How to Daisy Chain Monitors

Multi-monitor setups are a great way to improve productivity and your gaming immersion, especially if they are large enough to wrap around your peripherals. But not every graphics card or laptop supports the cables you need to send data to those displays, and in some cases, distance from the host system can present problems of its own. That's where daisy-chaining comes in.

Daisy-chaining, officially known as multi-stream transport, or MST (in the case of DisplayPort technology) involves connecting a monitor to another monitor instead of directly to your system’s video out port.

It's a great way of minimizing cable clutter and extending the range of your monitors from the source system. There are some limitations to it since the maximum bandwidth of the single cable between the first monitor and the host system will need to handle the video stream for all daisy-chained displays, but there are plenty of high-end cables to help you daisy chain monitors while making the most of their display resolutions and refresh rates.

Daisy chain monitors are no different from any other monitors. There's nothing special about the displays themselves. It's all about how you manage the cables and Cable Matters has just what you need to make it possible.

Note: USB-C daisy chaining for extended displays is supported on Windows only. On macOS, Thunderbolt 3 is required for extended displays; daisy-chaining through USB-C only will result in mirrored displays.

How to Daisy Chain Your Monitors

To daisy chain your monitors, you need a few specific things.

First, you need two or more monitors that support at least DisplayPort 1.2. Displays that will act as a middle link in the chain must include DisplayPort output ports as well as input ports. You also need DisplayPort cables, preferably high-quality ones, though they can be 1.2, 1.3, or 1.4, generation, they're entirely interchangeable.

Alternatively, you can use USB-C cables, but HDMI cables do not support daisy chain monitors.

DisplayPort is the more established daisy chain medium, as it has been supported since DisplayPort 1.2, which debuted in January 2010. To daisy chain DisplayPort monitors, all you have to do is connect the first display to your host system using a compatible DisplayPort cable, and the second display to the first's secondary DisplayPort output connection.

Note: Some monitors may need you to select the higher-end DisplayPort configuration (at least DP 1.2) to utilize extended monitor modes. Otherwise, you may be restricted to mirror mode, where both displays show the same content.

If your graphics card or laptop supports it, you may be able to increase the number of your DisplayPort daisy chain monitors even further, so that you have three, four, five, or even six displays – although that's typically reserved for the highest of high-end graphics cards. Unless you're running relatively low resolutions across all those screens too, you may start to run into bandwidth issues with the DisplayPort cables. For example, a DisplayPort 1.2 daisy chain can handle four 1080p screens, and two displays running at 2,560 x 1,600. DisplayPort 1.3 and 1.4 can daisy chain DisplayPort monitors up to 4K resolution, though only two of them at the highest resolution and only at 60Hz (even though DisplayPort does support higher refresh rates). They could do up to six 1080p daisy chain monitors, however.

Note: Intel’s current integrated graphics card supports up to 3 displays (this includes the laptop's built-in display). To use 3 independent external displays, you must close the lid of your laptop. 

How to Daisy Chain Your Monitors with USB-C

USB-C connections offer a similar multi-monitor solution to DisplayPort daisy chain technology. It has the option to extend and duplicate displays, useful for different scenarios, and cuts back on cabling while extending the range of your displays from the source system.

This is thanks to USB-C's alternate mode functions. Alternate mode simply allows a video signal to be sent over a USB connection, which was previously reserved for data only. In this case, it's the same DisplayPort 1.4 protocol, but over USB-C instead of the DisplayPort connector.

As well as using a high-quality USB-C cable, you'll also need to use a converter. You can use a cable with DisplayPort connectors, an adapter, or a multi-port hub, depending on your daisy monitor needs. Whichever solution is right for you, though, the USB-C output on the master display, must then output to the DisplayPort connection on the first or subsequent slave displays.

Note: Because DisplayPort cannot provide power for the subsequent displays in your daisy chain, you will need to provide a separate power cable for them, rather than relying on just a single USB-C cable for everything. That can mean the monitor charges your laptop though, which does at least eliminate the charging cable for that device.

Once set up, you shouldn't notice much of a difference with daisy chain monitors that use USB-C instead of DisplayPort. The only difference may be in terms of the maximum resolution or number of monitors you can support using the USB-C connection, as it doesn't have the same bandwidth as DisplayPort 1.4. That may mean running your daisy chain monitors at a slightly lower resolution or refresh rate to maintain full support for your multiple monitors.

Which Cables Do You Need?

For daisy chaining monitors, you’ll need DisplayPort cables to connect the monitors, and a DisplayPort cable to connect your first monitor to your host – either over DisplayPort or USB-C. Cable Matters recommends high-quality DisplayPort 1.4 cables to ensure you’re getting the most feature-rich cable possible. To add a stylish look to your gaming setup and ensure that you're getting the longest life out of your cables, Cable Matters recommends a braided cable. The braided outer cable jacket provides extra flexibility, protecting the cable from kinking. It also adds an extra layer of protection from an unexpected impact damaging the cable core.

