Q1: What is Multi-Stream Transport (MST)?

A1: Multi-Stream Transport (MST) is a technology embedded in the DisplayPort (DP) 1.2 and later standards. It allows a single DP output from a computer or laptop to drive multiple independent displays by multiplexing several video signals into one stream.

Q2: How does MST work?

A2: MST combines multiple video signals at the source (e.g., GPU) into a single stream transmitted over a DisplayPort cable. This stream is then split by an MST hub or daisy-chained monitors, each receiving its designated signal.

Q3: What are the connection options for MST?

A3: MST supports two primary methods:

Daisy-chaining: Monitors with DP output ports are connected in series, with the first linked to the source.

MST hubs: A central hub connects to the source and distributes signals to multiple displays, offering flexibility for non-DP monitors.

Q4: What are the benefits of using MST?

A4: MST simplifies multi-display setups by reducing cable clutter, optimizing space, and lowering costs. It enables extended desktops, mirrored screens, or video walls efficiently.

Q5: What are the technical requirements for MST?

A5: Requirements include:

A DP 1.2+ compatible source (GPU/laptop) and cables.

Monitors supporting DP 1.2 with input/output ports for daisy-chaining or an MST hub.

Windows OS (macOS, Linux, and ChromeOS are unsupported).

Q6: How many displays can MST support?

A6: MST can drive up to four 1080p displays or two 4K displays simultaneously, depending on bandwidth limitations (up to 21.6 Gbps for HBR2) 57.

Q7: Are there any limitations or challenges with MST?

A7: MST may face issues with non-Windows OS compatibility, bandwidth constraints for high-resolution displays, and potential chain disruptions in daisy-chained setups if one monitor fails.
