Double Monitor Mount: Gas Spring Arms vs Fixed-Tension Arms

By Digital Desk Solutions Editorial Team · Updated October 18, 2026

Last Updated: October 18, 2026

For most desks, the best double monitor mount is a gas-spring arm if you change screen height during the day, and a fixed-tension arm if you set it once and leave it. Among the gas-spring models below, the MSI MAG MT101DG is our top pick: it lists 17 to 32 inch support, 22 lbs per screen, a clamp and grommet base and a quick-release plate. If you would rather pay less and skip the spring, the ErGear dual stand lists 22 lbs per arm and up to 33 inch screens.

The confusing part of buying a double mount is not the size, it is the movement. A gas spring balances the weight of the screen so a light push moves it up or down and it stays where you leave it. A fixed-tension arm holds a position through tightened joints and friction, which is cheaper and simpler but needs a wrench to change height. Neither is better in every case. This guide explains which fits which desk, and picks seven models across both types.

1. MSI MAG MT101DG: Best Overall Gas-Spring Double Mount

Key specs

• Screen size: 17 to 32 inches
• Load: 22 lbs
• Height adjustment: gas spring
• Base: clamp and grommet
• Quick-release plate included
• VESA compatible

Best for: Anyone who raises and lowers screens daily and wants a name-brand mount.

Skip if: your monitors weigh more than 22 lbs each.

MSI is better known for gaming monitors and laptops, so a gas-spring dual arm from the same company is an unusual fit in a desk accessory guide. It makes sense on paper: the listed 22 lbs per screen, 17 to 32 inch range and quick-release plate are good for a home-office or gaming desk.

The quick-release plate is the feature to look at. You attach the plate to the back of each monitor once, then hook the monitor onto the arm and lock it. If you rotate or swap screens, that saves time. For anyone who moves monitors between a desk and a wall, or upgrades every few years, a plate system is easier to live with.

The gas spring takes up less effort for sit-stand users. When you raise the desk, each screen can be pulled up with one hand, and it stays there. Keep in mind that gas springs are tuned to a range; a screen well under the listed weight can float upward. Confirm the tension adjustment on the maker page.

Pros

• Gas-spring movement
• Quick-release plate
• 22 lbs per screen
• Clamp and grommet base

Cons

• Tension range not stated in title
• Not for 34 inch ultrawides

2. suptek Dual Monitor Mount with Base: Best Freestanding Double Mount

Key specs

• Screen size: 17 to 34 inches
• Load: up to 24.25 lbs
• Type: pneumatic (gas spring), freestanding base
• Model code: ML8SPX

Best for: Glass desks, rented furniture or any surface you do not want to clamp.

Skip if: your desk is shallow and a base would crowd the keyboard.

Most double mounts clamp to the back edge. A freestanding base avoids the clamp entirely and weights the arm with the base plate. That makes it the best choice for glass tops, thin tops or desks you do not own.

The listing says up to 24.25 lbs and screens up to 34 inches, the highest weight in the gas-spring set. If your screens are heavy, this is the more comfortable option for load, though freestanding bases are more sensitive to desk bounce than clamped ones.

The base takes up desk space. Allow a footprint equal to the base, and note that the monitors may sit slightly further back than they would on a clamp.

Pros

• No clamp needed
• 24.25 lbs listed capacity
• Gas-spring movement
• Covers 34 inch screens

Cons

• Base takes up desk space
• Slightly more desk bounce

3. GRIFEMA Gas Spring Dual Monitor Arm: Best Mid-Range Gas Spring

Key specs

• Screen size: 13 to 32 inches
• Load: up to 19.8 lbs each
• VESA: 75 and 100 mm
• Motion: 360 degree rotate, swivel, tilt
• Install: easy install

Best for: A pair of 24 to 27 inch monitors where you want a spring but not a premium price.

Skip if: you need to hold 22 lbs or more per screen.

