Why is the Ergotron LX Pro Desk Quad Arm the best choice for a 4-monitor setup?
The Ergotron LX Pro Desk Quad Arm impresses as a professional 4-monitor desk mount due to its thoughtful construction and unique Constant Force Lift technology. Unlike conventional gas springs or screw systems, this technology enables completely stepless height adjustment without tools — and remains permanently stable. Whether in the home office, professional trading environment, or graphic design, anyone using four monitors benefits from maximum flexibility and a tidy desk. The slim aluminum design is crafted to blend into any modern office environment without appearing bulky. With a swivel reach of up to 660 mm, the screens can be positioned precisely within the field of view. Each arm can be individually raised, extended, and swiveled, allowing various screen configurations such as triangular or side-by-side arrangements to be implemented effortlessly. The high-quality manufacturing has been proven by passing the 10,000-cycle test according to BIFMA Level 2 standard.
How is the quad monitor arm attached to the desk?
The LX Pro quad monitor setup is mounted via an integrated desk clamp that attaches to desk edges with a thickness of 10 to 60 mm — without drilling or damaging the desk surface. The scope of delivery includes all necessary components: the LX Pro Dual Stacking Arm as the base with a large base and a 12-inch pole, two LX Pro Monitor Arm Expansion Kits for the third and fourth monitor, and two LX Pro Dual Side-by-Side Collars that can be mounted at any position on the pole. This allows large screens to be arranged in a triangle or smaller displays side by side. All components are available in the color options black, dark gray, and white. As an alternative to the desk clamp, the base can be replaced by a cable grommet option by choosing the LX Pro Dual Stacking Arm with bolt-through mounting.
Which monitors are compatible with the Ergotron LX Pro quad arm?
The Ergotron LX Pro Desk Quad Arm is compatible with monitors up to 27 inches diagonally that conform to the VESA standard FDMI MIS-D with a 75x75 mm or 100x100 mm hole pattern. Load capacity is 1.8 to 5 kg per individual monitor, with a total load capacity of 7.3 to 20 kg. Curved monitors may be restricted depending on housing height — the maximum external height of the stacked screen must not exceed 350 mm. For monitors larger than 27 inches, we recommend checking that the weight limit is met. Ergotron provides a ten-year warranty on the entire product. This bundle consists of a combination of different products — details on the individual components can be found in the technical specifications in the description.
