I just received my 60X80 curved screen and after a little work got it hung on the wall. The picture is very bright and perfect for the room where we have the projector. However the mounting is very difficult since I am mounting it into a recessed section of my unit and I need to do a blind mounting of the screen has anyone done this I am looking for any suggestions. Also where do you measure the distance from the projector for the proper picture size since the screen is curved. The last question I have is for those who already have this screen the surfase has bumps on it and the bottom middle section has a half mooned ripple on it is this normal?
