I have similiar problem. But when I tried to install lion on external hard disk. after installation display screen was inverted. Did you solve your problem?

Have you looked into the Accessibility pane in System Preferences? That's where you usually go to invert colors, etc. - maybe the update just did it for you, unintentionally.

Yes I looked into it and it was black on white!
