Quick Verdict
We had the Samsung S90F 65" in our Montreal store for three weeks. We threw everything at it: dark-room 4K HDR films, competitive Fortnite at 144 Hz, daytime sports with the blinds open. Here's where it landed.
Overall score: 8.7/10. Stunning picture with infinite contrast and colours that cover nearly the full DCI-P3 spectrum. Gaming performance is exceptional, with input lag measured around 9 ms. The real downsides? No Dolby Vision, and the built-in speakers do the job but won't blow you away. If you're after the best OLED TV 2026 has to offer without emptying your bank account, this Samsung S90F 65 review should settle the question for you.
The S90F 65" sits at the top of our best Samsung TVs 2026 ranking. It earned that spot.
Design & Build Quality
Samsung played it safe with the S90F 65" design, and honestly, that's fine. The panel measures roughly 11.5 mm at its thinnest point, making wall mounting straightforward with the VESA 300x200 bracket. Total depth including the electronics box comes in around 40 mm. That's slim for a 65-inch set.
The Graphite Black front is clean and understated. The Space Titan stand brings a more modern look to the table. Build quality is solid, no creaking or flexing when you handle the panel. At about 16 kg without the stand, two people can manage a wall install without drama.
One gripe: cable management through the stand could be better. With 4 HDMI ports and 3 USB ports to hook up, things get messy fast if you don't plan ahead. Not a dealbreaker, but it's the kind of detail that separates good industrial design from great.
Picture Quality
This is where the Samsung S90F 65 review gets interesting. And where we need to clear something up.
The 65-inch doesn't have the same panel as the 55-inch. The 65" runs a true QD-OLED, five layers, with blue sub-pixels and quantum dot colour filters to produce reds and greens. The 55"? That's a WOLED panel. Different technology, lower brightness, smaller colour volume. If you're shopping for the S90F specifically because of the QD-OLED, you need the 65". This is the QD-OLED vs WOLED difference that most reviewers gloss over, and it matters.
Now, the Samsung S90F picture quality itself.
Blacks are perfect. Not "really good," not "deep." Perfect. Every pixel turns off independently, giving you infinite contrast. In a dimly lit hallway scene from a thriller, the gap between this and a standard LED is impossible to miss. Zero haloing around bright objects, zero milky grey in the shadows.
The NQ4 AI Gen3 processor handles 1080p upscaling well. We tested with streaming content and the result was sharp, no visible artifacts. Samsung's AI analyzes each scene and adjusts processing frame by frame. In practice, that means less video noise and more detailed textures, especially in wide shots.
For brightness, the S90F 65" QD-OLED hits roughly 1,300 to 1,500 nits peak HDR on a 10% window, depending on measurement conditions. That's more than enough for convincing specular highlights in an HDR film. Full-screen white HDR drops to around 250 nits. That's an OLED limitation across the board, not specific to the S90F. In a living room flooded with afternoon sunlight, you'll notice. In the evening or a controlled room, it's a non-issue.
The anti-reflective coating helps too. We tested the S90F facing a window in the store and reflections were toned down, not eliminated. The S95F with its Glare Free 2.0 does better here, but the S90F holds its own for an OLED without the premium filter.
Colours & HDR Performance
DCI-P3 coverage on the S90F 65" brushes up against 99%. That's the kind of number that makes colourists smile, and in the real world, it translates to deep reds, saturated greens, and blues that stay blue instead of drifting purple. QD-OLED pulls this off because the quantum dots produce pure colours without the white sub-pixel dilution you get with WOLED.
On the HDR front, Samsung goes with HDR10+ (including Adaptive and Gaming modes) and HLG. No Dolby Vision. Let's be straight about this: it's a miss. Dolby Vision is the most widely supported dynamic HDR format on streaming platforms like Netflix and Disney+. Samsung doesn't include Dolby Vision in any of its TVs, period. If that's a hard requirement for you, you'll need to look elsewhere. But in practice, HDR10+ does solid work, and the Samsung S90F HDR brightness of roughly 1,400 nits peak makes HDR content look the way it should.
