Shield personal information on your computer from curious onlookers in public with the Targus 20" 16:9 Widescreen LCD Monitor Privacy Filter Screen. This Targus 20" 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 unclear screen when attempting to view the information from a side angle. In addition, this privacy screen also blocks indoor and outdoor glare!
