The best dual monitor arms hold both screens at eye level, reduce desk clutter, and adjust independently. We tested Ergotron, VIVO, and Amazon Basics dual arms for stability and range of motion.
Our Top Picks
Ergotron LX Dual Stacking Arm
Ergotron
Premium dual monitor arm with independent adjustment for each display and full range of motion.
- ✓Supports two monitors up to 40 lbs each
- ✓Full range of motion on both arms
- ✓Cable management channels
- ✓Desk clamp or grommet mount
Pros
- Each arm adjusts completely independently — critical for side-by-side setups where monitors are at different heights
- Patented CF technology maintains position without drifting after adjustment
- Cable management channels hide cables along each arm
Cons
- Highest price in the dual arm segment
- Assembly takes 30-45 minutes due to tension adjustment requirements
Best dual monitor arm overall. Ergotron's CF technology and independent arm adjustment justify the premium for daily use setups.
VIVO Dual Monitor Arm
VIVO
Budget dual monitor arm with independent VESA mount heads and gas spring support.
- ✓Supports monitors up to 27-inch / 17.6 lbs each
- ✓Gas spring height adjustment
- ✓VESA 75x75 and 100x100 compatible
- ✓Tilt and swivel on each head
Pros
- Half the price of Ergotron with acceptable adjustment range
- Gas spring support holds position without tools after initial setup
Cons
- Less stable under 30-inch+ monitors compared to Ergotron
- Cable management is a clip system, not integrated channels
Best value dual arm. For monitors under 27 inches, the VIVO arm performs close to Ergotron at half the price.
Amazon Basics Dual Monitor Stand
Amazon Basics
Budget dual monitor stand with spring-loaded arms and basic tilt adjustment.
- ✓Spring-loaded arms
- ✓Supports up to 26-inch monitors
- ✓Desk clamp included
Pros
- Lowest price for a functioning dual arm setup
- Spring-loaded arms maintain position adequately for lighter monitors
Cons
- Limited height adjustment range compared to Ergotron
- Less stable for monitors heavier than 12 lbs
Budget dual arm option. For monitors under 26 inches and budgets under $50, acceptable performance.
A single-monitor setup uses one arm. A dual monitor setup needs two arms that share a single desk mount point — either side-by-side at the same level, or one stacked above the other.
The challenge with dual arms is that they need to support significantly more weight than a single arm while maintaining the position stability that makes monitor arms useful. A dual arm that drifts after adjustment, or shakes when you type, is worse than no arm at all.
Our top pick is the Ergotron LX Dual Stacking Arm. The patented CF technology that makes the single Ergotron LX so stable carries over to the dual version, and independent arm adjustment is essential for side-by-side setups where the two monitors are at slightly different optimal heights.
Side-by-Side vs Stacked Configurations
Side-by-side: Both monitors at roughly the same height. The most common dual monitor configuration. Both monitors need independent tilt adjustment so they can angle toward the user from both sides.
Stacked: One monitor above the other. More useful for coders (code above, terminal below) and video editors (timeline below, preview above). Requires a pole-mounted dual arm with vertical position control.
Weight Capacity
Dual arms see double the weight of a single arm. A 27-inch monitor weighs 8-12 lbs. Two 27-inch monitors on a dual arm place 16-24 lbs on the desk clamp. Confirm your desk edge thickness is within the clamp's range (most handle 1.5-3 inch desk edges) before purchasing.
