This extensions contain the video card information string and monitor information strings that show the resolution and scan rate for the attached monitor. The IIsi Monitors Extension also contains the options for setting the maximum number of colors that can be displayed since these machines used RAM for the video. If you remove this file, your computer can still use the video card and you can still select the number of colors displayed on your monitor, but monitor options (such as gamma settings) may not be available. Unnecessary if you are not using Macintosh IIsi.
