An LCD monitor arm supports a flat screen monitor and holds it from a fixed surface. It consists of a four-bolt plate that fastens to the back of the monitor, a stand, and mounting hardware. It is installed on surfaces such as computer tables, walls, or ceilings. It usually has a swivel and tilt attachment that allows the monitor to face different directions. It is used to save desktop space, improve visibility, and provide a more ergonomic viewing position.
A Clamped LCD monitor arm uses a clamp to secure the monitor to a table, computer desk, post, or rail. It is easy to install and remove, but not very stable. It is usually designed for temporary installation.
A Screw-on LCD monitor arm provides a more permanent installation. The arm can be screwed on a table, wall, or ceiling. It is designed for permanent or semi-permanent installation.
A Standalone LCD monitor arm has a wide base that can support both the mount and the monitor. It is commonly used on computer tables and desktops. It allows less movement than other monitor arms.
