34-inch 21:9 privacy filter for flat monitors

The 3M PF340W2E is a black privacy filter built for 34-inch widescreen displays with a 21:9 aspect ratio. It uses microlouver technology to darken the screen for anyone viewing from outside a 60-degree angle, keeping on-screen data visible only to the person sitting directly in front. The filter is reversible, offering a choice between a glossy side and a glare-reducing matte side. It suits professionals who handle confidential information in open-plan offices or public spaces.

60-degree viewing limit and adhesive attachment

Privacy is effective only within a 60-degree viewing cone; viewers beyond that angle see a darkened screen. The filter reduces blue light transmission by 35 percent and cuts reflections for clearer image clarity. It attaches with clear adhesive strips designed to stay on the monitor, so the filter cannot be quickly removed and reapplied like magnetic or tab-mounted alternatives. The surface resists scratches, fingerprints and dust, and withstands hundreds of cleanings.

Check for flat glass screen and curved compatibility

Confirm that your 34-inch monitor has a flat glass front; the adhesive strips require a smooth, uninterrupted surface to bond securely. The product notes compatibility with curved displays, but the adhesive method works best on flat panels. Ensure the active display area matches the 21:9 format so the filter covers the full screen without overhang. Buyers who need a removable or frameless mounting option should consider a different attachment style.
