Frequently Asked Questions

Will this hold two 32-inch monitors?

Yes, if each one weighs 26.5 lbs or less and has 75x75 mm or 100x100 mm VESA holes. The stand supports 13 to 34 inch screens and has a 33-inch arm span, so two 32-inch panels fit side by side.

Can I mount a monitor vertically in portrait mode?

Yes. Each arm offers 360-degree rotation, so you can turn either screen to portrait for documents, code, or long web pages, plus +/-45 degrees of tilt and +/-90 degrees of swivel.

Does it clamp to the desk or go through a hole?

Both options are included. The C-clamp fits desk edges 0.39 to 3.15 inches thick, and the grommet mount fits 0.39 to 2.17 inches through an existing hole.

Will it work on my glass or particle-board desk?

ErGear only recommends wooden desks for this mount. Check that your desk is wood, within the thickness range, and free of beams or panels underneath that would block the clamp.

Is it hard to assemble?

ErGear ships labeled hardware and a step-by-step manual. Confirm your desk thickness, material, and each monitor's VESA pattern first, since those checks cause most of the setup trouble.
