What is DisplayPort Daisy Chaining?

DisplayPort daisy chaining is a feature that enables you to connect multiple monitors to a single DisplayPort output on a computer or other device. This is achieved through the use of special multi-stream transport (MST) hubs or displays that can split the DisplayPort signal, allowing you to connect multiple monitors in a daisy chain configuration.

Unlike traditional display connections, such as VGA or HDMI, DisplayPort is capable of transmitting multiple audio and video streams over a single cable. This makes it an ideal technology for multi-monitor setups, as it eliminates the need for multiple video outputs on the computer or device.

How Does DisplayPort Daisy Chaining Work?

To understand how DisplayPort daisy chaining works, let’s take a closer look at the anatomy of a DisplayPort connection. A standard DisplayPort connection consists of four main components:

• DisplayPort transmitter: This is the output on your computer or device that sends the video signal to the monitor.
• DisplayPort receiver: This is the input on the monitor that receives the video signal from the transmitter.
• DisplayPort cable: This is the cable that connects the transmitter to the receiver.
• MST hub or display: This is the component that enables daisy chaining by splitting the DisplayPort signal into multiple streams.

When you connect a multi-stream transport (MST) hub or display to your computer or device, it acts as a repeater, amplifying and re-transmitting the DisplayPort signal to multiple monitors. This allows you to connect multiple monitors to a single DisplayPort output, creating a daisy chain configuration.

Here’s how it works in practice:

1. Connect the MST hub or display to the DisplayPort output on your computer or device.
2. Connect the first monitor to the MST hub or display using a DisplayPort cable.
3. Connect the second monitor to the first monitor using another DisplayPort cable, and so on.
4. The MST hub or display splits the DisplayPort signal into multiple streams, transmitting each stream to a separate monitor.
5. Each monitor receives its own unique video signal, allowing you to extend your desktop across multiple screens.
