All you need is to connect the display port to your monitor and daisy chain it with another one to get a dual surround monitor experience as the Thunderbolt one can do it but I’d stick to the display port.

how can  i do it with thunderbolt ??  is it even possible ? do i need to buy usb c to hdmi cable ?

Well thunderbolt is based off of DisplayPort and the technology to configure multiple monitors together is daisy chaining where you can get up to 3 monitors with 1 cable.

Hello, Can you please explain the process. I am noob. sorry for any trouble
