Connecting 2 external screens to MacBook Retina 2015

Hi all,

I am wanting to set up 2 x external screens (HDMI screens) to my MacBook Retina 2015. I have seen in Apple help to go to 'about this mac' > support > specifications > to see how many screens my device will connect too but the page doesn't load, comes up with an error. I've had a look in the user guide and it talks about connecting 1 screen but doesn't mention whether you can or can't connect 2.

Can anyone help?

My MacBook has a USB-C connection so any advice on adaptors I would need for the connection would be appreciated as well. I am thinking about purchasing a docking system of some sort, hopefully one that will also allow my partners HP laptop to connect to the screens as well (not at the same time as mine is connected of course :) )

Thanks in advance!!

Amy
