3M PF190C4B

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.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
