The professional series of monitors, from NEC, all had complete controls for adjusting every aspect of the image. Noir, it sounds like your monitor was not properly calibrated. Quite frankly, the Sun monitors were decent monitors, but they were not professional grade monitors.
I have run into very few (only one other person I know) who used a professional grade CRT. They were very expensive. About 5 to 6 times the cost of a decent quality consumer CRT of comparable size (mine came in at just under two grand).
My monitor still has the best black levels and clarity of any monitor I have ever used, to date. I get it calibrated once a year and it is still within 98% color accuracy (most LCD panels struggle to hit 75% accuracy). When people first see I have this old CRT, they chuckle and make some comment about the dinosaurs. Then I turn it on and jaws drop. It sits a few feet from my Wifes panel and everyone agrees the image quality is better on mine.
Honestly, most people have it better off with an LCD panel when they are coming from the typical consumer grade CRT monitors as most of those monitors were abysmal. None of them, including the professional series, were set with the correct color temperature from the factory. Thus none of them could reproduce accurate color. If you had a consumer grade monitor which had a color temp setting, it was usually a preset of some sort, which was better than the factory setting, but still a long way off from being able to be calibrated correctly.
If my monitor blew out tomorrow, I would be ok with the monitor my Wife got. It is not perfect and the smearing is insane, but I value color reproduction above all else so I would live with that trade-off and just learn to close my eyes when scrolling anything on it.
