Frequently Asked Questions

What is the M2.1 monitor arm’s supported monitor weight range?

Humanscale’s transition comparison lists M2.1 for monitors weighing 5 to 15.5 lb. The newer M2 Pro is a different model with a 5-to-22-lb capacity, so do not use M2 Pro’s upper limit when sizing an M2.1.

How can I tell an M2.1 apart from an M2 Pro?

Humanscale says M2.1 uses a green counterbalance indicator, while M2 Pro uses a red indicator. The upgrade guide also identifies M2.1 as the legacy model and M2 Pro as its latest compatibility in the transition table.

What adjustment and cable-management features does M2.1 provide?

The M2.1 product page describes a Compensator Mechanism and self-lubricating precision bearings for monitor adjustment, along with top-to-bottom cable management. It also describes Smart Stop and a built-in Counterbalance Indicator for setup and positioning.

Is the M2.1 compatible with Humanscale M/Connect 2 or M/Power?

Humanscale’s M2.1 page states that the arm is compatible with the M/Connect 2 docking station and with M/Power, a USB Type-A and Type-C charging station. These integrations are useful when consolidating desk cables and device charging.

What warranty applies to the Humanscale M2.1?

Humanscale’s warranty table lists 15 years for M2.1 monitor arms. The warranty is for the original customer, is non-transferable, and requires purchase from Humanscale or an authorized third-party vendor; requests use a Support Ticket with the original order or purchase-order number.
