Need Help on Projector screen size

[naeblis11]

I've tried several calculators to answer my question, but can't seem to find the answers.

I am mounting the projector to the ceiling. The ceiling is 90" high. Due to a cross beam I want to mount the project about 6.5' from the screen. The first row of seats will be about 12-14' from the screen. I'[m looking at an Epson Pro Cinema projector, but willing to look at others. The room light is well controlled.

My question is: Can the projector be mounted in this position and still get a good size (110+) screen size?

I can move the projector back behind the cross beam, however it will require the project to drop down, which may put it in the way of the second row of seating.

No. Not only is that distance not within this projector's parameters (8.3' - 14.8'), but to get an image with a diagonal of 110", this projector has to be at LEAST 10' 9" back (to the lens).

Look at these two sites. Sorry, you will have to copy and paste these links, I have not had enough posts yet on this site to be able to include links.

I had a bit tough time replacing our conference room short-throw Sony and in the end I found Toshiba was good deal for money as far as ANSI brightness and throw distance goes..

You can only get a 70" screen that way. You will need to be back 10' 10". Assuming your room is 20' to the back a rear shelf mount would get you a 110" screen from that distance

Perhaps you can rear shelf mount?

The problem is that you can't dictate where the projector goes, the lens on the projector dictates where it can go. ProjectorCentral.com has some great calculators for almost every home theater projector on the market which can help you see for yourself that you really can't put a projector as close as you are asking for.

Instead, get the projector back further and drop it down so it is just under the beam. You can often put it on a shelf at the back of the room.

While what you are asking for is not unusual, it is extremely difficult to get the optics good on a ultra-short throw projector. Every single ultra short throw projector on the market today has some significant sharpness and uniformity issues which is why home theater projectors are not available with ultra-short throw optics and even the short throw optics wouldn't be short enough to accomplish what you are asking even IF you had the several thousand dollar budget required to accomplish it.

Get the projector back a bit, it's the only way to get the appropriate 110" screen size.

Mounting on Back Wall

I suppose mounting on the back wall is an option. The back wall is 24' back. Is there any issue with brightness or image quality the further the pj is from the screen?

Being this far back will I be able to get a screen small enough. I'm not tied to the 110 in screen but it seems the further I go I will need a bigger and bigger screen.

How loud are these projectors fans? If I end up mounting just in front of a seating area, how big of a deal is this? I want to make the right decision, and want to be happy with the location. Image quality and movie watching being my biggest priority...

Well let's get down what you are looking for here first.

Do you ideally want a 110" screen for a light controlled home theater room?

What are the budget constraints?

Do you have a screen and if so what is it's rated gain?

Once we have these answer we can evaluate which projector would meet your need.

Further means less bright, but OTOH more contrast.

most likely NOT. And TBH, I prefer a MUCH larger screen than 110" from 14'. No question. However, I can see certain people preferring that. I'll note that you get most of the benefit of 1080p with this viewing angle, but definitely not the full potential (need to get closer to around 130" from 14' to do so).

Epsons are quiet for a PJ. Look where the vents are. If they are on the front, and the PJ is in front of you, it will then seem even quieter.

My PJ is louder than an Epson, it's rather low due to setup goals, and the vents are pretty much firing right at my ears, at least if I'm in the back row. Yes, every once in a while do I wish the noise floor was lower, but in any case, I'm not very worried about you.

The battle of a 24' rear mount seems to be the lumens vs size. The beauty of this PJ is you can shrink the size pretty easily if it's not enough output. For rear mounting I'd still suggest a Panasonic though. They have the most lumens usually. However if his budget is high enough he might have better options. At the first 1080p level I'd suggest the Panasonic for it's lumens. this will allow you a bigger screen if you prefer. I sit at 8 feet I guestimate and use an 80" screen. I personally like at least 10" per foot screen size.

24' feet is on the edge of the range though.

The Epson 8500UB will do it and delivers more light output than the Panasonic does, as well as better contrast ratio.

From 22'11" lens to screen (which is about what it will be when shelf mounted on your rear wall, and paired with a 110" Carada Brilliant White screen (1.4 gain) you end up with about 18 lumens per square foot of screen space which is well within THX standards for theater design.

This is what I would strongly consider doing if your room needs either really short, or really long throw. At the really long end (24' to back of room) you can do 110" screen size and get what you are after nicely. A bit more for the 8500UB, but this is also one of the best models under $3,000 on the market.

Yeah I just read that and it has the extra long bulb life and they usually come with other goodies. It's amazing how much projectors improve every year.

I am not hooked to any particular screen size. with 90" ceiling on this wall, and the need to put a center channel under the screen I was estimating 110" width to get me the correct height with a 16:9 ratio. (also would have to project under the cross beam in the middle of the room) I have not purchased anything, nor is the room finished yet. So I'm pretty much wide open.

I'm still debating whether to get a screen that would allow me to put the center channel directly behind the screen...

I would like to stay under $3000 for the projector. Reading reviews I was thinking the epson 8500UB.

Thanks for all the feedback. I'm still up in the air if I want the projector in front of me on the ceiling or on the back wall. Seems like putting it on the back wall is bad when people get up and block the projection. However, mounting it above and forward of the sitting area is concerning with walking into with my head and fan noise. (fan noise looks like maybe it's a minor concern from other comments.)

at 24' you could probably get a pretty steep line with the lens shift and a tall shelf. People get used to the getting up and stuff too. the best place is usually above you for fan noise.

I have been looking around and Im aware of many of these projectors "can" produce the brightness to be on my large 165 inch Dakane white screen. But I was wondering what would be the best 1080p projector for that screen size, or what would be the optimal lumens for the screen size. I am interested in the Epson home cinema 6500, the JVC RSA-HD20 or the optoma HD-806, also the Samsung SP-A800B if they have a discount. I do not have the money to afford one, but I wanted to know what would be the best performer at that screen size.

 

[AVRat]

Of those PJs, the Optoma provides the most light output to provide enough image brightness on a screen that size. PJs with 2000+ lumens are required. BenQ puts out PJs that should work well.
