The Ergotron LX Pro is a practical, effective, easy-to-use monitor arm. Ergotron achieves this ease-of-install with clever, yet simple, engineering.
The LX Pro’s clamp mechanism, which secures the monitor to a desk, takes the extra step of providing a comfortable handhold that makes it easy to work the clamp without tools. The arm’s two sections, meanwhile, simply slip into place. Ergotron also provides thumb screws for attaching the arm’s VESA mount to the back of your monitor.
Depending on your monitor, you may need to use the included hex wrench to tighten the components. Otherwise, installation doesn’t require tools.
The arm’s desk clamp mechanism is wide, which is important. Clamps with a small surface concentrate more force on your desk and cause damage if over-tightened. A wider clamp better distributes the force. That means the LX Pro is less likely to damage weaker desks (though caution when tightening the clamp is recommended).
Fortunately, the arm’s ease of installation doesn’t lead to functional downsides. The arm can support monitors up to 34 inches diagonally that weigh up to 22 pounds. The arm also lifts up to 13 inches, tilts up to 85 degrees, and can swivel and rotate to a full 360 degrees. Cables are routed through channels in the arm and secured by sturdy detachable cladding. Ergotron provides a 10-year warranty.
The LX Pro even fixes our gripes about its predecessor, the Ergotron LX. The LX Pro’s base is more compact, the white colorway now has a color-coordinated VESA mount, and the new design is more attractive. The only downgrade compared to the old Ergotron LX is a lower maximum weight (the LX could handle up to 25 pounds). But that’s unlikely to matter, as 32-inch and 34-inch monitors usually weigh 15 pounds or less.
The LX Pro’s $209 MSRP is enough to make shoppers think twice, but it’s great value for money. The arm’s overall build quality feels competitive with more expensive monitor arms, such as the Humanscale M2.1.
That makes the Ergotron LX Pro an easy recommendation. It’s simple to set up, looks nice, works well in day-to-day use, yet remains affordable. We already liked the Ergotron LX, but the LX Pro is a great upgrade.
