Review on 💻 USB 3.0 to VGA Adapter with DisplayLink Chipset - CableCreation VGA to USB External Video Card, 1080P Support, Windows/Mac Compatible by Tim York

When it works, it works great. works with macOS High Sierra (as detailed on the DisplayLink website) - also note that OS updates may disable it entirely. The last update (10.13.4) did this. They say they reported it to Apple and we're waiting. Disappointing, but not entirely their fault. I'm just posting this so you know what you're getting into. If you want to keep software up to date, most likely it won't always "just work".
