The 3M COMPLY Magnetic Attach system enables rapid switching between superior privacy and screen sharing via ultra-powerful magnets that firmly secure the frameless filter. Utilizing rare earth magnets 100x stronger than standard fridge magnets, this innovative design attaches smoothly to your 23" monitor for a sharp, clear view. It provides robust "blackout" privacy beyond a 60-degree angle and cuts blue light without altering display colors. This widescreen filter flips between a glossy finish and a glare-reducing matte side; the matte texture minimizes reflections and smudges. Built to last, it endures numerous cleanings. Designed in landscape orientation with dimensions of 20.38" x 11.45" (518mm x 291mm).
