Just bought a Sony HW50ES, have the Screen Innovations Solar 4K 120" 2.35 diagonal screen 1.37 gain, mounted 13.5 feet from the screen and using supplied 3D glasses. Oh and 100% light controlled room, I cannot improve on the location.
Almost there but still a little dim for my taste. I thought the Sony VPL1000ES would do the job but just read another article claiming this unit is too dim too.
