3M Privacy Filter Black, Matte

Custom-cut privacy filter works in your 21.5" Apple Mac 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. 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. Reversible design includes a glossy side and a glare-reducing matte side that helps hide fingerprints. The frameless, scratch-resistant privacy filter with 16:9 aspect ratio is easy to attach, remove and clean. Two attachment methods are attachment strips and slide-mount tabs. Viewing dimensions are 20-3/4" x 12-9/16" (527mm x 319mm).
