do CRT's get more blurry at higher res/hz?

[dpopiz]

it seems like CRT's are always more blurry at 1280x1024x100hz compared to 1024x768x60hz
maybe because it's sorta at the upper limit of the video bandwidth?
or am I just imagining it?

No you are correct. Resolution eats up bandwidth and so does refresh rates. When you up the refresh rate too high, the image gets blurry because the monitor has less bandwidth to work with.

must be a cheap video card or monitor. i was running 1920 x 1440 and it was clear as hell, just small as hell too

I'm pretty sure it's not a bandwidth issue. It's most likely just an issue of that specific monitor or video card, more likely the monitor.

My 19" monitor is crystal clear at 1024x768, but starts to get slightly blurry at 1280x1024, and is unusable for long periods of time at 1600x1200. Some monitors can do 1600x1200 fine on vga, though.

It can actually be the strength of the signal. A good cable gives far better quality than a crappy one. A relatively short cable also gives better quality than an extended one.

It's a GPU problem, not a monitor problem.

Could be the video card ,monitor or even the refresh rate,I`ve seen some monitors look sharper at 85Hz then 100Hz with my own eyes,all you can do is start ruling out possiblities like try a better video card( like a Matrox video card) better quality VGA cable,different refresh rate ,and if you are still not happy then a better monitor .

Is there any video card with a RAMDAC greater than 400MHz?

I am not an expert but I cannot see any noticeable difference or blur at 10x7(100Hz) or 12x10(85Hz). I have a Nokia 447 xpro and a gigabyte 9800pro
Both resolutions work just fine for me, and I am completely satisfied with my monitor.
I think no matter the size of each monitor, quality is an essential factor. After all most of the times you get what you pay.

my 22" NEC looks awesome @ 1600x1280 @ 85hz...won't play at anything less and yes, I am pimp
