Introduction

The Samsung S90D Series represents a high-tier OLED 4K lineup for 2024, positioned just below Samsung’s absolute flagship OLED models. It aims to combine the premium contrast and picture quality of OLED with advanced color processing, gaming features, and smart TV capabilities. Available in multiple screen sizes, the S90D offers an appealing mix of performance, design, and modern features, aimed at cinephiles, gamers, and home entertainment enthusiasts who want top-class visuals without paying the very highest premium.

Available Sizes & Panel Types

The S90D Series comes in a variety of sizes to suit different room scales: 55-inch, 65-inch, 77-inch, 83-inch, etc. Some sizes in certain regions use QD-OLED panels, others use WOLED panels. The difference in panel type affects color performance, brightness, and viewing angle behavior. In general, QD-OLED versions provide enhanced color saturation and better peak brightness.

Display & Picture Quality

OLED and Self-Illuminating Pixels

Because it uses OLED (organic light-emitting diode) technology, each pixel can be lit independently, and turned off for perfect black. This enables a very high contrast ratio. Dark scenes appear deep and rich without the usual glow or backlight bleed seen in LED TVs.

4K Resolution

Every model delivers full Ultra HD resolution (3,840 × 2,160), which ensures sharpness, clarity, and fine detail for movies, games, and streaming content.

Refresh Rate & Motion Handling

The S90D includes a native refresh rate of 100 Hz, with enhanced motion processing that supports motion rates up to 200. Higher refresh modes are especially helpful for gaming or fast action scenes: motion appears smoother, panning is more stable, and the sense of blur is minimized.

Color, HDR, Tone Mapping

• Supports dynamic HDR formats including HDR10+ (with Adaptive / Gaming modes) and HLG.

• Employs perceptual color mapping and “OLED HDR+” processing for brightness boosts in bright scene highlights, as well as preserved detail in shadows.

• “Real Depth Enhancer” (or “Real Depth Enhancer Pro” / similar) is used to increase the perception of depth in scenes, making foreground elements more distinct.

Viewing Angles and Anti-Reflection

• The S90D features “Ultra Viewing Angle” technology. This helps maintain color accuracy and contrast even from more oblique viewing positions, which is especially useful in larger rooms or wide couches.

• It also has an anti-reflection surface to reduce glare from windows or bright lights, improving visibility in brighter ambient conditions.

Processing & Smart Features

NQ4 AI Gen2 Processor

This is the main chip driving picture and smart operations. It performs tasks such as:

• Upscaling lower resolution content (HD, SD) to near-4K quality.

• Managing HDR tone mapping (for HDR10+) and adapting to content and ambient lighting.

• Handling color calibration, contrast enhancement, and motion smoothing where required.

Picture Modes & Calibration

• Filmmaker Mode is included for content creators or users who prefer minimal post-processing so that the content is shown closer to the director’s intent.

• Basic Expert Calibration tools are provided, though perhaps not as extensive as in ultra-premium lines.

• Adaptive modes: brightness or contrast adapt to ambient lighting; gaming modes adapt to reduce lag.

Audio & Sound

Speaker System

The S90D uses a 2.1 channel speaker setup in all sizes, with approximately 40 W (RMS) output. This includes a woofer plus full range speakers, designed to deliver balanced sound with reasonable bass and clarity.

Sound Technologies

• Dolby Atmos is supported, adding immersive vertical height effects when the content source is compatible.

• Object Tracking Sound Lite (or similar) provides a sense of sound movement following objects on screen, enhancing immersion.

• Adaptive Sound Pro / Adaptive Sound adjusts audio presentation depending on the environment and type of content.

• Active Voice Amplifier to make dialogue more audible in noisy environments.

Connectivity & Gaming Capabilities

Ports & Inputs

• Multiple HDMI ports (including HDMI 2.1) allowing for high bandwidth input (needed for high frame rate video, gaming).

• USB ports for external media.

• Wireless: Wi-Fi, Bluetooth; integration with mobile / casting / mirroring functions.

