I'm looking into getting a projector sometime this year and I am doing some preliminary research. I hope you can help me with a few questions I have. 1. If I was to go for a CRT projector, how far do they need to be from the screen to produce a 7 or 8 foot diagonal? 2. Can you use a CRT projector with a 16:9 screen? Wouldn't a 4:3 image appear outside of the screen boundary? 3. How do LCD and CRT projectors compare when used in ambient light? Obviously I would view DVDs in darkness, but what if I want to watch Sky digital? Any help on these matters would be much appreciated.
