Best monitor arms in 2026: picks for OLEDs, ultrawides, and dual screens
A monitor arm frees desk space and puts the screen at eye level. The key spec is weight capacity, and heavy ultrawides need a heavy-duty arm. Four picks.
Our pick: Ergotron LX for most single monitors; Ergotron HX for heavy ultrawides; HUANUO FlowLift Dual for two light monitors on a budget

Cons
- • Heavier monitors lose some vertical range

A monitor arm lifts the screen off the desk, sets it at eye level, and lets you push it back, rotate it to portrait, or swing it aside. Weight capacity is the spec that matters most. These picks use Ergotron's specs and published comparisons of budget arms; we have not tested them.

|---|---|---|---|---|---|
| Ergotron LX | 7 to 25 lb | About 32-inch | 75, 100 | 10 years | ~$205 |

Best overall: Ergotron LX
The LX holds 7 to 25 lb and screens up to about 32 inches, pans 360 degrees and tilts 75 degrees, and carries a 10-year warranty including the tension system. A tall pole and an extension arm are available. Heavier monitors reduce its vertical range.
Best for heavy ultrawides: Ergotron HX
The HX is rated 20 to 42 lb for screens up to 49 inches, with 11.5 inches of lift and VESA patterns up to 200 x 200 mm. Ergotron notes that displays deeper than 6 inches may need its heavy-duty tilt pivot. List price is $460, with dealers selling it around $355.
Best budget: Amazon Basics and HUANUO
Amazon Basics' gas spring arm holds up to 19.8 lb for about $30, and HUANUO's FlowLift Dual mounts two monitors up to 19.8 lb each for about $60. Both are fine for typical 24 to 27-inch monitors; check the weight of 32-inch and OLED models carefully.
Questions we get
How do I know if a monitor arm will hold my monitor?
Check two things: the monitor's weight without its stand, and its VESA mount pattern (usually 75 x 75 or 100 x 100 mm). The weight must fall inside the arm's range, not just under the maximum, because gas springs need a minimum weight to stay put.
Can a monitor arm hold an ultrawide?
Light 34-inch ultrawides often fit standard arms; 39 to 49-inch models usually need a heavy-duty arm like Ergotron's HX, rated 20 to 42 lb for screens up to 49 inches.
Do monitor arms work on any desk?
Most clamp to the desk edge or mount through a grommet hole. Check the clamp's thickness range, and avoid thin glass or particleboard tops without a reinforcing plate.
