I plugged in a recently re-certified Eye One and argyll recognized it fine. I then calibrate on the white tile, and proceed to setting the monitor luminance. I just calibrated this display last evening with an I12 and set it to ~124 cd/m2, but the I1 Pro measured it at approximately ~178cd/m2. So I used the EyeOne match software with the I1 Pro to see what was going on, and that measured properly (~125 cd/ m2). I think the problem is that when I do a calibration of the I1 Pro in EyeOne Match, it turns the light on and takes a reflectance measurement of the white tile. The light does NOT come on when calibrating using Argyll, which I think I can convince myself would lead to the artificially high measurements. I tried calibrating on a dark surface and also with no calibration (-N) and got the same results. Any ideas? I pasted the dispcal command below and also the data Argyll reads for the instrument upon dispcal initialization.
