3M PF340W2B Privacy Filter for 34" 21:9 Ultrawide Monitors

The 3M PF340W2B Privacy Filter is the ultimate solution for professionals who need to protect sensitive information without compromising on screen quality. Designed specifically for 34-inch ultrawide monitors with a 21:9 aspect ratio, this privacy filter combines industry-leading privacy technology with a clear, vibrant display experience. Whether you work in finance, healthcare, software development, or any field where confidential data is part of the daily workflow, PF340W2B helps you keep information secure in busy workspaces, open-plan offices, coffee shops, or shared desks. With 3M’s trusted microlouver privacy technology at its core, this filter limits the viewing angles from the sides, so your data remains visible only to you while anyone off to the side sees a darkened, unreadable screen. At the same time, it preserves the sharpness, color accuracy, and brightness you expect from your ultrawide monitor, ensuring that your daily tasks aren’t hindered by privacy measures.

Beyond privacy, PF340W2B is engineered for comfort and productivity. The ultrawide format presents information in expansive layouts, making it ideal for multitasking, dashboards, coding windows, and complex data analysis. The filter’s advanced coatings help minimize glare and reflections from overhead lights or sunlight streaming through windows, reducing eye strain during long work sessions. You’ll notice that colors stay true when viewed straight-on, and text remains crisp, which is essential for reviewing documents, financial spreadsheets, or design work that benefit from wide-screen visibility. The combination of privacy and clarity means you can collaborate more confidently in shared spaces—without worrying about accidental disclosures or distracting reflections that break your focus.

PF340W2B is also designed for everyday practicality. It’s slim, lightweight, and built to survive the daily grind of desk life, with a durable surface that resists scratches and smudges. Cleaning is simple: a quick wipe with a microfiber cloth keeps the screen clear and the privacy filter performing at its best. The installer-friendly design makes it feasible to apply and remove without leaving adhesive residues or requiring specialized tools, so you can switch between a privacy-enabled display and an open-screen presentation posture as needed. This flexibility is especially valuable for IT departments deploying privacy across shared workstations or for remote teams who alternate between private tasks and collaborative reviews with colleagues or clients.

When you choose PF340W2B, you’re choosing a trusted privacy solution from a brand with decades of optical filter expertise. It’s optimized for 34" ultrawide displays, aligning with the physical dimensions of most popular 34-inch monitors. The result is a clean, edge-to-edge privacy experience that doesn’t distort the image you rely on for precision work. As data protection requirements continue to shape modern workplaces, this 3M privacy filter serves as a practical, cost-effective measure to help prevent inadvertent data exposure while supporting a productive, comfortable viewing experience. Whether you’re working from home, in a busy office, or traveling with a docked workstation, PF340W2B helps you maintain focus and privacy without sacrificing performance.
