Hartmut Scherer Posted February 22, 2007 Report Share Posted February 22, 2007 Since end of August 2006 I have been reading the posts in this forum. I am excited about PTE and the tools that it offers and of course I am looking forward to the final release of PTE 5.Recently I started to surf the Internet for a projector. My main purpose will be to present slide shows produced by PTE v.5. A secondary purpose will be to watch DVDs. Can anyone tell me if the rainbow artifacts from a DLP projector will show up in a PTE v.5 slide show with PZR effects? Quote Link to comment Share on other sites More sharing options...
alrobin Posted February 22, 2007 Report Share Posted February 22, 2007 Hartmut,Welcome to the Forum!If you get a good-quality DLP projector, you shouldn't notice these artifacts at all. I have a Mitsubishi WXGA projector, and they are not an issue.You will notice some "moire-pattern shimmer" on straight lines close together, but no more than on your computer monitor.

ksf Posted February 22, 2007 Report Share Posted February 22, 2007 Hi Al,I made a sequence with fog and mist effects where I had two semi-transparent PNG files moving at different speeds in slightly different directions to each other. At certain points along their path they produce a moire shimmer. So it's not just applicable to straight lines, it can apply to certain types of animated effects also.Hartmut - If you have the chance to try the projectors first then it may be worth making a short test sequence to see which projector works the best. Another make to look out for is "Plus". Quote Link to comment Share on other sites More sharing options...
alrobin Posted February 22, 2007 Report Share Posted February 22, 2007 If it possible prefer LCD or LCOS projector. Canon have a very good LCOS projector - the SX60.At one time the DLP projectors had a much better contrast ratio than the LCD, but I think that is changing some. The Mitsubishi DLP projector is quoted to have a 4000:1 contrast ratio, whereas the norm for other types used to be around 1000:1. For me, this is more important than pixel resolution. Low contrast ratio is the biggest drawback of some of the less-expensive models. However, this specification can also be somewhat misleading as different vendors measure it differently, and it varies with the setting of the projector.

Hartmut Scherer Posted February 25, 2007 Author Report Share Posted February 25, 2007 Thanks a lot. I highly appreciate all your advice. My preference is now to look for a "Lcos" projector. Quote Link to comment Share on other sites More sharing options...
