The short answer
Buy the arm if your desk will take one. A clamped arm holds the screen out over the rear edge of the desk, which hands you back the several inches of depth a factory stand or a stand base consumes, and it repositions in seconds — which on a sit-stand desk means the screen can be at the right height standing and seated. The Ergotron LX publishes 26 lb of capacity, about 13 inches of lift and a ten-year warranty. Buy a freestanding stand if your desk has no clear clamp edge, is under about 0.6 inches thick, is glass, or is not yours to clamp to. The VIVO STAND-V001H takes a 22 lb screen on an 18-inch pole and asks nothing of the desk beyond a 15.5 by 11 inch footprint.
Both products hold a screen off the desktop. Where they differ is where the load goes.
A monitor arm clamps (or bolts through a grommet) to the rear edge of the desk, so the weight transfers into the desktop itself near the back — the stiffest part of it. The screen then cantilevers out over the desk on a jointed arm. Nothing sits on your working surface.
A monitor stand sits on the desktop on a base, holds a pole, and the screen attaches to the pole. It needs no clamp edge, no drilling and no permission. It occupies the desk.
That is the whole structural distinction, and everything below follows from it.
The usual argument for an arm is adjustability. The better argument is depth.
A 27-inch monitor on its factory stand needs the base depth plus a comfortable viewing distance in front of it, and a comfortable viewing distance for a screen that size is roughly an arm's length. Add a keyboard and your forearms in front of that, and a 27.5-inch desktop is already fully committed with one screen on it. The arm removes the base entirely and pushes the panel back over the rear edge, which is often three to five inches of working depth recovered.
Where this gets decisive
A stand recovers some of this — the pole base is usually smaller than a wide factory stand — but the base is still on the desk. The VIVO single stand's base is 15.5 by 11 inches, which is real desktop.
This is the part that decides the question for most people, and it almost never appears in an arm-versus-stand article.
A clamped arm needs a clear, flat, solid rear edge of workable thickness. Ergotron is explicit that the LX is the wrong product if your desktop is under about 0.6 inches thick or has no clear clamp edge. Five things take that edge away:
If any of those is true, the decision is made and it is not a compromise — it is the correct product for your desk. That is exactly why the stand ranking exists alongside the arm ranking.
On a fixed desk, you set the screen height once and forget it. On a sit-stand desk your eye line relative to the desktop changes every time you switch position — you are taller standing than your seated eye height plus the desk travel, and the correct screen height relative to the desk is genuinely different in the two positions.
An arm lets you fix that in a second. A stand lets you fix it if you are willing to loosen a pole clamp, which in practice means you set a compromise height and live with it.
There is a second sit-stand-specific point about load. On a two-leg frame the legs sit inboard of the ends of the top, leaving a span in the middle with nothing under it. A screen on a stand puts its weight into exactly that span; an arm transfers it to the stiff rear edge near a leg. The effect is perceived movement rather than failure, and how much the arm actually helps, and the two cases where it does not is worth reading before assuming it solves everything. The free fixes matter at least as much.
| Ergotron LX arm | VIVO STAND-V001H | |
|---|---|---|
| Mounting | Clamp or grommet to the rear desk edge | Freestanding on a 15.5" x 11" base |
| Desk requirements | Clear flat edge, about 0.6" thick or more | None |
| Capacity | 26 lb | 22 lb |
| Height travel | About 13" of lift | Adjustable along an 18" pole |
| Desktop consumed | None | The base footprint |
| Articulation | Full arm reach, tilt, pan, rotate | 15° tilt either way, 90° swivel, 360° rotation |
| Warranty | 10 years | 3 years |
| Repositioning | One hand, in seconds | Loosen the pole clamp |
The capacity figures are closer than people expect — 26 lb against 22 lb — so this is rarely the deciding spec for a single screen. The warranty gap is wide and real. The deciding row is "desk requirements".
There is a case neither product serves well: your screen is simply too low, you never want to move it, and you do not need articulation at all. For that, a fixed riser is the right answer and costs a fraction of either.
The VIVO 24-inch tabletop riser takes 44 lb — more than either product above — on a fixed shelf 23.8 by 10.3 by 4.6 inches, with no VESA mount, because the monitor sits on its own factory stand on top. No adjustment at all, which is both the limitation and the point. It is also the cheapest way to get a screen off a desk, which makes it the sensible pick inside a sub-$200 setup.
What a riser cannot do is help on a sit-stand desk, for the reason this page has been circling: it fixes the screen relative to the desktop, and the correct height relative to the desktop changes when you stand. The full ranking of stands and risers covers all four, including the extra-tall pole for a high eye line.
Neither product on this page has been used by anyone here. Every figure above is Ergotron's or VIVO's own published specification, cited below, and the method behind the scores is published in full.
In detail
26 lb, 13 inches of lift, ten years, and it hands back the depth a stand base occupies.
Skip it if your desktop is under about 0.6" thick or has no clear clamp edge — you will be fighting the mount, not the arm.

A 22 lb freestanding pole on a 15.5" x 11" base — no clamp edge, no drilling, no desk requirements.
Skip it if your desk has a usable clamp edge and a top over about 0.6" thick — a clamped arm frees the desk surface entirely and anchors the load to the stiff edge instead of the span.

How we picked
Each product here is chosen the way a well-informed buyer would choose it: read the maker's spec sheet, manual and warranty terms; record the figures that decide whether a desk fits a body and stays still at height; confirm replacement parts are actually sold; then score it against a published rubric. The UPLIFT V2 adds something extra — it is owner-tested long-term, the desk Mike bought and works at daily.
Scores are weighted editorial judgments from that documented research, shown as a criterion-by-criterion breakdown so you can see which strengths earned each ranking. Nobody pays for placement. The rubric and the weights are on the How We Pick page.
Questions
As a product, yes — it consumes no desktop, repositions in one second and transfers the load to the stiff rear edge of the desk. As a purchase it depends on your desk: an arm needs a clear, flat rear edge at least about 0.6 inches thick, and a stand needs nothing at all.
No. Ergotron states the LX is the wrong product if the desktop is under about 0.6 inches thick or has no clear clamp edge. A cable tray across the back, a desk flush to a wall, a thin laminated top, a glass surface or a desk you do not own all rule a clamped arm out.
That is its main advantage. It removes the factory stand base and pushes the panel back over the rear edge, typically recovering three to five inches of working depth. On a desk shallower than 30 inches, and especially with two screens, that is the difference between a comfortable viewing distance and leaning back.
They reduce perceived movement rather than causing it. A screen on a stand loads the unsupported span between a two-leg frame's legs; an arm transfers that weight to the stiff rear edge near a leg. The bigger factor is how close to full extension you run the desk, since every telescoping frame is least rigid at the top of its range.
Buy a fixed riser rather than either. The VIVO 24-inch tabletop riser takes 44 lb on a shelf 4.6 inches tall with no VESA mount needed, for far less than an arm or a stand. It cannot help on a sit-stand desk, though, because it fixes the screen relative to a desktop whose height keeps changing.
