3M (PF400XL) for 16-19 in.

Designed to protect your privacy, the PF400XL Privacy Filter from 3M™ fits a range of 16" to 19" CRT and 17" to 18" LCD monitors. This filter allows the persons directly in front of the monitor to see the on-screen data while a passerby views only a blank, dark screen. Using its microlouver privacy technology, this filter keeps your on-screen data private without blurring or distorting screen images. It significantly reduces glare to prevent eyestrain and headaches related to continuous monitor viewing. In addition, the filter blocks ELF/VLF E-field radiation and prevents static and dust build-up when properly grounded. The package includes two sets of hanger arms for CRT and LCD desktop monitors to meet most users' preferences. With its flat-framed design, this easy-to-clean privacy filter is an ideal choice for high traffic areas and open plan cubicles. The monitor shown in the image is sold separately.
