewed from even a really wide angle, making it a great option for big families or awkward room layouts.

I could find only two real issues with the 65S90F’s pictures. First, despite being much brighter than its predecessor, its brightness falls a fair way short of the sort of numbers we’re seeing now from the high-end OLEDs out there from the likes of LG, Samsung, and Philips. And second, if the 65S90F is being watched in very high levels of ambient light, its typically stunning black levels can start to look a bit gray.

The brighter OLEDs out there are typically much more expensive than the 65S90F, though, unless you pick up a 2024 model if you can find one. And the circumstances that cause grayness to creep into black areas are rarer and the degree of grayness milder than it was with the 65S90D, so much so that most home setups will seldom notice it.

• Picture quality score: 5/5

Samsung S90F 65-inch review: Sound quality

• 2.1-channel, 40W speaker array
• OTS Lite system accurately positions sound effects
• Dolby Atmos and AI sound modes

The 65S90F’s sound isn’t quite as talented as its pictures, but it still is much better and louder than you might expect from such an ultra-thin TV.

For starters, it gets good traction from its Object Tracking Sound (OTS) system. As its name suggests, this enhancement ensures that soundtrack elements are coming not just from the screen generally, but from the correct part of the screen. The system also manages to stage ambient sounds and music so that they appear, correctly, to be hanging out somewhere beyond the on-screen action.

The 65S90F’s OTS Lite system isn’t quite as uncannily precise with its sound effect positioning as Samsung’s higher-end TVs are – not least because it only carries a 2.1-channel speaker system versus the 4.2.2-channel speaker setups typically provided by those more premium models. But it’s still effective enough to make soundtracks feel detailed, busy and immersive.

The staging includes a good sense of forward impact with hard sounds like gunfire, punches and explosions too, despite the TV lacking any forward-facing speakers, while shrill treble effects avoid sounding distractingly harsh or thin.

The 65S90F isn’t the loudest TV we’ve heard – at least at the sort of volume levels you’ll need to stick to if you don’t want the speakers to start feeling a bit strained. Its speakers have enough headroom, though, to be capable of shifting up at least a few gears as action or horror scenes escalate towards a crescendo – even if they don’t quite have that ‘fifth gear’ required to carry the movie world’s loudest moments all the way home.

The 65S90F even manages to find a bit of bass from somewhere, despite its skinny form. This can succumb to buzzing interference, however, and sound a bit strained with the most extreme bass drops, but such moments don’t crop up all that often.

• Sound quality score: 4/5

Samsung S90F 65-inch review: Design

• ‘LaserSlim’ design at its extremities
• Screw-free stand design
• Ultra-thin bezel

At first glance, the 65S90F looks like one of the most futuristic TVs you’ll see. This is because at its outer edges, the screen is incredibly thin – barely deeper than a couple of credit cards stacked on top of each other. The width of the frame around the screen is also unusually narrow, adding to the feeling that you’re watching pictures being conjured up out of thin air.

The 65S90F is not actually as skinny as it initially appears, though. There’s a much deeper mid-section on its rear hosting the TV’s speakers, connections and electronics. This results in a slightly awkward two-tier appearance if you’re looking at the back of the TV, with the screen seeming like it’s just been stuck onto the chunky section rather than the two areas coming together to forge a truly unified design.

Who in their right mind, though, wants to look at the back of a TV rather than its front? And from the front – and, actually, even from quite wide viewing angles – the 65S90F is a futuristic cutie.

While the 65S90F can be hung on a wall if you wish, most users will probably opt to place it on its included stand. This features a unique design that finds a pair of feet slotting screw-free into the TV’s bodywork, and a metallic plate then slotting onto the feet to create what looks like a centrally mounted pedestal support. The resulting central pedestal enables the TV to sit on pretty much as narrow a piece of furniture as you want.

• Design score: 4.5/5

Samsung S90F 65-inch review: Smart TV and menus

• Tizen 9.0 smart TV system
• Multiple voice control systems
• AI-bolstered content recommendation

The Tizen OS carried by all Samsung TVs is now in its ninth generation, and after a few stumbles along the way, all that experience has paid off handsomely.

For starters, Tizen is now extremely rich with content, including – so far as I can tell – all of the main streaming apps used around the world, as well as many more obscure ones besides.

The only obvious absentee in the UK is the Freeview Play app that brings together all of the streaming services of the UK’s main terrestrial broadcasters. But crucially, each of those catch-up apps is still available on an individual basis.

The Tizen interface can feel a little overwhelming when you’re first presented with it, and it can also run a touch sluggishly for a moment or two after the 65S90F is switched on. Once it’s settled down, though, and you’ve spent just a few moments exploring what it can do, it’s now a friendly and – in the way it learns your viewing habits and recommends content accordingly – highly intelligent TV OS.

Tizen 9.0 has also now resolved most of the navigational quirks that used to affect it when it first switched to a full-screen interface, and it’s customizable enough to easily be adapted to your personal preferences. Also, it can adapt to the personal preferences and viewing habits of different members of your household thanks to its support for multiple user profiles.

