Note:
1. Mobile phone wired screen projection: Connect the mobile phone to other display devices through type-C to HDMI, MHL, DP, miniDP, VGA or DVI adapters (expansion docking stations), so that other display devices can display the mobile phone content in real time. Generally, USB3.0 and above protocols are required to support it.
2. Audio signals can be transmitted simultaneously when projecting through HDMI, DP, and other protocols.
