Optoma claims that its new DuraCore ProScene laser projector is rated to throw images with a brightness of 7,000 lumens. It is also short-throw, which means it can has use-cases up to and including whole-room, 24/7 immersive effects. The ZU720TST also weighs only 28 pounds, which could allow one person to mount it, even to a ceiling.

Short throw...I have to assume is not UST, since the projector won't even be able to clear the image if it projects from the front sitting within a meter of the screen. The weight also looks a little suspicious if it's this bright and liquid cooled. Personally I wouldn't touch single chip DLP due to the rainbow effect.
Projectors are truly not in a good position to compete with panels, the future is still μLED. I suspect projectors have less than a decade before high end home cinema is entirely taken over by panels.
"It is a fixed-lens projector, although those lenses are also interchangeable and supports a up to 1.26x zoom."
Make your mind up!
