What is the best material for a projector screen?

What is the best projector screen material to use for the outdoors?

• I have just bought this projector: http://www.epson.com/cgi-bin/Store/ProductQuickSpec.jsp?BV_UseBVCookie=yes&infoType=Specs&oid=20540838&category=Products The screen would be placed near an outdoor roof so it would not receive direct sunlight. I got it used for $290. I thinking about buying this: http://www.newegg.com/Product/Product.aspx?Item=N82E16824999137 Is that a good choice or what do you recommend?I would prefer something that has a tripod or something similar. I was looking to buy booth the tripod and the projector screen separately so I could choose the projector screen myself but I could not find them sold separately. Thanks for any info.

• Answer:

  The projector you purchase is not even a 1080P, you could have purchase a Panasonic 3000 projector with 1080P for the same price and is rated better by Home theater magazine. The screen is sufficent for your outdoor use, a white sheet or a white wall will work also. But for the price you paid it's good. I was thinking about hooking up mine in the patio for the summer, an older panasonic 720P projector and 92" screen. Enjoy it.
