- How is the LX Pro different from the standard LX?
- The Pro adds a lockable joint and refined cable management to the same single-arm design. The standard LX is cheaper but its joints are not lockable.
- What screen sizes and weights does it hold?
- It mounts one screen on a 75x75 or 100x100 VESA pattern. Check Ergotron's weight and size limits for your monitor before buying, since large ultrawides may exceed them.
- Does it work on a standing desk?
- Yes. It clamps or grommet-mounts to the desk edge, so it moves with a sit-stand desk. Confirm your desk thickness and edge fit first.
- Is the lock easy to use?
- The lockable joint lets you fix the arm's position with a simple adjustment. It is meant for shared desks where the screen should stay put.
- What is in the box?
- The arm, desk clamp and grommet mount, VESA plate and mounting hardware. A monitor and tools for some steps are not included.
- Can it hold a heavy monitor without sagging?
- The aluminum arm is rated for substantial monitors, but tension must be set for your screen's weight. Very heavy or very light screens may need careful tuning.
