nice! you've got me beat.

also, this is meant mostly to be a fun thread... and also a how i did it thread as well. so i encourage folks to post pics of how they did it... and definitely their completed screens as well.

this is one that i'm currently working on... 145" diagonal (71" x 126.5")
made from three sheets of 8'x4' pioneex white tile board and framed using 1x3 select pine boards. boards were butted together and the frame was easily constructed using 1x4 and 2x4 frame hangers and a hammer as my only tools.

a work in progress...
first pic is the backside framing. second pic is screen on wall and working on removing the seams.

OK, I guess I just make it, 125" x 70"! I built an acoustically transparent screen that has replaced my old 92" wide pull-down screen. The difference is staggering, especially with 2:35 material.

It's easy to demo the difference since the screen height is the same 16:9 (69") and 4:3 (69") plus or minus. I simple switch my projector from 4:3 to 16:9 and tada, instant comparison. The 92" wide image looks ridiculously small by comparison and the image holds up amazingly well, which, I must admit, was a concern. Since I'd been using the 4:3 ratio on my old screen there is no difference in brightness between the two.

I never thought I would hear my wife praise any of my little projects but she simply said "WOW" and sat back to watch "Phantom of the Opera". Not one of my favorite movies, but I must admit the "Masquerade" sequence is stunning.

Question, why the start at 125", just seems like a funny number even though it works for me!

Outdoor theater comprises of (3)48" x 81" 1" thick cardboard panels. Basic flat white paint for screen color and white artist tape to cover edges. Each panel weighs about 7lbs and can be taken down in 10 minutes

total cost of materials: $0.00





Closeup- once the movie is on you don't even notice the seams

Very cool victor-eyd.

What stereo system do you use in your outdoor setup?

Just a hodge-podge of stuff lying around. The system is dolby surround but with dual centers and powered sub to fill out the bottom-end. The speakers are some nonamer chinese-made flea market specials my brother gave me so the cost of the system was also minimal, ie free

The system is permanently mounted in the garage- I just run long lines of speaker wire to the speakers when I want to watch.

134" diagonal EluneVision (1st Generation) screen.

(That is a 7 foot tall door next to it, just to give you an idea of scope!)


No pretty felt-covered frame, but the black, painted aluminum suits my batcave just fine.

1 row of 3 seats a mere 13 feat away. It truly is like being at the movies.


Notice only 6 inches on either side as the room is 11' wide and the screen takes up 10 feet!

Certainly you can. If your a Hammerhead Shark, with eyes on each side of your head.

No, really now; conventional wisdom has always dictated that at least a 1.8:1 ratio, Seating distance to Screen width be observed. This was due to several factors.

Resolution
Screen artifacts
Brightness level at screen's center
.......and comfortable viewing at the peripheral edges of one's vision. (no Head twisting)

At 6' from a 10' wide screen, issues arise. Resolution can be aced. But unless you have a truly "pixel-less" image from your PJ, even a 1080p unit will show some image structure.

The width of the screen will fill your vision, and probably not exceed the peripheral edges of your viewing cone. But side-to-side eye movement will HAVE to be a part of your experience. Constantly. Your eyes WILL tend to focus on the center of the screen, and to see content at the sides, either a slight twisting of the head or a sideways roll of the eyes will be required. It can be something you do not seem to notice, but it will wear you out over 2-3 hours, and for most, give you considerable eye strain and potential headaches.

Also, a 120" screen, if not 4:3 in nature, you screen is 59" tall (just under 5') Given that you'd at least mount such a screen at 24' off the floor, that places the top of the screen at 7'. That's at least 3' above your level of eyesight as you stare straight ahead. If you recline to see better, you'll be watching movies between your toes. But immersed in the content you will be.

IF it's a 4:3 screen, it just get's worse "Height wise" (....or better if your a masochist ) because such a size screen is 6' high. Your gonna be craning your neck to watch. But the width is reduced to 8'.

The Elunevision screen a few posts above is 134". Thats 80" x 107", both well under 13' yet he states his experience is "just like being at the movies". He's at about a 1.2:1 ratio

I'm an advocate for being able to suggest a 1:1 ratio, and do so almost all the time. 1.2:1 at most. But I use screens with completely smooth surfaces, and PJ that excel at delivering nearly smooth, or completely smooth, pixel-free images. But I know the limitations for practical viewing for extended periods of time, and the best image "in your face" will wear down the most ardent advocate of "HUGE".

But some do not follow such advice, opting for wall sized imagery if at all obtainable. To each his own, but to those individuals, a quick web search for a local Opthmologist is also recommended.

Thank you for your detailed explenation.
From this I understand that if the viewers site at 350cm from the screen , it means (divided by 1.8) that an optimal projection size will be around 200cm width which is 90" diagonal ?

How do I calculate the distance from the floor that the image should start from ?

I'm bringing this back from the dead, so sorry My question is this- how would a (approx) 9 foot seating distance from a 106" screen work? Im putting a projector in a spare bedroom which is only 10 x 11 x 8 so my space is limited.

Should I stick with a 92" (or smaller) screen?

After my mom saw my set up she had to have one for herself. I made hers quite a bit larger than mine since she has such a large room.

The pic if from a cell, sorry. It measures in at 143" diag, I believe it is about 10 1/2 ft wide and about 6 ft tall. You can compare it to the open doorway. They have 10 ft ceilings so we left just enough room for the screen to fit between the Infinity SM 125's and the crown molding. Unfortunately she likes alot of clutter if you couldn't tell.

This is the DIY Screen Forum, and the 125"+ Club pertains to DIY representations.

We are not stinkers or uppity folks, but please consider that achieving a great 125"+ screen via the fruits of one's own DIY labors is quite a difference from "ordering out".

Ya should'a been following this Forum before and you'd have enough cash left over for a 1080p HD-DVD or Blu-Ray Player. AND a bunch of HD DVD's to boot!

I built a 10.5'x4.5' scope screen several years ago. Used BO cloth and some pine to construct the frame, some black velvet-y material for around the frame, industrial strength velcro to put it on the wall (so it could be adjusted, which is easier than adjusting the giant CRT projector hanging from the ceiling). I painted the BO cloth with Behr Ultra White. Looks pretty decent

I want to make a curved AT screen of the same dimensions next. Trying to figure out what screen material i should use for that.

While I don't have an actual screen, I'm throwing a 145" diag (70"x126") image on a painted brick wall. The screen build is forthcoming...once I decide method (stretched fabric vs drywall) and save the $$ for it.
