The onn Full Motion Dual Monitor Desk Mount is a clamp-and-grommet desk arm that holds two 13 to 32 inch screens, each up to about 19.8 lb. Each arm tilts, swivels 360 degrees and rotates to portrait, and cable clips run cords along the arms. It is a budget alternative to name-brand dual arms from Vivo and Amazon Basics: it covers the same core motion and VESA mounting, but the gas or spring tension is fixed rather than adjustable, so heavy screens can sag and light ones can feel stiff. It suits home-office and dorm setups where two screens need to float above the desk without a big spend.

Owners rate it well overall and mostly praise the motion range and the desk space it frees. Complaints center on arms that sag under heavier monitors and on fiddly assembly.
Set up a flexible two-screen workstation with the onn Full Motion Dual Monitor Desk Mount, built to hold two displays from 13 in to 32 in. Each arm moves independently so you can tilt, swivel, and rotate each screen to fine-tune your viewing angle and switch between landscape and portrait orientation as your work calls for it. Integrated cable management helps route cords more neatly for a tidier desk.
