This 3-port HDMI 2.1 ultra-high performance switch is tailored for premium 8K home theater and high-refresh gaming setups. It solves the shortage of TV HDMI ports by allowing three devices to share one display, eliminating frequent cable plugging and unplugging. Built with full-speed HDMI 2.1 chip with 48Gbps bandwidth, it delivers crystal-clear 8K@60Hz ultra HD images and tear-free 4K@120Hz gameplay. It perfectly passes HDR10 and Dolby Vision dynamic color, and complies with HDCP 2.3 to avoid black screen issues when playing streaming and Blu-ray content. Two easy switching ways are available: the included IR remote lets you switch sources with one click from your sofa; a front physical button serves as backup control. Visible LED lights clearly display which input channel is working. No driver needed, just plug and play directly. It works flawlessly with PS4, PS5, Xbox series, Roku, Apple TV, Fire Stick, Sony QLED/8K TVs, Blu-ray players and projectors. Compact anti-interference housing ensures stable long-hour signal transmission without lag or flicker, ideal for gaming stations and living room entertainment centers.
