My first response was ¯\_(ツ)_/¯ -- but I dug some more and found out that P2 is a Blue-Green color used in oscilloscopes, but it doesn't look like monochrome computer monitors were ever made for it though [1].

- duskwuff 5y agoP2 was a long persistence phosphor. It was used in analog oscilloscopes because those couldn't be refreshed -- the waveform was drawn onto the display as it was received, and the phosphor was responsible for making that visible. You wouldn't want that in a computer monitor. The computer is perfectly capable of refreshing the monitor, and the long duration of the phosphor would make anything rapidly changing (like a scrolling display) impossible to read because all of the previous contents would interfere with the current image.
- kevin_thibedeau 5y agoStorage tube monitors did use long persistence phosphors. They were a way to simplify the refresh and memory requirements on early hardware.
