3M PF340W2B Privacy Filter 34" 21:9 60° Viewing

34-Inch 21:9 Privacy Filter

The 3M PF340W2B is a display privacy filter built for a 34-inch widescreen monitor with a 21:9 aspect ratio. It uses micro-louver technology to narrow the viewing angle so that on-screen content is visible only to the person directly in front of the screen. The frameless design delivers a 60-degree viewing angle for the primary user while blocking side views. A reversible glossy or matte surface finish adds flexibility for different lighting conditions.

Suited for Open-Plan and Shared Spaces

This filter suits professionals handling confidential data in offices, coworking areas or public environments where visual privacy is required. The anti-glare matte side reduces reflections and hides fingerprints, while the glossy side preserves screen vibrancy when glare is not an issue. Buyers needing a filter for a different screen size, aspect ratio or a curved display should look at alternative models that match those exact dimensions.

Consistent Privacy Under Continuous Use

The scratch-resistant surface maintains optical clarity during daily cleaning and long-term deployment. Micro-louver performance does not degrade with extended screen-on time, so the 60-degree privacy zone remains effective throughout the workday. The reversible coating allows the user to switch between glare reduction and maximum brightness without removing the filter, supporting sustained productivity in changing light.
