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 night it is less of an issue as the brighness at sweet spot is too high and moving off makes more comfortable, but at the cost of slight loss of contrast (this is subjective, without any measurements).

Here are some photos to illustrate its properties. The photos were taken in full daylight (cloudy weather), no light contorl with the same camera settings.

Blank screen:



With flash:


At projector lense level:


At couch level (1.5 meters below projector lense):


From the side opposite to window:


From the window side:


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.
