ViewSonic VP-PF-3400 34-Inch Privacy Filter 20-Pack

The ViewSonic VP-PF-3400 is a privacy screen protector packaged in a 20-unit bulk set, purpose-built for ultrawide 34-inch monitors with a 21:9 aspect ratio. It is designed to restrict the viewable angle to approximately 60 degrees, effectively blacking out the screen for anyone not seated directly in front of the display. This makes it a practical solution for environments where sensitive data is routinely handled — including corporate offices, financial institutions, healthcare facilities, and government agencies — where visual hacking is a genuine security concern.

Beyond its privacy function, the filter features an anti-glare and anti-reflective surface treatment that reduces distracting reflections from overhead lights and nearby windows. This dual-purpose design means the filter contributes to both data security and workplace comfort during extended use. The durable construction is built to withstand the wear of institutional deployment, where filters may be repositioned or replaced across multiple monitors. The 20-pack format is clearly targeted at IT departments and procurement teams managing fleet-wide rollouts rather than individual consumers.
