VIVO Dual Monitor Arm — The Budget Way to Get Two Screens Off Your Desk
Dual arms are where budget options make the most sense. Instead of paying premium prices for two arms, a VIVO dual mount gives you two adjustable screens on one clamp at a fraction of the cost. VIVO sells many variants, and current retail listings range from roughly $35 to $100 depending on the spring type and screen size.
The trade-offs are in the details. Reviews of budget gas-spring and mechanical dual arms commonly mention clamps that struggle on thick desks and some wobble when the arm is fully extended. None of that makes them a bad purchase for a standard monitor you rarely move, but it is why the capacity range, clamp thickness and arm reach on the listing deserve a careful read.
Ergotron LX — The Premium Single-Monitor Reference
The Ergotron LX is the arm most other single-monitor arms are measured against. It supports monitors from 7 to 25 lb and screens up to 34″, with a 13″ lift range, 75° of tilt and full 360° pan and rotation.
What the extra money buys is mostly motion quality and longevity. Ergotron states that its arms pass a 10,000-cycle motion test and uses constant-force technology, so the screen stays where you leave it with very little effort. One detail to check on curved or deep monitors: Ergotron notes that a monitor depth over 2.5″ can reduce the arm’s capacity.
Ergotron LX Dual Stacking Arm — Two Premium Arms on One Pole
The LX Dual Stacking Arm puts two LX-style arms on a single pole, one above the other. Each screen is rated for 7–20 lb, with a combined limit of 40 lb, and the standard version is designed for screens up to 24″.
Check the exact variant on the listing before you buy: Ergotron also sells a tall-pole version rated for larger screens, and the dimensions and capacity are not identical. Compared with a budget dual arm, you pay more for smoother movement on both screens and a longer warranty, but you give up the very wide screen support some budget arms advertise.
Ergotron HX — Heavy-Duty Arm for Large and Ultrawide Monitors
The HX is built for monitors that overwhelm a standard arm. It is rated from 20 to 42 lb (9.1–19.1 kg) and supports screens up to 49″, with a lift range of 11.5″.
Two details matter. First, the arm’s minimum is 20 lb, so it is meant for heavy displays, not light monitors. Second, for very large curved models such as the 49″ Samsung Odyssey G9, Ergotron recommends adding its HX Heavy-Duty Tilt Pivot accessory. Ergotron also notes that a display depth over 6″ can reduce the arm’s capacity.
Which Monitor Arm Matches Your Monitor?
Start with the weight of your monitor (without the stand, from the manufacturer’s spec sheet), then match it to the arm’s rated range.
Two standard monitors, tight budget
A budget dual arm such as the VIVO covers most 24″–27″ monitors, as long as each screen is within the listing’s weight range.

Before You Buy: A 6-Point Checklist
- Monitor weight without stand: check it against the arm’s minimum and maximum.
- VESA pattern: most arms support 75 x 75 and 100 x 100 mm. Larger screens may need 200 x 100 or 400 x 400 mm.
- Monitor depth: thick or curved monitors can reduce an arm’s capacity.
- Desk thickness: clamps have a minimum and maximum, and thick desks can be a problem for some budget clamps.
- Mount type: clamp or grommet, and whether your desk has a rear lip or hole.
- Reach and height: check how far the arm extends and how high it lifts for your seating position.

Frequently Asked Questions About Monitor Arm Prices
How much should I spend on a monitor arm?
Match the arm to your monitor’s weight first. For standard monitors, budget dual arms start around $35 and run to roughly $100 depending on the model. Premium Ergotron arms usually cost two to three times as much or more, and the heavy-duty HX costs more than the LX.
Is an Ergotron monitor arm worth the extra money?
It can be if you adjust your screen often, use a standing desk, or want an arm to last for years. If you set the monitor once and leave it, a budget arm with the right weight range may be enough.
Do I need a heavy-duty arm for an ultrawide monitor?
It depends on the weight, not the width. Check your monitor’s weight without its stand. If it is within a standard arm’s rated range, you do not need heavy-duty. If it is above about 25 lb, look at the Ergotron HX.
Can a monitor arm hold a curved monitor?
Often yes, but depth matters. Ergotron notes that a monitor deeper than 2.5″ can reduce the LX’s capacity, and a depth over 6″ can reduce the HX’s. Check the depth in your monitor’s specifications.
What is the difference between a gas spring and a mechanical arm?
Gas spring arms adjust smoothly without tools. Mechanical arms generally need manual tightening to reposition. Gas spring arms are usually the better choice if you change your monitor height often.
Does a dual monitor arm cost less than two single arms?
Often, since you pay for one pole and one clamp. Check the combined weight limit and whether your desk can support both screens at the clamp point.
Our Final Take
The right monitor arm is the one that matches your monitor’s weight and how you use your desk, not the most expensive one.
- VIVO Dual Monitor Arm: the budget route to two screens for standard monitors.
- Ergotron LX: the premium single-monitor arm for 7–25 lb screens.
- Ergotron LX Dual Stacking: premium motion for two standard monitors.

Before buying, confirm the current price, weight range, VESA pattern, desk thickness limits and warranty on the exact listing.
