I currently own a MBP (2016, 13", No Touch Bar) as well as an official Apple USB-C Digital AV Multiport Adapter (HDMI version). I have a second screen plugged in (Asus VS247H, HDMI, 24" 1080p), and everything works OK.
I was wondering if I could buy another identical adapter to plug a third screen (same as the second) and then have a triple screen setup : MBP screen + 2 external monitors ? I would like to avoid buying another 80€ adapter if it will not work. In such case, would anyone know of a viable solution for achieving this ?
