And the answer is yes - Reinstalled CEDP, it recognized the i1D2. Let me select which monitor to profile then I ran the second monitor with the same settings I'm using on the P221 (D50, 100nit ...). It came out with an average dE of .45 and a max of 1.54. Not too bad for a inexpensive monitor.
The proof, however, is in the visual results. Though I won't use the monitor for Soft Proofing (I will probably turn it off then) it is much closer visually and the colour shift is almost gone. The main difference is the P221W's colours are visually more saturated but I suspect this is due to it's wider gamut.
