The second monitor arrives on a Tuesday, and the desk that held one screen comfortably now holds none of the space back, which is where a best monitor arm for monitor shoppers starts comparing arms. Lifting both screens off the desktop frees the keyboard, the notebook and the docking station from the clutter. We compared four monitor arms using only what each listing publishes: screen size range, weight capacity, motion range, mounting options, stated standards and warranty.

Pros
- Fits 17 to 49 in flat or 1800R curved screens up to 33 lbs
- Extends 21.14 in and raises up to 20.59 in above the desktop
- Swivels plus 90 to minus 90 degrees, tilts plus 75 to minus 75 degrees, rotates 360 degrees
- 3-Year Warranty stated, the longest term here
Cons
- Bullets state tilt plus 75 to minus 75 degrees while the spec table states a 45-degree maximum tilt; the listing contradicts itself
- C-clamp and grommet both fit desks 0.39 to 1.96 in thick only
- Wooden desk recommended, preferably with no crossbeam underneath
- Heavier build to mount than the lighter picks
Detailed Review
The listing states a heavy-duty single monitor arm for 17 to 49 in screens up to 33 lbs, with VESA 75 and 100 mm, cable management, and C-clamp or grommet mounting. It contradicts itself on tilt: the bullets state plus 75 to minus 75 degrees while the spec table states a 45-degree maximum; the bullets are trusted over the table.
Who it's for: ultrawide and large screens that need a heavy-duty arm. Who should skip it: thick desks over 1.96 in and anyone who wants a light aluminum arm.

Safety and Warranty
What this listing states. This product does not plug in or run on a battery, so safety is not part of its score. 3-Year Warranty. It does not say everything a buyer needs, such as who pays return shipping, so warranty scores 4 of 5. See How We Pick.
Match the mount. Check your screen's VESA pattern, size and weight against the stated range, and check that your desk thickness and edge suit a clamp or grommet mount before you drill or clamp.

How we scored them
The Office Score weighs performance, build, value, safety and warranty. For monitor arms, safety means a stated mounting standard and stability features, so the two arms that state VESA 75/100mm score on that criterion and the two with no stated data score zero. Two of the four state a warranty term, a 10-year term on the WALI and a 5-year term on the ErGear. How we pick explains the weights.
| Product | Office Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| WALI GSMP002N Dual Monitor Arm | 9.6 | 30 | 21 | 21 | 4 | 4 |
| ErGear Dual Monitor Arm | 9.6 | 30 | 21 | 21 | 4 | 3 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
How to choose the best monitor arm for monitor
Match the arm to your screen size and weight
Start with the two numbers every listing leads with. The WALI GSMP002N states 13 to 32 inch screens at 22 lbs per arm, and the ErGear states 13 to 32 inch screens at up to 19.8 lbs, so both suit a pair of standard office monitors. The NB SmooVex states up to 32 inch screens with no capacity stated, and the WALI ultrawide states 17 to 49 inch screens with no capacity stated, so the ultrawide buyer should confirm weight on the listing before ordering. Note the WALI GSMP002N’s spec table says 34 inches maximum and 17 inches minimum, which disagrees with the title’s 13 to 32 inches; trust the title and bullets. Browse the full monitor arms and stands category for more options by size.
Check the mounting hardware against your desk
An arm is only as good as its clamp. The WALI offers a C-clamp and a grommet base, both for desks 0.39 to 2.76 in thick. The ErGear offers a C-clamp for desks 0.39 to 2.56 in thick and a bolt-through grommet for desks 0.39 to 2.95 in thick. Both makers recommend a wooden desk with no crossbeam blocking the underside, which rules out some glass-top and panel desks. Measure the desk thickness before ordering, since a clamp that fits 2.76 in will not fit a thicker edge. Neither REUSED listing states mounting hardware, so check the listing directly.
Compare the motion range you will actually use
Every arm here offers the full motion trio, but the ranges differ. The WALI extends 19.3 in, raises 17.3 in, tilts +70/-45, swivels +90/-90 and rotates 360. The ErGear raises 17.5 in, extends 18.1 in, tilts +80/-50, swivels +/-90 and rotates 360. The ErGear’s tilt range is the widest stated here, useful for standing-desk heights and low seating. The WALI reaches a little farther out at 19.3 in. Rotation to portrait suits coders and document reviewers; if you never rotate, weight the tilt and swivel numbers instead.
| If you need | Look at |
|---|---|
| The longest stated warranty | WALI GSMP002N with a stated 10-year warranty |
| The widest stated tilt range | ErGear with tilt +80/-50 |
| An ultrawide screen | WALI ultrawide, states 17 to 49 inch screens |
| A mechanical spring arm | NB SmooVex, states up to 32 inch screens |
Read the warranty line
Warranty terms separate the confident listings from the quiet ones. The WALI states a 10-year warranty, the longest term here, and the ErGear states 5 years. The two REUSED listings state no warranty term. A stated warranty is the one post-purchase promise you can hold the maker to, so it scores here. If the listing you are reading shows no warranty, assume none until the maker updates the page. Our best monitor arm under 50 guide compares cheaper arms with shorter stated terms.
Frequently Asked Questions
What size monitor does a monitor arm hold?
The WALI GSMP002N and the ErGear both state 13 to 32 inch screens. The NB SmooVex states up to 32 inch screens, and the WALI ultrawide states 17 to 49 inch screens. Check your monitor’s weight against the stated capacity as well as the size.
How do these monitor arms attach to a desk?
The WALI and the ErGear both offer a C-clamp and a grommet or bolt-through mount. The WALI fits desks 0.39 to 2.76 in thick with either option, while the ErGear’s C-clamp fits 0.39 to 2.56 in and its grommet fits 0.39 to 2.95 in. The other two listings state no mounting hardware.
Do these arms tilt, swivel and rotate?
Yes, both full listings state the full motion trio. The WALI tilts +70/-45, swivels +90/-90 and rotates 360, while the ErGear tilts +80/-50, swivels +/-90 and rotates 360. The REUSED listings state no motion details.
Which monitor arms state a warranty?
The WALI GSMP002N states a 10-year warranty and the ErGear states 5 years. The NB SmooVex and the WALI ultrawide state no warranty term.
What does VESA 75/100mm mean?
It is the mounting hole pattern on the back of the monitor: 75x75mm or 100x100mm square. Both the WALI and the ErGear state compatibility with 75x75mm and 100x100mm patterns. Verify your monitor’s VESA pattern before buying, as the listings advise.
Setup Notes
- Measure the desk edge: the WALI fits 0.39 to 2.76 in, the ErGear C-clamp 0.39 to 2.56 in and its grommet 0.39 to 2.95 in.
- Confirm VESA 75x75mm or 100x100mm holes on the monitor back before ordering.
- Route cables through the built-in cable management on the WALI or the cable clips on the ErGear.
- The makers recommend a wooden desk with no crossbeam blocking the underside; check yours first.
- Leave clearance behind the desk: the WALI extends 19.3 in and the ErGear 18.1 in at full reach.
