A dual monitor arm clamps to the back of your desk and holds two screens in the air. You get your desk space back, you can set both screens at eye level, and you can swing them out of the way when you need room. The catch is that arms are not one size fits all: a mount that is great for two 24-inch office monitors can sag under a 34-inch ultrawide. Below are seven dual arms that are on sale right now, from a $40 pole mount to a $450 Ergotron, compared on the specs that matter.
Quick answer
Best value: HUANUO DS6 ($69.99), gas spring arms for two 13–32" screens up to 19.8 lb each.

Best premium: Ergotron LX Dual Stacking Arm ($455.95), up to 40" screens and a 10-year warranty.
Cheapest: VIVO STAND-V002 ($39.99), a simple pole mount for 13–30" screens up to 22 lb each.

All seven fit the standard VESA 75×75 and 100×100 mm hole patterns. *B&H's spec sheet lists a 44.1 lb load for the BenQ; check the manual for the exact per-arm limit before you buy. A dash means we could not confirm the warranty from the seller's listing.
1. Ergotron LX Dual Stacking Arm: best premium pick
Ergotron's LX line is one of the best-known monitor arm designs, and this version stacks two displays on top of each other instead of side by side. That is useful on a narrow desk, or if you like a main screen at eye level with a second one above it for chat, a stream or your music. The aluminum and steel build carries a 10-year warranty, which is far longer than anything else here.
- Screens up to 40", up to 20 lb per arm
- Up to 25" of reach and 13" of height adjustment
- 360° swivel and rotation, 75° of tilt
- Clamps to desks 0.4–2.6" thick, or mounts through a grommet hole
- Price: $455.95 at B&H
Pros
- 10-year warranty
- Stacked layout saves desk width
- Long 25" reach
Cons
- Expensive
- 20 lb limit per arm rules out many big ultrawides
- Stacked screens mean more neck movement

2. BenQ Dual Ergo Arm (BDH01): best for tall setups
BenQ makes monitors, so its own dual arm is built around them, but it works with any VESA 75 or 100 screen up to 35". The standout is height: it lifts screens up to 27.6", which helps if you work standing or sit high. BenQ includes a reinforcement plate in the box to spread the clamp's pressure on thin desks.
- Screens up to 35"
- B&H lists a 44.1 lb load capacity
- Height up to 27.6"
- Landscape or portrait
- Reinforcement plate included, 3-year warranty
- Price: $279.99 at B&H (B&H does not ship this one to Canada)
Pros
- Very tall height range
- Reinforcement plate included
- Handles screens up to 35"
Cons
- Pricey for a side-by-side arm
- Per-arm load is not clearly listed

3. Mount-It! MI-12003: best heavy-duty gas spring arm
If you run two heavy screens, like a pair of 32" 4K monitors or a 34" ultrawide next to a vertical screen, you need an arm rated well above their weight. The MI-12003 is rated for 44 lb per arm and uses gas springs, so you can move a screen with one hand and it stays put. It also has a USB-A 3.0 and a USB-C port in the base for a flash drive or a headset.
- Screens 17–35", up to 44 lb per arm
- Gas spring arms, height 5.8–16.4"
- 360° swivel and rotation, tilt −20° to +50°
- Clamp for desks 0.4–3.3" thick or grommet mount
- USB-A 3.0 and USB-C in the base
- Price: $229.99 at B&H
Pros
- High weight limit
- Gas springs make one-hand adjustments easy
- Built-in USB ports
Cons
- Not cheap
- Wide footprint: almost 40" from arm to arm at full stretch

4. MSI MAG MT201D: best for big and ultrawide screens
The MT201D is the only arm here rated for screens up to 45", and it holds 44 lb per arm, which covers most 34" and many 38–45" ultrawides. At $129.99 it costs about half as much as the Mount-It. If you game on an ultrawide and keep a second screen for Discord or a guide, this is the one to look at first.
- Screens 17–45", up to 44 lb per arm
- Height up to 20"
- 360° pivot, 180° swivel, tilt −20° to +50°
- Clamp for desks 0.4–3.1" thick or grommet mount
- 3-year warranty
- Price: $129.99 at B&H
Pros
- Fits the biggest screens in this list
- Strong weight rating for the price
Cons
- Heavy at 18.7 lb itself
- Check that a very wide ultrawide clears your second screen

5. HUANUO DS6: best value
HUANUO is one of the most popular monitor-arm brands on Amazon, and the DS6 is its basic dual model. For $69.99 you get proper gas spring arms instead of a fixed pole, so each screen floats where you put it. It suits the most common setup: two 24" or 27" monitors, or a 27" plus a 32".
- Screens 13–32", up to 19.8 lb per arm
- Gas springs (HUANUO says they are tested for 20,000 cycles)
- 180° swivel, 360° rotation and tilt
- Clamp or grommet mount
- Price: $69.99 at huanuo.com
Pros
- Gas spring arms at a budget price
- Easy to switch screens between landscape and portrait
Cons
- 19.8 lb limit is too low for heavy 32" and ultrawide screens

