Keep prying eyes at bay by protecting all your personal information on your computer when you use the Targus 20" Macbook Pro Privacy Filter Screen. This Targus 15" Privacy Screen protects your information with tiny vertical blinds on the surface of the screen, narrowing the viewing angle so information is only visible directly in front of the monitor. Onlookers will only see a dark blurry screen when attempting to view the information from a side angle. In addition, this privacy screen also shields indoor and outdoor glare!
