VPL-VW890ES

I have both a  Sony VW890es laser projector that shoots to a 3M wide 2.40:1 scope screen and a Samsung 65" OLED that sits just behind it. My projection screen flips up when I want to use the TV, so the same sources, amps, speakers etc. are used for both display systems. I started out with just the projector in my light controlled room, and have zero problems with. It's bright, immersive and on the scope screen, delivers  movies as they are intended. I also have a Lumagen video processor that manages aspect ratios for me and handles HDR content as best as is possible with a projector. I purchased the TV really to save my projector.. I found I was watching a good deal of YouTube or non-event TV and was fairly racking up the hours on the projector. This was my first OLED and I found myself a little underwhelmed. Yes, it's much smaller than the projector set up, and on the same seating position it's diminished further. However, the particular Sony PJ I have is bright and sharp as a tack so I wouldn't be raving about  the OLED in comparison, and to my mind, nothing beats the impact and immersion of a movie event on the 2.40:1 screen. You just can't get that sense of occasion from a TV, though I am looking forward to the future and microLED video walls.

while im not contributing meaningfully to your question, sorry - i'd love to know, too. we have a LG C6 my uncle adores and a sony 4K 3D projector from 2020 that's quite frankly underwhleming compared to the LG C6. if there's any better while offering 4K/HDR, i'd LOVE to know to recommend to him

I think the AVR and Projector screen are a little high depending on what they have picked out. Is it going to be a fixed screen or a drop down? Black ash subwoofer seems like its an SVS, so they are likely matching the in ceilings to match that quality. If you want it done for less, buy your own equipment, and have them install it or find another company that will. Sony makes a great 4k laser for about 5k so that will cut the cost dramatically

God no!! Upgrade to one of the laser based 4k projectors! My fav is the Sony, but there are several to choose from. I think you’d be so disappointed losing that much screen! It’d feel like….. you know, A TV instead of a theater!

I went the open box route, got a 4K Sony and never looked back. Sony optics and picture processing are the best available and their projectors are true 3-chip systems and native 4k.

Open box JVC or Sony will be your best option at that price. They are both true native 4K with 3-chip light engines - so no rainbow effect or pixel shifting. Personally I prefer Sony for their optics and image processing. I actually kept my first Sony 4K in storage after upgrading. It was a demo unit which I got for under $3K.
