Know before you buy
Yes, the QN77S90C features a 144Hz refresh rate and Motion Xcelerator technology, making it an excellent choice for smooth, responsive gaming on current-gen consoles and PCs.
While OLED technology is renowned for its perfect blacks and infinite contrast, it performs best in controlled lighting. In very bright rooms, you may notice some reflections, though the display's vibrant color output helps maintain visibility.
Yes, this model has Alexa built directly into the television. You can control volume, change channels, and launch apps using your voice without needing a separate smart speaker.
Yes, it includes Object Tracking Sound Lite with Dolby Atmos support. This creates a more immersive, spatial audio experience that moves sound around the screen to match the on-screen action.
The QN77S90C supports HDR10 for enhanced contrast and color depth. Please note that while it handles high-dynamic-range content beautifully, it does not support the Dolby Vision format specifically.
OLED pixels are self-illuminating, meaning they can turn off completely to produce true black levels. This results in superior contrast and color accuracy compared to traditional LED or LCD screens.
