Hi! i dont know this is the right subforum. And sorry my english

I have a nvidia 9800GT, XP SP3

Sadly there is a 640x400 60hz resolution, that i can not remove. Is not in nvidia inf, not anywhere in register... maybe is builtin in windows?

I want to REMOVE, because i need to replace with 640x400 70hz

Sadly SDL programs like dosbox or PCem cant automatic change HZ, then always use 640x400x60hz

Thanks a lot for any ideas
