For less money you could get a 120" Blue Ocean rear projection screen and a Canon 5000 lumen LCOS projector with .8 to 1 lens throw ratio. You would need 9 feet behind the screen. Your electric bills would be allot lower, but you would have to change bulbs every 3,000 hours. The Canon contrast ratio is only 1000:1 but that makes no difference for lights-on viewing. The contrast ratio numbers are deceiving, and most people like the Canon blacks even with poor claimed specs.