6. MSI MAG MT101DG: best cheap gas spring arm
On sale at $49.99, the MT101DG is the cheapest gas spring arm here. It has the widest tilt range of the group (−45° to +80°) and handles 22 lb per arm. The big limit: B&H lists it as landscape only, so skip it if you want a vertical screen for code or chat.
- Screens 17–32", up to 22 lb per arm
- Gas spring arms, height up to 16.6", reach up to 18.7"
- 360° pivot, 180° swivel, tilt −45° to +80°
- Clamp for desks 0.4–3" thick or grommet mount
- 3-year warranty
- Price: $49.99 on sale at B&H (regular $69.99)
Pros
- Very cheap for gas springs
- Wide tilt range
Cons
- Landscape only
- Shorter reach than the pricier arms

7. VIVO STAND-V002: cheapest option
The VIVO STAND-V002 has been around for years and has more than 60,000 ratings on Amazon. It is not a floating arm: both screens sit on a steel center pole and you set their height along the pole. That is fine if you set it up once and leave it. At $39.99 it is the easiest way to get two screens off the desk.
- Screens 13–30", up to 22 lb each (32" and 38" versions also sold)
- Tilt +90° to −90°, 180° swivel, 360° rotation
- Height set along the center pole
- C-clamp for desks up to 3.25" thick, or grommet mount
- 3-year warranty
- Price: $39.99 at vivo-us.com
Pros
- Cheapest here
- Simple, sturdy steel build
Cons
- Changing height is slower than with a gas spring arm
- Not good if you move your screens a lot

How to Choose a Dual Monitor Arm
1. Check your monitor's VESA pattern
Look at the back of the monitor for four screw holes in a square. 75×75 mm and 100×100 mm are the standard sizes and every arm here supports both. If your monitor has no holes, you need a VESA adapter, and some curved screens need one too.
2. Weigh the screen without its stand
Use the "weight without stand" number from the monitor's spec sheet. Pick an arm rated a few pounds above it. Gas spring arms also need a minimum weight to work right; a very light screen can drift upward.
| Your screens | What to look for | Good picks from this list |
|---|---|---|
| Two 22–27" office monitors | Up to about 20 lb per arm | HUANUO DS6, MSI MT101DG, VIVO STAND-V002 |
| Two 32" 4K monitors | 20–25 lb or more per arm | Mount-It! MI-12003, MSI MT201D |
| 34–45" ultrawide plus a second screen | 44 lb per arm and a large size range | MSI MT201D, Mount-It! MI-12003 (up to 35") |
| Narrow desk | A stacked arm | Ergotron LX Dual Stacking |
3. Clamp or grommet?
A clamp grips the back edge of your desk, so check your desk's thickness against the arm's clamp range (most here take about 0.4" to 3"). A grommet mount goes through a hole in the desk and is the better choice if your desk sits against a wall with no gap. Glass desks and thin particle board are a bad fit for either; a reinforcement plate spreads the load.
4. Gas spring or pole?
Gas spring arms let you pull a screen closer or push it away with one hand, which is great if you switch between gaming and work or share the desk. A pole mount like the VIVO is cheaper and very stable, but you set the height once and leave it.
5. Measure your desk depth
An arm needs room behind the screens. On a shallow desk, an arm with a longer reach lets you pull the screens forward to a comfortable distance.
Frequently Asked Questions
QIs a dual monitor arm worth it?
Usually yes if you use two screens every day. You free the desk space under the stands, you can set both screens at the same height, and you can angle them toward you. If you never move your screens, a $40 pole mount does most of that.
QCan a dual monitor arm hold an ultrawide?
Only if both the size and weight limits fit. Big ultrawides are often heavier than their size suggests, so check the weight without the stand. The MSI MAG MT201D (17–45", 44 lb per arm) and the Mount-It! MI-12003 (17–35", 44 lb per arm) are the two picks here made for that.
QWhat does VESA 100×100 mean?
It is the distance between the four mounting holes on the back of the monitor, in millimeters. Every arm in this guide supports 75×75 and 100×100.
QWill a monitor arm damage my desk?
A clamp puts a lot of pressure on a small spot. Solid wood and thick desktops are fine. On thin or soft desks use a reinforcement plate (BenQ includes one) and avoid glass tops.
QCan I use one monitor vertically?
Yes with most of these arms, since they rotate 360°. The MSI MAG MT101DG is listed as landscape only, so pick another arm if you want a portrait screen.
