To cut costs we have decided to make our on fixed screen. We will buy screen fabric like what we already have for out portable screen and build a border around it to make it more permanent. I was also thinking since the wall is already a dull (non glossy" white, what would it hurt to just shine on the wall??
Simply projecting on a painted wall can work pretty well if the wall is a light, neutral color and doesn't have a lot of room light falling on it.
Out back-wall display for cuing the people on the platform is just a section of a cinder block wall that was painted a light brown many years before. We put a maybe 20 foot diagonal picture on it with a 1500 lumen ceiling-mounted Canon XGA projector. It's in an area that is shaded from window light sources and is very acceptable. The texture of the wall is not noticeable given that it can't be seen from the main floor from less than about 60 feet away.
Screens made of specially-formulated regular interior house paint on smooth surfaces such as finished drywall are favored by many videophiles. If you search google you can find recommendations for formulating specific brands of paint at your local home improvement store, along with photographs of actual installations in use.
There are also paints that are specially formulated for the specific purpose. There is a controversy over whether they are worth the extra money.
