I tested three monitor arms on my desk. Two stayed.

A good monitor arm lets you float your screen at eye level and reclaim the desk real estate underneath it. After six months with three different arms, the Ergotron LX is the one I would buy again.

I ordered the Ergotron LX Desk Mount in February because my neck was complaining. I had been propping my 27-inch Dell on a stack of O’Reilly programming books for two years. It worked until it didn’t. The screen sat two inches too low, I had no room for a notebook, and the whole tower of books tilted forward one Tuesday morning during a client call. I caught it with my knee. That was the last straw.

What I tested and why

I wanted an arm that could hold a 27-inch monitor without sagging, move up and down with one finger, and clamp to a desk that is only 22 millimeters thick at the edge. I also wanted the option to rotate to portrait mode for reading long documents. I did not want to spend $400. I ended up testing three arms over six months:

• Ergotron LX Desk Mount, around $170
• Fully Jarvis Monitor Arm, around $135
• VIVO Single LCD Monitor Desk Mount, around $35

I kept the Ergotron on my main desk, moved the Jarvis to a secondary standing desk, and loaned the VIVO to a friend who works from a kitchen table. This is what I learned.

The winner: Ergotron LX Desk Mount

The Ergotron LX costs roughly three times what the VIVO costs, and it is worth every dollar if you use your desk every day. The difference is the Constant Force lift technology. You grab the monitor, move it, and it stays exactly where you leave it. No levers, no knobs, no drift. I have adjusted it hundreds of times since February and it has not sagged a single millimeter.

My Dell UltraSharp U2723QE weighs 6.4 kilograms with the stand removed. The LX is rated for up to 11.3 kilograms, so I am well inside the range. The arm arrives in two pieces: the desk clamp and the arm itself. Assembly takes ten minutes if you have a screwdriver. The clamp fits desks from 10 millimeters to 60 millimeters thick, and it includes both a through-desk grommet mount and a C-clamp. I used the C-clamp because I rent my apartment and I do not want to drill holes in furniture that is not mine.

What sold me was the range of motion. The arm extends 64 centimeters from the post, which means I can pull the monitor forward when I am leaning in to inspect a design, then push it back against the wall when I need space to spread out paper invoices. It rotates 360 degrees at the base, 180 degrees at the elbow, and the monitor itself pivots from landscape to portrait in seconds. I use portrait mode at least twice a week for reading long contracts. It feels like cheating.

The real test came in April. I had a client deadline at midnight and my lower back was already tight from sitting too long. I stood up, grabbed the monitor with one hand, pulled it to standing height, and rotated it to portrait so I could read a 40-page contract while pacing next to my desk. The arm moved like it owed me money. No drift. No sag. I finished the review standing up, which I could not have done with any stand-mounted monitor I have owned. My old setup would have required me to hunch over a laptop on a bookshelf.

Cable management is built into the arm. Two plastic channels snap over the lower and upper segments. I routed my DisplayPort cable, one USB-C cable, and my monitor light bar cord through them. The channels are visible. Still, they keep the cables from dangling into my coffee. That matters more than I expected.

The honest downside: the Ergotron LX is not pretty. The aluminum finish is industrial, and the plastic cable covers look like they belong in a cubicle farm. If you want a monitor arm that matches a walnut standing desk, the Jarvis looks better. The LX also costs more than some standing desks themselves. If you are furnishing your first home office, $170 for an arm feels steep. I would still pay it again. My neck pain disappeared within two weeks of installing it.

The runner-up: Fully Jarvis Monitor Arm

Fully sent me the Jarvis arm to compare. I used it on a second desk with a 24-inch LG monitor for three months. It is lighter than the Ergotron, easier to ship, and about $35 cheaper. The gas spring is smooth, though slightly stiffer than the Ergotron’s Constant Force system. You need a little more push to move it, and I noticed a tiny bit of bounce if I bumped the desk hard.

The Jarvis looks better. The white powder-coated finish and rounded joints feel more domestic than industrial. It also has a lower profile clamp that takes up less visual space under the desk. If aesthetics matter to you and your monitor is under 8 kilograms, the Jarvis is a solid choice. I would not use it for a heavy ultrawide. The rated capacity is 9 kilograms, but the spring felt closer to its limit with my Dell than the Ergotron did.

One nice touch: the Jarvis includes a quick-release VESA bracket. You can detach the monitor from the arm in seconds without unscrewing anything. I used this twice when I needed to move the monitor to a conference room. The Ergotron requires a screwdriver to remove the VESA plate, which takes two minutes. Not a dealbreaker, but the quick release is genuinely useful if you move hardware often.

