In the ever-evolving world of technology, it’s fascinating to look back at the products that shaped our digital landscape. On March 7, 1989, Apple introduced a remarkable addition to its Monitor series: the Apple High-Resolution Monochrome Monitor.

This 12-inch grayscale display was tailor-made for the Macintosh IIcx, offering Mac users a high-resolution monochrome experience at a time when color displays were gaining popularity. Although its existence was short-lived, the Apple High-Resolution Monochrome Monitor holds a special place in tech history, reminding us of the early days of Apple’s innovation and design prowess.

When the Apple High-Resolution Monochrome Monitor hit the market, it instantly stood out as a unique offering from the tech giant. It was Apple’s inaugural foray into the world of 640 x 480 grayscale displays for the Macintosh platform. With its fixed resolution and the use of Apple’s proprietary DA-15 video connector, this display set itself apart from the growing number of PCs adopting the smaller, higher-density DE-15 VGA video connector.

The Apple High-Resolution Monochrome Monitor boasted an understated yet elegant design. The power button discreetly graced the back of the monitor, while the brightness and contrast controls were conveniently placed on the right side. Designed to sit atop most desktop Macs, Apple also offered an optional tilt-swivel base for users seeking an adjustable viewing experience.

Apple provided users with helpful guidelines to ensure the longevity of their Apple High-Resolution Monochrome Monitors. To prevent phosphor burn caused by static screen elements, such as the menu bar, drive icon, and Trash, Apple recommended the use of screen savers.

Cleaning the screen was a straightforward process, involving the application of household glass cleaner to a clean cloth or paper towel. However, caution was advised not to spray the cleaner directly onto the CRT, as it could potentially damage the internal electrical circuitry.

Although the Apple High-Resolution Monochrome Monitor may have had a short lifespan, it left a lasting impression on those fortunate enough to experience it. Priced at $898 during its release, it was considered a high-end option for Mac users at the time. However, on February 11, 1991, Apple made the difficult decision to discontinue the monitor, making it a rarity and collector’s item today.