What does that look like on screen? On Dune: Part Two in 4K HDR, desert scenes had warmth and depth that pulled you in. Shadow detail stayed visible without crushing the highlights. During an NHL game in HDR, the ice was white without being blinding and the red jerseys kept their punch. That's what you expect from a QD-OLED at this level.
BT.2020 coverage lands somewhere between 75% and 86% depending on the measurement method. That's respectable for the current standard, and frankly, native BT.2020 content is still rare.
Gaming Performance
The S90F 65" is a monster for gaming. No other way to put it.
The Samsung S90F input lag gaming numbers tell the story: around 9 ms in Game Mode at 4K/60 Hz puts it among the fastest TVs you can buy. Push it to 120 Hz and it drops below 5 ms. Pixel response time, roughly 1 to 3 ms, virtually eliminates motion blur. On an OLED, each pixel changes state almost instantly, delivering motion clarity that even the best LEDs can't touch.
Refresh rate tops out at 144 Hz, beating the 120 Hz standard on current consoles. For PC gamers with a GPU capable of pushing 4K past 120 fps, that's a tangible advantage. VRR is handled through AMD FreeSync Premium Pro and NVIDIA G-Sync compatibility, covering pretty much everyone. ALLM (Auto Low Latency Mode) flips into Game Mode automatically when you fire up a console. Small thing, but it saves you from digging through menus every time.
All 4 Samsung S90F HDMI 2.1 ports support 4K at 144 Hz with 48 Gbps bandwidth. No "primary" port and three second-tier ones like some models pull. Plug in your PS5, Xbox, PC, and a Blu-ray player, and every source gets the TV's full capabilities. That makes it a serious contender for the best 4K 120Hz gaming TV this year.
In practice, we played Fortnite at 120 Hz on PS5 in the store. The fluidity was immediate, camera rotations were smooth, and Game Mode didn't wash out the colours. On an RPG like Final Fantasy VII Rebirth, the QD-OLED's cinematic rendering gave cutscenes another dimension entirely. And on a racing game, Motion Xcelerator 144 Hz kept track textures sharp even through fast corners.
How does the S90F stack up against the QN90F Neo QLED? The Neo QLED is brighter for HDR gaming (more nits full-screen), but it can't compete with the infinite contrast and response time of OLED. If you game in the evening in a dimmed room, the S90F wins. If you game during the day with the blinds up, the QN90F deserves a look.
Audio
The S90F's audio system delivers 40 watts in a 2.1-channel configuration with Dolby Atmos support. The Samsung S90F Dolby Atmos sound works through OTS Lite (Object Tracking Sound), which tries to follow the on-screen action by virtually shifting the audio. For evening news or a talk show, it's perfectly fine. Dialogue is clear, centred, and doesn't sound tinny.
For an action movie or an immersive gaming session? Different story. Bass lacks depth and the OTS Lite spatial effect stays subtle compared to a real surround setup. Samsung knows this and offers Q-Symphony Pro, which syncs the TV's speakers with a compatible Samsung soundbar. The TV and soundbar work together instead of one replacing the other.
Our take: the S90F deserves a soundbar. Not because its audio is bad, but because a screen this good visually deserves audio that keeps up. We've got a soundbar buying guide that can help you pick the right match.
Connectivity & Smart TV
Four HDMI 2.1 ports, all capable of 4K at 144 Hz, with eARC on one of them. Three USB-A ports for an external drive or a dongle. One Ethernet port for anyone who prefers a wired connection over Wi-Fi.
Speaking of Wi-Fi: it's Wi-Fi 5. Not Wi-Fi 6, not Wi-Fi 6E. In 2026, that's a bit disappointing for a TV at this level. In practice, Wi-Fi 5 handles 4K streaming without issues, but if your router is on a different floor, you might notice the difference. Bluetooth 5.3 is current and handles headphone or keyboard pairing without fuss.
