Know before you buy
Unlike LED TVs that use a backlight, OLED technology uses self-illuminating pixels. This allows the TV to achieve perfect blacks and infinite contrast, resulting in a more vivid and realistic picture quality.
Yes, it is well-suited for gaming. It features a 144Hz refresh rate and Motion Xcelerator Turbo+ technology, which minimizes blur and lag during fast-paced action sequences.
The TV is compatible with both Amazon Alexa and Google Assistant. You can integrate it into your existing smart home setup to control volume, change channels, or launch apps using simple voice commands.
Yes, the processor uses artificial intelligence to upscale lower-resolution content to near-4K quality. It analyzes the image in real-time to enhance detail, reduce noise, and optimize color accuracy.
This TV is compatible with a standard 400mm x 300mm VESA wall mount. Due to the large screen size and the thin Laser Slim design, ensure your mount is rated to support the weight of a 77-inch display.
Yes, it features built-in Dolby Atmos and Object Tracking Sound Lite. While it provides a clear and immersive audio experience, you can also connect a dedicated soundbar or surround sound system via the HDMI ports for an even more robust setup.
