How do I set up a monitor arm for a dual-screen laptop and external monitor combo?

The most ergonomic dual-laptop-and-monitor setup uses the external monitor as the primary screen (at eye level on a monitor arm) with the laptop on a laptop stand or raised platform beside it. The laptop screen serves as the secondary display. For this setup: place the external monitor arm to the left or right of the laptop position, align the top of both screens to a similar height, and use the laptop keyboard and mouse at elbow level. Alternatively, a laptop tray arm (a secondary arm with a shelf for the laptop) can raise the laptop screen to match the external monitor height, eliminating the height mismatch.
