The Targus 19.5" Widescreen LCD Monitor Privacy Filter is designed to fit 19.5" 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 45 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 filter also blocks the glare to help reduce eye strain. The Targus LCD Monitor Privacy Filter 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 filter in place. Users can position the tabs so the filter easily slides on and off. The new under bezel tabs attaches to the privacy screen, which then slides under the bezel of your laptop for a clean, simple look. Highly portable and easy to use, the Targus privacy screen protects valuable information on a laptop and LCD monitor from onlookers.
