CHAPTER 1: Using Your Gateway Flat-Panel Monitor

Ergonomic guidelines
The recommended screen positioning is based upon the following guildelines. These guidelines
are based on available scientific literature and published standards.
Screen height
The recommended screen height for displays (except in special circumstances, such as for bifocal
use) is that the top of the display should be set at or slightly below (about 1 inch or 25 mm)
your eye level while you are sitting in a comfortable working posture. This guideline places the
center of the screen at an ideal 15° to 20° viewing angle for most desktop displays. If the display
has multiple users, the screen height should be easily adjustable to accommodate each user’s
height and preference.
Screen tilt
The screen should be tilted so your line of sight is perpendicular to the screen. This angle creates
the most consistent viewing distance when scanning from the top of the screen to the bottom.
You may need to adjust lighting to avoid screen glare when the screen is tilted upward.
Screen distance from user
The screen should first be placed at arm’s length from the user, then adjusted back and forth
to suit individual preference.
