PORT professional privacy filters are designed to preserve the confidentiality of the information displayed on a computer screen. Once positioned, only the user located in front of the screen can view the information, while anyone located laterally at more than a 30° angle will see only the black opaque filter. Perfectly adapted for mobility, it ensures the confidentiality of computer screens, especially at work and during travel. It is ideal for offices, open spaces, airports, airplanes, trains, cafes, and other public places. Work productively anywhere without worrying about prying eyes. Very simple to install, it can be removed and repositioned easily to share your screen with others. Thin and durable, the filter also provides protection for the screen against scratches, dirt, and shocks.