On the software side, Tizen gets the job done. The interface is snappy, streaming apps launch quickly, and the SmartThings hub lets you control your Matter-compatible smart home devices from the remote. Bixby and Alexa are built in for voice control. The SolarCell remote charges from ambient light, which is a nice eco-friendly touch.
Nothing groundbreaking here, but everything works as expected. That's all you really want from a smart TV: stay out of the way.
How It Stacks Up Against the Competition
The S90F 65" holds a strategic spot in the Samsung lineup. Here's how it compares to the other models we carry in store.
The S95F is the big sibling. QD-OLED across all sizes (not just the 65"), peak brightness around 2,300 nits, 60W audio in a 4.2.2-channel setup, and the Glare Free 2.0 anti-reflective coating. It's the best Samsung TV, full stop. But it costs roughly 30% more than the S90F 65". The Samsung S90F vs S95F question comes down to whether the extra brightness and better speakers justify that premium for your setup.
The QN90F Neo QLED plays in a different technology league. No OLED here, but a Mini LED backlight that pushes brightness higher (estimated 1,500 to 1,800 nits) with a native contrast ratio around 8,000:1. For a very bright living room, the QN90F has the edge. But the S90F's infinite contrast and perfect blacks are in another category entirely.
The QN80F is the entry point of the family. Standard LED, 120 Hz, 20W audio, and DCI-P3 coverage around 87%. It's a good TV for the money, but the comparison stops there. The picture quality gap between it and the S90F is visible to the naked eye.
| Spec | S90F 65" | S95F 55" | QN90F 55" | QN80F 55" |
|---|---|---|---|---|
| Panel | QD-OLED | QD-OLED | Mini LED VA | LED VA |
| Refresh rate | 144 Hz | 144 Hz | 144 Hz | 120 Hz |
| Contrast | Infinite | Infinite | ~8000:1 | ~5000:1 |
| HDR pic (nits) | ~1 400 | ~2 300 | ~1 650 | ~700 |
| Input lag | ~9 ms | ~9 ms | ~10 ms | ~12 ms |
| DCI-P3 | ~99% | ~99% | ~93% | ~87% |
| Audio | 40W 2.1ch | 60W 4.2.2ch | 60W 4.2.2ch | 20W 2.0ch |
| HDMI 2.1 | 4 ports | 4 ports | 4 ports | 4 ports |
| VRR | FreeSync Premium Pro | FreeSync Premium Pro | FreeSync Premium Pro | FreeSync |
| Dolby Atmos | Yes | Yes | Yes | Yes |
| Design (thickness) | 39.9 mm | 11.5 mm | 25.4 mm | 24.9 mm |
The S90F 65" hits the sweet spot: flagship QD-OLED technology without the flagship price. It's the OLED for people who want the best panel they can get on a reasonable budget. The Samsung S90F 65 price in Canada makes it the most accessible QD-OLED in the 2026 Samsung range.
Who Should Buy the S90F 65"?
The movie buff with a dark room. Infinite contrast, perfect blacks, near-100% DCI-P3 coverage. If your living room has blackout curtains and you watch films in the evening, the S90F 65" will give you chills. This is its natural habitat.
The serious gamer. Sub-10 ms input lag, 144 Hz, four full HDMI 2.1 ports, VRR with FreeSync Premium Pro and G-Sync Compatible. Hook up everything you own, it'll keep up. Very few TVs offer this combination at this price point.
The OLED shopper on a budget. The S90F 65" delivers roughly 80% of the S95F's performance for significantly less money. If you don't need the extra brightness or the flagship's premium speakers, this is the smart buy.
Not ideal for: if one thing stood out in this Samsung S90F 65 review, it's that bright living rooms drenched in natural light without curtains aren't its strength. The roughly 250 nits full-screen brightness and lack of Glare Free 2.0 can be a problem in broad daylight. In that case, the QN90F Neo QLED will be more comfortable.
