OK,ive been thinking about a projector for a while,and you guys are making it a little easier to jump in the water.so maybe someone can answer a question i have.in my room i would be able to mount a projector about 8' high,and the top of the screen i could get about 6' high and would be about 12 from projector.(the room slants down pretty low,its kind of shaped like the vp150.... hmmmm how did that happen)would the height differance throw the picture off,or are there controls to compensate for the height differance.and if there is,does the quality get worse.i can email a picture to help explain it a little better or try to put it on this site somehow....thanks Ron
