I am trying to help my friend setup HT in a non dedicated room. I am thinking about RS55u or RS65U for the PJ. From what I understand they are 4K projectors , so everything is scaled up to 4K. How does it handle 2.4:1 material. Do you still need anamorphic lens , or since it has high enough resolution you just used available pxels in 2.4:1 range? What is the maximum width of screen ( will need to be motorized drop down screen) will you recommend and what aspect ratio. He most likely will not prefer to have A lens as it is a family room. Ambient light will be moderately controlled and hence all the critical viewing will be done at night. 3D is not a requirement , but since it is anyway included in JVC's , its a bonus.
