Re-visit the past with a new “old monitor nostalgia” mode for your expensive high-resolution television or computer display!

The issue:

Modern computers (and TVs) have large, high-resolution screens.

But sometimes people have nostalgia for the past—perhaps yearning for Cold War-era computing, when the harsh glow of a 9-inch CRT monitor represented the pinnacle of technology (Figure 1).

Fig. 1: This 1984 black-and-white Macintosh cost approximately $5500 in 2019 dollars, which will buy approximately 10 economy-priced laptops in the year 2019.


Modern monitors should have an option to emulate the behavior of various old display types.

For example, a high-resolution monitor could easily pretend to be the following:

  • A 1950s tube television
  • The tiny black-and-white screen of the 1984 Macintosh (Figure 2)
  • The monochromatic green display of the Apple //  (Figure 3)


Fig. 2: In “Mac ’84 mode,” only a tiny fraction of the screen is used (left), in order to give the user that authentic 9-inch-screen experience. (The blue area represents an unusable border region.)

Now that a “Dark Mode” theme has been implemented by nearly every operating system vendor, the next arms race is sure to be “retro display mode” or “retro CRT filter” mode.

PROS: Gives people a greater appreciation of modern technology.

CONS: May cause eyestrain.
