You might go for "Gain" (HP) and discover that the Screen's texture and tendency to hot spot is bad since you have a preponderance of lumen output...even in Econo/3D
You might damage Mfg Screen material mounting it. Not much needs to be said about the economic aspect there.
Any Screen material that cost less than $18.00 sq.yd is probably going to present some issue or another. But that is just barely more qualified than a "IMO" there...admittedly...due to my own "small" experiences with that price point.
The fact to face is that at 120" diagonal, yes...you can order up and use a "White" material....and get only the type of results a White can provide. High Contrast Gray material will be too much of a detriment as far as lumen conservation for 3D apps. Besides, anything sold as High Contrast material will be more expensive.
Locating a suitable substrate is your only real challenge...and that is also solvable. The end all is this....almost nothing MFG Screen-wise you can find anywhere and ship in is going to surpass what you can accomplish by using a solid substrate regionally available, and assembling your own paint out of locally sourced items, as far as "Expense out layed per Performance gained" value is concerned..
I was getting to that. mfg
(Mfg) = "Manufactured / Manufacturer"
Can you elaborate on the solution you gave earlier, Sintra? Can it be shipped to Israel?.
The latter would be prohibitive....but I'd be seriously surprised if there was not a Plastic Sheet/Panel Importer....if indeed not a actual Mfg
to be found in Israel Sintra is a US-Branding of a material described as being: "Rigid Expanded PVC Foam Sheeting (6mm)
Whenever possible I try to go an extra mile for overseas AVS'ers and help them get the materials assembled to DIY their screens.
Seldom does anyone run up against an unassailable Brick Wall if one wants something special to happen.
Good luck! ......and keep us well informed. We'll be here if you need us.
