[quote name='dandesign' post='1059855' date='May 22 2010, 01:44 PM']mate do u know any reputable companies or websites that sell good silverscreens? and also filters?

Ive heard that the heat from the lamps damage the filters so u have to put them a certain distance back from the lamp...How far we talkin?[/quote]The radiation from the lamps indeed are killers for plastic polarizers (tried attaching them directly to the lenses and they fried within 10 hours. After increasing the distance to 7 centimetres from the lenses they managed more than 50 hours without signs of depolarization (pj's are lcd's with 2500 lumens btw). Professional filters are stamped with the recommended projectorlumens and have no problems being attached directly to the lenses. The spars i use have 5000 lumen rating for instance and has been around for maybe 1000 bulbhours without any at all signs of wear.
I recently tried two different silverish spraypaints with unexpected good result. There's threads both on mtbs3d and avsforums about such paints. Plastic polarizers aren't too cheap but the material for a rig won't cost many dollars. It's more an issue of getting your hands on it.
You don't even need polarizationfilters if you plan to watch stereomovies only. The stereobright option in stereoscopic player supports lcd-monitors in a stereobright config. Instead of polarizers you simply put very cheap retarderfoils in front of the lenses. It ghosts quite more than using standard polarizers but you have no lightlosses from the projectors (i think it's actually even brighter than the spars which makes sense). For this simple circular polarized real-d glasses are enough. Get more pairs by supporting your 3d-cinema.

Guys, I have the reason for DLP's dropping contrast and brightness at 120hz...

Single chip DLP's always going to do this... I don know if TV's going to suffer the same , but Im going for Polarizer very very fast...
