Pac兄所指高人系？我部x90只系用左出廠設定至今，請問x70經調教後有幾多%改善啊？

I am a X30 user so comment may or may not directly relate to post-calibration of X70/X90 but suspect they are close.

Pre - calibration setting: use Standard color space / File picture mode / 6500K color temperature / Custom 2.3 Gamma / turn off all noise reduction and CMD / lowest aperture (-15) / Standard HDMI input

After a pre-calibration profiling using Chromapure, my X30 on my HD130 screen show, as expected, over saturated color but not as bad as earlier models, and Gamma was too high for the lower IRE/grayscale, ie, 50 and below and going to more acceptable level in the 60 or higher IRE, also color gamut error, not too horrible but definitely need fixing.

It really shows that you NEED to calibrate this machine using proper software and not by eyes.  I don't have the pre and post file with me so I can't show anything, but in general the projector can track very good to the 6500K temperature and gamut accuracy and gamma performance once calibrated. Using an external video processor such as iScan or Lumagen would definitely help the X30 since it has no CMS.  For X70/90 I am not sure how well the CMS perform but it should do very well.

Have it calibrated for those who haven't.  The image depth is much better, color pops without over saturating, and much more 3 dimensional with impressive details and contrast especially in dark scenes.

I don't watch 3D at all but according to quite a few actual users in avsforum, if you are really into 3D, you might want to consider other brands, main issue is ghosting.
