Hello all. I've read through lots of excellent postings, tried a few projectors and have narrowed down my choice for a new projector to the Optoma H57, Infocus 5700, or Sanyo Z3. The infocus 5700 had the edge, until I noticed what I think was a reference to it having no horizontal keystone or lens correction (infocus website is unclear on type of keystone correction). My projector will need to have some horizontal correction as it will be placed to the side of the sofa. Can anyone confirm whether the 5700 has horizontal correction, and if the H57 and Z3 have horizontal correction (I think the Z3 does). My other main issue has been brightness. My living room will have some ambient light. Reviews of the 5700 highlight its good performance in ambient light (c.f. Sim2 or other DLPs). Can anyone advise on relative brightness and performance of these 3 projectors in ambient light (will Z3, as a LCD, be the brightest?). I appreciate the H57 is not widely available yet, but a few posters have seen it at a London expo and I'd be grateful for their comments. Finally, one factor in the 5700's favour was the Faroudja DCDi deinterlacer. Does anyone know what de-interlacer the H57 has and how that compares to the Faroudja DCDi deinterlacer? Thanks. Grateful for any other views on these 3 projectors.
