One screen is a cage. You've got the spreadsheet on the left, the email on the right, and the video call in a tiny window you keep losing track of. This adapter splits your single USB-C port into two HDMI outputs, a 100W charging pass-through, and a headphone jack. Run two 4K@30Hz displays side-by-side, or one at 4K@60Hz when you only need the big canvas. MST means true extended desktop on Windows – not just a mirror. On macOS it'll drive one extended screen. Aluminium body, 10 cm tail, no drivers. Plug in, extend, get back to work
