Hi a newbie here. was planning to get a PJ for my Home theatre room. (4m by 3m). Was wondering whether to get the X1 or screenplay4800. any suggestions? I understand that the 4800 is design for home theatre. And the ANSI Lumens are 100 more than the X1. And the 4800 cost about 600 more than the X1. Need advice before i purchase. Thanks guys.
