it can get worst than that. In a few cases (mostly Compaq), if you
don't have the projector connected before you turn the notebook
on, you don't even get the text boot sequence to show. Using the
function keys on the keyboard you get the feeling that the SVGA
port is being activated (the LCD screen blanks etc etc), but you
still get no image.

So, as a rule of thumb, I always try to connect the projector
before powering the notebook.
