Our quick picks

Ranked by what each one is best at, not by a score we made up. Ratings are what the product showed on Amazon when we last checked — how we rank.

Below: why each one made the list, the numbers worth comparing, and what is wrong with it.

The weight figure on a monitor arm is a range, not a maximum, and misreading that is the most common reason people are disappointed by one. A gas-spring arm is a spring under tension: it is designed to balance a load within a stated window. Hang a monitor heavier than the top of that window and the arm sags, drifting downward however hard you crank the tension screw. Hang one lighter than the bottom of the window and the arm floats upward and will not stay where you put it, which is just as annoying and much less expected.

And there is a trap inside the trap: the weight on your monitor’s spec sheet usually includes its stand. When you mount it on an arm, the stand comes off, which can easily be a third of the total. Find the weight “without stand” in the manual, and match that to the arm’s range. If your screen is very light — a small 24-inch panel — you want an arm whose range starts low, not the heaviest-duty arm you can find.

The second thing to settle before you shop is VESA. The mounting pattern on the back of a monitor is normally 75 by 75 or 100 by 100 millimeters, and both are standard. What is not standard: some monitors, particularly slim consumer models and a number of curved and ultrawide screens, have no VESA holes at all, or need a manufacturer-specific adapter plate. Look at the back of your monitor, or its manual, before ordering anything.

The third is how it attaches to your desk. Almost every arm here offers a clamp and a grommet option, and both have requirements — a flat rear edge within a stated thickness range for the clamp, or a hole for the grommet. A desk with a rear apron, a thick rounded edge, a glass top or a hollow core may not take a clamp at all.

Every arm below is a current Amazon listing rated 4.6 stars or better. We do not publish prices — they change constantly — so use the links to check what each costs now.

Quick picks

• Best overall: Ergotron LX desk mount — the arm that office furniture specifiers have used for years, with a huge height range.
• Best value: VIVO single monitor arm — solid steel and full articulation for a fraction of the premium price.
• Best dual: HUANUO dual monitor mount — two screens up to 32 inches on one clamp.
• Best for ultrawide: HUANUO TitanLift — rated for screens up to 49 inches, which almost no arm is.
• Best premium heavy-duty: Pixio PS2S Titan — the strongest arm here, for the heaviest monitors.
• Best for a laptop plus a monitor: PUTORSEN 2-in-1 mount — a screen and a laptop tray on one arm.

Before you buy: five checks that take two minutes

• VESA pattern. Look at the back of the monitor. Four holes in a square, 75mm or 100mm apart. No holes means you need a manufacturer adapter or a different plan.
• Monitor weight without the stand. From the manual, not the box. Then check it sits comfortably inside the arm’s stated range rather than at either extreme.
• Desk edge. Measure the thickness where the clamp will go, and check there is a flat area at least a couple of inches deep with nothing underneath — a drawer rail or a rear apron will stop a clamp closing.
• Desk construction. A solid wood or thick laminate top is fine. A hollow-core particleboard desk can crush under a clamp, and glass tops can crack — for either, use a wide backing plate, spread the load with a piece of hardwood, or choose a freestanding stand instead.
• Behind the desk. An arm needs clearance to swing and the monitor needs room to move back. If the desk is hard against a wall, you lose much of the benefit.

A safety note

• A monitor arm holds an expensive object over your keyboard and your legs. Tighten everything to the manufacturer’s instructions, then load the monitor and test it firmly by hand before you trust it — push it through its full range and lean on it gently.
• Do not exceed the stated weight capacity, and do not add a second screen to an arm rated for one.
• Re-check the clamp after a week and again after a month. Wooden desks compress slightly and clamps loosen.
• On a standing desk, remember the arm adds both weight and leverage at the rear edge. Stay within the desk’s own load rating, and re-check the clamp after the desk has been raised and lowered a few dozen times.
• If there are children around, be aware that a monitor on an arm is a handle at head height. Route cables so they cannot be pulled, and position the arm so the screen cannot swing into anybody.

