I just discovered that PPT dual-screen mode (presenter view on built-in screen, slides on projector/external monitor) suddenly doesn't work on my X1 with W7 using Office 2010. This is a recent change and I'm guessing due to a driver update from Microsoft or other source. I've googled and tested solutions that others have found on other brands, i e disable hardware acceleration in PPT settings, uppdate display driver (I did from Lenovo's drivers section) and no difference) so am now at a loss. Seems to be something brand-specific so I'm hoping for Lenovo gurus to point me in the right direction.
