Ergonomic tips: Adjust the monitor height so that the top of the screen is atβor slightly belowβeye level. Your eyes should look slightly downward when viewing the middle of the screen. Position the monitor at least 20 inches (51 cm) from your eyesβabout an arm's length distance.
The keyboard and mouse should be in line with your elbows. A keyboard handrest can prevent the wrist from bending.
