3M Monitor privacy filter 38" 21:9 black PF380W2B

The 3M PF380W2B privacy filter is designed for 38-inch monitors with a 21:9 aspect ratio. Its Micro-Louver technology darkens the image when viewed from the side beyond a 60-degree viewing angle, helping keep on-screen data confidential while still giving a clear picture when viewed straight on.

The filter is double-sided, with one glossy and one matte side. The matte side reduces glare and helps hide fingerprints. The surface is scratch-resistant, and according to the manufacturer it filters about 35 percent of blue light, which may make longer working sessions more comfortable.

The package includes mounting strips and sliding attachment tabs, so the filter can be fitted and removed easily without leaving residue. The frameless design and landscape mounting give it a clean, understated look.
