So, I've got this crazy room on the roof of my building that is mine, it's an old water tower converted into an 11 foot diameter cylindrical room with 18 foot high ceilings. It is a very bright room, but there is a shade I can bring down and cut a good amount of light out. I'd like to use the room as a lounge and/or maybe a imax like theater. I'd like a really bright projector to project onto the wall, the wall with it's curved shape may warp the image a little but it looks pretty cool from the test I ran with a V300W i had, but something brighter would be better. I could spend over 3k but I'd rather not. Any suggestions?

Well I think you win the prize of the worst possible room to put a projector in. It will definitely be a challenge.

As the others have said this is a worse-case scenario for a projector but I sense you just want some sort of novelty. The NEC V300W already puts out 3000 lumens and you want brighter? Then pay a visit to Projector People and look at their conference room projectors that output 4500-5500 lumens in your under $3000 price range. Although you'll be able to focus the center of the screen the sides will be out-of-focus because of the curved walls. Just get yourself a nice 60" HDTV and call it a day.

WOW!


as a guy who does live video manipulation for events (concerts EDM shows) And as a guy who has done full dome (planetarium) video work, I've got to say I am envious of that room. If i had that room in my place I'd have it tricked out like you would not believe!


First thing.. you didn't provide dimensions of your room, as in projector placement options? Figuring out your throw ratio is where to start, and then you can get some idea of what projector(s) to use for this. Also how much area do you want to cover then entire thing floor to ceiling? how about the ceiling, that to? What kind of things do you see yourself projecting, movies, or are you thinking ambient video to use like decor? how important is resolution to you?


with a budget of $3000 you'll have to keep your expectations realistic. A used Panasonic PT-D5500 (5000 lumen) projector will set you back about $1500, and a 0.8:1 wide angle will set you back another $1000, but is that enough throw? if you need a shorter throw then you'll need to break the signal up into multiple ultra short throw projectors, and use software to edge blend it all together. There is some really decent priced multi display software available these days, and it's fairly easy to use.

That would be fun to watch one of the Cinerama films in there!

Aside from the distortion I would agree that you would have a focus issue if you go too wide.

I worked in a planetarium that had a full dome 35mm film system and like Cinerama the peripheral vision aspect was great


That new BenQ W1080 short throw might be worth looking at.

Thanks for the help. Some of you are saying "worst room ever" but my proof of concept setup in there is pretty epic to play xbox on. You can't see much if any focus issues with the projector I have now (granted I'm no expert, but for xbox it's been great). It's got about 13 feet to the wall. I'm going to keep playing with it and have some visual artists come checkout the space. Will probably lean towards a lounge instead of a media room, but we will see

Maybe we are missing something in your discription. If its 11' in Diameter how do you get a 13' throw?
