After several attempts and countless hours of watching videos on YouTube, I found out that the M1 supports dual displays. It worked *instantly*. First, make sure you have the DisplayPort drivers installed. When you connect your device for the first time, you may need to unplug and plug it back in. The power button glows blue when no monitors are detected and green when they are. SO GOOD TO HAVE TWO MONITORS. I'm not sure why this couldn't be supported at launch.
