A single arm frees desk space and lets you set the screen at eye level. Every pick holds one monitor, from the premium end down.

Rankings weigh max screen size, max load per arm and monitors as the makers state them; if a maker skips VESA, the guide says so rather than guess, since we have not benched them.

Our Picks

Premium Pick1 of 5

Ergotron LX Single Monitor Arm

Ergotron's LX holds 7 to 25 lb screens up to 34 inches with 13 inches of lift.

Best for

Buyers for whom price is not the deciding factor, since the ErGear heavy duty costs less.

Skip if

Skip it if price comes first: the ErGear heavy duty cost less when we checked.
Ergotron LX Single Monitor Arm

Why we like it

It ships with a two-piece clamp and a grommet mount. It matches the Ergotron LX Pro on screen size limit (34 in). Its 25 lbs load rating ranks fourth of 5 here, behind the TitanLift (44 lbs) and ahead of the Ergotron LX Pro (22 lbs).

It shares a 75x75 / 100x100 vesa with the Ergotron LX Pro and ErGear heavy duty; the TitanLift goes with a up to 100x100 vesa. You get a two-piece clamp and grommet mounting here, which sets it apart from the ErGear heavy duty and its a dual C-clamp or grommet mounting. Check the back of your monitor for a 75x75 / 100x100 VESA pattern before ordering the Ergotron LX; curved and some slim monitors need an adapter. It was the most expensive pick when we checked, so weigh what it adds over the Ergotron LX Pro.

Ergotron LX Pro Premium Single Monitor Arm

Ergotron's LX Pro holds 4 to 22 lb screens up to 34 inches with 13 inches of lift.

Best for

Buyers who want 4 to 22 lb range.

Skip if

Skip it if screen size limit matters most to you; the TitanLift offers 49 in.
Ergotron LX Pro Premium Single Monitor Arm

Why we like it

The grommet mount is sold separately. On screen size limit it ties with the Ergotron LX at 34 in. On load rating it trails the group at 22 lbs, while the TitanLift is rated for 44 lbs.

Like the Ergotron LX and ErGear heavy duty, it has a 75x75 / 100x100 vesa, while the TitanLift uses a up to 100x100 vesa. No other pick in this guide offers a two-piece clamp mounting; compare the HUANUO ultrawide, which has a C-clamp or grommet mounting. Check the back of your monitor for a 75x75 / 100x100 VESA pattern before ordering the Ergotron LX Pro; curved and some slim monitors need an adapter.

Confirm your desk edge fits the Ergotron LX Pro's clamp range and has no rear lip or drawer rail in the way. When we checked, only the TitanLift and cheaper picks cost less, and the Ergotron LX cost more.
