I have just finished getting the screen and projector set up. I haven't built a stand yet for the projector, so its still a not centered properly and the image hangs off the screen a bit. Using the XY PET crystal screen with slim bezel, it has 0 waviness to it that I can see and I'm happy about that. The projector is plenty loud, but I have a Klipsch premier setup I will be hooking up shortly.
First out of the box impression:
I turned the projector on, turned on Apple TV and the menu was nice and bright. Everything was crisp and honestly I feel great about it. Then, I turned on Interstellar and the picture was... less than stellar. The brights were bright and the darks were dark, but the middle colors, like faces and things in the shadows, were way too dark; it felt like I was trying watch a movie through dirty water. After some adjustment, brightness -2, contrast +11 or so, Power brightness to 100%, and turned off HDR, the picture has me at about 85% happy. I think my issue is that coming from a Samsung QLED that was on top brightness since I bought it, I'm used to being able to see every little detail in the shaded areas, while the projector has more of a darker feel to everything. This is still after only 10 minutes of adjusting by eye. The images on the apple TV that consume the whole screen when you "highlight" a movie, look stunning, so I know the projector has the capability, I think it just needs tweaking.
Here's some images of set-up and I'll have a Youtube video up whenever I finish centering the image and hooking up the sound system. (Screen assembly, On wall without projector, Projector at Optoma Menu, Screenshot from Blade Runner 2049)
