The xorg.conf there doesn't define HorizSync or VertRefresh. He mentions a video BIOS patch called '915resolution'. There's a
FreeBSD version at: http://www.freebsd.org/cgi/url.cgi?ports/sysutils/915resolution/pkg-descr More information on "the hack" here: http://www.geocities.com/stomljen/
I'm already using this. It's listed at the end of my email. In case my message was unclear, I've already managed to get the native resolution. I'm only looking for the proper HorizSync / VertRefresh rates, to avoid frying my graphics card or screen, and to get the maximum out of my hardware at the same time. I've already tried rates from several articles, but all of them result in warnings that the rates are outside the DDC spec, and none of them document where the numbers are from. The only reference I've found so far, MonitorsDB, is wrong, and Dell doesn't list the information I need. -- Victor Engmark Quidquid latine dictum sit, altum videtur - What is said in Latin, sounds profound _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
