Desk clamp for single 34 inch display

The StarTech ARMUNONB1 clamps to desks from .4 to 3.3 inches thick and holds one monitor up to 34 inches or a laptop tray. VESA 75 by 75 and 100 by 100 patterns are supported. A maximum load of 17.7 lbs covers most ultrawide panels and notebooks up to 17.7 lbs. Builders needing wall mounting or dual-screen support should choose a different model.

Full motion articulation range

The arm extends to 22.4 inches and rotates 360 degrees at the base. Tilt adjusts from -85 to +90 degrees while swivel covers -180 to +180 degrees. Display rotation spans 360 degrees for landscape or portrait use. Height travels 13.8 inches along a 12.2 inch pole to a maximum of 22 inches. Users who need longer reach or motorised movement will not find it here.

Steel construction with included tools

The 10.30 lb arm uses a ventilated laptop tray measuring 12.6 by 9.5 inches with rubber pads. All mounting hardware and tools ship in the box for immediate installation. No external power or active cooling is involved so operation stays silent. Buyers wanting integrated cable channels or a lighter aluminium build should look elsewhere.

Questions about this item

Does the arm generate any noise or heat when holding a 34-inch ultrawide all day?

The ARMUNONB1 is a passive mechanical arm with no motors or electronics, so it produces zero noise and no heat during continuous use.

What must I already own to mount this arm on my desk?

You need a desk or tabletop between .4 and 3.3 inches thick for the C-clamp to grip securely; the required hex keys are included in the box.

Will my existing 24-inch monitor with 75x75 VESA holes work on this 34-inch rated arm?

Yes, the arm supports VESA 75x75 and 100x100 patterns and handles displays up to 17.7 lb, so a lighter 24-inch panel mounts without issue.
