# Ergotron monitor arms ## Overview I tend to use Ergotron arms for my monitors and pen displays. * Ergotron HX - I have 4 of these arms. * Ergotron LX - I have 1 of these arms. ## Ergotron HX For >=24" pen displays, I use the **Ergotron HX**. This is a very well designed and rugged arm. I use it with: * Wacom Cintiq Pro 27 * Huion Kamvas 24 Pro 4K * Many 32" monitors ## Ergotron LX For \~22" pen displays I use the Ergotron LX. It's certainly not as rugged as the Ergotron HX, but it has been reliable and has a good range of motion. ## Wobble * All monitor arms will have some wobble if you draw on the pen display. * The **Ergotron HX** has less wobble than the **Ergotron LX**, but still has some wobble. ## Reduce wobble The way I reduce wobble when drawing with monitor arms (regardless of brands) is simple. First I lower the monitor arm as close to the desktop of possible. If the bottom edge makes contact with the desktop - this alone will help stabilize the display and remove some amount of wobble. Sometimes it's not possible to make the bottom edge of the tablet make contact with the desktop. Or perhaps the contact is not stable enough. When this happens I roll up a towel and place it under the bottom edge. This provides more contact and stability. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
