Thanks for your link Chad. I have a 980 to do tomorrow and a couple of 930s in the next few weeks. I have calibrated a 980 before but with a Lumagen Mini3d. Results were superb. Nevertheless, it’s with a bit of apprehension that I approach these next calibrations. I understand that there has been a substantial new firmware update for the 930(0). Do you know if this has improved performance of the calibration controls?
