Anti-Glare Filter reduces glare and mirrorlike reflections, making your screen easier to use in high-glare situations. It can also protect your screen against scratches. Use filter on 19" wide-screen desktop LCD monitors with a diagonally measured, 18-15/16" viewing screen and a 16:10 aspect ratio. Actual filter dimensions are 16-1/16" wide x 10-1/16" high (408mm x 255mm). Lightweight, thin, frameless design is easily applied and reapplied numerous times with no bubbles. It attaches with optically clear adhesive strips. Easy-to-clean filter is compatible with most touch-screen displays and includes a cleaning cloth.
