Dual Ultrawide Pneumatic Mount

This VIVO desk mount holds two ultrawide monitors up to 57 inches or TVs up to 55 inches each. It supports VESA patterns from 75x75 mm to 200x200 mm. Each arm carries 4.4 to 59.4 lbs for flat screens or 4.4 to 48.4 lbs for curved screens. The steel and plastic construction targets users who need side-by-side large displays on a single stand.

Top Clamp Install With Reinforcement

The C-clamp and optional grommet bolts tighten from above the desk on surfaces 0.4 to 1.97 inches thick. A reinforcement plate adds extra security for thinner tops. All hardware and instructions are included for assembly. Installers must verify their desk thickness falls in range and that each screen's VESA pattern matches one of the supported layouts before mounting.

Spring Counterbalance Limits

The pneumatic spring assists height adjustment across 12 inches with extra travel along the extension pole. Articulation covers +45° to -45° tilt, 180° swivel, and 360° rotation. Screens lighter than 4.4 lbs or heavier than the stated maximum per arm will not stay in position. The fixed pole height and arm reach define the maximum screen centre height and lateral spacing.

Questions about this item

How do I verify the pneumatic arms are counterbalancing my 57-inch ultrawides correctly after mounting?

Each arm should hold position without drifting when you release it, and the height adjustment should feel smooth through the full 12-inch range with monitors between 4.4 and 48.4 lbs (curved) or 59.4 lbs (flat)

What hardware comes in the box and what must I source separately for a 1.5-inch thick desk?

The package includes the dual pneumatic arms, extension pole, C-clamp, grommet bolts, reinforcement plate, VESA brackets for 75x75 through 200x200 patterns, cable covers and all assembly hardware — no extra parts are needed for desks up to 1.97 inches thick

Which VESA pattern should I choose for my 200x200 ultrawide versus a 100x100 secondary monitor?

The supplied brackets support 75x75, 100x100, 100x200, 200x100 and 200x200 mm patterns, so both monitors attach directly using the appropriate hole set on each bracket
