Can a monitor arm hold a monitor in portrait (vertical) orientation?

Yes — most commercial monitor arms allow the VESA mount head to rotate 90° to landscape or portrait orientation. Portrait mode (vertical) is popular for document review, coding, and chat applications where a tall, narrow screen format is more efficient. Ensure your monitor's VESA mount allows portrait rotation (most do) and that the monitor's on-screen display can be set to rotate the image 90° to match. Gas-spring and multi-joint arms handle portrait-mode well because the arm can be adjusted to center the monitor at the appropriate height for the taller format.
