You can daisy chain any monitor, but only if that monitor has the right ports and your graphics card supports it.
That’s the honest answer, and it’s not as simple as just plugging one display into another.
Daisy chaining is a feature that requires specific hardware on both the monitor and your computer.
If you’ve been wondering whether you can daisy chain any monitor, the short version is that only certain monitors are built for it.
But don’t worry, I’m going to break down exactly what you need to know so you can figure out if your setup is ready for this trick.
In this post, we’ll cover why you can’t daisy chain any monitor, what makes a monitor daisy-chain capable, and how to set it up if you have the right gear.
Let’s dig into the details.
Why You Can’t Daisy Chain Any Monitor
The biggest reason you can’t daisy chain any monitor is that this feature depends on a technology called DisplayPort Multi-Stream Transport, or MST.
MST is what allows a single video output to carry multiple display signals through a chain.
If your monitor doesn’t have MST built in, it simply won’t pass the signal along to the next screen.
So while you might think any monitor can daisy chain, the reality is that this capability is reserved for displays that explicitly support MST.
Let me explain what that means for your specific monitors.
1. DisplayPort Is the Only Real Option
Daisy chaining any monitor is only possible through DisplayPort connections.
HDMI doesn’t support daisy chaining in the same way, and most monitors don’t have the required ports for it anyway.
You’ll need a monitor with at least one DisplayPort input and one DisplayPort output.
The output port is what lets you connect the next monitor in the chain.
If your monitor only has DisplayPort inputs, you can’t daisy chain it because there’s no way to send the signal out to another screen.
2. MST Support Is a Must
Even if your monitor has both DisplayPort in and out, it still needs to support MST.
MST is the technology that splits the video signal into multiple streams.
Monitors without MST will not recognize the daisy chain setup.
You can check your monitor’s specs online or look for “MST” or “DisplayPort 1.2” in the manual.
If your monitors lack MST, then you can’t daisy chain them, and you’ll need a different solution like a hub.
3. Graphics Card Limitations
Your computer’s graphics card also plays a huge role in whether you can daisy chain any monitor.
Most modern GPUs support MST, but older ones might not.
You also need to check how many displays your GPU can handle at once.
If your graphics card only supports two monitors, then daisy chaining a third won’t work.
The GPU sends a single signal through the first monitor, and that monitor passes it along.
So if your GPU can’t handle the total number of monitors, the chain will fail.
What Monitors Can Daisy Chain Successfully
Now that you know why you can’t daisy chain any monitor, let’s talk about which ones actually work.
Monitors that can daisy chain are typically marketed as having MST or DisplayPort 1.2 or higher.
You’ll often find this feature on business and professional displays, like the Dell UltraSharp series or certain LG and Samsung models.
These monitors have the required output port and the internal chipset to handle multi-stream transport.
If you’re shopping for new monitors, look for “DisplayPort out” in the specifications.
That’s a clear sign that the monitor is designed to daisy chain.
1. Check Your Monitor’s Ports
Before you try to daisy chain any monitor, take a close look at the back of each display.
You’ll need a DisplayPort output, which is often labeled “DP Out” or just “Output.”
If you only see DisplayPort inputs and no output, then your monitor can’t daisy chain.
Some monitors use USB-C for daisy chaining, which is great if they support DisplayPort Alt Mode.
But USB-C daisy chaining works differently and requires even more specific hardware.
2. The First Monitor in the Chain
In a daisy chain setup, the first monitor connects directly to your computer.
That monitor must have MST enabled, and it needs to support the full resolution and refresh rate you plan to use.
The second monitor connects to the first one via a DisplayPort cable.
You can usually chain up to four monitors, depending on your GPU’s bandwidth.
But remember, you can’t daisy chain any monitor if even one in the chain lacks MST support.
3. Resolution and Refresh Rate Limits
Even when monitors support daisy chaining, bandwidth is a real constraint.
If you’re running two 4K monitors at 60Hz, the DisplayPort connection might not have enough bandwidth.
That means you might need to lower the resolution or refresh rate to make the chain work.
This is another reason why you can’t daisy chain any monitor, because the limits aren’t just about ports.
You have to balance the total data being sent through the single cable.
How to Set Up Daisy Chaining on Supported Monitors
If you’ve confirmed that your monitors can daisy chain, setting it up is fairly straightforward.
Here’s a step-by-step guide to get you going.
1. Connect the First Monitor to Your PC
Use a DisplayPort cable to connect your computer’s graphics card to the DisplayPort input on the first monitor.
Make sure your GPU drivers are up to date before you begin.
Older drivers might not handle MST properly.
2. Connect the Second Monitor to the First
Now take another DisplayPort cable and connect the “DP Out” port on the first monitor to the “DP In” port on the second monitor.
Repeat this for additional monitors if your setup supports it.
3. Enable MST on Your Monitors
Many monitors have an on-screen menu where you can turn MST on or off.
Check the settings on each monitor and enable MST if it’s not already active.
Once enabled, your computer should detect all monitors in the chain.
4. Configure Display Settings in Your OS
On Windows, right-click your desktop and select Display Settings.
You should see multiple displays listed, and you can arrange them however you like.
On macOS, go to System Preferences and then Displays.
The process is the same once the chain is recognized.
So, Can You Daisy Chain Any Monitor?
You can’t daisy chain any monitor because only those with DisplayPort output and MST support will work.
Daisy chaining any monitor comes down to having the right hardware on every single display in your setup.
If even one monitor lacks the required ports or MST chipset, the whole chain falls apart.
So before you buy new monitors or try to hook up your existing ones, check the specs and look for that crucial DisplayPort out port.
With the right gear, daisy chaining is a super clean way to reduce cable clutter and expand your workspace.
But if your monitors don’t support it, you’ll need to fall back on a docking station or a video splitter instead.
Hope this clears up whether you can daisy chain any monitor, and now you know exactly what to look for to make it happen.
