Ergotron HX Monitor Arm Review: Is It Worth It for Ultrawide Setups?

June 27 2025

If you’ve seen my Alienware AW3821DW review, you’ll know I touched briefly on the Ergotron HX monitor arm. Today, we’re taking a deeper dive into how this arm holds up for an ultrawide monitor, especially for those who want to use their setup for both sim racing and productivity.

Why I Chose the Ergotron HX

I never thought I’d spend this much on a monitor arm, but after researching options for my ultrawide, it became clear that a cheap arm could end in disaster. I didn’t want to risk damaging an expensive monitor just to save a few bucks on a mount. After reading countless positive reviews about Ergotron arms, I felt confident in this purchase—and months later, I can say it’s been worth every dollar.

If you’re interested in picking up this arm, I’ll have some links in the description below. They help support the channel if you decide to use them.

Unboxing and Installation

Inside the box, you get everything you need to mount the arm via grommet or clamp. I chose the clamp method since I wasn’t ready to drill a hole in my tabletop.

While the instructions recommend not mounting too close to the edge, I needed it close for my sim racing setup. To add support, I placed an extra piece of wood under the clamp—this may not be necessary depending on your desk’s thickness.

Setup was straightforward:

  • Mount the base

  • Insert the remaining arm pieces

  • Tighten with the included Allen key

For my setup, I didn’t fully tighten the bottom screw, allowing me to rotate the arm toward my rig. It’s not the safest method, so if you don’t need this flexibility, I recommend tightening it fully.

Adjustments and Fit

The Ergotron HX uses a standard VESA mount, making it easy to attach my ultrawide monitor. Once mounted, you can adjust tension at various points. I only adjusted the rotation tension since I don’t plan to use a portrait orientation for my ultrawide.

In terms of range:

  • The arm swings 18 inches left and right from the base center.

  • For my setup, 18 inches is just enough, although a few extra inches would have been perfect.

To maximize reach, I angled my sim rig slightly toward my desk, allowing the arm to fully extend without issue. Alternatively, using the grommet mount closer to the edge could provide more flexibility.

Cable Management

The arm comes with Velcro straps and a cover to keep cables tidy. The only improvement I wish for is for the cables to exit from the back of the arm instead of the side for a cleaner look.

Performance and Compatibility

The Ergotron HX handles the weight of my Alienware AW3821DW without any sag or drift, no matter how I position it. It can also support up to a 49-inch ultrawide, including the Samsung G9 series (though you’ll need the upgraded tilt head for that).

While I rarely tilt or swivel my monitor, the arm supports full movement:

  • Tilt up and down

  • Pan left and right

  • Rotate (if needed)

This flexibility makes it easy to adjust for different use cases, whether I’m sim racing or working.

Final Thoughts: Is the Ergotron HX Worth It?

Without this arm, my dual-use setup wouldn’t be possible. Being able to position my monitor exactly where I need it for sim racing while maintaining a clean workspace is a game-changer.

Yes, the price of the Ergotron HX is steep, but the build quality and peace of mind are worth it if you have an ultrawide monitor you plan to use heavily for both gaming and productivity.

If you’re looking for a reliable, premium monitor arm for your ultrawide, I highly recommend the Ergotron HX.
