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 middle-links in the chain must include DisplayPort output ports as well as input ports.
Do all monitors support daisy chain?
Can you run 2 monitors off 1 DisplayPort?
DisplayPort Multi-Stream Transport allows you to daisy chain monitors with DisplayPort 1.2 ports. Daisy chaining describes the ability to connect a series of monitors to a single video output port on your computer or docking station.
Can I make a daisy chain with 2 monitors using an HDMI?
HDMI does not support daisy chaining monitors. You may be able to use an addition adapter for your dock to add another monitor such as USB 3.0 to HDMI or a mini-DisplayPort to HDMI adapter but again that would not allow for daisy chaining these monitors.
