For years, investing in an OLED television felt like an exercise in compromise. While self-lit pixels deliver unmatched black levels and infinite contrast, older OLEDs frequently struggled to combat ambient daylight reflections in bright living rooms. Meanwhile, avid console and PC gamers often had to juggle sluggish picture processors, aggressive auto-dimming during dark scenes, and limited HDMI 2.1 bandwidth.

The Samsung 65-Inch Class S90F OLED 4K Smart TV (2025 Model), detailed across Samsung’s official OLED lineup, tackles these exact issues. Powered by Samsung’s upgraded NQ4 AI Gen3 processor with 128 neural networks, a native 144Hz refresh rate, and enhanced OLED HDR+ brightness, it positions itself as the premier sweet spot in the premium 65-inch category. Below is an honest, hands-on review evaluating its panel performance, motion processing, gaming chops, and day-to-day usability.

Quick Verdict

The Samsung S90F (2025) is one of the most well-rounded high-end televisions currently available. By pairing the natural contrast strengths of OLED with significant full-screen brightness gains and the heavy computational muscle of the NQ4 AI Gen3 chip, it excels across movies, fast-paced sports, and competitive gaming. While Samsung continues to eschew Dolby Vision licensing, the S90F’s sheer color volume, class-leading anti-reflective screen coating, and four 144Hz HDMI 2.1 ports make it a benchmark performer.

Pros:

True inky blacks with zero blooming: Self-emitting OLED pixels ensure pristine dark-room movie contrast without light haloing around subtitles.
Class-leading peak brightness for OLED: OLED HDR+ delivers punchy specular highlights and noticeable screen luminance improvements over earlier generation panels.
Top-tier NQ4 AI Gen3 processing: 128 neural networks noticeably reduce banding and compression noise on low-bitrate cable, streaming, and sports broadcasts.
Uncompromising 144Hz gaming suite: All four HDMI ports support full-bandwidth HDMI 2.1 with VRR, FreeSync Premium Pro, and sub-10ms input lag.
Refined One UI Tizen interface: Smooth, responsive navigation with unified smart home controls and generous free ad-supported streaming via Samsung TV Plus.

Cons:

No Dolby Vision support: Relies exclusively on HDR10 and HDR10+, meaning you miss dynamic metadata formatting on select Dolby Vision streaming titles.
Built-in audio lacks sub-bass weight: Despite Dolby Atmos processing, the ultra-slim chassis limits internal speaker resonance; a dedicated soundbar is practically mandatory for cinema sound.
Premium price tier: While cheaper than Samsung’s flagship S95F with its matte screen, it remains a significant financial investment.

In-Depth Review: Hands-On Experience

1. Design and Aesthetic (LaserSlim Profile)

The aesthetic presentation of the S90F is striking. Its “LaserSlim” architecture means the upper section of the panel is barely thicker than a smartphone, expanding only slightly toward the lower center to house the power supply, motherboard, and speaker drivers.

The bezels are virtually bezel-less, framed by a subtle gunmetal-brushed aluminum border that disappears in dim lighting. The included central pedestal stand provides solid stability with a relatively small desktop footprint, allowing the TV to sit easily on medium-sized media consoles without requiring wide furniture. Cable routing channels along the rear of the stand keep power and HDMI lines neatly concealed.

2. Picture Quality, Contrast, and Color Accuracy

Where the S90F immediately differentiates itself from standard LED and entry-level QLED models is its pixel-level light control:

Infinite Contrast: Because each of the 8.3 million pixels turns completely off when displaying black, starfields in sci-fi films and dark alleyways in neo-noir thrillers display true black rather than dark charcoal. Subtitles generate zero light bleed into adjacent letterbox bars.
OLED HDR+ Brightness: Historically, standard OLEDs looked dim in sunlit rooms. The 2025 S90F pushes higher sustained brightness, ensuring midday viewing in living rooms with sheer curtains is comfortable and vibrant.
Color Reproduction: Pantone-validated color rendering produces deeply saturated reds, emerald greens, and true-to-life skin tones. Colors retain full saturation even at high brightness levels, dodging the washed-out white tint that can affect some competing panels.
Wide Viewing Angles: Contrast, brightness, and color saturation remain rock-solid even when sitting at steep 45-degree off-axis angles, making it an exceptional display for wide sectional seating arrangements.

3. NQ4 AI Gen3 Processor: Upscaling and Motion Handling

The heart of the 2025 S90F is the NQ4 AI Gen3 processor, upgraded to leverage 128 distinct neural networks:

4K AI Upscaling Pro: Standard definition feeds, compressed 720p cable sports, and legacy YouTube videos are cleaned up with remarkable fidelity. Edge contours are sharpened and digital compression artifacts are smoothed out without introducing artificial “waxy” facial textures.
AI Motion Enhancer Pro: Watching high-speed hockey, tennis, or soccer reveals one of the most tangible improvements: the processor actively tracks fast-moving balls and reduces judder and trailing artifacts without triggering the unnatural “soap opera effect.”
Auto HDR Remastering: Standard dynamic range (SDR) content receives intelligent scene-by-scene luminance expansion, giving catalog SDR movies brighter highlights and punchier visual dynamics.

