VESA pattern compatibility is the first thing to check
Monitor arms mount via standardized VESA hole patterns (commonly 75x75mm or 100x100mm) — confirm your specific monitor supports one of the patterns the arm lists before buying, since not all monitors (especially ultrawide or older models) use standard VESA mounting.
Weight capacity needs real headroom, not an exact match
An arm rated right at your monitor's exact weight may not hold position well or may drift down over time. Look for a rated capacity comfortably above your monitor's actual weight for reliable, stable positioning.
Clamp vs. grommet mounting depends on your desk
C-clamp mounts attach to the desk edge and work on most desks without drilling; grommet mounts go through a hole in the desk for a cleaner look but require your desk to have (or allow) a grommet hole. Check which mounting style your desk can actually accommodate.
Gas spring vs. friction-arm adjustment changes day-to-day usability
Gas spring arms let you reposition the monitor with light one-handed adjustments; friction-arm designs are simpler but may require more force or loosen over time. If you adjust position often, gas spring designs are generally more convenient.
Will a monitor arm fit any monitor?
Only if your monitor has a compatible VESA hole pattern, most commonly 75x75mm or 100x100mm, and its weight falls within the arm's rated capacity. Check both specs before buying, since not every monitor supports standard VESA mounting.
Clamp or grommet mount for my desk?
C-clamp mounts attach to the desk edge and work without drilling, fitting most desks. Grommet mounts need a hole in the desk but can look cleaner. Choose based on what your specific desk allows or already has.
Do I need a gas spring monitor arm?
If you reposition your monitor frequently, gas spring arms make one-handed adjustment easier. If you set the position once and rarely change it, a simpler friction-arm design may be sufficient.
