But with a large enough CRT of a given dot pitch, you can start to notice blurring at the highest combination of refresh and resolution. Backing off helps the sharpness a great deal.
I know what you are talking about. CRTs do blur with higher refresh rates, it's a phenomenon occuring in the phosphor. 75Hz is much sharper than 85Hz, but i can't stand the flickering.
For now, i settled for 1280x1024 @ 85Hz because:
1) I'm still running XP on this computer (and forever will be since it's an older machine) and XP uses fonts of size 8, it gets kinda hard to read anything smaller
2) It gets this stupid geometry issue on higher refresh rates - the bottom right corner toes in a bit, and it is unfixable
3) This monitor has a 5:4 aspect ratio (ie it is taller
than your average monitor, so 1280x1024 is the optimal resolution, a 4:3 AR would look horizontally stretched on it
4) The convergence issues are still bothering me a bit. Hasn't had enough tweaking i guess.

1600x1200 on a 17" will kill your eyes indeed. However, if you are running Vista, you will find 1440x1080 to be perfect for a 19 inch. The larger text and icons make for a perfect high-res experience. (1440x1080 is the actual correct res for a 4:3 monitor, you will have to custom define it).
Anyway, that TV wasn't old (it's about 4 years old and has got a flat screen), but it was standard def. Actually, this monitor is 7 years old (fabrication date April 2002).
Anyway, things i've noticed on this monitor (FYI it's the IBM P275
, but i think you knew that already):
It is HUGE and DAMN HEAVY.
It has a small scratch in the anti-glare coating on the right side. Not enough to be annoying but enough to be noticeable. I have not decided yet if i want to remove the coating.
It takes FOREVER to warm up. Right now i just came from outside (i had just calibrated the monitor before i left), and i can see that the focus is a bit off again, and that it's brighter than i left it. Slowly the brightness and focus are going down to a normal level.
I have not noticed any hardware convergence controls (ie physically on top of the tube), which is a bit of a surprise. Also the flyback only has two focus knobs (that i made good use of), there is no G2 voltage adjustment knob. Now i understand the idea of that resistor mod. FYI, in place of that resistor should have been the focus knob. There are two coils with adjustment cogs on the side of the tube, i haven't messed around with those.
The convergence controls on the menu are comprehensive, but lack a "balance" function so i can't really set it up right. When i converge a tube, the first thing i do is mess it up the worse i can (applies to vertical convergence only, as that has the most issues). I split the R, G and B lines as far apart as they go. Then using the top and bottom knobs i adjust the error to be the same on the top and bottom, then turn the balancing knob back and the lines will align like magic, combining into one solid white line. Unfortunately i wasn't able to do the same on this one. Nothing beats analog controls...
(EDIT: I just noticed the one i was talking about, it was the "normal" vertical convergence setting. Silly me. There is a tendency of bowing up in the red at the top so the line isn't totally gone, but now it's enough to be hardly noticeable.)
The vertical convergence errors are most noticeable at the top of the image. I can't seem to get that right without messing up everything else. Horizontal convergence is okay, not perfect but close enough.
The contrast does not go as low as i'd like. At night, i like my monitor very dim. Because of the high brilliance of the Trinitron tube, this is not achievable. It does however have a very pleasant picture when the contrast is turned to zero, with no color hue.
The picture is a bit "jittery". I'm sure it's not the cable as it happens in the OSD too, as a matter of fact it is the most jittery when the OSD is displayed. It is not noticeable under normal viewing conditions though. I assume it's the moire correction doing that, i've seen this on other monitors as well, and my Nokia does it too. It doesn't bug me.
The "Color Return" functions did WONDERS. I mean, really.
A few pics of the inside. By the amount of dust, this thing has never been serviced. That's good.
Sony Trinitron, made in Japan.
After a bit of a cleanup.
What it's replacing. The small monitor on the left i found in the dumpster, it's a 15", it has a crappy picture, but it was alright for IM'ing when i was watching TV.
The calibrator's companion.
The setup now.
And finally a photo of how some text looks on it. Not bad, not bad. There is room for improvement though - check the bad convergence at the top.
