* The HP Quick Release has been designed to support a maximum of up to 24 lbs (10.9 kg) depending
upon the mounting configuration used. Please note this is a total weight limit for all devices mounted,
i.e. the combined weight of the monitor and a second device such an HP Thin Client cannot exceed 24
pounds. Because mounting surfaces vary widely and the final mounting method and configuration may
vary, mounting fasteners are not supplied (other than the VESA-compliant screws). HP recommends that
you consult with a qualified engineering, architectural or construction professional to determine the
appropriate type and quantity of mounting fasteners required for your application and to ensure that
your mounting solution is properly installed to support applied loads.
