Follow these guidelines for adjusting the monitor:
●Place the monitor in a location where glare and bright reflections are eliminated. Try to avoid bright light sources in your field of vision.
●Place the monitor directly in front of you to avoid twisting your neck and torso.
●To avoid craning your neck forward to view text that is too small, experiment with adjusting the percentage of zoom to 125 percent or higher. For computer use, you may find character height of three millimeters to four millimeters most productive for reading.
WRONG Do not crane your neck forward.
TIP: On some computers, the zoom setting can be adjusted up and down by holding down the 
ctrl key and rolling the mouse scroll wheel or by using the zoom gesture on the touchpad.
