Odd that they spend so much time talking about alignment, because all of my trinitron based CRT monitors over 20" needed to be adjusted seemingly on a daily basis to converge correctly across the whole screen. This was something that I rarely remember doing with the cheap shadow mask monitors (although frankly they were generally smaller screens) and at a lower resolution.
The trinitron monitors I had were running 1600x1200 or better and with a small font the convergence would give white text a purple shadow/etc. Very 1980's apple ][, which a lot of people seemed to be OK with, or maybe its just because they ran much lower resolution TV signals or much larger fonts.
Are they flat screens? Flat as in the glass is not curved of course, not flat as in thin. The flat ones are well known for developing a whole host of convergence/geometry issues that the curved ones either don’t, or take much longer to manifest.
Yah, by the mid/late 1990's when I had a pile of them at work/etc they were mostly "flat" screens because that was sort of the default for a midrange+ monitor in that timeframe.
