Green phosphor coating was cheaper and had a longer "glow" time so it worked better on lower refresh rate equipment. Why they weren't all white later, once that all mattered less, is a good question. I do know that HP charged us more for the white ones...that never changed.
- daveslash 5y agoI wonder..."once that all mattered less".... I wonder if, by the time that white CRTs were cheap enough, if color CRTs were also cheap enough (albeit, more expensive than white monochrome), that most consumers just said "f-it, for an extra X, I can have full color instead of _just_ white?"
- tyingq 5y agoI'm sure that was true for PCs, but for dumb terminals, there weren't that many that supported anything other than monochrome.