Accessing the 65S90F’s setup menus from within the Tizen OS is a bit long-winded, but pressing the settings menu on either of the two remote controls the TV ships with offers a shortcut to all the most-used adjustments.

A notable addition to Samsung’s 2025 menu system is a new AI shortcut option that both makes Samsung’s AI-based picture and sound enhancements easier to access, and makes users more aware that such AI features exist.

Purists likely won’t care for the AI enhancements, of course, and things can get a bit complicated when it turns out that some of the other picture settings you can choose can have an impact on how aspects of the AI enhancements work. But I’d recommend that most people at least experiment with them, even if only with broadcast or sub-4K content too if you prefer how it sharpens things up.

One of the remote controls I just mentioned is a fairly chunky, button-crowded ‘standard’ one, while the other is a much sleeker, less button-heavy smart handset that I suspect will become the one most people use.

• Smart TV & menus score: 4.5/5

Samsung S90F 65-inch review: Gaming

• 4K 144Hz support on all four HDMI ports
• Variable refresh rates support, including FreeSync and G-Sync
• Game hub and Game Bar screens

The 65S90F is an outstanding gaming display. For starters, all of its HDMI ports can take in full bandwidth gaming feeds, meaning you could simultaneously attach four 4K 120Hz-capable consoles and PCs if you wanted to.

All four HDMIs also support variable refresh rates, including in the AMD Freesync Premium Pro format and Nvidia G-Sync (though this is being added via an update), as well as auto low latency mode switching so that the TV automatically switches into its fastest response mode when the TV detects a game is incoming.

When in its Game mode, the 65S90F only takes 9.2ms to render incoming 60Hz feeds – a truly outstanding result for a TV that pretty much halves, too, if the game you’re playing supports 120Hz.

The 65S90F also lets you call up a dedicated Game Bar menu screen rather than the usual TV menus when it knows a game is being played, and from this Game Bar you can both get key information about the incoming gaming feed and access a few gaming aids, including a mini map zoom, the option to raise the brightness of dark picture areas without impacting bright areas, and a crosshair superimposed over the center of the screen.

The Tizen OS homescreen, meanwhile, includes a dedicated Game Hub page, where all of your gaming sources, from connected consoles to game streaming services, are gathered together.

The 65S90F’s gaming performance, finally, is fantastic. Its rich color and contrast are perfectly placed to deliver gaming graphics with exceptional exuberance and dynamism, especially with titles that make particularly aggressive use of high dynamic range. The speedy input lag time ensures that gaming always feels ultra fluid and responsive, too.

The only negative thing to say about the 65S90F’s gaming performance is that unless you’re taking advantage of its HDR Gaming Interest Group (HGiG) support, where the console takes control of the HDR that’s fed out to the TV, the default game settings can cause some distracting brightness fluctuations as you run around any map that has a mix of light and dark areas.

If this is troubling you with whatever game you’re playing, though, you just need to turn off the TV’s dynamic tone mapping setting.

• Gaming score: 5/5

Samsung S90F 65-inch review: Value

• Cheaper QD-OLED option than flagship Samsung S95F
• Enhanced picture quality over S90D predecessor
• Lacks S95F's anti-reflection filter

While the 65S90F is not by any stretch of the imagination cheap, it does sit slightly at the right end of the same price ball park as its key rivals.

Also, more importantly, it’s around £700 / $800 cheaper than its 65-inch S95F sibling, while delivering a more potent sense of QD-OLED technology’s strengths than its S90D predecessor.

The S95F series does look set to deliver a major brightness upgrade over the S90F, to be fair, as well as carrying a really strong anti-reflection filter that the S90F does not have.

But that price difference adds up to a lot of 4K Blu-rays and/or other home theater gear.

• Value score: 4.5/5

Samsung S90F 65-inch review: Also consider...

How I tested the Samsung 65S90F

• Tested over 13 days
• Tested with 4K Blu-rays, multiple streaming platforms and resolutions, Freeview HD broadcasts, and HD Blu-rays
• Reviewed in both dark and light dedicated test room conditions, on its stand in both corner and flat wall positions

The nature of the 65S95F’s QD-OLED technology required me to spend as much time testing it in daylight conditions as I did testing it in darkened rooms, to make sure I wasn’t disturbed by the potential for bright light to impact the screen’s contrast. So it became my full-time living room TV for much of the nearly two weeks I spent with it.

That said, I also tested it under the same specific dark test room conditions TechRadar tests all of our TVs in, with a wide range of disc, game and streaming test content. Disc content included the 4K and HD Blu-rays of It: Chapter One, Blade Runner 2049 and Pan, while for gaming tests, I deployed both a PlayStation 5 and Xbox Series X running such titles as Call Of Duty: Black Ops 6, Forza Horizon 5 and South Of Midnight.

Finally, as ever I put the 65S90F through a barrage of objective tests using Portrait Displays’ Calman Ultimate analysis software, G1 signal generator, and newly released C6 HDR5000 light meter.
