Macintosh Monochrome Display

Overview

The Macintosh Monochrome Display was Apple's second 640 x 480 grayscale display for the Macintosh. It was introduced with the Mac IIsi and Mac LC in October 1990 and uses a 12" grayscale CRT. This display is lighter, draws less power, and has a more modern look than the Hi-Resolution Monochrome Monitor it replaced. It has a fixed resolution of 640 x 480 and uses Apple's DB-15 video connector (not to be confused with the smaller, higher density DE-15 VGA video connector).

The power button is on the back of the monitor; the brightness and contrast controls are on the right side. The monitor can sit on top of most desktop Macs. Apple also sold a tilt-swivel base for this monitor.

Apple recommends using a screen saver to avoid phosphor burn caused by static elements on the screen, such as the menu bar, drive icon, and Trash. To clean the screen, Apple suggests applying household glass cleaner to a clean cloth or paper towel and wiping the screen. You should avoid spraying glass cleaner directly on the CRT, as it could run down the screen, into the case, and damage the internal electrical circuitry.
