Re: Use of Powerpoint with NEC LT220 projector


Good stuff. That brings up another question for you, Peter.
When you mentioned that everything looks ok when you play a DVD, I

If you meant that the projector does a good job when fed from a DVD player, not
the PC ... very different story. In that case, ignore my suggestions until
you've tried Bill's, 'kay?
