Framed privacy filter works in your 27" 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. For collaboration and sharing the screen, this robust, framed privacy filter is easily removed. Wide-screen filter reduces 35 percent of blue light transmission from the display and helps reduce reflections so you see your screen clearly with pristine image clarity. Scratch-resistant privacy filter with 16:9 aspect ratio attaches in two ways: hanger arms or Command Strips. Viewing dimensions are 24-3/16" x 13-7/8" (614mm x 353mm).
