Best monitor arm for a 27-inch monitor
For most 27-inch monitors, the HUANUO arm is the best value: it covers 13–32 inches up to 17.6 lb with clamp and grommet mounts. The Amazon Basics arm is fine for lighter screens; the Ergotron LX is the buy-for-life pick.
Almost every arm fits a 27-inch screen. What decides it is weight: HUANUO takes up to 17.6 lb, Amazon Basics 4.4–15.4 lb, and Ergotron LX 7–25 lb. Weigh your monitor without its stand and check for VESA 75 or 100 mm holes.

Check price on Amazon How to choose an arm for a 27-inch monitor
Weigh the monitor without its stand, then pick the arm whose range puts your monitor in the middle, not at the edge.
Weight range
Aim for your monitor to sit mid-range so the spring holds its position.
VESA
Check for 75×75 or 100×100 mm holes on the back.
Mount
Clamp needs a solid desk edge; grommet needs a hole.
Height
OSHA recommends the top of the screen at or slightly below eye level.
