Under pure dos, I don't care much about under win but it doesn't work too.

Yes I had GF4MX440 before and it worked fine. As I wrote it's issue of GF5xxx and newer.

I tried many programs but all rely on VESA 3.0 standard of setting CRTC by calculated GTF. Simply nVidiots screwed it up in BIOS so ANY VESA program will not work. This must be enforced via setting some vendor specific registers in nVchip (far beyond VESA standrard) which are not probably documented.

BTW I read on some forum that ATI VGA BIOS can be modified by bios editor to override default refresh rates. ATI, as I know, provide only VESA 2.0 but now with this feature it is better than nVidia VESA 3.0 (but I don't know what else bugs may ATI VESA BIOS have).
