Hidden among a bunch of Samsung's product launches in last year's CES presskit was a very brief paragraph on the world's first 8K projector with wireless connectivity. The Premiere 8K is still yet to arrive, but it's already received the first certification from the 8K Association.
I use a projector for my main entertainment display in a windowed room and when I find myself somewhere with a good large 4k screen I’m very aware of how much deeper the blacks are and how it’s just a bit sharper on the tv. I don’t mind trading the image quality for having it mounted up and out of the way though.
