Why pick HUANUO Single Monitor Arm?
A monitor arm puts the top of the screen at or slightly below eye level and frees desk space. HUANUO’s arm covers the most common monitor sizes and weights with smooth gas-spring adjustment.
Check that your monitor has VESA 75 or 100 mm holes and falls in the weight range; that’s the most common reason arms sag or won’t stay put.

- Want to free desk space

Skip it if you

Check price on Amazon Why pick Ergotron LX Single Monitor Arm?
Ergotron’s LX has been a reference monitor arm for years because it holds heavier screens steadily and adjusts smoothly. It supports curved and ultrawide monitors up to 34 inches and 25 lb.
It costs more than gas-spring clones, and its minimum weight is higher, so it’s not ideal for very light screens.
Great if you
- Have an ultrawide or heavy monitor
- Want very smooth, stable adjustment
- Want premium build
Skip it if you
- Have a light monitor under 7 lb
- Want the lowest price
- Have a very shallow desk

- Up to 34 in, flat or curved

Weigh the monitor without its stand
Arms have minimum and maximum weights. Too light and it drifts up; too heavy and it sags.
Check VESA holes
Most monitors use 75 or 100 mm patterns. Some need an adapter.
Check the desk
Clamps need a solid edge; glass desks and thin lips need reinforcement.
Eye level
Top of the screen at or slightly below eye level, about an arm’s length away.

Check price on Amazon Frequently asked questions about monitor arms
Will a monitor arm fit my desk?
Most clamp to desks up to about 3–4 inches thick with a solid edge. Check the clamp range and use a reinforcement plate on thin tops.
What if my monitor has no VESA holes?
Look for a VESA adapter bracket made for your model or a clamp-style adapter.
Do monitor arms help posture?
They make it easy to put the screen at the right height and distance, which helps neck strain.
Single or dual arm?
Buy a dual arm if you use two monitors; two singles also work.
Can arms hold ultrawide monitors?
Yes if within the weight and size rating. Ultrawides are heavy and need a stronger arm like the Ergotron LX.
How did we pick these monitor arms?
We compared supported screen sizes, weight ranges, VESA patterns, mount types and adjustment mechanisms from manufacturer specifications, and OSHA ergonomic guidance for monitor placement.
We have not hands-on tested these products; we compare published specifications, independent measurements and manufacturer documentation, and we update this page when models change. Read the full methodology.
