Posts 60 and 61 from Ellisdj and Bigboss - in one of the AVForums podcasts four months ago, Mr Steve Withers was saying something very similar, about how good a 1080p projected image could still be. He said that even having just reviewed the excellent 4K 75-inch Sony KD-75X9405C television (which would be on my money-no-object list if ONLY it didn't have those very good but non-detachable speakers at the sides, grrr!) he would prefer his own 10-foot screen energised by his projector. Listen to the relevant bit of the podcast here (press the arrow on the left, then click on the solid black timing bar, from 23 minutes 20 seconds elapsed for the next five minutes) https://www.avforums.com/threads/avforums-podcast-22nd-july-2015.1970596/. As it happens you'll see from the podcast index that the first main item discussed the Sony television.
I can still remember how impressed I was with Bigboss's projector and screen combination in March. Eight months on, I've not seen anything to touch it. That said, tonight I was, unusually watching a film in my biggest and best setup (on my Panasonic 65VT65 in the parlour, normally I watch the LG 60PZ950T in the kitchen). The Blu-ray was Fury, starring Brad Pitt, and I was running my 12.1 sound system (with the SVS PC13-Ultra (old-style, 750W amplifier) and I was thinking "This looks and sounds better than at the cinema!" Which in truth really isn't very difficult, the last film that I saw at the cinema, Everest, was slightly but definitely out of focus. And don't get me started on the sound in some cinemas!
But I don't dispute that, content though I was tonight with the picture from Fury on my Panasonic television, your two projector setups are significantly better. And yes, even just on my Panasonic, I was thinking - this is pretty sharp, how much better can 4K be? Perhaps 4K and HDR and all that would be much better again, but as Steve Withers says in the podcast, I'm pretty happy with what I have.
