There is more to computer monitor arms than simply saving valuable desk space. They are ergonomic tools that help people sit and function more comfortably and productively at work. Monitor arms, whether they are built for LCD flat screens or CRT ones, can help prevent eyestrain, upper back problems, headaches and neck tension.

To effectively position the monitor, the arm should be able to set it at least 25 inches from the viewer's eyes and either equal to below horizontal eye level by 15° or 50°, depending on comfort. The arm must allow the monitor to be tilted with the top of the screen a bit farther back from the eyes than the bottom (unless glare from overhead lights impedes any viewing area of the screen). Some computer monitor arms are more adjustable than others, so take these small but significant movements into consideration when purchasing a computer arm for your office.

Computer monitor arms should be placed in the central viewing area of the desk, in direct line with the keyboard, mouse and document holder. While people who infrequently glance at the screen can afford to place it either to the right or left, those who utilize the computer for long periods of time can strain their neck and cause undue muscle tension in their upper back and shoulders if it is not centered. Designers and engineers who utilize multiple computer screens to perform their work may wish to purchase computer monitor arms that can handle more than one monitor at a time.

Increased Functionality of Many Computer Monitor Arms
In addition to the simple vertical and horizontal adjustments common with most arms, some designs include a variety of different features that enhance their overall usability. Some are built with optional document holders, while others come with a keyboard and mouse tray already attached. These can be incredibly useful in areas of the room that need a computer station but not necessary a desk. In office areas where users may need to interact with others, such as clients, other employees or bosses, the arm can swivel into the other person's view or can be set off to the side if the desk area needs to be used for other purposes.
