So, before I buy or build a screen (don't know if I can DIY since I need an acoustically transparent screen), do most of you think it is best to get a projector and just use the painted wall before deciding on a final screen size and AR? If so, my question, which is definitely of the "which came first" variety, is if I do not have a screen, can I accurately and fairly demo various projectors before I purchase? This also assumes I can actually find somewhere that will let me demo before I buy.
Thanks!
Thanks!