GRIFEMA lists the standard feature set for a mid-range gas-spring arm: 13 to 32 inch screens, 19.8 lbs each, 360 degree rotation, full tilt and swivel. It sits between the budget DUMOS and the premium EVEO in features.

The rotation range lets you turn a screen to portrait for reading or code. Check that your monitor’s stand holes do not collide with the arm, which can happen on curved screens.

A 19.8 lbs rating suits most 24 to 27 inch monitors. For 32 inch 4K screens, check the actual weight first.

Pros

• Gas spring at a mid-range tier
• 360 degree rotation
• Easy install
• Standard VESA

Cons

• 19.8 lbs per screen
• Smaller brand

4. DUMOS Dual Monitor Mount: Best Budget Gas-Spring Double Mount

Key specs

• Screen size: up to 32 inches
• Load: holds 17.6 lbs per screen
• Type: gas spring
• Base: C-clamp or grommet
• Motion: fully adjustable

Best for: Buyers who want gas-spring movement on a tight budget with lighter 24 to 27 inch screens.

Skip if: your monitors are heavy.

The DUMOS has the lowest rating in this group at 17.6 lbs, which still covers many 24 to 27 inch panels. It is the cheapest way here to try a gas-spring arm, and the base choice is the typical clamp or grommet.

The lower cap means that a pair of heavier gaming screens may exceed the limit. If your screens are around 12 to 15 lbs each, you have headroom; if they are closer to 17 lbs, step up.

Smaller brands can have variable finish, so inspect the joints and cable clips on arrival.

Pros

• Gas spring at a low tier
• Clamp or grommet
• Up to 32 inches
• Fully adjustable

Cons

• Lowest weight rating
• Less-known brand

5. EVEO Premium Dual Monitor Mount: Best Premium Gas-Spring Arm

Key specs

• Screen size: 14 to 32 inches
• Type: gas spring
• Motion: full motion
• Weight limit: not listed in the title
• VESA bracket

Best for: Users who want the smoothest premium movement and a polished look on a visible desk.

Skip if: the weight limit not being stated in the title is a deal-breaker until you check the maker page.

EVEO is the premium end of the group. The listing says 14 to 32 inches, gas spring and full motion, but the title does not give a weight limit. Check it before buying, because this is the one piece of information that decides whether your pair will fit.

Premium gas-spring arms normally have a larger spring and a wider tension adjustment than budget ones, which gives a smoother, more controlled feel. That is a general pattern, not a measured claim about this model.

If you work at a fixed desk and move the screens rarely, the premium tier is hard to justify.

Pros

• Gas-spring movement
• Full motion
• Premium tier positioning

Cons

• Weight limit not listed in title
• Highest price tier

6. ErGear Dual Monitor Stand: Best Fixed-Tension Double Mount

Key specs

• Screen size: up to 33 inches
• Load: 22 lbs per arm
• Material: sturdy steel
• VESA: 75×75 and 100×100 mm

Best for: Fixed-height desks where you set the screens once.

Skip if: you want gas-spring motion.

The ErGear is the non-spring option in the list. It lists up to 33 inches and 22 lbs per arm, and it uses a steel build with standard VESA hole patterns. If you set your screens once, a fixed-tension arm is stable and simple.

Compared with gas-spring options, fixed-tension arms require a hex key to change height, which makes them poor for sit-stand desks. On a fixed-height desk they are fine.

Spring type is not named in the listing. Treat this as a conventional mechanical arm unless the maker states otherwise.

Pros

• 22 lbs per arm
• Steel build
• 33 inch capacity
• Simple mechanical design

Cons

• No gas-spring motion
• Spring type not listed

7. HUANUO Stacked Dual Monitor Stand: Best for a Vertical Stack

Key specs

• Screen size: 17 to 32 inches
• Load: up to 19.8 lbs
• Motion: tilt, swivel, rotate
• VESA: 75 and 100 mm
• Layout: stacked, one monitor above the other

Best for: Desks with limited width where one monitor goes on top of the other.

