I just received my PE7700 and spent some time calibrating it to D65 (not too much time because I was anxious to watch some movies on it). As a former owner of the PE8700, I would echo what others have said about the PE7700's impressive performance in light of its price.
As I get time, I will run a grayscale measurement on the various color temps (warm, normal, cool) and post the charts. I will also post my settings for a D65 grayscale and adjustments to the color decoder settings when the lamp has a few more hours on it (obviously, your mileage may vary).
One thing I would note is that sharpness should remain at 0 rather than the more common practice of adjusting sharpness to its lowest setting. Using the Accupel sharpness pattern at 720p, edge enhancement was obvious at +1 and the projector lost 1x1 pixel mapping with sharpness at -1. With sharpness at 0, there was 1x1 pixel mapping and no artifacts.
With its exceptional brightness (I'm using a 118-inch 16:9 screen), the PE7700 is a prime candidate for achieving better PQ using a color correction filter. I attached the Hoya filter from my PE8700 and was rewarded with better blacks, increased contrast ratio, and more accurate color. I need to recalibrate with the color correction filter, but I feel this relatively inexpensive tweak (a filter is $50-$70) has some real potential.
I'm trying to get a hold of the service manual, and will post more information as I have time to experiment with this great projector.
