Final resolution was to edit the Video Mode Settings and define two seperate
HD resolutions.
one 1760x960 and one 1920x1080

1760x960 is used for the menus and 1920x1080 is used for Video Output.  This
work fairly well but do give some extra delay when switching between menus
and TV output, you see the bottom of the "Desktop" when switching to the
Program guide from live TV.  This is a minor issue.  However when you reboot
or cold start the system, the first time in resizes the menus it scales them
to the 1920x1080 screen size.

You have to go through Utilities/Setup Setup / Appearance  and the just OK
through all the screens and it them resizes them for the 1760x960
resolution.

Thanks for all the assistance .....
