VPL-VW1100ES Native 4K 3D SXRD Home Theater Projector

I have had the VPL-VW1000ES projector for almost 2 years now, and just recently got the upgrade to the VPL-VW1100ES which required replacement of the motherboard by a Sony tech, and addition of the 4k Sony player (and an extra $2,500). I have a > 200" high gain screen. In 2d, with the contrast maxed out, the brightness and color up, and lamp on full iris, it produces a gorgeous picture. 3D however is so dim, it is un-watchable. Even with all the settings for brightness maxed out, all except the brightest of scenes are dim. Animation tends to look a little better in 3d than live action, but it is still dim. Watching native 4k from the demos included in the 4k 2TB hard drive player is an eye-popping treat. Standing a nose away from the projection on the screen, no pixilation is visible, only the contour of the screen itself can be seen. This projector up-scales 1080p blurays to 4k, and they come out beautiful. The 4k movies available through the sony player however are no better than the blu-rays, so don't waist your money paying an extra $10 to $15 for the 4k versions. We will have to wait until some movies come out in native 4k to see any real difference.
