Your computer, tablet, or phone needs a USB-C port that supports DisplayPort Alternate Mode (DP Alt Mode) over USB-C. Without it, the Satechi Core USB-C to 4K HDMI Adapter cannot send video to your display.

Ports that work with the adapter: Thunderbolt 3, Thunderbolt 4, USB4, and USB-C 3.2 Gen 2. Once connected, your display mirrors or extends your screen depending on your operating system settings.
