""which crt monitor""
you will be better off if you will take a look at them, the one that you will like the most is yours to take, caz in reality 19 inch can produce more than the 21, and the most impartant thing is eye strain, find the one that is calm to look at, not too flashy or bright and has no "visual" vibration of the image (if you'll look calmly and curiously you will notice that even it is "stable" it still reflects some frequency hard to notice on "quick hand")
example: I worked with 5 PCs on my desk at a time, and there were 17 inch ViewSonics ones that I was working on all the time, ignoring 19 NECs and 21 Sonys like a plaque, caz they were giving me eye/head pain, even they "looked" better.
like right now I am working with 15 inch LCD on Thinkpad on the road and Dell 17 inch at home and after a day of "looking" at LCD my eyes are becoming "blorry" (stuff like lights on the road kind of spreads/dowbles), with CRT I have no such problem even after working day and playing UT whole night. even LCD's text "looks" better.
..this is very useful and helpful place for information...
