Tektronix built a lot of test equipment based on color-shutter CRTs in the 1990s. It was simultaneously nifty and awful. They could render rich, well-defined color waveforms, but as soon as you moved your eyes, the illusion would break apart into rainbow-colored fragments. It was like watching a movie on a DLP projector, only much worse.

Meanwhile, HP OEM'ed a bunch of Trinitron monitors from Sony and called it a day.
