The only listing that warns the arms stick out the back
A mechanical-spring articulating mount with open-top VESA plates for slide-on fitting — and the only listing on this shelf to warn that the arms project beyond the back of the desk.
VIVO mechanical-spring articulating dual arm
Best for: A desk standing clear of the wall, where a mechanical spring is preferred to a gas cylinder.
There is one sentence on this listing that no other page on this shelf contains in so many words, and it is the reason to read it: “Please Note: The back of the arms will extend past the edge of your desk.” An articulating arm clamped at the back needs room behind the desk for its elbow; a desk pushed flush against a wall takes that space away, and part of the stated range becomes unreachable. VIVO says so before you buy.
The mechanism is a mechanical spring rather than gas, adjusted without tools — the Digitus is the only other mount here to state one. The movement range is the widest on this shelf on one axis — plus 90° to minus 90° of tilt, against plus 90 and minus 45 to 60 elsewhere — with 180° swivel and 360° rotation. The VESA plates are open-topped, so the monitor is screwed to the plate on the desk and then slid onto the arm, which is an easier way to fit a heavy screen alone.
What it does not publish is reach or rise, on a mount whose whole proposition is articulation. The screen window is 17 to 32 in at 4.4 to 19.8 lb each, with no combined figure, and the two fixings have different limits — a C-clamp to 3.1 in and a grommet to 1.9 in — which is worth checking against a thick top before assuming either will do. At about $50 it costs the same as the MOUNTUP, which does publish reach and rise.

Because a desk pushed against a wall does not have the room. An articulating arm clamped at the back needs clearance behind the clamp for the elbow to fold into, and if the desk is flush to the wall the arms cannot reach their full range. VIVO is the listing on this shelf that says so outright: "Please Note: The back of the arms will extend past the edge of your desk." The Acer asks you to check your desk depth; the others say nothing.
A gas spring tends to be smoother; a mechanical spring is a steel spring with no gas to leak. On this shelf two listings state a gas spring, the Acer and the Mount-It! independent arms, and two a mechanical spring, this VIVO and the Digitus; the rest do not say. Neither type publishes a lifespan here beyond the Acer's and MOUNTUP's 20,000-cycle claims.
With the C-clamp, tops up to 3.1 in; with the bolt-through grommet, only up to 1.9 in. VIVO gives no minimum thickness. For a top over 3.1 in, the Amazon Basics clamps up to 4.25 in.
A steel desk-clamp mount for two 13 to 32 in screens at up to 8 kg (17.6 lb) each, with a 5-year guarantee — about €21 in Germany but about $58 on Amazon.com.
Best for: Two light-to-medium screens on a standard desk, for a buyer who values a long guarantee — ideally bought at the European price.
22 lb per arm — level with the Digitus, the highest on this shelf — at the lowest price here, on a listing that spends most of its bullets on what can go wrong.
Best for: Two heavy screens on a thick desk, for someone willing to set the tension properly before trusting it.
The longest reach and the greatest height range of the clamp mounts on this shelf — 21.25 in and 18.1 in — on a gas-spring arm stated to have passed 20,000 durability cycles.
Best for: A deep desk and a tall person, where reach and rise are the binding constraints.
The one holder in this hub that clamps to the side of a monitor instead of a desk, with a silicone-coated cradle and a stated panel range of 0.2 to 0.7 in.
Best for: A desk with no spare edge and no spare surface, where the monitor is the only thing left to hang from.
A freestanding aluminum and TPU stand that publishes both its height and its base width — 8.85 in on 3.7 in square — and asks, in its own listing, for a desk that is flat and dust free.
Best for: A desk where a stand has to be moved around rather than fixed to one edge, and where the surface is flat.
A vented metal riser with three heights and a 20 kg (44 lb) rating — the same figures as the WALI riser in this hub, at about five times the WALI's US price.
Best for: A single monitor that needs one of three set heights — at its European price; in the US, the WALI does the same for a fifth.
