The 4VuPrivacy Screen is designed to fit 14" widescreen laptops with 16:9 ratio screens. 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 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. Highly portable and easy to use, the Targus privacy screen protects valuable information on a laptop and LCD monitor from onlookers. The Targus laptop 4VuTM Privacy Screen can be easily attached by using one of the four convenient methods provided.
