- Monitors must have at least two Thunderbolt ports or a mix of one Thunderbolt and one DisplayPort
- Your laptop must have a DisplayPort, a USB-C port with DisplayPort Alt Mode, or a Thunderbolt port.
Here is how to daisy chain using Thunderbolt ports.
Step 1: Power on all the devices in the setup.
Step 2: Plug the Thunderbolt (USB-C) cable into the Thunderbolt ports of your laptop and the first monitor.
Step 3: Plug the other Thunderbolt cable into the Thunderbolt ports of your two monitors.
To daisy chain via DisplayPort, follow the instructions below.
Step 1: Power on all the devices in the setup, and activate the DisplayPort 1.2 or MST feature on your monitors.
Step 2: Plug the Thunderbolt (USB-C) cable into the Thunderbolt ports of your laptop and the first monitor.
Or plug the DisplayPort cable into your laptop’s DisplayPort Out and the first monitor’s DisplayPort In.
Step 3: Plug the DisplayPort cable into your first monitor’s DisplayPort Out and the second monitor’s DisplayPort In.
