Explanation
DisplayPort supports Multi-Stream Transport (MST), which allows multiple monitors to be daisy-chained from a single port, making it the most space-efficient interface for multi-monitor setups.
Common mistakes.
- A. VGA is an analog interface with a large 15-pin D-Sub connector that supports only one monitor per port and cannot daisy-chain displays.
- C. HDMI does not natively support daisy-chaining or MST, so each monitor requires its own dedicated HDMI port on the graphics card.
- D. DVI uses a large connector, supports only one monitor per port, and lacks the MST capability required for single-cable multi-monitor daisy-chaining.
