The 3M PF240W9B Privacy Screen Filter in Black is a durable and effective solution for adding an extra layer of protection to your 24-inch monitor. It features a glossy surface that helps reduce glare and hide fingerprints, while the anti-scratch matte surface helps reduce blue light and maintain the natural color of your display. Designed to withstand hundreds of cleanings, this privacy filter is easy to attach, remove, and clean, and is compatible with most touchscreen displays. It also provides effective "black out" privacy from side views outside the 60-degree viewing angle, making it an ideal choice for those looking to enhance their screen's privacy and protection.
