3M 40" Universal Privacy Filter, 21:9

The 3M Privacy Filter PF400W2E is engineered for large desktop monitors, specifically fitting 40-inch displays utilizing a 21:9 widescreen aspect ratio (948 mm by 401 mm). This filter enables confidentiality by narrowing the effective viewing area of the screen. When viewed directly from the front, screen clarity remains uncompromised for the user. Viewers positioned outside the approved viewing angle perceive a darkened screen.

This accessory features a reversible design, allowing the user to select either a glossy finish for enhanced visual clarity or a matte finish for superior anti-glare performance. The material provides essential protection for the screen surface, offering resistance against scratches, smudges, and fingerprints. It also incorporates technology designed to reduce display glare and lessen the amount of blue light emitted, contributing to improved viewing comfort during prolonged use.

Installation is straightforward, supporting either desktop attachment or frame-mitted mounting methods appropriate for frameless monitors. The design facilitates simple attachment and allows the filter to be removed easily when necessary—such as when sharing screen content—without leaving adhesive residue on the display surface. It is compatible with both LCD and CRT monitor technologies.
