Frequently Asked Questions

q Will this arm hold TV that is 42" in screen size and weighs about 28 lbs? The model of my TV is LG 42ls5700.

No, your TV is not compatible with this arm as the weight of your TV is more than the weight that this arm can hold (25 lbs). We recommend the Interactive Arm, which extends 24" and can be fully retracted to 5.5" when not in use.

q What does the wall track option do?

The purpose of the wall track is to strengthen the installation of the arm by distributing the weight over a larger surface and also provide more vertical adjustability as the arm moves along the track when installed.

q Assuming I'll be mounting this to a stud behind drywall, do I need any accessories?

(5 out of 5)

by Leslye N, Burnsville, North Carolina, Oct 10, 2019

I use a Viewsonic 32 inch HDMI 4K monitor and this arm holds it perfectly. I have low vision 20/400, and needed the screen close so I can read the text. I'm using a MacPro 2013, the arm extends my monitor 28 inches from the wall and holds its position. The product is solid, well constructed and I would highly recommend it.

Dental office vibe but it works perfectly

by ERIC S, Massachusetts, May 03, 2018

I mounted two 19" monitors on this arm using the adapter kit, and the arm holds them in position without any drift. It is great having a separate arm for the keyboard so the vibration from typing does not make the screens wiggle. I'm a fan.

Great design and service

by ES, Washington, Sep 11, 2016

I have used a LX Sit-Stand Arm for three-years with a 27" monitor. I purchased another LX Sit-Stand arm for a second 27" monitor on my desk because I had been so pleased with Ergotron's design and build quality of the first unit. The arm is easy to install and adjust. Being able to move both monitors up, down, left, right, and change orientation independent of each other is fantastic. Ordering from Ergodirect was smooth and the item arrived quickly.

Excellent solution for a cabinet TV

by JP, Oregon, May 27, 2016

We bought this to hold a TV in our kitchen cabinet over our refrigerator. It works perfectly to hold a 32" screen and compared to other cabinet TV mounts, is smooth to move in and out, stable, and an elegant solution.

Great arm for hard to work area

by Bill K, Minneapolis, May 06, 2015

This arm works great for our 40 inch tv to let it be moved into an area when we're watching tv and moved out when we're entertaining friends.
