Samsung QN55S90DAFXZA 55 in 4K OLED Smart TV - Vivid Contrast

In this review of the Samsung QN55S90DAFXZA 55 in 4K OLED Smart TV with Dolby Atmos and included Austere HDMI cable, the bottom line is simple: this set is for viewers who want OLED contrast and smart features plus a single cable that supports high-fidelity audio. The OLED panel delivers deep blacks and Pantone-validated color while the bundled Austere 4K HDMI cable simplifies hookup and supports HDMI ARC for better audio passthrough. For gamers with a compatible 4K PC, the Motion Xcelerator Turbo 144Hz option promises very smooth motion when the source supports it.

Key Features

• OLED Technology: Deep blacks and bright highlights produce a more cinematic image with high perceived contrast across dark and light scenes.
• OLED HDR+: Scene-by-scene brightness boosting improves highlight detail and makes HDR content appear punchier and more lifelike.
• Motion Xcelerator Turbo 144Hz: When paired with a compatible gaming PC supporting 4K, fast-paced games and action scenes render with reduced blur and smoother motion.
• Real Depth Enhancer: Foreground contrast is adjusted to add perceived depth so subjects separate from backgrounds more naturally.
• Dolby Atmos and HDMI ARC: Built-in Dolby Atmos support and the Austere cable with ARC help deliver higher-fidelity streaming audio to connected sound systems.
• Austere 3S-4KHD2 2.5m HDMI: The included HDMI cable is designed for 4K performance and a clean single-cable connection for video and high-quality audio.

Who It's For

The QN55S90DA is aimed at home theater enthusiasts who prioritize picture quality and contrast from an OLED panel and who want an out-of-the-box cable solution that supports ARC and high-quality audio. It also suits discerning streamers who want Dolby Atmos support and viewers who watch a lot of HDR content and cinematic material.

Shoppers who need an extremely bright LED panel for very bright rooms or those who require a TV with non-OLED-specific longevity considerations should compare alternative LED or mini-LED models. Gamers without a compatible 4K PC for 144Hz will still get smooth motion, but will not get the full benefit of Motion Xcelerator Turbo 144Hz.

Pros & Cons

Pros

• Excellent contrast and accurate color from the OLED panel for cinematic picture quality.
• OLED HDR+ increases perceived brightness and detail in HDR content.
• Included Austere HDMI cable with ARC simplifies setup and supports higher-fidelity audio connections.
• Motion Xcelerator Turbo 144Hz provides a clear advantage when paired with a compatible 4K gaming PC.

Cons

• Top-tier benefit of 144Hz requires a compatible 4K PC source, so many users may not access that feature.
• OLED panels can be more sensitive to room lighting compared with very bright LCD alternatives in brightly lit rooms.

Our Verdict
