Try pressing down Fn+F7 ( I am not sure if it was F7 but the key
combination
to switch to external CRT ) and if this gives you proper screen, and if
you are
happy with it, this is the answer.
If you are not happy with Fn+F7 solution, there is a patch avairable to
fix this
problem. I cant remember the URL but if you could wait, I will get if for
you.
bye for now...
