How do I adjust a monitor arm correctly for a sit-stand desk?

On a sit-stand desk, the monitor arm must be readjusted each time the desk height changes. For the seated position: the top of the monitor should be at or slightly below eye level when sitting with the spine upright — for most adults, this means the monitor center is 18"–24" from the desk surface. For the standing position: raise the monitor arm so the monitor top is at or slightly below standing eye level. A gas-spring arm allows quick height adjustment with a single hand motion, making the seated-to-standing transition practical. Set the arm's spring tension to match your monitor's weight so it stays in position without drifting.
