- Compatibility: To ensure compatibility with the dual monitor stand, your each monitor must meet three conditions at the same time: First, computer screens size range: 13 to 32 inches. Second, screen weight range: 17.6 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.
