Triple 15-28" monitor mount for compact desks

The Amer Mounts HYDRA3 holds three flat or curved screens from 15 to 28 inches, plus most 29-inch displays, on a single white clamp base. Spring-loaded articulating arms give each monitor independent tilt, swivel, rotation and height adjustment. Standard VESA 75×75 and 100×100 patterns cover the vast majority of current panels. Internal cable channels keep routing tidy.

Suits multi-screen productivity setups.

Ideal for traders, coders or editors who want three aligned panels at matched heights without separate stands. The clamp fits typical desk thicknesses and frees surface space. Builders needing support for screens larger than 29 inches or heavier than the arm's spring range should look at floor-standing or reinforced alternatives.

Clamp-on install with spring tension tuning

The built-in clamp secures to the desk edge in minutes using hand-tightened screws; no drilling required. VESA plates attach to monitors first, then slide onto the arms. The most common issue is balancing the spring tension — too light and the monitor drifts, too stiff and it resists movement. Adjust the tension bolt per screen until each stays put at any angle.

Questions about this item

Do I need a desk thick enough for the built-in clamp on the HYDRA3?

The mount attaches with its built-in clamp, so your desk must be thick enough to accept that clamp and sturdy enough to hold three monitors plus the arm assembly.

Will my current 100×100 VESA monitors work alongside the HYDRA3’s 75×75 and 100×100 interfaces?

Yes, each arm uses standard VESA 75×75 or 100×100 patterns, so existing monitors with either mounting hole spacing will attach directly.

How can I verify the HYDRA3 is moving through its full range after installation?

Check that each screen achieves 360° rotation, ±90° swivel, -90° to +85° tilt at the hinge, ±45° height adjustment on the arm, and that the extension arms add 15" of reach for lateral articulation.
