Which single monitor arm suits your working day?
A single monitor arm is useful when the supplied stand occupies the space you need for a keyboard, notebook or second task. It can also let you move the screen between a normal typing position and a closer reading position. The right choice depends on how often you will move it and whether the furniture can accept its attachment.
Do a layout trial with the original stand first. Sit at your usual working height, place the keyboard and mouse where your shoulders stay relaxed, and mark the screen face position. An arm should be able to reach that position without forcing the display towards your face. If you only need a little extra height and the stand already adjusts sufficiently, keeping it may be the better result.
Invision MX200: when the screen moves regularly
The MX200 is the starting option here for a compatible everyday display. Its gas-assisted movement is useful when you change the position during the day, rather than wanting a fixed-height pole. Its 2 kg minimum matters just as much as the 9 kg maximum: a very light portable screen may not balance.
An everyday adjustable screen
Invision MX200
The gas-assisted arm suits a single compatible screen you move between tasks. It frees the desk from a broad stand and gives you a choice of edge clamp or through-desk fixing.
A centred clamp can leave the elbow in the way of the wall. Check whether the clamp can sit to one side while keeping the screen centred. Match the fitting diagram to the base supplied.
- 19–32″
- 2–9 kg
- VESA 75 × 75 or 100 × 100 mm
Give the elbow a route to fold. Moving the clamp to one side can help keep a screen centred while the joints fold along the rear edge, but you must check the actual reach and swivel limits. A maximum reach describes one extreme, not the distance at which every combination of height and angle is available.
VIVO STAND-V001: when you set the height once
A mechanical arm avoids balancing a gas spring. You can still adjust the joints, but changing the main height means supporting the screen while loosening and securing the collar. That suits a single-user desk where the viewing height rarely changes. It is less convenient for a desk shared by people who need different heights several times a day.
Set the height and leave it
VIVO STAND-V001
A mechanical pole arm gives one screen reach and swivel without a gas spring to balance. It suits a working position you adjust occasionally rather than several times a day.
Support the screen before releasing the height collar. The website and manual differ slightly on maximum clamp thickness; confirm your supplied instructions near the limit. Curved screens need model-specific confirmation.
- 13–32″ standard; up to 38″ ultrawide
- Up to 22 lb (about 10 kg)
- VESA 75 × 75 or 100 × 100 mm
Duronic DM12X1: when there is little space behind the screen
The short upright is a different solution from a folding arm. It avoids a long rear elbow, which can help on a desk close to a wall. It also offers less freedom to move the screen towards or away from you. Check the required head position and plug clearance before deciding that the simpler shape solves the layout.
The short upright
Duronic DM12X1
A short upright puts the VESA plate close to the base and does away with a long swinging elbow. Choose it for one screen that normally stays in the same place.
The head tilts and its height can be set by hand while supporting the screen. Check the height you need and ask Duronic to confirm clamp fit on your measured edge. Duronic calls for a solid wood top and rules out thin MDF.
- 17–30″
- Up to 8 kg
- VESA 75 × 75 or 100 × 100 mm
Record the screen details before comparing prices
Find the full model code on the monitor label and open its manufacturer specifications. Record the weight without the stand, including any VESA adapter or accessory carried by the arm. Then check the mounting-hole pattern and plate access using our VESA fit guide. A recessed mounting area, unusual screw length or external adapter can change the result even when the hole spacing matches.
For example, a 27-inch screen weighing 6 kg without its stand is inside the MX200’s published size and load ranges. That is only the first check. A 100 mm hole pattern, suitable screws, enough space for the mounting plate and an approved desktop are still required. Conversely, a 10 kg screen is outside that arm’s 9 kg limit even if it is only 27 inches across.
Invision MX450: when the screen exceeds the smaller arm’s limits
The current MX450 has a wider published weight and size envelope. It is worth considering for a compatible screen above 9 kg, but its longer reach and larger moving assembly need space. Deep curvature can increase the demand on the tilt head; obtain confirmation for the exact monitor rather than relying on its diagonal size.
A larger or heavier screen
Invision MX450
The MX450 handles a wider size and weight range. It is the shortlist option for a compatible display above the MX200’s 9 kg limit, provided the desktop and tilt head can take it.
The longer arm needs room to move. If your screen is deeply curved, ask Invision to confirm the exact model with the tilt head. Check for the 24–40 inch, 2–15 kg revision.
- 24–40″
- 2–15 kg
- VESA 75 × 75 or 100 × 100 mm
If you are choosing for a wide curved display, use the more specific ultrawide arm comparison. It explains why a high kilogram rating alone does not establish compatibility.
Check the desk at the planned clamp position
Measure the thickness where the upper and lower clamp surfaces will actually bear. A decorative lip, bevel or metal rail can prevent full contact even when the quoted thickness is within range. Use our clamp-clearance measurements to record the flat landing depth and room to turn the handle.
A desktop’s overall load rating does not establish that it can accept a concentrated clamp load. Confirm the top’s material and the furniture maker’s mounting instructions. The Invision manuals also call for sufficient support for the complete installation; the local fixing still needs approval. A plate distributes contact over a wider area but does not turn an unapproved hollow top into an approved one.
If an edge fixing is blocked, compare clamp and through-desk mounting. If neither is permitted, a freestanding VESA stand may work, provided its base fits the available surface and the whole assembly stays stable.
Allow for cables, movement and the next screen
Lay out the full movement path before tightening cable clips. Check the screen in its nearest, furthest and rotated positions, leaving relaxed cable loops at moving joints. A short HDMI or power lead can pull against a connector even though the arm itself moves freely. On a height-adjustable desk, check the cable route at both desk heights as well.
Follow the supplied fitting order and support the screen during adjustments. If you are likely to add a second display, first decide whether you need a shared base or a second independent clamp. Our two singles versus one dual arm guide covers the practical difference without assuming that a future dual setup will fit the same space.
If you change screen height often, compare tool-locked and gas-assisted lift. If you use a laptop as the second display, check a shared mount with a laptop tray.
Common questions
Will any monitor fit a single arm?
No. Match the exact screen’s bare weight, mounting pattern, plate recess and fasteners, then check any size or curvature restrictions. The desktop and fixing must also be suitable.
Is a gas-assisted arm better than a mechanical pole?
It is usually more convenient for frequent height changes within its supported load range. A mechanical pole can suit a screen that stays at one height and does not require a spring to balance.
Can I fit an arm to a desk against a wall?
Sometimes. Check the clamp, elbow, screen casing and rear plugs at the position you will use. A short upright may help, but still needs a suitable attachment and cable clearance.
Why does my monitor rise after I let go?
Check the arm’s minimum load and follow its tension instructions with the compatible screen installed. A monitor below the minimum weight may rise even at the lowest tension setting.
Should I buy an arm for a heavier future screen?
Choose for the screen you will actually mount. A heavier-duty spring can have a minimum load that your current screen does not meet. Recheck both monitors before assuming one arm suits both.
