Can a monitor arm rotate a screen from horizontal to vertical orientation?

Most commercial monitor arms include a full 360-degree rotation point at the monitor mount, which makes it easy to switch from landscape to portrait mode for document editing, coding, or browsing long pages. Confirm the arm's specs show ±90-degree portrait/landscape rotation. Also check that the arm has enough height range to accommodate the monitor's taller footprint in portrait orientation — this catches people off guard.
