Create the ultimate ergonomic comfort while freeing up valuable desk space with this triple-monitor arm. You can set up three computer monitors (each up to 24”) and create a surround setup to maximize productivity. The triple-monitor arm works with all VESA mount compliant monitors including Acer®, HP® and Samsung.

Greater comfort and productivity

Enhance your productivity and work in comfort with a multi-screen setup. The triple-monitor arm supports three displays (13” to 24”) and lets you adjust the position of your monitors with 360° rotation and + 30° / -30° tilt for each monitor.

Choose from landscape or portrait screen rotation to customize your workspace. You can set up three displays in landscape position to create a curved surround effect or ‘cockpit style’ for comfortable viewing. This setup is ideal for editing videos or photos or working with multiple documents at the same time. For applications such as web design or coding, you may choose an alternate setup, for example with the center monitor in landscape mode and the outside monitors in portrait position.

Robust solid-steel construction

Made of strong and durable steel, the triple-monitor stand securely supports three separate computer monitors up to 24” in size. It supports a weight capacity of up to 17.6 lb. or 8 kg for each monitor.

Easy adjustment

The triple-monitor arm is VESA mount compatible, working with most computer monitors up to 24”. It’s easy to set up using the included desk clamp or grommet mount and also comes with cable management clips to keep your cables neat and tidy.

You can adjust the display height without tools. You simply turn the adjustment knob to adjust the monitor height, keeping all three monitors at the same level.

The ARMTRIO is backed by a 5-year warranty and free lifetime technical support.