Why an arm is worth it at all

Three reasons, in order of how much they matter.

• You can get the height right. Most monitor stands have a small height range or none, and the result is a screen several inches too low, which is why so many people work with their chin down and their neck loaded. The top of the screen should be at or slightly below eye level, at both sitting and standing heights if you have an adjustable desk. An arm is the only practical way to achieve that.
• You can push the screen back. Correct viewing distance is roughly an arm’s length, and a stand with a deep base forces the screen forward. Moving it back reduces eye strain and frees the desk in front of it.
• You get the desk space back. A monitor stand occupies the most useful part of a desk. An arm clamps at the edge and leaves the surface clear, which on a small desk is transformative.

The six monitor arms worth buying

1. Ergotron LX desk mount — best overall

The LX is the arm that turns up in offices specified by people who do this for a living, and it earns that position on two numbers. It fits single screens up to 34 inches, and it raises a monitor through a range of about 17.3 inches — which is an unusually large vertical travel and the reason it works for a tall person at a standing desk and a shorter person seated, on the same arm. It also ships with both a two-piece desk clamp and a grommet mount, so you are not discovering after delivery that your desk needs the other one.

What separates a good arm from a cheap one is how it moves: the LX holds position without drifting, moves with one finger rather than two hands, and does not develop a wobble after a year. At 4.6 stars, with a long warranty and an enormous installed base, it is the arm we would buy and expect to move from desk to desk for a decade.

Where it falls short: it is priced as professional equipment, and there are arms here at a third of the cost that will hold a monitor perfectly well. The weight-range point from the introduction applies particularly to the LX: it is tuned for a reasonably substantial monitor, so a very light 24-inch panel may float rather than stay put — check the stated minimum. Cable management is functional rather than elegant. And there are several LX variants including wall mounts and tall poles, so confirm you are buying the desk mount.

2. VIVO single monitor arm — best value

VIVO has built a reputation on making the boring parts of a desk setup properly at low prices, and this arm is the clearest example. It is solid steel, it fits screens from 13 to 27 inches, and it articulates fully — tilt of 15 degrees each way, swivel, rotation to portrait, and height adjustment. That is the complete set of movements, which plenty of cheap arms omit one or two of.

At 4.7 stars it is the highest-rated single arm in the mainstream price bracket, and for a 24- or 27-inch monitor on a normal desk it does everything the expensive arms do. If you are buying an arm for the first time and are not sure you will like it, buy this one rather than talking yourself out of the idea.

What owners complain about: the height range and the smoothness of movement are a step below the premium arms — it holds position well and it takes two hands to reposition rather than one finger. The 27-inch limit rules out larger and ultrawide screens, and steel construction means it is heavier than an aluminum arm. Check which VIVO model the listing is: the range includes spring-assisted, pneumatic and manual-adjust versions that look similar and behave differently.

3. HUANUO dual monitor mount — best dual

Two monitors on two separate stands is a poor arrangement: the bezels never line up, the heights never match, and the two bases eat the middle of your desk. A dual arm fixes all three at once, and this HUANUO takes two screens up to 32 inches each on a single clamp, with independent adjustment so you can set one straight ahead and angle the other in.

It is built on an aluminum-alloy frame with an upgraded weight capacity over the earlier generation, which matters because dual arms are where cheap ones fail — two monitors put a lot of leverage on one mounting point. At 4.7 stars this is the best-regarded dual mount we found, and getting two screens to the same height with matched bezels is worth the price of admission.

The downside: a dual arm concentrates the weight of two monitors on one clamp, so the desk-construction check from earlier matters far more — a hollow-core desk is a real risk here. Two 32-inch screens side by side need a wide desk and a wide field of view; measure before you assume they fit. Setting up a dual arm takes longer than a single and is easier with a second pair of hands. And check both monitors’ VESA patterns, because a mismatched pair may need two different adapters.

