3M HC215W9B High Clarity Privacy Filter 21.5" Widescreen Monitor Accessory

3M High Clarity Privacy Filter 21.5 Inch Widescreen

This 3M High Clarity Privacy Filter is designed for 21.5 inch widescreen monitors. It uses microlouver technology to darken side views outside a 60-degree viewing angle while preserving a crisp, glossy image for the user. The filter measures 18 3/4 by 10 9/16 inches and includes attachment strips and slide mount tabs for installation. It offers on average 30 percent more clarity than standard 3M Black Privacy filters.

Suits open-plan offices

The glossy finish maintains screen clarity for direct viewing, making it suitable for professionals handling confidential data in public or collaborative areas. Users who prefer a matte anti-glare surface or require a filter for a different screen size or aspect ratio should look at other options. This model is specific to 21.5 inch widescreen displays and will not fit standard 4:3 formats or other diagonal measurements.

21.5 inch widescreen compatibility

The single specification that decides fit is the 21.5 inch widescreen diagonal measurement of the viewable area only. Buyers must measure their screen diagonally from corner to corner excluding the bezel to confirm compatibility. The effective privacy zone is limited to a 60-degree viewing angle, so side visibility is restricted outside this range.
