Grayscale calibrated reasonably well, with an average Delta E of only 1.4 and nothing higher than 2.6. The RGB balance was also good and other than a bump at 50 IRE, was consistent across the whole IRE range. As with past JVC projectors, adjusting Gain has an effect on the total IRE range, whereas Offset has little effect on upper IREs. So, if you adjust Gain, then compensate for the adjusted gain effect with Offset, it works out pretty good.
Again, as with prior JVC projectors, I used the custom gamma of 2.4 to achieve an overall gamma of 2.2 or higher. This results in a pretty smooth gamma with an average of 2.22. Luminance tracking is quite good as well. Using the 2.4 gamma setting tends to crush blacks a little, so increasing the Brightness setting to 5 is necessary. This projector has some newly described gamma settings (as compared to past JVC projectors), but they appear to be similar to the previous A, B, C and D gamma settings.
