Just bought our first projector, it will be here Monday. We have been trying to get everything done before Monday. We would like to have our wall finished up before then. We bought Benq HT2050a. It will be located in our basement as part time entertainment. Mainly movies, little tv and some video games. We need help with figuring out paint. We have read forums after forums. See below on out current set up. Our walls are already dark but celling is light on color. The plain wall is what I want my screen to be. It is already sanded, just need primer and paint. Any help would be much appreciated.
