2017 iMac - 3 Displays?

[gregrose]

Hi All

I want to have 2 external displays running off of 1 USB C port, i bought a dual monitor USB C adapter but I am finding out this will only give me an A B B display, so the two external displays mirror. Is there an adapter that will connect to 1 USB C port that gives you triple monitor function (A B C)?

thank you!

What is the resolution of the displays you are trying to run? TB/USB has bandwidth limits so if they are 1920x1080 you can probably run three off a single port, but if they are QHD or 4K, you will be limited to two or even one.
