new AOC external monitor e1659fwu
I saw lots of posts about the AOC external monitor not working. I had to tinker with it a bit and I finally figured it out.
1. Download the latest driver from http://www.displaylink.com/downloads/file?id=1085
2. Ensure that you download the driver for your specific operating system.
3. Restart your computer.
4. After installation, macOS may require the DisplayLink system extension to be enabled in System Preferences -> Security & Privacy -> General. Click on Allow and restart the system.
5. Your external monitor should work.