The Jarvis failed me in one way. After about ten weeks, the tension adjustment screw loosened slightly and the arm drifted downward by about a centimeter overnight. I tightened it with the included hex key and it has been fine since, but it shook my confidence. The Ergotron never needed adjustment.

The budget pick: VIVO Single LCD Monitor Desk Mount

The VIVO arm costs roughly the same as a decent lunch in Manhattan. For that money, you get a steel arm with a spring-assisted lift, a C-clamp, and a grommet mount. It holds monitors up to 27 inches and 15.4 pounds. My friend has been using it with a 24-inch Acer since March and it has not fallen off the table yet.

The VIVO is functional, not refined. The spring mechanism is stiff. You need two hands to reposition the monitor: one on the screen, one on the arm to keep it from jumping. The joint at the elbow has a plastic cap that pops off if you knock it. My friend lost his under the fridge during a cleaning spree. It still works without the cap, but it looks unfinished.

Where the VIVO shines is stability for the price. Once you tighten the tension screw to match your monitor weight, it stays put. It does not drift. It does not wobble during typing. The base clamp is wide and grips thin tabletops without flexing. If you have a lightweight monitor and a tight budget, the VIVO gets you 80 percent of the Ergotron experience at 20 percent of the cost.

The tradeoff is ergonomics. The arm does not extend as far from the post as the Ergotron, so you sit closer to the desk edge. That can cramp your forearms if you type for long stretches. The tilt range is also narrower. You can angle the screen up and down, but the range is roughly 45 degrees total compared to the Ergotron’s 75 degrees. If you are tall and your desk is low, you might run out of upward tilt.

How to pick the right monitor arm for your setup

Start with your monitor weight. Check the manufacturer’s website for the weight without the stand. Most 24-inch monitors are under 5 kilograms. Most 27-inch monitors are between 5 and 7 kilograms. Ultrawide 34-inch monitors can hit 9 kilograms or more. Buy an arm rated for at least 2 kilograms above your monitor weight. Arms operate best near the middle of their range, not at the limit.

Next, check your desk thickness. Measure the edge where you plan to clamp. Cheap particleboard desks with hollow cores can crush under clamp pressure. If your desk is less than 18 millimeters thick or has a hollow core, use a grommet mount if there is a cable hole, or buy a reinforcing plate. The Ergotron LX includes a warning about this in the manual that most people ignore until their desk delaminates.

Consider your reach. If you have a deep desk and you want to pull the monitor close for detail work, check the arm extension length. The Ergotron extends 64 centimeters. The VIVO extends about 40 centimeters. The Jarvis is in between. I have a 75-centimeter deep desk and the Ergotron’s reach matters. On a 50-centimeter desk, it is less important.

What I wish I had known before buying

Monitor arms expose the back of your monitor. If you care about cable clutter, buy black cables. Colored cables against a white wall look messier when the monitor floats. I swapped my blue DisplayPort cable for a black one and the difference was immediate.

VESA compatibility is not guaranteed. Almost every monitor made in the last five years has a 75 by 75 millimeter or 100 by 100 millimeter VESA mount pattern, but some ultrathin monitors use a recessed mount that requires standoff spacers. Dell includes these spacers in the box. LG often does not. Measure the depth of the VESA recess before you order an arm, or you will be making a hardware store run on a Saturday.

Also, a monitor arm will make your screen wobble more than a stand does. Any vibration in the desk travels up the arm. If you type on a wooden desk with a mechanical keyboard, you will see a subtle shimmer in the monitor. It does not bother me. A colleague who does video editing found it distracting and added a small felt pad under the clamp to dampen the vibration. It helped.

When a monitor arm is overkill

If you have a laptop-only setup and you never connect an external monitor, skip the arm. Buy a good laptop stand instead. I wrote about my favorite in our guide to the best laptop stand for remote workers. A stand costs less, travels with you, and solves the same neck angle problem.

If your desk is a dining table that you clear every evening, a clamp-mounted arm is annoying to remove and reinstall. Get a riser stand that sits on the table and move it when dinner starts. The best standing desk for freelancers guide covers some dual-purpose options that work well in shared spaces.

And if you already have a monitor with excellent height adjustment built in, like the latest LG Ergo series with its own integrated arm, buying a separate arm is redundant unless you need the extra extension or dual-monitor support.

