Monitor Arm Buying Guide
1. VESA Compatibility
Before buying, ensure your monitor has a VESA pattern (usually 4 screw holes on the back, 75x75mm or 100x100mm). Without this, you’ll need an additional adapter.
2. Weight Capacity
Monitor arms use either mechanical springs or gas springs. Gas springs are smoother but have strict weight ranges. Make sure your monitor weight falls within the arm’s minimum and maximum limits.
3. Desk Attachment Type
Most arms use a C-Clamp (grips the edge of the desk) or a Grommet Mount (goes through a hole in the desk). Check if your standing desk has a thick enough edge for a secure clamp.
Frequently Asked Questions (FAQ)
Can a standing desk handle a monitor arm?
Yes, most high-quality standing desks are designed to handle the localized weight of a clamped monitor arm. Just ensure the desk surface is not made of thin glass.
Will a monitor arm save desk space?
Absolutely. By lifting the monitor stand off the surface, you reclaim the area directly underneath the screen for your keyboard, mouse, or documents.
