Samsung’s flagship 4K Mini LED TV for 2025, the QN90F, is a masterclass in panel technology. Available in sizes from 43 inches all the way up to a massive 115 inches, it’s a living room showpiece—blindingly bright, elegantly designed, and packed with next-gen gaming features. But while the screen makes you sit up and stare, the “AI” bits mostly make you shrug.
This TV is a stunner. Just don’t expect it to outsmart your phone.
Design: Subtle Flash, Serious Class
The QN90F has near-invisible bezels and an ultra-thin frame, giving it a floating look that’s borderline futuristic. The anti-glare coating is wildly effective—an upgrade borrowed from Samsung’s OLED lineup—and makes this a no-brainer for sunlit spaces.
You’ll also find Samsung’s signature SolarCell remote here, now USB-C rechargeable and as slim and minimal as ever. It feels like the remote Apple would make—if Apple ever made something this nice for TVs.
Picture Quality: As Bright As the Hype
When it comes to brightness, the Samsung QN90F doesn’t play around. With peak HDR brightness soaring above 2,200 nits, it’s easily one of the most luminously intense TVs on the market. Whether you’re watching in a sunlit living room or under harsh overhead lights, the QN90F delivers a consistently vibrant, high-impact image.
But brightness is only half the story. Samsung’s Mini-LED local dimming tech has matured beautifully here. With thousands of dimming zones working overtime, the QN90F serves up black levels that would’ve seemed impossible for an LED panel a few years ago. Blooming—those annoying halos of light around bright objects on dark backgrounds—is so well-controlled it barely registers. You want a scene with a candle in a pitch-black room? Go for it. The flame glows without turning the whole screen into a muddy gray soup.
Shadow detail is preserved with surprising finesse. You won’t lose important details in the darkness, nor will you get blown-out highlights in the bright stuff. Samsung’s tone mapping is surgical here—it stretches dynamic range to its limits without veering into cartoonish contrast or artificial saturation.
Color reproduction is very good, though not quite best-in-class. Panels like Samsung’s own S95D QD-OLED still win the DCI-P3 and BT.2020 color coverage fight by a nose. But the QN90F isn’t exactly hanging back—it delivers punchy, vibrant color that still looks natural. Skin tones are lifelike, skies are rich without being radioactive, and even tricky colors like reds and purples stay in check.
AI Tricks: Flashy but Forgettable
Samsung is leaning heavily into AI this year, positioning the Vision AI suite on the QN90F as a key differentiator—but in practice, its usefulness still feels limited to a handful of niche features.
There’s “Click to Search,” which lets you hit a button during a show and brings up bios of actors or related content. Cool in theory, but about as deep as a movie trivia app. Other features, like wallpaper generation or actor suggestions, are more novelty than necessity. You’ll try it once and then forget it’s there.
Generative wallpaper is another buzzword feature, letting you use prompts to build custom TV backgrounds. It’s fine. But calling it a reason to buy the TV is like buying a PC for the default Windows screensavers.
Samsung’s next-gen AI upscaling is the secret weapon here. It breathes new life into old content—making 1080p and even SD video look shockingly crisp on a massive screen. Old Blu-rays and cable reruns—they all get a visual polish that makes them feel surprisingly modern. It’s seamless, effective, and one of the most genuinely useful features on the QN90F.
Gaming: This Is Where It Gets Fun
The QN90F supports 4K at 165Hz. Yes, really. No one asked for it, but it’s here—and it’s glorious for high-end PC gaming. Console gamers will get buttery 4K/120 with VRR and ALLM support, while PC gamers can stretch out with ultrawide 21:9 or 32:9 formats.
Input lag is microscopic (as low as 2.3ms in Game Mode), and FreeSync Premium Pro keeps the experience smooth. The QN90F is one of the best gaming TVs on the market right now.
Tizen OS: The Smart Platform That Can’t Sit Still
Tizen has improved in recent years, but it still feels like Samsung is trying to reinvent the wheel every year. Menus are deep in places you don’t expect, and the layout changes just enough from year to year to keep users guessing.
That said, it supports every major streaming app, integrates with Alexa and SmartThings, and does the job… eventually. It’s just not as fluid or intuitive as Google TV or webOS.
Pros & Cons
Pros
- Blinding HDR brightness with superb Mini LED contrast
- 165Hz refresh rate with ultra-low input lag
- Nearly bezel-less design with outstanding anti-glare coating
- Excellent upscaling and local dimming
- Great support for next-gen gaming features
Cons
- Vision AI features feel underbaked and gimmicky
- Color gamut still behind top OLED competitors
- Tizen OS not at good as LG’s webOS or Google TV
Final Verdict
The Samsung QN90F is exactly what a flagship 4K TV should be in 2025: razor-sharp, eye-searingly bright, and ready to eat every HDMI signal you throw at it. It’s hardware-forward, design-conscious, and a dream for gamers and cinephiles alike.
But if you’re hoping the “AI” in this Mini LED marvel will change how you watch TV? It won’t. Not yet. Samsung’s Vision AI is more of a feature checklist than a revolution.
Buy this TV for the screen. Buy it for the light-crushing glare resistance. Buy it to dominate Elden Ring in glorious 4K. Just don’t buy it because a remote button promises to tell you who’s starring in La La Land.
