Ah, that's different. Can't say, as I love projectors and big screens. It would be hard to give up my 122" 16:9 screen for an 80" TV. Let alone my 128" diagonal 2.35:1 screen. http://displaywars.com/80-inch-16x9-vs-122-inch-16x9Oh copy that. I understand that and already have a 2.35 Seymour. I meant more about the comparison of the RS400 4K to a native 4K television screen/monitor.
