Monitor Mount Ergotron HX Series 45-475-216

The Ergotron HX Series 45-475-216 monitor arm adds flexibility and improved ergonomics to a monitor or TV, supporting screens up to 49" (124.5 cm) and a maximum weight of 19 kg. The redesigned post and folding arm free up desk space while allowing extension/retraction, height adjustment and screen rotation for portrait or landscape viewing. Cable routing is integrated into the arm to keep cables tidy.

Advantages

The HX monitor arm reduces eye, neck and back strain by enabling ergonomic positioning and easy adjustments. Constant Force motion technology provides smooth, low-effort height and tilt movement. The arm supports large displays up to 19 kg and passes Ergotron’s 10,000-cycle motion test for long-term reliability. Additional features include a rotation-stop that limits swivel to 180° to prevent contact with the wall and integrated cable management.

Suitable for

• Office workstations requiring ergonomic monitor positioning
• Home offices with large monitors or TVs up to 49"
• Graphic design, photo editing and document review (portrait mode)
• Multi-user desks where easy adjustment and space saving are needed

Rotate the screen into portrait mode when needed and use the rotation-stop on the base to limit swivel and avoid wall contact. Route cables under the arm and through the extension to keep them organized.

Recommendations

Ensure the monitor weight does not exceed 19 kg and confirm the display’s VESA pattern is within 75 x 75 mm to 400 x 400 mm before installation. For multi-monitor setups, upgrade with the HX Triple Bow Kit as required.
