Compatibility: To ensure compatibility with the dual monitor mount, your each monitor must meet three conditions at the same time: First, computer screens size range: 13 to 32 inches. Second, screen weight range: 4.4 to 19.8 lbs. Third, the back of the monitor screen must have VESA mounting holes with a pitch of 75x75mm or 100x100mm. We recommend carefully checking that your monitor meets all three conditions before purchasing. If it's still unclear, you can seek assistance from tech support. Customize Your Viewing Angle: The Huanuo dual monitor stand for desk features full motion flexibility with +90°/-35° screen tilt, 180° swivel range, and 360° monitor rotation for landscape or portrait mode. Also, after mounting the monitor, please use the Allen key to adjust the angle and tension of the tilt screw to ensure that the monitor mount is able to support the monitor stably.Easily configure an ergonomic viewing angle that can maximize comfort and productivity.