Who should keep using their monitor stand

Some people will get zero value from a monitor arm. If your desk is shallow, meaning less than 55 centimeters from front to back, the clamp and the extended arm will eat into your usable space. The clamp itself sits roughly 10 centimeters back from the front edge. On a shallow desk, that leaves you typing with your elbows hanging off the front. Stick with the stand that came in the box.

If you share a desk with a partner who uses the same monitor at a different height, an arm actually makes things worse. You will be adjusting it up and down three times a day. A stand with tool-free height adjustment is faster for shared setups. The Ergotron moves easily, but adjusting it precisely to two different people takes finesse. After two weeks of sharing a desk with my visiting brother, I was tempted to bolt the thing in place.

Parents of toddlers should also think twice. A floating monitor on an extended arm is an irresistible climbing frame. My friend with the VIVO arm on his kitchen table has a two-year-old who discovered that the monitor swings. He has since zip-tied the arm in a fixed position, which defeats the purpose. If your workspace doubles as a play zone, a sturdy stand is the safer option.

What I use with my monitor arm

The arm solved my neck angle, but it created a secondary problem. Once the monitor floated, I noticed my keyboard was too low. I added a Drop CTRL mechanical keyboard on a small bamboo riser, which lifted my hands to the right height. I also moved my best ergonomic mouse for freelancers, the Logitech MX Vertical, to the same level. The combination of floating screen and raised peripherals is the ergonomic trifecta I did not know I needed.

I also added a small LED strip behind the monitor for bias lighting. With the monitor pulled away from the wall, the back was visible and the strip clips to the VESA plate. The Ergotron arm does not block the strip. On a stand, the base often covers the lower part of the back panel.

What I learned from six months of daily use

The biggest surprise was how often I move the monitor. I thought I would set it once and forget it. In reality, I pull it forward for focused writing, push it back for video calls where I want more desk visible, rotate it to portrait for contracts, and angle it away from the window during afternoon glare. That is four distinct positions in a typical day. An arm makes those changes effortless. A stand makes them impossible.

The second surprise was social. When colleagues visit my apartment, the floating monitor is the first thing they comment on. It signals that you have thought about your workspace. That sounds shallow, but as a freelancer, your environment is part of your brand. Clients notice.

The third surprise was durability. I expected the gas spring to soften over six months. It has not. The Ergotron still holds position with the same resistance it had on day one. That consistency matters more than any feature list.

A quick checklist before you buy

• Measure your monitor weight without the stand attached.
• Measure your desk edge thickness where the clamp will sit.
• Check for a VESA mount pattern on the back of your monitor.
• Decide if you need portrait rotation. Not every arm supports it.
• Leave 10 centimeters of clearance behind the desk for the clamp.
• Budget for a cable sleeve or ties to match the built-in channels.
• Consider your roommates, pets, and children before choosing a floating arm.

Questions remote workers ask about monitor arms

Do I need a monitor arm if my screen has a stand?

An arm moves the screen to eye level, reclaims desk space, and angles it exactly where you want. A built-in stand works for basic use. The difference is flexibility versus basic support.

Will a monitor arm damage my desk?

Most use a clamp that grips the edge. If your desk is solid wood or composite over 0.75 inches thick, the pressure is spread safely. Hollow-core desks need reinforcement or a grommet mount.

Can one arm hold an ultrawide monitor?

Only if the arm is rated for the weight. Check the monitor weight and the arm capacity before buying. The Ergotron HX is the model to look at for heavy ultrawides, though it costs more.

Are gas spring arms better than mechanical?

Gas spring arms move more smoothly with one hand, but a good mechanical hinge lasts longer with less drift. The Ergotron LX uses a spring system that is closer to mechanical in longevity. The Jarvis uses a traditional gas spring that may need tightening over time.

The honest takeaway

The Ergotron LX Desk Mount is the monitor arm I would buy if I were starting over. It costs more than the competition, but it moves better, lasts longer, and disappears into your workflow in a way that cheaper arms never quite manage. The Jarvis is the better-looking alternative if your monitor is lighter and you do not mind occasional adjustments. The VIVO is the right call if you are on a tight budget and you have a small screen.

I have had the Ergotron since February. I have adjusted it at least twice a day since then. It still feels new. That is the test.

If you are building out a full home office, pair the arm with a good chair and a desk that fits your height. Our guide to the best ergonomic office chair for freelancers covers the options I tested, and the best standing desk for freelancers has budget picks that work with any of these arms.
