The text sharpness with CRTs is something that seems to vary a lot with individual units. The three duds I went through earlier all left a lot to be desired, as the monitors were not only blurry but the blurriness was inconsistent across the screen, but my current one looks extremely close to an LCD in this respect after I adjusted the focus and everything, much better than any other CRT I have seen. I have to put my head up close to the screen to tell the difference at most resolutions. It falls off a bit at 2048x1536, but still is quite good even there.
Some things about CRTs drive me nuts. I used an LCD only for 2 whole monthes while I was away from my personal desktop. When I came back to the CRT it seemed extremely blurry as far as text sharpness goes.
Another thing is the imperfect geometry. I did not get a perfect CRT. I am limited to a few resolutions at specific refresh rates if I want good geometry. For example, I cannot use any of the 1280x960 options because of geometry problems. I spent monthes with Powerstrip adjusting the front and back porches, and I've scored a good rate on every other res besides 1280x960.
But I forget all of it when I play games or movies with my superbright 1 setting. It cranks up the contrast and brightness.... colors become insane... blacks actually get more black, making dark spots scarier, but at the same time light sources get brighter - it creates a bigger spectrum for a whole new atmosphere in games. Text is unreadable in this mode, but the colors come alive.
Yeah, that's the sort of crap you have put up with when buying any good CRTs these days, and it's not just limited to the used and refurb ones; the manufacturing quality simply went to hell shortly before they were discontinued altogether.
Regarding the geometry issue, are you talking about the vertical linearity distortion at the top? I got that with one of my defective units, although the one I have now has no such issue.
The superbright mode is awesome though. After getting to used it for eight months, games now look quite ugly without it. It doesn't seem to affect the text much (in terms of blurriness) despite what I've heard about it, although I prefer a dimmer look for text viewing anyway.
