Overview
The Ergotron 45-682-290 LX Pro Desk Monitor Arm is a white single-monitor desk mount designed to position a display above the desktop while providing a wide range of height and viewing adjustments. Its articulated arm supports displays up to 34 inches and uses Constant Force technology for smooth monitor positioning.
Monitor Support and Adjustment
The arm supports a monitor weighing 4–22 lb (1.8–10 kg) and provides 13 inches (33 cm) of lift. The monitor can tilt through an 85° range, with 70° upward and 15° downward movement. A dedicated monitor pan provides 180° of movement, while the monitor itself can rotate 360° for landscape or portrait positioning.
Desk Mounting and Reach
The standard two-piece desk clamp mounts to compatible desktop surfaces, while the articulated arm provides up to 25 inches (64 cm) of extension. The base arm can pan through 360°, or 180° when the integrated rotation stop is engaged. This stop can help limit side-to-side arm movement near walls, partitions, or other obstacles.
VESA Compatibility
The monitor attachment supports VESA MIS-D 100/75 C mounting patterns, including 100 x 100 mm and 75 x 75 mm hole spacing. The mount is designed for a broad range of monitors as long as the display remains within the stated weight capacity.

- Supports displays up to 34 inches and 4–22 lb (1.8–10 kg)

Applications
The LX Pro Desk Monitor Arm is suited to office desks, home workstations, professional workspaces, and other single-display setups where adjustable monitor positioning can free space on the desktop.

DC Supplies Product Note
Check the monitor's actual weight before installation rather than relying only on screen size. Displays up to 34 inches can be supported, provided the monitor remains within the 4–22 lb capacity and uses a compatible VESA mounting pattern.
