3M Privacy Filter for 19" Standard Monitor

Overview

The 3M PF190C4B is a privacy filter designed for 19-inch monitors with a 5:4 aspect ratio, covering an active viewing area of 14.83 inches wide by 11.89 inches high. It uses microlouver technology to narrow the viewing angle, ensuring that only the person directly in front of the screen can see the content clearly, while side views appear dark and obscured. This makes it an effective solution for protecting sensitive information in shared or public environments.

The filter features a reversible design with one glossy side that maintains image clarity in softer lighting and a matte side that reduces glare and hides fingerprints under bright overhead lights. Additionally, it reduces a portion of blue light to ease eye strain during extended use without affecting color accuracy or sharpness. Installation is simple, with slide mounts for easy removal and adhesive strips for a more permanent setup.
