The USB-C to HDMI 2.1 8K Adapter connects a USB-C computer, tablet, or phone to an HDMI display, so you can mirror or extend your screen to a monitor, TV, or projector. Using HDMI 2.1, it supports ultra-high-resolution video up to 8K at 60Hz, or 4K at 120Hz for smoother motion, on compatible devices and displays.
