Fast, smooth motion with a Native 144Hz Refresh Rate keeps live games, fast-paced movies, and competitive gaming sharp and easy to follow, while the Built-in Subwoofer adds deeper, more powerful sound that pulls you into the action.

With Dolby Vision, Dolby Atmos, a full suite of HDR formats, and built-in Fire TV with Alexa voice control, it’s a premium, all-in-one way to enjoy a bigger, more immersive entertainment experience any time of day.
- Hi-QLED MiniLED: Striking contrast and vivid, lifelike color put every scene in a new light. Whether it's a sunny landscape or a candlelit drama, the picture leaps off the screen.
