How to Set Up Monitor Arms on a Desk
Monitor arms free up desk space and provide superior ergonomic positioning compared to built-in monitor stands. This guide covers both clamp-style and grommet-hole mounting methods for single and dual monitor configurations.
- Choose your mounting method. Determine whether to use clamp mounting or grommet mounting. Clamp mounts attach to your desk edge and work with any desk thickness from 0.4 to 2.4 inches. Grommet mounts require drilling a hole through your desk but provide a cleaner look and work better with glass or metal surfaces.
- Verify monitor compatibility. Check that your monitors support VESA mounting patterns. Look for four screw holes on the back of each monitor in a square pattern. Common VESA sizes are 75x75mm, 100x100mm, or 200x200mm. Remove the existing monitor stand by unscrewing the VESA screws and lifting it away.
- Position the base on your desk. For clamp mounts, position the base so the clamp sits flush against your desk edge with the arm extending over your workspace. For grommet mounts, mark the center point where you want the arm positioned and drill a hole using the provided template. The hole typically needs to be 0.5 to 1 inch in diameter.
- Secure the mounting base. Tighten the clamp mechanism or insert the grommet post through your drilled hole. For clamps, turn the tension knob clockwise until the base feels completely secure with no movement. For grommet mounts, thread the locking nut from underneath and tighten with the included tool.
- Attach monitors to the arm brackets. Connect each monitor to its bracket using the VESA screws. Start all four screws by hand before tightening with a screwdriver to avoid cross-threading. Ensure the monitor sits flush against the bracket with no gaps.
- Connect and test the arm assembly. Slide or clip the monitor brackets onto the arm mechanism according to your specific arm design. Test the full range of motion including height adjustment, tilt, swivel, and rotation. Tighten the tension knobs to your preferred resistance level for smooth but stable movement.
- Route cables and adjust positioning. Thread your display cables, power cords, and USB cables through the built-in cable management channels. Position each monitor at eye level with the top of the screen at or slightly below your eye height when seated normally. Angle monitors slightly toward your viewing position.
