Um, don't you think it should have been shipped on a roll? Those winkles and creases are absolutely ridiculous, or is that just what they send as a sample? I would not pay for folded up screen material .

This is the material, not sample. You can stretch those creases out pretty well, but yes I agree they should send it rolled, not folded.

At projector lense level:


At couch level (1.5 meters below projector lense):

So if you can arrange your set up so that you could watch from the projector lense level, this screen will let you watch anything at any time and in any lighting conditions. Otherwise, there will be lots of compromises. But this material is cheap enought to get just for the sake of trying it out.
what brand is this?

As stated above they ship the material folded for free, If you want it rolled make sure you tell them in advance and it may cost you something.

I can't measure it. If you want me to guess, it would be somewhere above 2. You may find more info if you browse throgh the previous pages.

Any Alternative to Hi-power (Elunevision) 2.4 that has the same or even better performance regardless of the price and can go as big as 250" 2.35:1 or 2.40:1?

I just found out about the discontinue of the products and if I know about this I would have bought them in advanced.

So sad...

No. The High Power / Draper Radiant / EluneVision PureBright screens used glass beads to achieve their gain. All other screens with similar gains use silver or optical coatings to get the gain up. Those technologies have significant artifacts like sparkles, sheen, hotspotting, and color shifts. The HP/Radiant/PureBright material isn't artifact free, but its slight "film grain" type artifact is so mild that it's rarely noticed.

I don't know what size PureBright 240 screens EluneVision still has in stock, but if you're looking for a high gain screen I'd contact them to see what's left. If they don't have what you want, you may want to look for a used HP.

I finally did get a return PM from darinp about the Roadstar reflective material. You were correct that he didn't think it was a viable replacement for HP. He said he thought the material sparkled badly enough to not really be a good solution for many people. I suppose it could be inferred from darinp's description that the reflective material might be good enough for the low price to satisfy some people who aren't sensitive to screen sparkles.

I have a 120" model c pulldown Da-Lite HP 2.8 screen that I am looking at selling (since I am upgrading to a larger fixed screen) and I am wondering if I should try to sell it locally or if its worth trying to ship something like that. I live in Regina, Saskatchewan in Canada so I don't think there is a huge audience for this kind of thing locally. Also, I would much rather sell the screen to someone that would actually appreciate it and knows how valuable the material is these days. I have only ever rolled the screen down once when I got it about 7 years ago.

Does anyone have a ballpark idea what shipping something like that might be worth? Would a place like UPS or Fed ex be able to package it up since I no longer have the package it originally shipped in? Just trying for figure out what it might be worth and how to factor in what its going to cost to ship to someone versus trying to sell it for less locally.

It would need to go freight and no clue on crossing the board.. I believe I have read folks trying to do this within the states getting quotes between $200 and $300 to ship. If you have the original box that may be helpful.. but still the shipping could cost what the screen is worth..

Ya, that was what I was afraid of. I think when it was originally shipped to me all those years ago it was only about $50 to ship which still seems crazy but maybe the cost was built into the screen to hide part of the shipping costs. Plus I am sure businesses get a much better rate than I would. I suppose I should get the dimensions and just head down to one of the shipping places and get an estimate.

This screen would be attractive to the right buyer if you can find a way to reach them. If I were you I would advertise it in the AVS Forum Classifieds at the price that you would like to get for it and say that the buyer is responsible for shipping costs. That will make your asking price appear more reasonable. As I recall from when I was pricing them a new 120" Model C with High Power fabric originally sold for less than US $500 including shipping,

I have not had this issue, you got a photo?

If it is just a small area I would first try Black Gaffers tape.. If you don't have any, buy role of 2" wide balck and you will wonder how you lived without it.. puts PVC duct tape to shame! http://www.goodbuyguys.com/catalog/i...hp/cPath/22_86

Looking at mine it wraps around the back and is fastened and reinforced at the ends.. The backing is fiber glass so I don't think you need to worry about adverse reactions of adhesive.. I would probably use contact cement as you would not have to clamp that..
For those who may not know how contact cement works, it is applied to both sides that be be adhered, allowed to dry completely then the 2 parts are pressed together.
The cement should be applied to each surface evenly so multiple thin coats are advisable allowing sufficient time to dry between coats and before adhering the 2 surfaces.

If that is not feasible I would use a 2 part epoxy that lists fiberglass as a supported surface to bond.
Good luck!

the piece that i am holding also forms the bottom of the image area.
so i cannot put tape on it as per da-lite. that is, unless i make the image area that much smaller.
da-lite also said that any cement/glue could make the screen rot (not exact words).
i was thinking super glue.

talking to da-lite = idk if i was chatting with a tech or just a sales person.
their other option was to "just" replace the material, lol, idiot.

That seems very different than mine.. there is black across the bottom of the screen above the bar.. and it wraps without a seam front to back, where it has the seam..

So maybe it is the same.. looking at where yours is coming apart, the screen surface actually looks to be higher than the black part as if the fabric is one piece but is obviously adhered to the back at the same point.. hard to describe in words..
Yeah after another look at your pic I am fairly sure there is no difference in them..
I would do some testing of white artist tape for a boarder to line up the pice you will be glueing.. it is not real sticky but would not want it to lift any beads off the screen..
Then test a small spot with the contact adhesive. I would also take it down to work on it..
Good luck

ok, i fixed it.

i just used super glue = i buy the 4 pack for $1.50 from walmart.
the left side looks as though it never separated . the right side, i didn't get it exactly lined up. its a few .001"s low in a place = non issue.

the glue seems to be holding just fine. and no visible issues that i can see = discolorations or whatever.
i will be, forever, keeping an eye on it. but i expect its fixed.

on a side note.
my screen has 2 new friends.
14cf each, the screen is 2' out from the wall and the subs go back to the wall.
