What are the old , fat monitors called?

Early digital monitors are sometimes known as TTLs because the voltages on the red, green, and blue inputs are compatible with TTL logic chips. Later digital monitors support LVDS , or TMDS protocols.Green and amber phosphors were used on most monochrome displays in the 1970s and 1980s. White was uncommon because it wasmore expensive to manufacture, although Apple used it on the Lisa and early Macintoshes.
