This desk monitor mount fits most monitors from 10″-27″, these monitors have a 75 x 75 mm or 100 x 100 mm VESA hole pattern. The arm provides +/-90° rotation, +/-45° tilt, 360° rotation, and supports landscape or portrait orientation, all of which can raise your monitor to a better viewing angle. The dual monitor arms are fixed on the desktop instead of the original base through a bracket, effectively saving desktop space. The wiring design makes your desktop more tidy. We also provide you with a full set of accessories and manuals, so don’t worry about not installing them.
