Monitor arms, also called "swivel arms" or "swing arms," provide an adjustable arm attached to a platform on which you place your monitor. This allows you to easily position the monitor at the proper focal distance and viewing height. You can also reposition the monitor depending on whether you're standing or sitting (or if you move into different positions throughout the day). Monitor arms can free up desk space by lifting the monitor off of the desk, and allow you to swing the monitor out of the way to provide an unobstructed forward view (good for bankers, managers, or anyone else who interacts with customers or employees).
Monitor stands, also called "monitor risers" or "monitor blocks," provide a platform upon which a user can place a monitor to provide additional height, thus bringing the monitor into the recommended position. Many monitor stands are height-adjustable, and some feature drawers or cut-out areas underneath to increase available desk space.
CRT (Cathode Tube Display) Monitors are the traditional monitors that most people associate with computer use. They feature a curved glass display housed in a rather bulky and space-consuming box.
LCD (Liquid Crystal Display), or "flat screen," monitors, are gaining popularity quickly as they feature a clean display and are far less space-consuming than their CRT counterpart. LCDs are considered ergonomically superior to CRTs.
