With 30 percent more clarity than standard 3M Black Privacy Filters, this High Clarity Privacy Filter works in your 23.8" wide-screen monitor to help protect your screen from everyday scratches and dust, and help keep the information displayed on them private. Advanced Microlouver technology delivers effective "black out" privacy from side views outside the 60-degree viewing angle. You get crisp image clarity on your display while visual hackers with side views are kept in the dark. Filter reduces 35 percent of blue light transmission from the display. Glossy finish on both sides provides enhanced clarity. Scratch-resistant, frameless privacy filter with 16:9 aspect ratio easily attaches with attachment strips or slide-mount tabs. It is also easy remove and clean. Viewing dimensions are 20-2/3" x 11-2/3" (527mm x 296mm).With 30 percent more clarity than standard 3M Black Privacy Filters, this High Clarity Privacy Filter works in your 23.8" wide-screen monitor to help protect your screen from everyday scratches and dust, and help keep the information displayed on them private.
