It has both, which complicates things. Perhaps if you disabled the
NVidia card in the BIOS, something would work?  I'm only guessing; I
don't have any machines more modern than a T61.

It's also a question of how the outputs are connected to the graphics
adapters; e.g. it's possible that DisplayPort is only driven by the
NVidia chip.

Why not?  My Asus EeePC 900 (ancient Intel 945) drives a 1920x1080p TV
over VGA with sufficient 3D for all those Compiz effects.

Digital video would be much nicer, though.  The pixels would align, and
you would avoid analog noise.

Well, there's a quantum computer that can factor 15, so those of you using
4-bit RSA should worry.
