BenQ HT1075 Calibration

Mike's General Notes

I did a Quick Cal of Bright, but even a slight reduction of green causes the lumen output to drop more than 10% and does not improve the green cast enough to make it worth it in my opinion.  Considering you can get almost 2100 lumens in Standard mode, the extra 100 lumens you get by dropping the green in Dynamic is of little value.

Mike's Grayscale Calibration Notes

Grayscale by default in every mode but Bright (which uses the Lamp Native color temp instead of Normal like all of the other modes) was among the best I’ve seen.  As expected, Cinema mode had the best default grayscale, but Standard was close behind.  As you can see from the calibration settings, there was minimal adjustment to Gain and no adjustment to Offset needed to get an exceptional RGB balance.  Delta E was 2.4 or less from 20-100 IRE before calibration and improved to 1.0 or less from 20-90 IRE (with a maximum of 1.7 at 100 IRE), after calibration.  The 2.2 gamma setting provided a smooth gamma graph with an average of 2.18.
