什麼是 Alt 模式下的 DisplayPort?

DisplayPort Alt Mode (DP Alt Mode) allows a USB-C equipped computer to connect directly to a display or monitor. The monitor will need to have a USB-C port for you to make this connection. You can still use a USB-C equipped laptop with monitors that have more traditional video ports, such as VGA, DVI, HDMI, and DisplayPort but you will need to get a USB-C video adapter.

What do I need to know before using DisplayPort over Alt Mode?

  • Confirm your device’s USB-C port supports DP Alt Mode
  • Read the tech specs on the USB-C video adapter to ensure it supports the resolutions and refresh rates you want
  • If you are interested in a USB-C MST video adapter or laptop docking station, make sure your video card also supports MST

DisplayPort Over USB C Technical Details

DisplayPort leverages the Alternate Mode Functional Extension of the USB Type-C interface, and shares similar electrical characteristics with USB 3.1, allowing use of common system elements. 

  • Video, SuperSpeed USB and power, all on one connector
  • 4K @60Hz 24-bit color (without compression) with simultaneous USB 3.1
  • 5K (5120 x 2880) display support without compression with simultaneous USB 2.0
  • Support for BT.2020 color space, HDR, and HDCP 2.2
  • 8K x 4K display support with use of 4:2:0 pixel structure (good) or VESA Display Stream Compression (better)
  • High-end multichannel audio support
  • Backward compatible with VGA, DVI, and HDMI 2.0 with CEC using plug adapters or adapter cables
  • Extensible packet-based data structure
