The Problem:

You've heard a lot about ergonomics - being comfortable when you're using your computer. That means such things as having a good chair at the proper height, supporting your wrists at the keyboard, and being sure your monitor is at the correct viewing angle. All the recommended ergonomic factors focus on how you relate to your computer keyboard and monitor. But what about the equipment itself? Considering how many hours a day you look at your computer monitor, how can you be sure you have the best possible monitor to reduce eyestrain, improve your productivity and make your computing time more enjoyable?

The Solution:

I encourage my clients to spend the extra money and buy a quality LCD monitor. The parameters that define different monitors sound very technical but you do need to understand how some of the key features of your monitor are measured. Once you have decided on the features you want, your final selection of a monitor will still probably be a matter of personal preference. So, it is best to go shopping and actually compare a few monitors, preferably side by side. Here is a list of key features to consider in selecting your next monitor.

Connectivity - LCD monitors will generally have one or both of the main types of connectors (Standard VGA 15-pin, or Digital Visual Interface [DVI]). Check the user manual for your computer to be sure that the connector on the monitor will match the video output connector on your computer.

Size - Bigger is not always better. Bigger monitors will have bigger price tags but they won't necessarily be easier on your eyes. After you have considered the space you have on your desk and whether the price is within your budget, compare several monitors to see how readable the screen actually is.

Resolution - Measured in pixels (e.g. 1024 x 768), this is another one of those personal preference factors. LCD monitors will have maximum resolution. That is, the dots on the monitor will be the same number of dots that are being sent from the computer. At this resolution, you will have the clearest view. Keep in mind that a higher resolution means that the items displayed will look smaller, but you will have more area to work with. (NOTE: Windows settings can also be adjusted to accommodate high resolutions so things don't look too small.)

Brightness - Measured in "cd/m2" (e.g. 300 cd/m2). Higher is better, especially if the monitor will be used in an area with bright lighting.

Contrast - Measured by a ratio (e.g. 400:1). A greater ratio is better. Items on your screen won't look washed out and colors will be more clear.

Viewing Angle - Measured in degrees (e.g. 170o). The greater the viewing angle, the more consistent the picture quality will be when you look at the monitor from different angles.

Response Time - Measured in milliseconds (e.g. 19ms). Lower values are better for multimedia, games, and movies, all of which require quick action on the monitor.

Extras - Some monitors will have added features such as built-in speakers, TV tuners, picture-in-picture, and wall mounts. Only you can decide if they are useful enough to warrant buying them.
