Hello, I just ordered a new 2017 27" iMac and would like to use my 2 27" monitors (Acer G6 G276HL) that
I currently have. I have hoping to use 2 of the USB 3 ports saving the Thunderbolt 3 ports for storage. I have looked for a USB 3 to DVI or VGA adapter and can't seem to find compatible ones. Any adapters I find even in usb-c for DVI or VGA say they are not compatible with 2017's iMac. I know apple sells a usb-c to vga, but I would rather not use that port, nor pay $70 for the adapter. Has anyone connected their DVI or VGA displays to their new 2017 iMac using a usb 3.0 port?

I used a Cable Creations USBC to VGA adapter and it works fine, but that's USBC. I wonder if it would work if you attached a USBC to USB connector. Or must it use DisplayPort conversion, out of USBC?

I bought two of the below adapters for my two external monitors. One is daisy chained through a TB3 storage device. Everything works fine. If you're using the TB3 ports for storage, just put the monitors at the end of a chain.

Great, Thanks. I will try these. Since this will use up both Thunderbolt 3 ports, how can I hook up my TV that is connected via HDMI without having to unplug something? Has anyone tried using a USB 3 to HDMI on the new iMac's?
