This may be a horribly stupid question (probably due to the fact that I know close to nothing about the features of projectors.... I'm not a newbie to HT but a newbie to projectors) but I'm wondering if there are any projectors that I could put on a side wall and still project flat on the viewing wall (like a left/right keystone effect type of thing). I have a very tall and long room. We have a ceiling fan on a very long downrod that pretty much negates the possibility of me putting the projector on the back wall (wife loves the ceiling fan). If possible, I'd like to put a projector on one of the side walls. So is this a possibility?