Skip if: you need two screens side by side.

A stacked layout puts the second monitor above the first, which saves width but costs height. It suits narrow desks and ultrawide-plus-secondary setups.

The top screen should be for occasional reference, because tilting your head up to read it for long periods is tiring. Put your main work screen at eye level and the secondary above.

Allow vertical clearance. A 27 inch screen is roughly 16 inches tall, so two stacked take over 32 inches of vertical space before bezels and the arm.

Pros

• Saves desk width
• Tilt, swivel, rotate
• 19.8 lbs per screen
• Standard VESA

Cons

• Needs vertical room
• Top screen strains neck if used often

Also Consider

• WALI Dual Monitor Arm GSMP002N: Not a gas-spring model, but 22 lbs per arm and a clear model code make it a safe fixed-tension alternative.
• VIVO Dual Monitor Stand STAND-V002O: Mechanical articulating arm for 17 to 32 inch screens at 19.8 lbs max.
• Mount-It Dual Monitor Arm: Steel arm for 13 to 32 inch screens at 19.8 lbs each; budget tier.
• HUANUO Dual Monitor Mount 22 lbs: Each arm holds up to 22 lbs and supports screens up to 32 inches; spring type is not listed.

How We Chose

We reviewed dual-arm listings and picked models covering gas-spring and fixed-tension designs, freestanding and clamp bases, and budget through premium tiers. We cross-referenced the stated limits against general ergonomic guidance and the VESA standard.

Mistakes That Make a Double Mount Feel Cheap

• Ignoring the minimum weight and then blaming the arm when a light screen drifts up.
• Clamping onto a hollow desk edge.
• Mounting two different-weight screens on the same type of arm without checking each limit.
• Pulling cables tight so each adjustment tugs on a plug.

Which Mount Fits Which Desk

Whatever you choose, remember that the desk is part of the mount. A clamp bites into the back edge, so a firm 1 to 2 inch thick top is ideal, while a thin or hollow top should use a reinforcement plate. If your desk has a rear lip, a grommet base through a drilled hole is often the cleaner route. Leave at least a few inches between the screens and the wall so the arms can swing without scraping paint.

Finally, think about how you will move the setup later. Quick-release plates, tool-free brackets and standard VESA patterns all make it easier to swap a monitor or move the mount to a new desk. If you move home every couple of years, those small conveniences are worth more than an extra inch of reach.

Frequently Asked Questions

What is the best double monitor mount?

For daily movement, the MSI MAG MT101DG is our top gas-spring pick. For fixed desks, the ErGear dual stand at 22 lbs per arm is a simple alternative.

Is a gas-spring double monitor mount worth it?

Yes if you move your screens often or use a sit-stand desk. If the layout never changes, a fixed-tension arm is cheaper and just as stable.

How much weight can a double monitor mount hold?

It varies by model, from 17.6 lbs per screen on the DUMOS to 24.25 lbs on the suptek. Always check the per-screen rating.

Can I use a double mount on a glass desk?

Use a freestanding base like the suptek, or reinforce the desk. Clamping to glass is risky.

Do I need two matching monitors?

Not strictly, but matching sizes and weights make the arm easier to balance and the screens align better.

What does VESA mean?

VESA is the hole pattern on the back of the monitor, usually 75×75 or 100×100 mm, that lets a mount attach.

Why does my screen drift up on a gas-spring arm?

The spring is stronger than the screen weight. Adjust the tension if the arm allows it, or choose an arm rated for lighter loads.

Which One Should You Buy?

Choose the MSI MAG MT101DG if you want the best-rounded gas-spring arm. Choose the suptek if you cannot clamp. Choose the DUMOS if you are watching the budget. Choose the ErGear if you do not need a spring at all.

Weigh each monitor first and decide how often you will move them. That decides spring or fixed far more than price does.
