, First off congrats on the new house and the added bonus of it coming with a really nice HT. I have a few general comments on the room first. I really like how the room is oriented with a single long row and a closer seating distance for all. I am a person that finds immersion level very important and even more important than viewing angle, it is also more social and you are not dealing with risers and screen size limitation due to seeing over heads in front of you. So in that regard you have a great start. Your RLC speakers are nicely done in wall and the center is low enough to let you change screen sizes without doing too much. That’s another plus to what you have now. The room color is also perfect the carpet is ok also. I would strongly advise you to think about going darker on the ceiling as it will have a huge effect on your PQ going forward with new projectors. I understand the design idea behind the bright white trim and wall plates, door etc. but I would find them distracting also with the lights out.
Now about screen size and eventually a projector that supports the size and method of presentation you eventually end up with. I say presentation because with a 16:9 projector that they all are. It doesn’t mean motion pictures and all the rest of the streaming media we consume these days is intended to be shown as large as it can be on a 16:9 screen like you would with a TV you are used to. Projectors have the ability to zoom and change image size so you can do things like classic film presentation that use CIH (constant image height. Or you might want to embrace the IMAX movement in movies with movies like Aquaman or Dunkirk changing ARs between scope and IMAX and there is even a new standard coming out for the home market called IMAX Enhanced. An IMAX movie may be 1.89:1 and a flat movie may be 1.85:1 but they are not intended to be shown at the same immersion level. Likewise scope you have been watching for years under immersive on TV with black letterbox bars now can be shown correctly wider than a regular flat movie.
We don’t know what your likes are for immersion now and I will tell you 99% of people that just get into FP find within a couple months they wish they had went more immersive. Some people are fine with CIW (constant image width) like TV, but IMO once you see you can watch a movie like Dunkirk at IMAX like immersion levels you will be hooked by that aspect of FP. Some people watch streaming or even regular TV in their theaters we do every night, and no way is that content intended to be scope or IMAX immersive.
So before you jump into projector shopping take some time and think about presentation. There is a CIH forum with a lot of information also. The folks there don’t care much for the movement to IMAX but there is information there on alternate presentation methods.
One last question what is behind the wall behind the projector? If it is a room that the projector could be located in it is very effective way to add throw length and get the projector noise out of the theater.
