Two monitors on a desk without arms is a compromise — screens at the wrong height, a cluttered desk surface, and no ability to adjust your viewing angle. The Invision MX400 Dual Monitor Arm is the professional solution — a dual desk mount for 19–32-inch screens with VESA 75/100mm compatibility, tool-free height adjustment, full tilt/swivel/rotate, and a desk clamp that frees up your entire desk surface.
What Makes the MX400 Stand Out?
- Dual monitor support — holds two screens simultaneously from a single desk clamp
- 19–32-inch screen compatibility — covers the full range of modern monitor sizes
- VESA 75/100mm — the universal mounting standard compatible with virtually all monitors
- Tool-free height adjustment — adjust both screens to the perfect ergonomic height without tools
- Full tilt, swivel, and rotate — position each screen at any angle, including portrait mode
- Increased load capacity from 2–9kg — handles heavier monitors that lighter arms can’t support
- Desk clamp mount — no drilling required, clamps to the desk edge

Real-World Usage Situations
💻 The Home Office Dual-Screen Setup
A dual monitor setup is one of the most significant productivity upgrades available for knowledge workers — research shows it can increase productivity by 20–30%. The MX400 takes that setup to the next level by positioning both screens at the perfect ergonomic height and angle, freeing up the desk surface beneath them, and allowing you to adjust the configuration instantly as your work changes.

🎮 The Gaming Setup
Dual-screen gaming setups benefit enormously from monitor arms — the ability to position screens at the perfect angle and height for gaming, then quickly reconfigure for work or content consumption. The MX400’s full tilt, swivel, and rotate allows you to find the exact configuration that works for your gaming position, and the 2–9kg load capacity handles gaming monitors that are typically heavier than office screens.
🏢 The Professional Workstation
Designers, video editors, developers, and financial analysts who work with multiple screens benefit from the MX400’s ability to position each screen independently. One screen in landscape for the main work, one in portrait for code, documents, or reference material — the rotate function makes this configuration effortless.

📊 The Trading & Finance Desk
Financial traders and analysts who monitor multiple data streams simultaneously need screens positioned for maximum visibility and minimum neck strain. The MX400’s independent adjustment of each arm allows precise positioning for a trading desk configuration, and the tool-free adjustment means you can reconfigure quickly as your monitoring needs change.
🏠 The Compact Home Office
In a small home office, desk space is precious. The MX400’s desk clamp mount frees up the entire footprint of two monitor stands — typically 30–40cm of desk depth per monitor. That’s a significant amount of usable desk space recovered, making a small desk feel dramatically more spacious and organised.

Excellent Value at £79.20
Dual monitor arms with comparable screen size range, load capacity, and adjustment range from established brands (Ergotron, Amazon Basics, Fully) typically retail at £80–150+.
