DisplayPort Multi-Stream Transport allows you to daisy chain monitors with DisplayPort 1.2 ports. Daisy chaining describes the ability to connect a series of monitors to a single video output port on your computer or docking station. This has the benefit of reducing clutter on your desk and simplifying cable management. See the image below for an example of two monitors daisy chained to a laptop.

Before you get started, ensure you have the following:
To connect your personal computer to multiple monitors using DisplayPort MST:
Because your GPU can only output so many pixels, the number of monitors that you can daisy chain together is limited. This limit depends on the resolution, timings, and refresh rates of the connected monitors. See the table below for some basic configuration options.
Display resolution | Maximum number of monitors |
---|---|
1680 x 1050 | 5 |
1920 x 1080 | 4 |
2560 x 1600 | 2 |
3840 x 2160 (Ultra HD, 4K) or 4096 x 2160 (4K x 2K) |
