Question
Which of the following display types is bidirectional?
- A. DisplayPort
- B. VGA
- C. DVI
- D. USB-C Correct
Explanation
USB-C is a bidirectional interface: the same port and cable can carry video out, data in both directions and power in either direction (for example, a monitor that also charges the laptop and acts as a USB hub). VGA, DVI and DisplayPort carry the video signal one way, from the source to the display.