• Built-in voice assistants: support for Bixby; also compatibility with Alexa and Google Assistant in many markets.

Gaming Features

• Very low input lag, especially in Game Mode.

• Support for high refresh rates: up to 144 Hz in many sizes, allowing very smooth motion for gaming.

• Variable refresh rate (VRR) support, which helps avoid tearing and stutter when frame rates vary.

• Auto Low Latency Mode (ALLM), which switches the TV automatically into a mode optimized for gaming when a console or game device is detected.

---

Design & Build

• Slim profile continues the trend in modern TVs, with minimal bezel design so that the display feels immersive.

• Stand design is stable and practical, often allowing space underneath for soundbars.

• Wall mounting supported via standard VESA patterns (varies with size).

• Build materials: premium finishes, attention to cable management, etc.

---

Power & Efficiency

• Power consumption varies by screen size. Larger models draw more watts.

• Standby power is low.

• Features like Eco-Sensor / ambient light adjustment help reduce power usage when full brightness is not required.

---

Strengths

1. Exceptional contrast thanks to OLED’s ability to turn off pixels.

2. Rich, vivid colors especially in QD-OLED versions; strong HDR peak brightness.

3. Excellent gaming credentials: high refresh rate, low lag, VRR and ALLM.

4. Strong viewing angles and anti-reflection performance make it usable in both bright and dark viewing conditions.

5. Immersive sound features like Dolby Atmos and sound tracking, despite the modest built-in speaker wattage.

---

Limitations / Trade-Offs

1. While HDR brightness is strong, in some very bright ambient conditions, the brightness may not compete with the very brightest LED/LCD or Mini-LED models.

2. Built-in audio, though good, cannot replace a serious audio system or high end soundbar for cinematic sound, especially for bass and surround depth.

3. No support for Dolby Vision in many regions; HDR10+ is supported but users who prefer Dolby Vision may see this as a drawback.

4. Cost can be high, particularly for larger sizes.

5. Some motion interpolation / smoothing may introduce artifacts in certain content; very fast motion scenes or panning may show limitations.

---

Use Cases

• Home Theater / Movie Nights: When you can control lighting (dimming lights), the S90D delivers deep blacks, cinematic contrast, and film-style color accuracy.

• Gaming: High frame rate, low lag, VRR make it ideal for gamers using consoles or PCs. Especially good for fast-paced games.

• Mixed Use / Living Room Viewing: Strong performance in bright or partly bright rooms thanks to anti-reflection and good color retention.

• Sports & Live Events: Fast motion clarity, vibrant colors and contrast make sports visually engaging.

• Multi-Viewer Settings: Wide viewing angles mean people sitting off center still have good image quality.

---

Comparison & Market Positioning

• Compared to Samsung’s flagship lines (e.g., if there’s a higher “Pro” or “S95D” line), the S90D may sacrifice slightly in peak brightness or premium extras, but often delivers the bulk of what most users care about.

• Compared to non-OLED LED or QLED TVs, the S90D offers superior contrast, better blacks, and more natural image quality, though often at higher price and with somewhat lower sustained brightness under very bright lighting.

• Against competing OLEDs (other brands), the S90D’s QD-OLED (where applicable) and color processing give it strong advantages in color vibrancy; but brand ecosystem, smart OS, and sound system differences also come into play.

Conclusion

The Samsung S90D Series OLED 4K Smart TV for 2024 is a well-balanced, high-performance television line that delivers much of what many buyers want: premium image quality, excellent gaming support, immersive sound features, and an elegant design. It is particularly strong in dark and mixed lighting environments, where OLED delivers its advantages. For viewers who want vivid visuals, deep blacks, good motion performance, and modern smart features, the S90D is an excellent choice.

While it may not match the sheer brightness extremes of the very top LED or Mini LED models, and the built-in audio isn’t a full theatrical system, its overall package represents great value for those seeking premium quality. For many homes, the S90D will serve as a centerpiece of entertainment for years to come.
