    To use this method, your monitors must have DisplayPort v1.2 or higher In and Out ports. Additionally, your laptop must have either a DisplayPort Out port or a USB-C port that supports DisplayPort. [1]
    • If your monitors were purchased after 2010 and each have a DisplayPort In and Out port, you should be able to daisy chain them.
    • If your laptop has a USB-C port, confirm it supports DisplayPort , then make sure you have a USB-C to DisplayPort cable.

    To daisy chain with Thunderbolt or USB-C cables, one of your monitors must have two Thunderbolt ports, while your laptop and other monitor only need one port.
    • Thunderbolt and USB-C ports use the same connectors, so if your laptop has a USB-C port that can output video , that will work too!

    Connect the two monitors with a Thunderbolt or USB-C cable. All Thunderbolt ports have the capacity to both input and output video, so if your monitor has multiple ports, it does not matter which port you use. [4]
    • If your monitor instead has USB-C ports, make sure you are using a port that supports video input and output. You can try to verify this by looking up the specifications of your monitor and checking to see if the ports support “Alt Mode”.

    Depending on your laptop, your dock will need to use different connectors. For example, if your laptop has USB-C ports, your dock should connect via USB-C. Additionally, make sure the video output ports are compatible with your monitors, or that you have the appropriate adapters.
    • Some laptops connect to docking stations by sitting on top of the station, then being locked into place, so there will be no connecting cable.

    If your laptop has multiple ports and you do not want to or are unable to daisy chain, you can simply connect a port to each monitor.
    • Make sure that the ports are compatible with those on your monitor. If they are not compatible, you will need to purchase adapters, such as USB-C to HDMI, or cables with different connectors, such as an HDMI to DisplayPort cable.

    Set up your displays so they work best for you. Your digital workspace is now ready! [9]
    • Both Mac and PC have an option to allow you to view the number of each monitor. That way, you can then see the numbers on the little picture inside the screen and you can also see them on the physical monitors. You can then drag the monitors around with your mouse and put them in exactly the orientation they are in your screen. For instance, if one is two inches higher than the other ones, put it two inches higher on the screen so things work smoothly between them.
