Overview
The Ergotron LX Pro Desk Monitor Arm, Tall Pole, Grommet Mount, part number 45-709-293, is a single-display mounting solution finished in dark grey. It combines an articulated monitor arm with a taller vertical pole and a grommet-based desk attachment, allowing users to position a compatible monitor above the desktop.
Part of Ergotron's LX Pro series, this configuration is designed for workstations that require flexible monitor positioning and a mounting arrangement through a desk opening. The extended pole provides additional mounting height compared with the standard-pole configuration.
Monitor Adjustment and Positioning
The arm uses Ergotron Constant Force technology to support smooth monitor repositioning. Its articulated design allows the screen to move vertically, extend away from the mounting point, and rotate to accommodate different workstation layouts.
The arm provides up to 33 cm of lift and extends up to 65.6 cm. Monitor tilt, panning, and rotation adjustments help users position the display for different tasks. The base arm can rotate through 360 degrees, with a rotation stop available to limit movement to 180 degrees.
Display Compatibility
The LX Pro Desk Monitor Arm, Tall Pole, is designed for one compatible display with a typical screen size of up to 34 inches and a supported weight between 1.8 and 10 kg.
The monitor must use a compatible VESA MIS-D mounting pattern with 75 × 75 mm or 100 × 100 mm mounting holes. Check the display's weight, mounting interface, dimensions, and clearance before installation. The manufacturer's stated screen size is a guideline; the supported weight and physical fit must also be considered.
Desk Mounting and Installation
This configuration uses a grommet mount to secure the arm through a suitable opening in the desk. The installation location must provide sufficient space for the mounting hardware and allow the arm to move through its intended range.
The tall pole measures approximately 30.4 cm. This configuration is useful when additional vertical mounting height is needed compared with a shorter-pole version. Before installation, confirm that the desk opening and desktop construction are compatible with the supplied mounting arrangement.
Cable Management
The arm incorporates cable management to help route monitor cables along the mounting assembly. Organizing cables along the arm can reduce loose cabling around the workstation. Ensure that the cables have sufficient slack for the full range of movement without pulling on the monitor connectors.
Key Features
- Tall-pole configuration: Includes a 30.4 cm pole for additional mounting height.
- Grommet desk mounting: Attaches through a compatible desk opening rather than relying on an edge-mounted clamp.
- Constant Force technology: Supports smooth adjustment of the mounted display.
- Flexible screen positioning: Provides height adjustment, extension, tilt, panning, and monitor rotation.
- Integrated cable management: Helps route monitor cables along the arm assembly.
Applications
The LX Pro tall-pole monitor arm can be used in office workstations, administrative desks, home-office setups, technical work areas, and other environments where a single display requires adjustable positioning. Its grommet mounting arrangement is particularly relevant to desks designed with a suitable mounting opening.
DC Supplies Product Note
This model combines the tall-pole configuration with grommet mounting. When selecting between Ergotron LX Pro variants, check both details in the part number and product description: versions with a standard pole, tall pole, and different desk-mounting arrangements are distinct configurations. Confirming the mounting method and available desk opening before ordering helps avoid selecting an incompatible version.

Frequently Asked Questions
What is the difference between the tall-pole and standard-pole versions?
The tall-pole configuration includes a 30.4 cm pole, compared with the shorter 13.5 cm pole listed for the standard-pole LX Pro Desk Arm. The additional pole height can provide more flexibility when positioning the monitor above the desk.
How many monitors does this arm support?
This model supports one display within the specified weight range of 1.8–10 kg. It is not a dual-monitor arm.
Does this model use a desk clamp?
No. The 45-709-293 configuration uses a grommet mount designed for installation through a compatible desk opening.
Will this arm fit a 34-inch monitor?
The arm is specified for displays typically up to 34 inches. The monitor must also meet the weight limits and have a compatible VESA mounting pattern. Screen dimensions and available clearance should be checked before installation.
Can the monitor be rotated into portrait orientation?
The monitor pivot supports 360-degree rotation. Actual positioning depends on the display's dimensions, mounting interface, and clearance around the workstation.
