To start I would use a calibration disk to get a good picture for your setup.
I have not calibrated mine, but I was using the THX mode for a while. I have since switched to using the Natural mode. It offers more pop and brightness which increases the perceived contrast even more. However, the contrast in THX was already amazing, I just wanted to see more pop. My current settings I have it running eco mode, super resolution at 2, no CFI, 7000k color temp, fine processing, performed LCD alignment, iris on fast mode, and everything else at 0.
I just finished watching Total Recall and the contrast was incredible. Very smooth 24p playback motion. The 24p felt a lot better than when I had the 8350.
Everything just pops!!
I too would like to know what everyone is using.
I agree with the above - most of the info is scattered all over with more talk about what's bad about the projector instead of what settings everyone is running.
Might be because the image doesn't need much adjusting at all. It already looks great to start off with.
I also don't like the fan noise with the lamp running in normal. The projector suddenly becomes noisy.
My screen is the Projecta 106" white screen from Best Buy, and there's plenty of brightness in eco mode at 106" with my white screen.
One thing I'd like to get and try is the LPE filter to get even more brightness out of this projector. Pair that with a slight grey screen and you would probably have a killer image for daytime ambient light.
