I am looking for a projector to use in my living room (lots of light colors). Using a 120" screen (1.1 gain) at 15'-9" to lens. Room has some ambient light during the day as a TV, but will be reasonably dark at night for movies. I do need lens shift. I now have an Epson Pro 810 (720p) and could use more lumens. Are these good choices for me?
