Mike’s notes:  Grayscale calibrated pretty well, with an average Delta E of only 1.1.  Adjusting Gain ond Offset has a greater effect on the total IRE range than it should, so you end up with the lower IREs slightly high in red to keep the rest of the range more accurate.  As Stage (the brightest mode) is only 72 lumens more than User mode, there’s no need for a quick cal of a “bright” mode.  As seems to be normal for JVC projectors, gamma was too low in any of the presets (Normal was the high with an average gamma of 2.10), so I used the custom gamma.  The custom gamma started with the Normal preset, but I dropped the numbers by 15 up to 70%, and then -10 after that. 

The standard color gamut is decent and doesn’t have the oversaturated green that prior models had, but the secondaries are all off a little in hue (see CIE charts*).  Fortunately, the CMS works quite well and I was able to dial in the colors pretty well.  Overall, colors look very good.
