Ergotron HX Desk Monitor Arm Matte Black

Ergotron HX Desk Monitor Arm Matte Black (45-475-224) - 10 Years Local Singapore Warranty

Heavy-Duty Support for Large and Ultrawide Displays

The HX Desk Monitor Arm is a premium heavy-duty mount engineered to support large, ultrawide and curved displays weighing up to 19.1 kg (42 lbs). Built for ergonomic comfort, flexibility and durability, it helps create a cleaner, more efficient workspace while handling demanding professional and gaming setups. Its robust construction ensures smooth movement and stable positioning even with the heaviest screens.

Smooth Motion with Constant Force Technology

Ergotron's patented Constant Force technology lets users adjust monitor height, tilt, pan and rotation with effortless fingertip movement, then keeps the display balanced and secure. With roughly 29.2 cm (11.5") of height adjustment, 59.9 cm (23.6") of horizontal extension, a tilt range of 70 degrees back and 5 degrees forward, 180-degree pan and 360-degree screen rotation, the arm adapts to virtually any viewing need while reducing strain during long sessions.

Premium Matte Black Build and Cable Management

Finished in a sleek matte black finish, the HX arm delivers a sleek, professional appearance suited to modern offices, gaming rigs and enterprise environments. Its premium-grade aluminium and metal construction is engineered for continuous commercial use and long-term motion-cycle reliability. Integrated under-arm cable management keeps wires organised and hidden, while the folding arm retracts compactly over the base to maximise desk space.

Broad VESA Compatibility and Versatile Mounting

The HX supports VESA patterns of 75 x 75, 100 x 100, 200 x 100 and 200 x 200 mm, accommodating flat, ultrawide and curved monitors up to around 49 inches depending on weight. Both desk-clamp and grommet mounts are included, fitting desks roughly 1-6 cm thick. An optional HD Pivot is recommended for extremely heavy curved displays such as the Samsung Odyssey G9 series, and the arm works with HX multi-monitor expansion kits.

Built for Demanding Workstations

Ideal for trading and finance desks, ultrawide gaming setups, creative editing, enterprise hot-desks and engineering workstations, the HX combines stable support with effortless repositioning. It ships with the monitor arm, extension arm, monitor pivot, desk clamp, grommet mount and mounting hardware, providing everything needed to build a comfortable, space-efficient heavy-duty workstation.