4. Gaming Performance: 144Hz and Variable Refresh Rate

If you connect modern gaming hardware, the S90F functions like an oversized high-performance esports monitor:

Four Full-Spec HDMI 2.1 Ports: Unlike competitors that offer only two high-bandwidth ports (one of which is often eaten by the eARC soundbar connection), all four ports on the S90F support 4K@120Hz for PS5/Xbox Series X, and up to 4K@144Hz for high-end gaming PCs.
Ultra-Low Input Lag: Game Mode clocks in at an imperceptible ~5ms at 144Hz and under 10ms at 60Hz.
Samsung Gaming Hub & Game Bar: The pop-up Game Bar provides real-time readouts of current FPS, HDR status, and VRR sync. Cloud gamers can launch Xbox Game Pass and GeForce NOW directly from the TV dashboard with zero console hardware.

5. Audio Quality and Dolby Atmos

The integrated 40W 2.1-channel sound system delivers clear dialogue separation and handles casual daytime TV viewing with ease. With Object Tracking Sound Lite (OTS Lite) and built-in Dolby Atmos decoding, directional audio cues subtly track movement across the screen.

However, physics cannot be cheated: the razor-thin chassis has no physical room for a resonant subwoofer chamber. Low frequencies drop off steeply below 75Hz, leaving cinematic explosions and deep musical basslines feeling anemic. To get audio that matches this display’s breathtaking picture, pairing it with a high-end soundbar or AVR surround setup using Samsung Q-Symphony is strongly advised.

Who Should Buy the Samsung 65-Inch S90F?

Ideal For:

Cinephiles and Movie Enthusiasts: Viewers who prioritize true reference-grade black levels, zero light blooming, and cinematic color accuracy in dark-to-moderately-lit rooms.
Hardcore Console and PC Gamers: Anyone running a PS5, Xbox Series X, or high-end PC gaming rig who demands 4K@144Hz, FreeSync Premium Pro, and four uncompromised HDMI 2.1 ports.
Live Sports Fans: Viewers who watch fast-moving games and require class-leading motion interpolation without blur or ghosting.
Spacious Living Rooms with Wide Seating: Families and entertaining spaces where viewers sit across wide angles and need uniform picture quality from any seat.

Not Recommended For:

Direct-Sunlight Solariums: While bright for an OLED, direct afternoon sunlight hitting the glass can cause purple-tinted reflections; ultra-bright Mini-LEDs (like Samsung’s QN90 series) fare better under punishing direct sun.
Dolby Vision Purists: Enthusiasts with extensive collections of Dolby Vision UHD 4K Blu-rays or those unwilling to rely on standard HDR10/HDR10+ formatting.
Tight Budgets: Buyers looking for basic 65-inch screen real estate for casual news watching will find far better monetary value in entry-level QLEDs like the Samsung Q7F.

Frequently Asked Questions (FAQ)

1. Does the Samsung S90F support 4K at 144Hz on all HDMI ports?

Yes. All four HDMI ports on the S90F are full-bandwidth HDMI 2.1 connections capable of up to 4K resolution at 144Hz with Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM). This allows you to connect multiple modern consoles, a gaming PC, and a soundbar via eARC without sacrificing high-frame-rate performance.

2. What are the chances of OLED burn-in on the S90F?

The S90F incorporates comprehensive hardware- and software-level burn-in mitigation, including real-time pixel shifting, logo brightness detection, and automated background panel refresh cycles that run when the screen is powered down. Under standard mixed home usage (movies, streaming, rotating games, TV shows), the risk of permanent image retention is exceptionally low.

3. How does the S90F handle streaming content without Dolby Vision?

When streaming content formatted in Dolby Vision on Netflix, Apple TV+, or Disney+, the TV automatically maps the visual feed to standard HDR10 or HDR10+. Combined with Samsung’s NQ4 AI Gen3 dynamic tone-mapping algorithms, you still receive vibrant colors, deep blacks, and balanced highlights.

4. What is the main difference between the S90F and the higher-tier S95F?

The step-up S95F typically includes an upgraded specialized matte anti-reflective coating (Glare-Free technology), an external One Connect Box for clutter-free cable management, and a slight bump in peak full-screen HDR brightness. For most consumers, the S90F provides approximately 90–95% of the S95F’s visual performance at a considerably lower price point.

5. Can I use the S90F as a PC monitor?

Yes, and it performs exceptionally well in this role. With native 144Hz support, AMD FreeSync Premium Pro compatibility, instant per-pixel response times, and customizable aspect ratios (such as 21:9 or 32:9 Ultrawide Game View via the Game Bar), it functions as one of the best large-format gaming displays on the market.
