Targus Widescreen 21.5" Privacy Screen ASF215W9EU-80 - A 21.5-inch 16:9 monitor privacy filter designed to protect sensitive on-screen information. It narrows the viewing angle so only the person directly in front can see the display clearly. The anti-glare coating reduces reflections and improves viewing comfort in bright environments. A built-in blue light filter helps reduce eye strain during extended use. It offers multiple installation options including adhesive strips and mounting tabs for easy setup.
