Gold Privacy Filter keeps confidential information private when working in public places. It is great for high-traffic areas such as airports, airplanes, commuter trains, coffee shops and other public places. You see your laptop screen with incredibly crisp image clarity while visual hackers with side views outside the 60-degree viewing angle see a vivid golden shield. Proprietary gold effect provides premium privacy with a glossy finish. Filter reduces 35 percent of blue light transmission from the display. It is reversible between vibrant gold and a glossy black screen. Filter is designed to fit wide-screen monitors with a diagonally measured, 23.8" viewing screen and a 16:9 aspect ratio. Actual filter dimensions are 20-2/3" wide x 11-2/3" high (527mm x 296mm). It includes your choice of two easy-to-use attachment methods. Lightweight, thin, frameless design protects display from dirt, debris and scratches. It cleans easily with a soft cloth and water.
