Frequently Asked Questions

Will a monitor arm damage my desk?

C-clamp mounts are safe for desks 0.4"-2.4" thick. Use the included protective padding. Grommet mounts require drilling a hole but distribute weight better for heavy ultrawide monitors.

Can monitor arms hold ultrawide displays?

Yes, but check weight limits. A 34" ultrawide weighs 15-20 lbs, while 49" super-ultrawides reach 25-30 lbs. Choose arms rated for 25+ lbs (Ergotron LX, Amazon Basics Premium tier).

How do I stop monitor drift over time?

Gas spring arms require periodic tension adjustment using the included hex key. Tighten the spring tension screw (usually located at the arm pivot) every 3-6 months to maintain position hold.

What's better: single arms or dual mount?

Two separate single arms provide more flexibility (independent positioning). Dual mounts save desk space with a central pole but limit positioning range. For mismatched monitor sizes, choose single arms.