4. HUANUO TitanLift — best for ultrawide

HUANUO appears twice because this is a different class of product, not a variant. Most monitor arms stop at 32 or 34 inches, and a 38- or 49-inch ultrawide is both wider and considerably heavier — a curved 49-inch screen is a lot of mass hanging a long way from its center. The TitanLift is rated for screens up to 49 inches, built from high-strength aluminum, and that rating is the reason to buy it.

If you own an ultrawide you will already know how few arms will take one. At 4.7 stars, with full positional adjustment, this is the one we would fit, and the difference an arm makes on an ultrawide is larger than on a normal monitor because the factory stands on big curved screens are usually enormous and barely adjustable.

What you give up: a 49-inch screen on an arm is a substantial load and a long lever — the desk clamp needs a solid desk, and you should test it thoroughly before trusting it. Very wide screens also swing through a large arc, so check there is room. Some ultrawides have non-standard VESA spacing or require an adapter plate from the monitor manufacturer; verify yours. And with a screen this wide, there is little scope to rotate to portrait, so treat that feature as unavailable.

5. Pixio PS2S Titan — best premium heavy-duty

At 4.9 stars this is the highest-rated arm in this guide, and its distinguishing number is capacity: it holds up to 59.5 pounds, which is far beyond what a normal arm manages and comfortably covers the heaviest consumer monitors including large curved panels and some professional reference displays. Pixio builds it as a heavy-duty premium single arm, and the practical consequence of over-specifying capacity is that even a heavy monitor sits well inside the spring’s comfortable range, so it moves easily and holds position perfectly.

This is the arm to buy if you have a big, heavy screen and you have read the introduction and realized your monitor is at the top of a normal arm’s window. Buying capacity headroom is the cure for sag.

The part that annoys people: it is expensive, and a 59.5-pound rating is wasted on a 15-pound monitor — worse than wasted, because an arm built for a heavy load may not hold a light screen down. Check the minimum, not just the maximum. A heavy-duty arm is also physically larger and heavier, and the clamp requirements are correspondingly stricter. And as the highest-rated product here from a smaller brand, the rating comes from fewer owners than the Ergotron’s — read recent reviews rather than the average alone.

6. PUTORSEN 2-in-1 laptop and monitor mount — best for a laptop plus a screen

A very common desk setup is a laptop and one external monitor, and it is usually arranged badly: the laptop flat on the desk with its screen far too low, the monitor beside it, and the user’s neck doing the work. This mount takes a monitor from 17 to 32 inches on one arm and a laptop up to 18 inches on a tray on the other, so both screens can sit at a sensible height and the desk underneath is clear.

It uses an extra-long three-section spring arm with a removable middle section, which is a thoughtful detail: you get long reach when you need to push a screen back over a deep desk, and you can shorten the arm when you do not, rather than living with a linkage that is always too long for the space. At 4.9 stars it is the best-rated mount of this type we found.

Where it disappoints: a laptop on a tray needs airflow — check your laptop does not draw cooling air from underneath, because a solid tray can block it. Putting the laptop at eye level means the laptop keyboard is unusable, so you need a separate keyboard and mouse; that is the correct setup anyway, but budget for it. Two loads on one clamp means the desk check matters, and a laptop tray extends the load further out than a monitor plate. And 18 inches is the maximum laptop size, so a very large mobile workstation may not fit.

Second tier

Humanscale M2 at 4.4 stars is the arm a lot of design studios and architects’ offices fit, and it works differently from the rest: a mechanical spring rather than a gas cylinder, which means no gas strut to eventually lose pressure and a very light touch to move. It is expensive, it is beautifully made, and it has a narrower weight window than most — check yours fits it.

Ergotron LX wall mount at 4.6 stars is the same arm on a wall plate rather than a desk clamp, for screens up to 34 inches. If your desk cannot take a clamp — glass, hollow, or no suitable edge — and you have a solid wall behind it, this solves the problem entirely, at the cost of being permanent and needing the right fixings for your wall construction.

