BenQ - TH585

Alternatively, you could get a 142-184 inch screen and mount it at 4.6 meters lol. Also the 585 is a massive step down its only 60Hz :( Don't sacrifice performance for no reason. You can easily ceiling mount this guy or get a larger screen or throw it on a coffee table. It really doesn't make sense to trade functionality over a single extra installation step? The throw ratio is really good on the 685p and the 585 is only minorly better? Save yourself from yourself here man... The screen you linked literally comes in a 150 inch version if you can't ceiling mount it just grab that instead its like 50€ more

This 👆.  Check on projectorcentral and see if the throw fits your size. If so it’s a great image and both go on sale for $499 pretty regularly

For $800 you’re looking at 1080p not even pixel shift. You’ll have to do the math on throw distance but an Epson 1080 or Benq 585 are decent machines

My screen is 2.3m x 2.7m. I currently have a benq th585 standard throw which gives a decent picture. Nice brightness. Etc. I'm wanting to upgrade and tossing up between the benq th671st and the optoma gt1080hdr. Ideal mount distance is 2m from screen. Directly infront of that rollerdoor motor. Any suggestions on which would be better suited for me? Looking at the projector calculators I think it's telling me the optoma is about 2m away and the benq is more like 2.8m. If I'm doing it right

BenQ TH585 would be a good choice since you need a LOT of brightness given your situation.

If worried about brightness consider a screen with maybe something like a 1.2 gain. Also I would prioritize a projector with 3000+ ANSI lumens if that is a major concern. This won't be easy and definitely need to go used with your budget. Anything new under $300 that claims more than 1000 ANSI lumens is extremely likely to be lying about it. Maybe look for refurbished TH575 or TH585 as they are really bright and considered good for gaming. Not competitive FPS gaming but that isn't your concern so they are more than adequate. PS don't forget light will still be an issue. Nothing you do especially in this budget will fix a room full of bright sunlight or similar. Movie theaters are dark for a reason. The 3000+ ANSI lumens ones will allow some lights on but at 150" even that will be limited.

That’s the worst one u could buy. U gotta go on Facebook marketplace and look for a used benq or view sonic. Just make sure its 1080p and 2500+lumens and you’ll love it

I went from cheaper 70inch 4k Samsung to benq 1080p projector I purchased on eBay. Even though the resolution isn’t as good I prefer the projector by a long shot. I love it

Have a look at Richer Sounds. I picked up a BenQ 1080p projector for £200 and gor a discount for signing up to their newsletter. It was a return / open box. I was projecting almost my full wall height - it was amazing. Room layout change means a smaller projected size now but still great.
