Display Device Selection in BIOS?

I have been trying to fix a problem I am having with my i8500 display settings, and am wondering if it is a hidden BIOS setting.  For background info on the problem, please see my posts in the Video forum:

I have 5 or 6 posts on the first 2 pages.  You will see on the secong page that I posted information on this setting being available in the PHOENIX BIOS (older DELL BIOS), but not in the newer DELL BIOS.

I have upgraded my BIOS to A05, and that did not fix the problem.  When upgrading the BIOS, does it keep your setting, or reset them?  I am assuming it is keeping your settings.  So, if I reset my BIOS to default settings, will this do it:

Anyone have any other ideas about this?

Any help would be greatly appreciated.
