I am thinking of getting a front projector to replace my RPTV but I have some questions. What is the best way to get the video signal to the back of the room (approx 22 ft.)? I can't move the gear. I want to switch everything through my AVR if possible. Do/can I get a long component cable? What about composite/s-vid sources ([email protected] changer), do I need to convert them to component (scaler or Denon AVR)so I only need one cable. What about DVI or other options? When I read about screen size are those numbers the diagonal? Do you effectively get a better picture if you don't "blow" up the screen size as much? Are DLP projectors DIY mountable? If not, what is a ballpark figure by a pro? Thanks for any help.
