The 4Vu™ Privacy Screen is designed to fit the Dell™ U3417W. To protect your information, tiny vertical blinds on the surface of the privacy screen narrow the viewing angle so data is only visible directly in front of the laptop 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 an 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. 30° Viewing Angle Even in public places like hotel lobbies, airplanes, or cafes, the 4Vu Privacy Screen keeps your data safer from prying eyes. Your content is visible only to the person directly in front of the screen and up to 30° on either side. You have full clarity and visibility, while onlookers or passersby see only a black screen. Reduced Glare, Even in Bright Rooms Our Low-Reflective Coating reduces glare and improves light transmittance under most viewing conditions. Suited for Workplace or Personal Use One study found that employees are 50% less productive when their visual privacy is at risk, and that two in three employees expose sensitive data outside the workplace.1 With more of us working in open office settings, on-the-go, or in unsecured environments, visual privacy is a critical consideration for employers and employees alike. Privacy screens add a layer of protection that encourages productivity at the same time it protects confidential information.
