Hi Tony!

This is a guess.  I think that the boot process talks to X but also to
Gnome.  So, if the monitor is unknown, both X and Gnome go to the crude
resolution in hopes that we will see something.

Try going to System > Preferences > Screen Resolution -- see what you have
in the drop down menus -- hopefully, choose what you want, and then if it
works make it the default.

Good hunting!
