Projection Surfaces

My experience is that it's a good idea to sketch out your projector 
placement first. The image aspect is 4:3 so for a 3x1 image, that's 12:3. 
If your wall is 10' wide that allows for a display height of about 2.5'.

Check your projector specs for the corresponding distance from the screen 
for the desired image size. The zoom capability of the lens gives you a 
range within you can place your projectors. I recommend ceiling mounts for 
a permanent installation but in any case you need to work around any 
mounting interference from lights, pipes, beams etc.
