If you install the monitor near a window, use curtainsor blinds to block the sunlight. You can adjust the brightness and contrast controls on the monitor as theroom lighting changes throughout the day.Where it is impossible to avoid reflections or to adjust the lighting, an antiglare filter placed over the screenmight be helpful.
