Another thing to consider is how far back you plan to sit. Generally for a 16:9 (1.78) screen you want to be about 1.5 times back the screen width. It appears your screen is not all that big, so if you planning on sitting back at least as far as the projector, you might find the screen looks to small from that distance.
