Samsung 77-Inch Class OLED S90F 4K Smart TV (2025 Model) NQ4 AI Gen3 Processor, Upscaling Pro, HDR +, Motion Xcelerator 144Hz, Samsung Vision AI, Alexa Built-in

From the first moment this screen comes alive, it’s immediately clear that Samsung is pushing its OLED territory into entirely new visual territory. The sheer scale of the 77-inch panel is one thing, but paired with the NQ4 AI Gen3 processor, the upgrade feels like a generational leap. There’s almost no content that arrives at your screen where the processor doesn’t seem to work magic—whether it’s a grainy old series, a streaming movie, or high-end gaming footage. Thanks to those 128 neural networks, image detail gets an immediate brush-up, color gets refined, and motion receives an elegant, crisp handling that minimizes any smearing or judder, even in rapid action.

The organic self-emitting pixels of OLED provide contrast levels that feel almost sculptural—deep, ink-like blacks holding their depth even next to the brightest highlights—and Samsung’s HDR+ layer sharpens this further. That combination of pinpoint brightness efficiency and pixel-level dimming creates highlights that pop, but never at the expense of shadow detail. It’s a beautifully balanced performance. The artwork-friendly color accuracy, backed by Pantone validation, seems tailored for artists or designers who aren’t willing to compromise—colors feel precisely rendered, never over-saturated or cartoonish.

Gaming on this panel feels tailor-made for PS5 and PC players, not just in peak resolution but in smoothness. The 4K 120Hz adaptive sync and especially the 144Hz input (when gaming over PC with VRR support) remove the headaches of tearing and stuttering—every frame feels steady, reactive, and immersive. Motion Xcelerator is here too, smoothing action so fluidly in sports that it becomes hard to imagine returning to conventional refresh rates. Whether watching a slow bowler’s delivery or an explosive multiplayer match, this TV transforms motion into an advantage rather than an obstacle.

Samsung’s Vision AI integration is a quiet but crucial evolution—it adjusts not just image detail, but sound, tailoring audio clarity based on the type of content and even the room’s acoustics. While I haven’t seen every feature manifest on this specific model, what surfaced was consistently smart—prioritizing speech clarity in dramas, expanding room-filling ambience during action scenes, and keeping gaming audio tight and directional.

With Alexa built directly into the interface, hands-free adjustments become seamlessly part of daily use—volume, source switches, brief searches, and routine settings all respond without touching the remote. And it’s not just voice control; the on-screen interface feels quick, uncluttered, and deeply integrated with the wider Samsung ecosystem.

One undeniable consideration is the premium price tag—this 77-inch OLED journey isn’t for those on tight budgets. Yet the construction, back-panel cooling design, and rich calibration options all suggest Samsung is aiming this squarely at enthusiasts and professionals alike. Calibration options allow for vet-approved accuracy, and the multiple HDR certifications mean that this isn’t just about marketing —it’s about convenience.
