The 4Vu Privacy Screen is designed to fit the HP EliteDisplay E243i. To protect your information, tiny vertical blinds on the surface of the privacy screen narrow the viewing angle so data is visible directly in front of the monitor up to 30° away from the center of the screen. Onlookers will only see a dark unclear screen when attempting to view the information from a side angle. In addition to providing security, the screen also blocks glare to help reduce eye strain. The 4Vu Privacy Screen can be easily attached by using clear double-sided adhesive strips designed for LCD filters. Highly portable and easy to use, the 4Vu Privacy Screen prevents onlookers from seeing valuable information often viewed on a display.
