Hi guys!
I am working to create a dedicated home theater.
The size of the room is 15'x 19' x 8' and it has no windows so completely dark. I am planning on a 130" screen in 2.35:1 ratio..
Question 1.: I have read that there is an optimum screen size relative to the viewing distance and I would greatly exceed this with this screen size (I would be sitting too close to the screen) my thing is, what is the point of getting a projector and larger screen anyway if you just have to move further away from the screen? Using this logic, I can just get a 55" TV and sit at 3' away..
Is it a problem to sit closer than recommended ? I don't understand..

Question 2': Projector Recommendation..
I would love a 4K projector but I'm afraid these may still exceed my budget at this time.. should I just get a 1080P projector or hold out a little longer hoping prices will come down?
Also, since I am planning a 2.35:1 ratio screen I would prefer a projector with a powered zoom lens with memory..are there any affordable projectors with this feature? Also considering a brightness suitable for the screen ration vs the native projector ratio and the darkness of the room.

I have tried to do a lot of research but there is such a lot of stuff to deal with.. any help would be appreciated!

Thanks for posting the room size, but what distance do you plan on sitting from the screen? Typically people sit about one foot for every 10" to 12" of diagonal of screen size. Some go a bit larger, some go a bit smaller than that, but generally for a 130" diagonal, people will sit between 11 and 13 feet from that screen size.

What is your budget? This matters a great deal with your request for a 2.35 screen size.

To be clear: The 2.35 screen size question is a big one.

Is your room really ideal for 2.35? Are you using the 19' wall or the 15' wall? Do you now have enough height to put in a 150" diagonal 16:9 screen?

Keep in mind, ALL HDTV and about 1/3 of all movies made are in the 16:9 (or 1.85) aspect ratio and will fill the full height of a 16:9 projector. If your intent is 100% movie watching, and you will go out of your way to find 2.35 movies, then that's okay, but still, menus and other items will still full the full 16:9 frame.

I don't have anything against 2.35, but setting it up is rarely something I suggest as a first course of action. What may be better is painting the screen area a flat black and use black cloth surrounding the screen and make masking panels for your screen that you can just clip into place and mask the screen size down to 2.35. This way you don't need to drop $2,000 for an Epson 4000 (the least expensive motorized zoom projector) or more like $2,500 or $3,000 on the Epson 5040 or the JVC RS440 projectors.

The width stays the same, you never have to touch the projector, and when you put the masks into place, it will appear entirely like a 2.35 screen.

Otherwise, you will have to ante up for the $2,000+ projectors or get a projector with enough zoom range to cover both the 1.78 and 2.35 aspect ratio zoom range and have lens shift.

This is about a 1.35x zoom lens, placed perfectly in the room to fill both the width and the height at different zoom ranges, and a willingness to manually change the zoom and lens shift every single time you watch something in a different aspect ratio.

The Epson 3100 fits the bill for this at a reasonable price.

That said, the Viewsonic Pro7820 will work as a entry level, budget priced ($500) model on a 150" screen just fine and you have $500 left to build the masking system yourself, which should cost just a couple hundred dollars, even if you have to buy a few tools.

Thanks for this information. Very useful!
The main reason I want to go with the 2.35 ratio is so that the epic movies look epic.. and not half the size of a TV show.. this just doesn't seem right.. I see what you are saying about masking the top and bottom when watching a movie, I'm just afraid it will be a let down when switching from 16:9 content.. In the mean time, I have traced out various sizes on the back wall (15' wide) just to get an idea of the actual size. Sitting at about 8'-10' away, I think a screen with a constant height of 50" would look great (unless this would cause an issue with the resolution at 1080P? Will it become pixelated at this distance?) the way I see it, I can have a 130" diagonal 2.35:1 image and a 100" 16:9 image when I mask off 15.5" on either size of the screen. Having a smaller size image for 16:9 content won't bother me at all.. I see what you are saying with the zoom though. In order to get an image to fill both ratios I would need a 1.35X zoom, or else I would have to physically move the projector... Since I am looking to ceiling mount, not a good idea! Thanks for pointing these things out to me, with all this information out there it is hard to find the right information!

I like all my viewing to be epic, and I find that I get that with both movies and HDTV viewing on a 161" screen that I view from about 16' away. But, this is very much an individual choice, not a one-size-fits-all decision.

If you are going 2.35, then I don't see a world where you get away with anything short of the Epson 4000. I've gotta say, if I'm spending that much, then I'm calling AVS up to see if they have the JVC DLA470 for $2,000 still. They had some factory refurbs for that price, and it's a heck of a deal. Or I ante up to $3,000 and I get the JVC RS440.

For me, there is no in-between. I get entry level, or I get something that I will be completely happy with for 7+ years. JVC fits the later, pretty much any of the entry level DLP models fit the former. But, the entry level DLPs won't work for your 2.35 setup at all. You would have to go 16:9.

Understood!
I guess, like everything else in life, it comes down to budget.
I am pretty much starting from scratch on the theater and have to see what is left of my budget by the time I am done with the construction.
Thank you for helping me narrow down my choices!
