The Targus 19” Widescreen LCD Monitor Privacy Screen is designed to fit 19” widescreen LCD monitors. To protect your information, tiny vertical blinds on the surface of the screen narrow the viewing angle so data is only visible directly in front of the monitor up to 30 degrees 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 privacy screen also blocks the glare to help reduce eye strain. The Targus LCD Monitor Privacy Screen can be easily attached by using clear adhesive strips designed for LCD screens or with the included tab guides that stick to the edge of the LCD screen to hold the screen in place. Users can position the tabs so the screen easily slides on and off. Highly portable and easy to use, the Targus privacy screen protects valuable information from onlookers.
