Review on 🖥️ StarTech.com USB 3.0 Dual Monitor Mini Dock - DisplayPort 4K 60Hz Video & Gigabit Ethernet - 1ft (30cm) Cable - Portable USB 3.1 Gen 1 Type-A Laptop Adapter (USBA2DPGB) by William Hood

This unit has performed flawlessly and exceeded my expectations. You won't be disappointed, just INSTALL THE DRIVERS for the device or you won't achieve anything; If you got it working without a driver, your overall experience is probably less than ideal. I have a 2017 MacBook Air and Apple itself said that this MacBook will NOT support more than two external displays. You were wrong. What I did to achieve this triple monitor setup (quad display if you count the MacBook monitor, I'm not counting) I used this USB(2) Displayport splitter and a Mini Displayport to Displayport cable. DO NOT use an adapter, instead use a straight cable. The adapter causes serious problems and I strongly discourage anyone from using it. Hope that helps! PS If you've been trying to find any answers or guides on how to use triple external monitors with a MacBook Air or a MacBook, you won't. Well I haven't found anything useful at all. This is because the Thunderbolt 3 port only supports (2) external monitors through each TB3 controller. (MacBooks with 4 ports have 2 separate controllers, so up to 4 displays) By the way, this information ONLY applies to non-Thunderbolt monitors. These monitors can be daisy-chained.
