Why Use a Monitor Arm?
Monitor arms free desk space, allow precise height/angle adjustment, and let you push monitors back for more viewing distance. They're especially valuable for standing desks (the monitor moves with you) and dual-monitor setups (clean alignment).
Types
- Single arm — One monitor. The most common. $30–$150.
- Dual arm — Two monitors on one clamp. Saves a clamp point. $50–$200.
- Ultrawide arm — Heavier duty for 34"+ monitors. Check weight rating carefully. $60–$200.
Key Specs
- Weight capacity — Must exceed your monitor's weight. Check the VESA mount weight, not the total product weight (which includes the stand).
- VESA pattern — 75×75mm or 100×100mm. Most monitors support 100×100.
- Clamp vs grommet — Clamp is easier to install (no drilling). Grommet is more permanent and stable.
- Gas spring vs mechanical — Gas spring allows smooth, one-hand adjustment. Mechanical (friction-based) is cheaper but harder to reposition.
