Built-in 2.1 channel audio with dedicated subwoofer

Setup, Compatibility & Care

Due to its 100-inch size, it is highly recommended to have two or more people available for unboxing and installation. The unit utilizes a VESA mount pattern of 800 x 400 mm for wall mounting; ensure your wall bracket is rated to support the 50kg+ weight of the display.

For connectivity, the TV offers dual-band Wi-Fi and Ethernet LAN for stable streaming. Bluetooth 5.0 is built-in for connecting headphones or external soundbars. Keep the screen clean by using only a dry, soft microfiber cloth to prevent static buildup or scratches. Periodically check that all cables are securely seated in the HDMI 2.1 ports to maintain full 4K 144Hz bandwidth.
