The USB-C to HDMI 2.1 8K Adapter needs a USB-C port that supports video output through DisplayPort Alt Mode. For best results, use a Thunderbolt 4, Thunderbolt 3, USB4, or USB 3.2 Gen 2 port. It works with macOS, Windows 11, 10, and 8, iOS and iPadOS 10.2 or later, and ChromeOS. On Mac, video output tops out at 4K at 60Hz.
