The part I found interesting are the Legion Glasses[0]. From Google:

> Lenovo says you can plug them into any device which can output via USB Type-C with DP Alt mode. The attached cable is 1.2m (3.93ft) long. Due to their simplicity, they are thus compatible with Windows, Android, and MacOS, just like any other USB Type-C monitor.
