The Targus 24" Widescreen LCD Monitor Privacy Filter protects 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 from a side angle. The privacy filter also blocks the glare to help reduce eyestrain. 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. The Targus privacy screen is highly portable and easy to use.