Amazon Basics height-adjustable monitor riser at 4.6 stars is the non-arm answer: a stackable three-level platform with storage underneath. It does not free desk space and it cannot push the screen back, and it costs very little, needs no VESA holes and works with any desk — including glass ones. For a monitor with no mounting holes, it may be the only option.

How to choose, in the right order

• Check the VESA pattern first. No holes, no arm — unless the manufacturer sells an adapter.
• Find the weight without the stand, and choose an arm whose range brackets it rather than one whose maximum exceeds it.
• Check the desk: edge thickness, a flat clear area for the clamp, and whether the top is solid enough. Hollow or glass means a grommet, a wall mount, or a riser.
• Count screens and measure the desk width. Two 32-inch monitors need more desk and more head-turning than most people expect.
• Then pick the mechanism. Gas spring for easy one-hand movement; mechanical spring for longevity and a light touch; manual adjust for a screen you will set once and leave.
• Check the height range if more than one person uses the desk, or if it is a sit-stand desk.
• Finally, look at cable management — an arm with channels in it is the difference between a tidy desk and a screen with cables dangling behind it.

Frequently asked questions

Will a monitor arm damage my desk?

A clamp on a solid wood or thick laminate desk leaves at most a faint mark under the pad. The risks are hollow-core particleboard desks, which can crush, and glass, which can crack — for either, use the widest backing plate supplied, add a piece of hardwood to spread the load, or use a grommet mount or a wall mount instead. Never overtighten to cure a wobble; the wobble is usually the desk flexing, not the clamp slipping.

My arm sags. Can I fix it?

First, find the tension adjustment — usually an Allen screw on the gas cylinder — and adjust it with the monitor mounted, in small increments, following the manual’s direction for heavier loads. If it is already at maximum and still sags, the monitor is heavier than the arm’s range and no adjustment will fix it. Removing a heavy accessory such as a webcam or a soundbar from the top of the screen sometimes brings it back inside range.

Can I mount a TV on a monitor arm?

Sometimes, and the limits are weight and VESA pattern. Many TVs use 200 by 200 or larger VESA spacing, which a monitor arm plate will not reach without an adapter, and TVs are often heavier than monitor arms are rated for. Check both numbers. A wall mount designed for TVs is usually the right tool.

Do I need a gas spring or is manual fine?

Gas spring if you will move the screen — between sitting and standing, between users, or to show something to someone. Manual adjust is cheaper and perfectly good for a screen you position once and never touch, and it will never lose spring pressure. If you have a sit-stand desk, buy the gas spring.

Will it work with a curved monitor?

Yes, provided the VESA pattern and weight are within range. The thing to check is clearance: a curved screen’s edges come toward you, so it needs slightly more room in front and the arm should let you set the depth accordingly. Large curved panels are also heavy, which is where the heavy-duty arms in this guide earn their place.

How do I get the height right?

Sit normally, look straight ahead, and set the top edge of the screen at or just below that line of sight, roughly an arm’s length away. If you wear varifocals or bifocals, set it lower than that so you are not tipping your head back to use the reading portion. Then, if you have a sit-stand desk, repeat the exercise standing and note whether you need to move the arm each time.

What we would buy

For most desks the Ergotron LX is the arm we would buy, because the height range and the movement quality are what you notice every day for ten years. If you want to try the idea without committing, the VIVO single arm does the job for a fraction of the price. Two screens should be on the HUANUO dual mount rather than on two stands. An ultrawide needs the TitanLift, because almost nothing else is rated for one. A very heavy monitor wants the Pixio’s headroom. And a laptop-plus-monitor desk is transformed by the PUTORSEN 2-in-1.

Before you order any of them: check the VESA holes, find the weight without the stand, and measure your desk edge. Those three checks take two minutes and prevent almost every problem in this category.
