However, I am not a fan of 'super' quality. I think some of the CRT are acceptable, and of course, the back-projection tv are fantastic 'enough' in terms of quality. What I need is size. 1) Regarding the specs, are there anything that I should be concerned with (light spills, lumin, distortion, etc) ? 2) I have a yellowish wall that I plan on projecting it to. Is it necessary to have it white in color? If yes, is a projector screen going to make a difference? Are there any other alternatives that are more affordable (sheet of cloth, fabric, formica, etc)? Thank you in advance.
