I currently have a 77 inch screen for my panny ptl200u projector, and I want to possibly go bigger. I am looking at something like 96-100 inches since I'll be sitting with my eyes about 140-145 inches away. What is the cheapest way to do something like this with GOOD results??? I currently have a plain jane model b dalite screen, and I was wondering what a good DIY alternative might be. Would just my walls be feasible--I've looked at the image projected on the wall and it's not terrible since the walls are a beige color. I visit AVS forums once in a while but a lot of that stuff seems too complicated for a novice like me to build. I hear a lot about blackout material...what about making an entire screen out of that? I am a newbie when it comes to building a screen like this, please understand. That plus honestly I'm not TOO handy at all--but could get the help of many who are if need be. Thanks for any and all help.
