Also that CRT was probably 21" max, and weighed 20% of the human looking at it.

You are way too optimistic about the weight. ViewSonic p225f with 20" visible display, that reportedly was capable of 2560x1920/63Hz weighted 30.5 kgs!

I am not sure with that dot pitch of 0.25mm it was worth it.

If anything - you can get it waaay cheaper now.

I'm struggling to remember how much they did cost, but with $2000 price tag for the top of the notch machine the monitors on the low end tended (well, AFAIR, don't take my word for it) to be less than $150, and hi-end were like $700 for not the ultra-uber-special cases.

Not at all! Your common as milk Philips and ViewSonic 19-21” could do that easily!
