Also, is the spandex screen only useful in a controlled lighting area because I really want something that is universal and willing to sacrifice some brightness in order to obtain better quality in all lighting conditions and most viewing angles

this is all PJ dependant....use the projectorcentral.com calculator for your PJ then set the gain fo the screen

.9 for white/white
.8 for white/silver
.7 for white/black

I have white/black and have watched in full daylight with no curtains...and it was quite watchable...washed out a bit but nothing unwatchable...this is with a panny 8000 from 14' on a 130" 2.35 screen

ymmv

Does anybody have a step by step guide on how they applied the spandex and how does the quality look from the side view?

Sorry to keep flooding the forum but I need to figure this out. I know most people are using the spandex in order to have the AT capabilities. Is there away to use spandex an not worry about AT with just 1 sheet or do I need both if I wanted to go the white/black option. Can I use any black background ex matte vinyl,black sheets,black acrylic, black poster board , black paint. Im aiming for a gain of .7 and trying to get the best of both worlds. Darkness with Contrast Distinction.. HELP

If you want a gain of .7 why not just go with 2 layers of spandex white/black? Probably the cheapest and easiest.

So my next question is, Should I order Black MoleSkin or Milliskin for my back layer.

In simple terms, should i use mole skin for the rear layer if Im not concerned about AT? to eliminate excess real lighting and bringing out more contrast.

I have the epson 8350 14 feet away currently 125 Diagonal.
Screen gain of 1.0 producing 17fL.
I want to downsize 98 diagonal which if I stay at current settings would give me 19fL.

.9 gives 17 fL
.8 gives 15 fL
.7 gives 13 fL

So truly that 4 fL of possible loss based on my current 125 diagonal screen. How do I distinguish between which would give me the best picture quality i have no need for the AT unfortunately .

After 5 hours of labor, I final made my spandex zero edge screen. With the Led backing. Please not that the pictures are in motion and the first picture is with every single light on facing the screen. And the second is in complete darkness.
I used silver over black. I had a 4 types of spandex. And the silver top layer worked best for me.

Hey all, noobie here surfing at work, and am completely overwhelmed haha. I've recently decided to convert my basement to a HT. It's a large room, half dedicated to the theatre, the back side of the room is up for grabs currently, probably a bar area. Anyway, I snagged a w1070 at a solid deal on cybermonday, painted the room on a whim on my last two off days. Black screen wall, kendall charcoal on all the other walls, unfortunately still a white ceiling/trim. I didn't pull the trigger on painting the trim/ceilings dark to keep some of the "appeal" to the room, as it's a large part of my basement/main floor (bi-level home, walk in downstairs, walk out upstairs in the back yard).

Anyway, I've got the room painted, my pj sitting, mount on the way, and I'm off next Fri/Sat/Sun and plan to get everything together. I've settled on a DIY spandex screen. Painting is out because my room has tacky wood paneling with grooves and I don't feel like filling/sanding them all because I don't trust my abilities in that. SO I'm tracking on the frame and all the pieces to build that, I'm capable when it comes to this. I'm thinking white over silver will suit my needs. The room will be used mostly at night (I'm a night shifter, so I keep late hours) and is semi light controller. Blackouts have been put on the two windows, and it's pretty damn dark. My issue right now is the silver you all speak of is out of stock. I'm looking at a 13.5' throw for a 124" screen.

Any w1070 guys here with some feedback? Is there anywhere else to get the silver other than spandex world? 3.5 yards of each seems correct for my potential screen. Thanks guys, please go easy!

You could easily get by using white over a simple light or middle tone gray spandex.

You didn't mention what size screen you were hoping to get, but using grey over white would be a way to have that projector produce better black levels, as long as it will not be hindered by too overly large a screen area

But do yourself a not too small favor of painting out the area of the ceiling directly over the screen and out about 4 feet, with the same gray or a darker shade of gray as was used on the side walls . Just about anything darker than white. That minimalist approach will basically encapsulate only that one end of the room and serve to isolate the screen area, making it appear to be much more suspended in space, as well as a void having the screen grossly light up the ceiling at that end of the room.

Thanks for the tip MM, I'll give that a try. I'm looking for 120"-125" screen size (based on projector calculator). My mount should be here in the next few days, I'll have the final number once I get everything mounted up.

Also, I grew up in Hattiesburg, go golden eagles!

Picture below for reference. Looks like moleskin matte silver with milliskin matte white is the combo I could go with.

Wondering if anyone has tried the shiny milliskin as the second layer? Would a white over shiny silver provide a higher gain screen? I have a W1070 at 12 ft and looking for ambient light setup on a 130". Any worries about hot spots? Spandex World is currently out of the matte silver so I am looking for an alternative if the shiny isn't an option. Any suggestions?

chip85,

If ambient light viewing is needed and you cannot wait for Silver to use as a top layer over White, the best you can really do would be White over Black, or any dark Gray.

Eric the Ricer,

Using Moleskin as a Rear layer is perfectly fine. Not so as a Top layer because it has a less fine weave that is noticeable when viewing content.
If AT is need, avoid using Moleskin....for any layer.

Screen I am building is a 120 X 68.

Built the frame and am planning on wrapping the frame with velvet.
Question is how much velvet should I buy for wrapping the frame? Do I need 4 yards (12 ft) to cover the length of the frame or can I manage with 2 yds?
If I buy 2 would the seam be visible?

Thanks

Built the Frame?

Do you mean the frame used to actually hold the screen?

Wrapping Velvet involves wrapping it onto individual pieces of Base Board Trim (3.25" x 1/2") and then attaching them to the "Screen Frame".

And yes.... for a 120" wide screen you would need to purchase 4 yards. Attaching Velvet in sections is not really advisable.

You could use ProtoStar Flocking Tape (1-5/8"" wide)
http://www.fpi-protostar.com/hitack.htm
....look at the bottom of the List.

With that you could apply it directly over the solid edge of the Frame.

Thanks MM.

Sorry I should have been more precise. Frame is the screen frame.
Should the velvet wrapped base board trim nailed or glued to the screen frame?

Thanks again.

Trim Nailed is best, using 1" to 1.25" Wire Brads. Have a Nail Set handy to set the nails below the surface of the Velvet.

Got my spandex and PJ mount in the mail today. Planning on mounting before work tomorrow and getting the final screen size. Weds I'll be building the frame and getting everything put together.

I may have overlooked some of your comments in this thread, but how are you all mounting your screens to the wall? Thanks in advance!

French cleats are the usual method, whether purchased from the big box stores or made DIY.

Here is a simple illustration of a French Cleat made from wood.



Doing such allows you to make the needed Cleat as long as you want to, and one 1' x 6" x 6' Piece of Poplar can make 4 French Cleat sets for less than the price of one "Hangman"

Also, has anyone tried the "Shiny White" Milliskin to increase gain with silver backer? I have a JVC RS1 and I am worried about brightness on a larger screen (150" ish). It isn't the brightest on a 120" now but I have a new lamp coming in Friday so we will see after that goes in where I am at.
