Samsung S90F OLED TV Review: Features, Gaming, and Buying Advice

The Samsung S90F is a 2025 4K OLED TV positioned between the entry-level S85F and flagship S95F. Its main strengths are deep OLED blacks, strong gaming support, the NQ4 AI Gen3 processor, and Samsung’s Tizen smart platform. It is a good fit for movies and gaming, but it does not support Dolby Vision, and some specifications differ by screen size and region.

Samsung S90F key specifications

Always check the full model code on the retailer listing. Samsung sells regional variants, and the smaller 42- and 48-inch versions use OLED HDR rather than the OLED HDR+ designation advertised for larger S90F sizes.

Picture quality

Because each OLED pixel produces its own light and can switch off independently, the S90F delivers true black areas without the blooming seen around bright objects on many LCD TVs. That makes it particularly effective for films, games, and dark-room viewing. Wide viewing angles also help when people sit away from the center.

Samsung’s OLED HDR+ processing adjusts brightness and contrast, while 4K AI Upscaling Pro improves lower-resolution sources. Upscaling can make compressed video look cleaner, but it cannot restore detail that is absent from the source. For an accurate image, start with Movie or Filmmaker Mode and disable excessive sharpening or motion smoothing.

Gaming performance

The S90F’s fast pixel response and variable refresh-rate support make it well suited to console and PC gaming. Current consoles generally target up to 4K at 120Hz. The advertised 4K 144Hz mode requires a compatible PC graphics card, game, HDMI connection, and settings; it does not make ordinary television or 60fps games run at 144fps.

Auto Low Latency Mode can switch the TV into its low-lag gaming configuration, while Samsung’s Game Bar exposes refresh-rate, aspect-ratio, and VRR controls. Verify the number and bandwidth of HDMI ports on the exact regional model if you plan to connect several current-generation consoles, a gaming PC, and an eARC sound system.

HDR formats and streaming

The S90F supports HDR10+ but not Dolby Vision. Services and discs that offer Dolby Vision normally fall back to HDR10 when connected to the TV, so content still plays in HDR but without Dolby Vision’s dynamic metadata. Buyers with a large Dolby Vision library may prefer an OLED from a brand that supports that format.

Tizen provides major streaming services, Samsung TV Plus, voice features, and smart-home controls, though app availability depends on the country. The interface includes recommendations and promotional areas, so buyers who prefer a simpler home screen may still use an external streaming device.

Sound quality

Dolby Atmos and Object Tracking Sound Lite can create a wider sound field than basic television speakers, and Q-Symphony can coordinate compatible Samsung soundbars with the TV. The built-in system is adequate for everyday viewing, but a soundbar with a subwoofer will provide clearer dialogue and substantially stronger bass in a large room.

Design and placement

The slim panel and narrow bezel look clean on a stand or wall. Check the stand width, VESA pattern, cable clearance, and total weight for the chosen size before buying furniture or a mount. OLED screens can reflect windows and lamps, so avoid placing the S90F directly opposite a strong light source. The S95F is the Samsung model aimed more directly at viewers who need the company’s Glare Free screen treatment.

What to consider before buying

• No Dolby Vision: important for viewers who specifically want that HDR format.
• Size-specific differences: HDR branding, chassis details, and panel characteristics can vary.
• OLED image retention: vary content and use the built-in panel-care features if displaying static logos or desktop elements for long periods.
• Room brightness: OLED excels in controlled lighting, while a high-brightness mini-LED TV may suit a sunlit room better.
• Model age and price: the S90F is a 2025 model. Compare its discounted price with current Samsung OLEDs rather than paying its original launch price in 2026.

Should you buy the Samsung S90F?

Buy the S90F if you want excellent black levels, wide viewing angles, responsive gaming, 4K 144Hz PC support, and Samsung’s smart-TV ecosystem at a meaningful discount. It is strongest in a mixed movie-and-gaming setup where Dolby Vision is not a requirement.

Choose another model if your room is extremely bright, you require Dolby Vision, or a current model costs only slightly more. Before ordering, compare the exact size and model code on Samsung’s OLED TV pages, then review independent measurements for that same variant.
