downward when looking at the middle of the display.
• Adjust the display brightness and/or contrast to a comfortable level for enhanced text
readability and graphics clarity.

• placing your display in such a way that the side faces the window or any light source
• minimizing room light by using drapes, shades or blinds
• using a task light
• changing the display’s viewing angle
• using a glare-reduction lter
• using a display visor, such as a piece of cardboard extended from the display’s top
front edge
• Avoid adjusting your display to an awkward viewing angle.
• Avoid looking at bright light sources, such as open windows, for extended periods of time.
