SAMSUNG 77-Inch OLED 4K S90C Series - Vivid HDR and Immersive Sound

Our review of the SAMSUNG 77-Inch OLED 4K S90C finds it best suited for serious home theater fans and gamers who want striking color, deep blacks and built-in spatial audio without adding a soundbar. The biggest reason to buy is the OLED panel combined with Samsung's Neural Quantum Processor and Quantum HDR OLED that together deliver vivid colors, exceptional contrast and reliable 4K upscaling for HD content, so movies, sports and games look noticeably sharper and more lifelike.

Key Features

• SAMSUNG OLED TECHNOLOGY: Self-illuminating pixels produce true deep blacks and broad color range for dramatic cinematic contrast.
• Neural Quantum Processor w/ 4K Upscaling: AI-powered processing refines HD content into sharper 4K-like detail for streaming and broadcast sources.
• Quantum HDR OLED: Scene-by-scene brightness and contrast tuning brings out texture and color accuracy in complex footage.
• Dolby Atmos & Object Tracking Sound Lite: Virtual top speakers and Dolby Atmos create a 3D audio feel that follows on-screen action for more immersion without external speakers.
• Motion Xcelerator Turbo Pro: High refresh rate support up to 120Hz and up to 144Hz for compatible PC content reduces blur and improves fast-motion clarity for gaming.
• LaserSlim Design & SolarCell Remote: A minimalist 4mm depth profile with a solar-charge remote keeps the setup tidy and eco-minded.

Who It's For

The S90C targets viewers who prioritize picture quality and accurate color, including movie lovers, HDR content watchers and competitive gamers who will benefit from high refresh rate support and 4K clarity. It also suits buyers who want strong built-in audio like Dolby Atmos without immediately investing in a soundbar.

Those who need a budget set, an extremely bright LED panel for very bright rooms, or an integrated smart platform different from Samsung's ecosystem may want to compare other models before deciding. Buyers who require the absolute loudest, most bass-forward audio should consider pairing this TV with a dedicated soundbar or subwoofer.

Pros & Cons

Pros

• Outstanding contrast and color accuracy thanks to OLED and Pantone validation, making images look natural and punchy.
• Excellent upscaling and processing via the Neural Quantum Processor for clearer HD to 4K conversion.
• Impressive internal audio with Dolby Atmos and Object Tracking Sound Lite that enhances immersion without external speakers.
• Slim, near bezel-free design that works well on a near flush or modern metal stand and includes a solar-charging remote.

Cons

• Although audio is strong for an internal system, serious home theater fans may still prefer a dedicated soundbar for fuller low-end and higher volume.
• Some users report mixed feelings about functionality and thickness compared with other slim models, so expectations on slimness and features should be checked in person.
