CRT image sharpness @ high Hz

[keyser]

I finally upgraded my ADI 17" CRT (had it since 1998) and got a Lacie 22" CRT! It's great for gaming and general use. Playing around with it I notice that the sharpness of the image really gets worse after 90Hz (120 is worst). Testing at a low 60-75Hz and ignoring the insane flicker comfirmed this, displaying a sharper image.

I was wondering could this be a DVI to VGA converter thing or is it just a VGA/CRT thing? The DVI-VGA dongle I got with my Gainward Geforce 4 card was awful compared to the one I use now, that came with my Leadtek 7800GT. Would a better quality DVI to VGA converter or VGA cable improve things (if they exist)?

I'm using 1400x1050 for desktop btw @ 90Hz, coz I see a slight flicker @ 85Hz

Thanks in advance.

How would I avoid using an adaptor? Your adaptor must be pretty good then? Got a spare? I might look out for some on the net and buy a few different ones, see if they make much difference, failing that change VGA cable. I also had a crazy idea of buying 'top of the range' PCI VGA card and switch between the 2 inputs on monitor! That may be going too far plus I don't know how XP would get on with 2 gfx cards.

BNC, bah this one doesn't have any! my old monitor did, typical

thanks for info

EDIT: DVI 24+ 5 plug to 15 pin High Density VGA plug 1.5m cable £24 - how about something like that, or is it a bit pricey? (I don't mind, if it works)
