I’ll give you guys more pics and dimensions next week when I start the prep phase of this project.
This will be the third display tech for this custom theater that was built around 2004. Originally, it was built with a, coincidentally, 146” diagonal screen. Lots of ceiling height, so I was able to mount front channel speakers above and below the screen. Due to ignorance on both my and my theater designers part, we built the projector such that it was quite a bit higher than the top of the screen (three rows of stadium seating). We then had the challenge of finding a projector that would work without a ton of keystoning. The ONLY HD projector that would work was the JVC QX1, which, as it happens was a fantastic projector. It had a 4x3 output of 1920x1536 pixels. So we could project HD on the lower 2/3 of the screen and project “black” on the top third and it worked well. That projector had such dark blacks that you didn’t notice this hack.
A couple of years ago I was itching for a 4K projector, but couldn’t find anything that could handle my unusual physical set up. I ended up replacing the QX1 with a high end Sony 4K projector. I had to make the screen larger by futzing around with the curtains, moving the front channel speakers behind the screen, using a perforated screen, and finally living with a slight keystone.
But I haven’t liked the result. The screen is now too big. The first two seating rows are now too close to the screen, and the back row is the only row people like sitting in. The perforated screen muddied the center channel and I had to eq compensate for it. And finally, AppleTV 4K HDR content is either washed out or too dark. I can’t get it right.
Needless to say, I’m really looking forward to having an active display there for the first time. It will fix all the problems I introduced two years ago and should be awesome. And by a stroke of luck it is exactly the right size that the theater was designed for.
