Thanks to everybody for all of your replies. I will not be using this with a giant screen. It would be an upgrade from a Sony VPL-VW675ES projecting on a 110" screen. Anything larger than that and I get very bad eye fatigue. Overall I am very pleased with the VW675, I just wished that it had a bit more oomph for the HDR content.
I'm really after a vividly bright picture for HDR, great black levels and a very sharp picture. We also use our current projector to play video games, any input on that would be greatly appreciated.
My concerns are the lack of Dolby Vision, what sounds like some clunky HDR implementations, and the fact that it is tens of thousands of dollars for 5 year old tech. I'm also a little concerned about the noise level. Being laser driven and liquid cooled, I'd expect it to be very quiet. I never hear my VW675.
How has Sony's support of the projector via software updates, etc been?
