    Hi. I've read somewhere on the net that a polarizer filter can reduce the dreaded rainbow effect on DLP's? Is this true and where can I get one? I don't normally see rainbows on my pj (H57) but last night I watched Fight Club and there were rainbows galore!! Don't want this to be a temperamental thing as it might cause me to sell the pj and go LCD rather.

    Thanks in advance.

    You need an NDx2 photographic filter , this will tone down an overbright pj and will eliminate any rainbow effect. I use a 62mm on my 4805, not sure what size a H57 would need though? Multi coated are the best to use.

    Mojo,

    I'm not convinced that slapping an ND filter on the lens will "eliminate any rainbow effect". If only it were that easy...

    Orangeteam says he doesn't normally suffer from rainbows. Therefore the NDx2 will help on the few occasions he talks about. For the small minority who suffer badly from this effect then maybe LCD is the way to go?

    Thanks for that. I'll try the filter you recommending. I must just find out which size! Anybody know?

    On that site they have 2 NDX2's listed. Which one is it? The Hoya HMC Filter NDX2 or Hoya Standard Filter NDX2?

    The HMC is the multi coated and best option.

    I'm selling :( My partner told me last night that the rainbows makes her ill. Arrghh... Going to be putting it in the For Sale Forum shortly... Anybody wants to advise how much I can ask for a H57 with 15 hours on the lamp, with carry case and all cables and brand new SPARE LAMP? It's really a disappointment to me that I have to sell it. As for the filter, I don't want to spend more money on a filter only for the problem to still be there.

    Yet another salutory lesson for all those considering one-chip DLP: Be SURE that you, and all those who will share your purchase with you, are happy with this technology. If you aren't sure - the safe choice is LCD - not perfect, but safe.

    I agree but it's not always so easy especially if one movie has no rainbows and the other does!
