I am almost finished building my theater (see picture below). The room is 32x16. I will be running an Epson 3010 with a Mudmaxx 2.1 Retro (~1.4G)

Using the full zoom and hanging 5" from the ceiling

Option 1:
I can set he PJ back 17ft and able to obtain a 160" screen

Option 2:
I can set the PJ back 15 ft and able to obtain a 144" screen

What seating distance(s)? My front row is 12 feet from a 136" wide 2.35 screen, pretty immersive, and the way I like it.

In that case, the 144" choice (width I assume) sounds about right, 160" would be too big - that's personal preference, but I do tend to already be on the immersive / sit close end of the spectrum compared to most.

LOL, it was a long weekend..

I have a painter and gave him the gun specs that you suggested.

I will most likely use SyFrabics for the black edges. Only part I am confused about is how to lay it out since I see most are using 2.35 but not sure how that works when you have movies like avatar and tron that change aspect ratios during the film.

for most of us... that means having the largest 16:9 screen we can muster... so that 2.35 movies have the same emersive feel without having to fiddle with the zoom. (this might include making additional horizontal masks for 2.35 movies)

for others that means getting the largest 2.35 screen they can handle and then resize/zoom down the image for 16:9 movies. (this might include making vertical masks for 16:9 movies.

obviously, having a pj with programmable lense shift is highly desirable in both options.

once you've decide on which option... then you can go about either making

A mid-film change will leave you stuck unless you decide to change parameters at the Pj itself. But there are several methods to optimize the use of any/each Format. Some simple and cost effective...some complex and expensive. If size matters, then dropping down significantly in screen height when switching from 16:9 to 2.35:1 isn't going to leave you very happy, let alone satisfied.

I look at your Screen wall and see 16' (192") wide x 96" high w/45 degree angle up right that comes 6-8" down from the ceiling.

144" diagonal = 126" across x 71" high **

96" minus 71" = 25" Place Screen's bottom edge at 18" off Floor, leaving 10" between top edge of Screen and Ceiling. Or crowd the Ceiling with a 6" spacing and gain another 4" at the bottom edge out to 22' off the Floor.

Side to side.... no issues there with dark Side Walls and 33" distance between each of the side edges of the Screen and each Side Wall

Throw distance is 19'. PJ Mount Chief RPA 168 w/Peerless ACC 570 ceiling Plate and 2" Threaded Nipple. ( Bottom of PJ is just 7" down off the ceiling )

**Now here is something to consider. With all that extra "Screen Wall Width", you could go with a 69" x 162" 2.35:1 Screen (176" diagonal), that gives you a 69" x 123" (141" diagonal) in 16:9.

While there's not a whole huge loss of height and width in 16:9 ( 3" both ways ), there is a tremendous gain in width and height in 2.35:1 that equals a 176" diagonal as well as a gain of almost 20" per side of viewable area.

That's called "Constant Image Height" and even at 162" of Screen width, you still have room (30" Total...15" each side. )to have a simple Travis Rod "Pull type" Black Velvet Curtain Mask you can pull in to frame the 16:9 content.

If course this is dependent upon you getting a PJ with at least H&V Lens Shift capability. The 5010 has that...is brighter than the 3010 with extremely better Contrast. if your really going to get value for performance...I strongly suggest that the 5010 is to be considered.

Otherwise, get a Epson 8700, because that can do this job almost every bit as good (almost) as the 5010, and better than the 3010.

Thanks for the advice both of you...

I am going to be sticking with the 3010 since the wife about killed me getting that and spending the money. I just bought a Panny VT65 about 8 months ago so she was not looking at a new TV for a while...

I want the largest screen possible. but, still keeping it clean not grainy.

Here is a crappy picture on the primered wall to give you an idea on size that I am shooting for. Keep in mind the projector was placed on the floor in these photos vs. ceiling mount when completed. * Tron was in 3D mode so that will not be as clear.

2.35 I think


16.9 in 3D so pardon the not as clear image
