Hi,
Yeah. I finally got it working very much in the same way you did it. What you've
mentioned is exactly what happenned to me too. I referred to my monitor manuals
and gathered info on the web and finally succeeded in having the right modes for
my monitor after manually deleting all of the ones that didn't exceed my
monitors refresh rates.
Thanks.
Regards,
