This Anti-Glare Filter from 3M is designed to mute the glare that glossy monitor screens can produce. The medium tint glass diffuses light on screens where indoor lighting conditions produce glare or distracting light while still providing improved colour representation than darker filters can produce. This filter is designed for use with older model 17"-18" diagonal monitors. The outer dimensions are 15.5" W x 12.75" H while the filter glass is 14" W x 11.5" H. The filter is suspended in front of the monitor screen by two tabs that fold out to sit on top of the monitor. The tabs offer about 1.5" of height adjustment to compensate for a wider bezel at the top of the monitor. |
