How to install Samsung S90D QN48S90DAE

Installing the Samsung S90D OLED TV involves a few straightforward steps to ensure optimal performance and safety. Begin by choosing your mounting option: table stand or wall mount. If you’re using a wall mount, select a compatible VESA pattern and mount site that can support the TV’s weight. With the wall mount prepared, place the TV on the stand or mount it securely to the wall, making sure the mounting screws are properly tightened and the TV is level. Position the TV at a comfortable eye level and ensure there is adequate airflow around the unit to prevent overheating.

Next, connect your input devices. Attach your power cable to a surge-protected outlet, and connect HDMI sources such as a 4K Blu-ray player, game console, or streaming device to the HDMI inputs. If you’re gaming, consider using HDMI 2.1 ports to take advantage of 4K at 120Hz and VRR. Connect any soundbar or home theater system via HDMI ARC/eARC or optical output for immersive audio. For smarter features, connect the TV to your home network via Wi‑Fi or Ethernet (if available), and set up Bluetooth peripherals if you’re using wireless headphones or a game controller.

Power on the TV and follow the on-screen setup wizard. Sign in to your Samsung account if you want to sync your preferences across devices, customize your home screen, and enable preferred streaming services. Calibrate the picture for your room using the built-in picture modes—Cinema or Movie mode often provide the most faithful color and tone mapping for OLED content. If you have ambient lighting in your room, you can enable ambient-aware features to balance screen brightness with the surrounding environment. Finally, configure your sound settings and any external speakers, ensuring that input sources and audio outputs are correctly assigned.

For optimal gaming performance, update the TV’s firmware to the latest version, ensure HDMI input is set to the correct mode (enhanced for gaming), and enable gaming features such as game mode and VRR if your console supports them. Regularly check for software updates to gain new features, improved color accuracy, and enhanced compatibility with streaming services and accessories. With careful setup, the S90D delivers immediate, vibrant visuals and a responsive, immersive viewing experience from day one.

Frequently asked questions

What makes the Samsung S90D 48" OLED TV different from standard LED TVs?

The S90D combines OLED’s self-emissive pixels with deep blacks, outstanding contrast, and a wide color gamut that LED TVs struggle to match. Each pixel on OLED emits its own light, enabling true blacks and exceptional clarity in dark scenes. In addition, OLED panels typically offer broader viewing angles and faster pixel response, reducing motion blur for fast-paced content like sports and gaming.

Is this TV suitable for gaming and streaming in 4K?

Yes. The 48" S90D supports 4K UHD resolution at high refresh rates, with HDMI 2.1-enabled inputs for 4K at 120Hz, VRR, and low input lag. This makes it a strong choice for game consoles and PC gaming. It also provides rich streaming capabilities through Tizen OS, giving you access to popular apps and services to enjoy your favorite movies, shows, and games in superb 4K quality.

Does the S90D support HDR formats like HDR10+ and HLG?

Yes. The TV is designed to handle HDR10+ and HLG content, delivering a broader dynamic range to enhance the brightness, color, and contrast of supported movies and broadcasts. This ensures HDR content appears more lifelike and cinematic, with brighter highlights and deeper shadows.

What kind of audio can I expect, and can I connect external speakers?

The S90D provides built-in audio optimized for clear dialogue and immersive effects. For more robust sound, you can connect a soundbar or home theater system via HDMI ARC/eARC or optical output. If you use external components, ensure your audio settings align with your setup to maintain the intended balance between voices and action.

How do I calibrate the picture for the best viewing experience?

Start with the Movie or Cinema picture mode, then adjust brightness, contrast, and gamma to suit your room lighting. For HDR content, use the HDR tone mapping settings to preserve detail in both bright and dark scenes. If you’re watching in a bright room, enable the anti-reflective coating and consider adjusting black levels to prevent crush in dark scenes. Many viewers also favor a warmer color temperature for movie viewing, but feel free to customize based on your preferences.

Can I use this TV with smart home devices and voice assistants?

Yes. The S90D runs on Samsung's Tizen OS and supports integration with popular voice assistants and smart home ecosystems. You can control playback, search for content, adjust volume, and manage connected devices using voice commands or the TV’s on-screen interface, making everyday use more convenient and hands-free.
