HDR OLED+ combines the self-illuminating pixels of OLED technology with Quantum Dot. This delivers perfect blacks, exceptional brightness, and a wider, more accurate range of colors, enhancing your viewing experience with incredible depth and detail, especially in HDR content.
The Neural Quantum Processor 4K uses advanced artificial intelligence to analyze and upscale all content, regardless of its original resolution, to near-4K quality. It also intelligently optimizes brightness, contrast, motion, and even sound, ensuring the best possible visual and audio output.
Absolutely. The Samsung S90F is highly optimized for gaming, offering a refresh rate of up to 144Hz, ultra-low input lag, Auto Low Latency Mode (ALLM), and full HDMI 2.1 support. These features ensure smooth, responsive, and immersive gameplay.
The TV runs on Samsung's Tizen OS, providing access to the Smart Hub. This centralizes streaming apps, games, and live TV. It also includes SmartThings integration for controlling compatible smart home devices and supports various voice assistants for convenient control.
For the 77-inch model, the product dimensions with the stand are approximately 1058.6 mm (Height) x 1718.5 mm (Width) x 359 mm (Depth). These measurements are useful for planning your TV placement.
Object Tracking Sound Lite is a feature that delivers immersive, directional audio. It uses the TV's speakers to create sound that appears to follow the motion of objects on the screen, enhancing the realism of your viewing experience.
To care for your OLED screen, gently wipe it with a soft, dry microfiber cloth. For smudges, slightly dampen the cloth with distilled water; never spray liquid directly onto the screen. It's also recommended to avoid displaying static images or logos for very long periods at high brightness to prevent image retention.
Check if the power cord is securely plugged into both the TV and a working wall outlet. Ensure the remote control batteries are not depleted. Try plugging another device into the same outlet to confirm power availability.
Verify the input source is transmitting high-quality content (e.g., 4K HDR). Go to Picture Settings in the TV menu and try different Picture Modes (e.g., Standard, Movie, Dynamic) or adjust individual settings like brightness, contrast, and color. Ensure 'Game Mode' is activated when gaming for optimal performance.
Check the TV's volume level and ensure it's not muted. Verify the audio output setting in the TV's Sound menu (e.g., TV Speaker, Optical, HDMI eARC). If using external speakers, ensure they are properly connected and powered on.
Check your internet connection (Wi-Fi or Ethernet) to ensure it's stable and strong. Try restarting the TV by unplugging it from the power outlet for a minute, then plugging it back in. Also, check for and install any available software updates for the TV in the Settings menu.
Ensure 'Game Mode' is enabled in the Picture Settings for the specific input you are using. Verify that your gaming console or PC is connected to an HDMI 2.1 port and that the output resolution and refresh rate settings on your gaming device match the TV's capabilities (e.g., 4K@120Hz/144Hz).
