A 120" 2.35:1 Dual layer White / Silver Milliskin Spandex Screen.....IF
(...and only if...) you can mount the PT-AE400U at 12' 10" and have the lens reside just under the top edge of the proposed Screen
Such a Spndex screen is extremely affordable and easy to make, and certainly lightweight enough to allow you to place / remove it from over the 55" TV.
But how long you can do so without having to re-cover the screen is going to be determined by how well your temporary hanging solution interfaces with the need and frequency to relocate the Screen. Once again, the affordability and ease of effecting a re-do is wholly in your favor, so there is that.
But also, even at the prescribed short throw, the Spandex will only provide you with at most 14 foot lambert of reflected brightness. That with a new Lamp. If 3D
is in the offing...and you have absolute light control during such times, then you'll make out ok until the lamp is really going south.
The other choice is a higher gain, solid Projection surface that while not tremendously heavy, will require more effort and care in relocation and storage, and a higher degree of "sweat equity" and expense. But the 2 main benefits are excellent. A excellent smooth surface.....and appreciably higher gain (1.4)
There are of course other options...high gain Mfg surfaces...but all of which will exhibit visual issues on such a screen, especially when higher resolution content is viewed. Not so with the DIY apps, and of course, you can Dine out in style with the Wife for a month on the difference cost-wise between any 2.35:1 HG Mfg Screen at 120" diagonal and it's DIY counterpart. A Month.
There's you response. If it prompts others to offer you more alternative, then even so, I'm glad to have helped.
Many thanks on your reply!!
I called and ordered 8 yards of the White & Silver Milliskin Spandex material, I ordered from the place you linked in the thread you had showing that screen build thread, I thought I'd buy some material, and give it a shot and trying it out, at least I'd have plenty left over for several screens!
My PM kind'of came up as a hurry up panic moment, so I hope I did not catch you off-guard, I have not been around here much, getting back in the AV / Projector fun... ( I could not stay away from here, LOL )
I'd like to make a 120 - 130" 2.35:1 screen ( depending on speaker placement width and drop down below the soffit ), with the dual white & silver spandex material, trying to decide a best approach on a light-weight frame, and having an outside border for black felt fabric, I would have to verify if I can mount the AE4000U to the distance you stated at 12'10", also I know, it's a difficult decision to take a fixed screen and set-up and take down each time is not practical, and doing some damage, where I may just give up and just order an electric screen.....
Also I remember you painting a electric screen, wondering how that worked out, it looked awesome, that may be another way to go, but I don't know much on electric, tab tensioned DIY set-up.
Again, much appreciate you taking some time and giving some feedback / suggestions!!!Edited by TheaterChad - 2/27/13 at 9:21pm
