Lenovo Kensington monitor privacy filter 34" 21:9 (4Z11U65815)

In open-plan offices and shared workspaces, sensitive information on your monitor is constantly at risk of prying eyes. Side glances from colleagues or visitors can compromise confidential emails, financial data, and client information. The Lenovo Monitor Privacy Filter for 34-inch ultrawide monitors applies a micro-louver technology that narrows the viewing angle to ±30°, so only you, sitting directly in front of the screen, can see the content clearly. With a simple application, you gain instant peace of mind without sacrificing display quality.

Who is it for

This privacy screen is designed for professionals handling sensitive data, such as HR managers, financial analysts, developers, and anyone working in a high-traffic environment. It is also ideal for remote workers who want to keep their work discreet at home or in cafés. The filter fits 34-inch monitors with a 21:9 aspect ratio, giving ultrawide displays the same level of protection as standard screens.

Tips

Before mounting, thoroughly clean your monitor screen to ensure the adhesive strips or tabs adhere properly. Align the filter carefully, starting from one edge to avoid air bubbles. When not using the filter, store it in its protective sleeve (if included) to prevent dust and scratches. If you need a brighter view, flip the glossy side forward; for glare-prone office lighting, use the matte side.