  • Hello!

    My laptop has one HDMI port and one Mini-DP port.
    As is written, HDMI port doesn't support daisy chain monitors.
    But what about Mini-DP ports?
    • Hi Francesco,

      As long as your laptop’s MiniDP port supports DisplayPort Multi-Stream Transport (MST), it should support daisy chaining.
  • Hi,

    Looks like that should work! Just make sure your computer supports DP Alt Mode over USB-C. You might also need to enable the "USB Type-C:MST/USB Type-C:SST" mode in your monitor's settings menu. You can find it by opening the On-Screen Dispaly and selecting System > DP OUT.
  • I am using 2 HP monitors that are daisy chained together using Display port. I wish to add a third display but I have used all of the display ports available on the primary input monitor. Is there a way to link my third screen using HDMI? My tower does not have an HDMI Jack. It only has DP which I’ve used all of, and USB
  • Can I link my computer to monitor 1 with HDMI and then link monitor 1 to monitor 2 with DP? Or does it need to be DP all the way?
  • I tried to daisy chain two monitors following this guide. The second monitor says "DP No Input", while both cables are correctly connected. What could cause this?
  • Hi,

    I have a Dell Laptop www.dell.com/.../vostro-15-5502-laptop
    Connections: 7. HDMI 1.4b | 8. USB 3.2 Type-A port | 9. USB 3.2 Gen 2 Type-C™ (DP/PowerDelivery)

    Currently,

    I have 3 monitors
    (1). Dell Ultrasharp DC2719C - USB -C Connection / Power to Laptop - 1440p
    (2). Old AOC 21" Monitor - Daisy Chain Display Port Cable from (1) - 1080p
    (3). Asus Proart 24" - HDMI Connection (Direct) - 1080p

    I would like to upgrade my monitors (2) and (3) and add a (4) and looking at some lower price range 24-27" Monitors 1440p preferable, Dells, and any other brand as long as it's thin bezeled, and thinner / newer, that could connect my 4 monitors together.

    I believe USB-C can be daisy chained up to 6 monitors 1080p (is that correct?) Preferable 1440p.

    What's the best way for me to upgrade my configuration to allow it to be powered from the laptop?
    Do I need a laptop dock?

  • I have a Macbook Air Silicon laptop and a Dell laptop, and I've just recently gotten a second monitor. My Dell has a USB-C DP port and my Macbook has whatever kind of USB-C Macbooks have. I can connect both of my laptops to my monitor which supports USB-C. Can I then just connect a DP cable from my primary monitor to my secondary monitor and extend the display? Would it work for both laptops or just for the Dell?
  • Can the first connection from the laptop to monitor be usb-c then the second connection from the master monitor to the slave monitor be DisplayPort?
    • Yes it can, currently works this way on my table.
  • My laptop has one USB-C port with DP alt mode.

    I'm considering buying a 2 pieces of a USB-C monitor with these ports:
    DisplayPort 1.2 x 1, HDMI 1.4 x 1, USB-C 3.2 Gen 1 x 1 (upstream, power delivery up to 65W)

    If I buy those monitors, can I daisy-chain them like this?

    LAPTOP <--> usbc <--> MONITOR1 <--> displayport <--> MONITOR2
    • Dan
      Did this solution ever get confirmed to work?

      LAPTOP <--> usbc <--> MONITOR1 <--> displayport <--> MONITOR2
  • Hi,

    Is it possible to daisychain from the DP-out port on monitor 1 to hdmi-in on monitor 2? I've seen displayport to hdmi cables and I was wondering if this setup would work. Monitor 1 is connect to my laptop with an usb type c cable.
  • Hi

    just wondering, i am having lag issues with my mouse when running a couple of samsung 27 inch monitors daisy chained from an HP envy laptop. I am using a USB-C cable between laptop and first screen.

    I think i need to invest in a better quality USBC cable, but are you suggesting in the above article i would be better to use a converter or USBC to DP cable to go straight into the DP IN port of the first monitor?

    Cheers MT
  • I've got two Dell monitors that are daisy chained and working fine with monitor 1 connected to laptops via mini display port cable. I'm about to switch to apple mac and understand that I have to get usb-c to mini display port cable to connect to monitor 1. Will the daisy chaining still work?

    thanks
  • Hello- this is a year late, so hopefully someone still monitoring the feed.

    I understand the technology, but I can't seem to find monitors that have both a display port and out (I need three monitors connected).

    Can you recommend some?
