Shopping for a new TV is part science, part emotion, and part “how many HDMI ports does it have so I can keep all my toys plugged in?” If you’re looking at our Samsung 65-Inch Class OLED S90F 4K Smart TV review, you already know Samsung put a lot of tech into this one.

Below, we break down what matters to you: picture, performance, gaming chops, smart features, setup, and whether this is worth your money compared with the competition.

Quick verdict: the S90F delivers excellent OLED contrast and vibrant colors with low input lag and strong gaming features. It’s a great pick if you want OLED pop with Samsung’s processing and smart platform, but it’s not the absolute brightest OLED, and some picky viewers may want to tweak picture settings.

Samsung 65-Inch Class OLED S90F 4K Smart TV Review: The specs you actually care about

Display tech: OLED (4K).
Resolution/refresh: 4K, 120 Hz native; Motion Xcelerator 144Hz and VRR up to 144Hz for gaming.
HDR support: HDR10+ (no Dolby Vision).
OS / smart platform: Samsung Tizen (Netflix, Prime Video, YouTube preinstalled).
Audio: built-in speakers rated around 40W and Dolby Atmos support.
Inputs: 4 HDMI ports, 2 USB, Ethernet, Bluetooth, Wi-Fi.
Dimensions/weight: 56.9″ W × 35.3″ H × 10.4″ D (with stand), 49.6 lb. VESA 300 × 200 mm.

Picture quality: OLED blacks, lively color

You get the usual OLED strengths: inky blacks and excellent contrast that make movies and dark scenes sing. Samsung’s S90F pairs that panel with its NQ4 AI processor and 4K AI Upscaling Pro, which helps lower-resolution content look cleaner on a big 65-inch screen. If you watch a lot of streaming shows or Blu-ray, you’ll notice deep shadow detail and punchy colors right away.

A couple of caveats: compared with Samsung’s more premium S95F/S95 models, the S90F can be slightly less bright in some HDR content, and some presets show a touch of black crush or aggressive motion processing out of the box. That’s fixable; you’ll need to tweak picture mode and shadow detail, but it’s worth noting if you want perfect out-of-the-box settings. Reviewers recommend allowing some setup time to achieve the best image.

HDR, brightness, and real-world viewing

HDR10+ support means dynamic metadata for compatible content, and Samsung’s processing does a solid job with tone mapping. Still, if you spend lots of time in bright rooms and want the brightest highlights possible, some competing OLEDs (and certain mini-LED LCDs) will hit higher spec numbers for HDR peak brightness. For most living-room setups, the S90F looks brilliant; for sun-drenched rooms, compare it against the brightest OLED options first.

Gaming: Fast, responsive, and future-proof

If you’re a gamer, the S90F is a real contender. Native 120Hz with Motion Xcelerator up to 144Hz, AMD FreeSync / VRR support, and low input lag make it well-suited for PS5, Xbox Series X/S, and PC gaming. Many reviewers praise its Game Mode performance. It’s responsive and keeps motion smooth during fast action. If you want a TV that plays nicely with high-frame-rate PC gaming or next-gen console features, the S90F should be on your shortlist.

Smart features and usability

Samsung runs Tizen here, and it’s smooth, fast, and stocked with the major streaming apps (Netflix, Prime Video, YouTube). Samsung Vision AI and voice assistants are on board, and the remote is the familiar Samsung SolarCell style on many 2025 models. If your ecosystem already uses Samsung gear, the smart TV features integrate neatly.

Sound: Decent, but consider a soundbar

Built-in audio hits around 40 watts and supports Dolby Atmos processing, so you’ll get respectable sound for shows and casual movie nights. That said, like most flat TVs, the S90F can’t replace a dedicated sound system if you want immersive home-theater audio. If dialogue clarity or booming action scenes matter, plan a budget for a soundbar or AVR down the line.

Connectivity, ports, and setup

Four HDMI ports are standard and helpful if you run multiple consoles, a streamer, and a PC. Two USB ports, Ethernet, and Wi-Fi cover the rest of the basics. It’s VESA-mount friendly at 300 × 200 mm, and the weight (~49.6 lb) means wall mounting is doable, but you’ll want two people and a solid bracket.

Pros and cons

Pros

Gorgeous OLED black levels and contrast.
Strong gaming features (120Hz, 144Hz Motion Xcelerator, VRR).
Samsung’s Tizen smart platform and good upscaling.

Cons

Not the absolute brightest OLED on the market, competitors sometimes edge it in HDR peak brightness.
Default picture presets may need tweaking to avoid black crush or heavy motion processing.
Built-in speakers are fine, but not a replacement for a soundbar.

How the S90F compares

Compared with Samsung’s higher-end S95F, the S90F is usually a bit cheaper but slightly behind in peak HDR brightness and a few premium tweaks. Against LG’s C-series (e.g., C4/C5), Samsung brings brighter panels in some modes and Samsung’s processing advantages, while LG often offers Dolby Vision and slightly different tone mapping; your preference for color science matters here. Reviewers recommend the S90F as an excellent value in Samsung’s 2025 lineup.

Skip or compare if:

You want the brightest possible HDR highlights without having to tweak picture settings.

Final tips before checkout

Calibrate or pick the right picture mode. Out-of-the-box presets aren’t perfect. Take 15–30 minutes to pick Movie/Cinema mode and adjust shadow/detail settings.
Plan audio upgrades. Add a soundbar for a fuller movie experience and clearer dialogue.
Check prices across retailers. Samsung’s models, such as S90D vs S90F, often receive quick discounts during sale events; be sure to hunt around.
