To do a daisy chain, you connect multiple devices together in a series using a single cable run from one device to the next, which is a straightforward way to expand your network without needing a separate switch for each connection.
This method is incredibly handy when you have limited ports or want to reduce cable clutter behind your desk.
You can daisy chain a variety of gear, from computers and monitors to your favorite gaming consoles and even some smart home devices.
In this post, we’ll walk through exactly how to do a daisy chain correctly, looking at the different types, the best practices to follow, and the common pitfalls you’ll want to avoid.
Let’s jump right in and get your setup connected neatly and efficiently.
How to Do a Daisy Chain: The Core Concept
The first thing to understand when learning how to do a daisy chain is the fundamental flow of data, because it’s all about passing information along a line.
In a daisy chain, device A connects to device B, device B connects to device C, and so on, so it’s a linear topology rather than a hub-and-spoke arrangement.
Each device in the chain acts as a repeater or a pass-through, taking the signal from the previous device and forwarding it to the next one.
This means you can daisy chain effectively with almost any device that has both an input and an output port for the same type of signal.
Let’s explore the main scenarios where you’ll likely want to daisy chain, starting with the most common one.
1. Daisy Chaining Monitors for a Multi-Screen Setup
One of the most popular reasons to daisy chain is to set up multiple monitors with a single cable connected to your computer.
A daisy chain of monitors works best when you use DisplayPort connections, especially the 1.2 version or later, because it supports Multi-Stream Transport (MST).
To daisy chain monitors, you plug your computer’s DisplayPort output into the first monitor’s DisplayPort input.
Then, you take another DisplayPort cable and run it from the first monitor’s DisplayPort output (often labeled “MST” or “Out”) to the second monitor’s input.
You can keep this going for a third monitor, and each monitor needs to support MST for this to work smoothly.
If you’re using HDMI, a daisy chain is much trickier because standard HDMI doesn’t natively support this daisy chain style of daisy chaining.
You’ll need to use a special splitter or a docking station to achieve a similar multi-monitor setup with HDMI.
2. Daisy Chaining Hard Drives and Storage Devices
If you’re running out of storage ports on your computer, you can daisy chain external hard drives using Thunderbolt or USB-C connections.
To do a daisy chain with storage, you connect your computer to the first drive, then connect the first drive to the second drive.
This daisy chain method works fluently with Thunderbolt 3 and Thunderbolt 4, which can support up to six devices in a single series.
Each drive in the chain needs two Thunderbolt ports, one for the incoming connection and one for the outgoing connection to the next drive.
USB-C with USB 3.1 or 3.2 generally does not support daisy chaining, so you’ll need to stick with Thunderbolt for this type of daisy chain.
3. Daisy Chaining Audio Gear and Instruments
Musicians and audio engineers often daisy chain MIDI devices, like synthesizers and drum machines, to sync them together.
When you daisy chain MIDI gear, you connect the MIDI Out of the first device to the MIDI In of the second device.
Then, you connect the MIDI Thru or MIDI Out of the second device to the MIDI In of the third device.
This allows you to control all your instruments from a single master keyboard, and the daisy chain keeps all the notes perfectly in time.
You can also daisy chain some powered speakers, which usually have a dedicated output to pass the audio signal along to the next speaker in line.
Best Practices for a Reliable Daisy Chain
Knowing how to do a daisy chain is one thing, but doing it reliably is another, and a few simple habits will keep your signal strong and your performance solid.
The most important rule is to limit the number of devices in your daisy chain.
For most connections, you shouldn’t daisy chain more than three or four devices, as signal degradation becomes a real risk.
Exceeding this limit can lead to flickering screens, slow data transfer, or even complete dropouts in the middle of a task.
Another best practice is to always use high-quality, certified cables that are properly shielded, since cheap cables are often the weakest link in a daisy chain setup.
Keep your cable runs as short as possible, especially for high-resolution video, because every extra foot of cable adds resistance and potential for interference.
Finally, make sure each device is powered correctly, because a power-hungry device at the end of a daisy chain might not receive enough power through the data connection alone.
Understanding the Way of a Daisy Chain
Before you start, double-check that every device you want to include actually supports daisy chain functionality.
Some monitors have a DisplayPort output, but that doesn’t always mean they can pass video through, so you’ll want to check your user manual.
You might also need to enable the MST setting in your monitor’s on-screen display menu for the daisy chain to work properly, and this step is easy to miss.
For Thunderbolt storage, verify that the enclosure is daisy-chain capable, as some cheaper drives are simple hubs that don’t support this feature.
It’s also a good idea to update the firmware on your devices, as manufacturers often fix daisy chain bugs with new releases.
Common Mistakes to Avoid When You Daisy Chain
As you learn how to do a daisy chain, you’ll likely run into a few classic mistakes, and knowing them in advance will save you a ton of frustration.
The biggest mistake is trying to daisy chain devices that simply don’t support it, which leads to a whole day of troubleshooting with no success.
Another common error is using the wrong cable altogether, like trying to daisy chain monitors with a standard HDMI cable and expecting it to carry signals to multiple screens.
Don’t skip the step of checking the port labels, because sometimes the output you think is there is actually a pass-through that won’t separate the signal.
Finally, remember that you can’t create a loop in your daisy chain, so never connect the last device back to the first one, as this will cause a network storm and bring everything down.
Avoiding these mistakes will make your daisy chain experience smooth and worry-free.
So, How to Do a Daisy Chain? It’s Easy Once You Know the Basics
You can do a daisy chain successfully by connecting devices in a series, passing the signal along from one unit to the next with the correct cables and supported ports.
It’s a clean, cable-friendly way to set up extra monitors, expand storage, or sync your audio equipment with just a few simple moves.
Remember that a daisy chain works best when you keep the line short, use quality cables, and verify that each device supports this exact connection type.
So whether you’re building a triple-monitor battle station or adding another drive to your editing rig, you now have the knowledge to daisy chain like a pro.
Now go ahead and get those connections going, and enjoy the simplicity of a daisy chain done right.
