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?
