Thanks for the info. I will post about how I get on when I have the PJ (dedicated room I guess won't be done until some time in Feb/March).I would try using a Spyder 5 facing the PJ for gamma and the i1pro2 for color, provided they don't provide widely different results (i.e. they are not too far off each other). You need to split the two steps, but you would get the best of both. Get the Spyder 5 Express, it's very cheap and there is no need to buy any of the higher models. Just make sure you check the calibration with the Discus trained to the i1pro2 afterwards. I tested 3 or 4 Spyder 5 and I sent them all back, they were widely inaccurate, some of them incurring a drop of 15% brightness after the autocal.
You're supposed to get the i1pro2 facing the screen with the JVC Autocal, but I haven't done any tests as it's not supported in the V6//V7 for our models.
Looking forward to reading your comments.
Also glad to see you got a Discus and an i1pro2 combo. I hope you enjoy them as much as I do
The Discus is a nice meter, lovely build with great low light, but it is much worse than an i1d3 without being profiled - I don't think yours was particularly bad; I reckon they are all like that judging by comments I received from another ex-Discus user. It seems it probably just isn't a very good match for the "standard observer" which I guess is why they have to have so many different profiles for only slightly different monitors.
Still glad I got it though, nothing can match it for low light until you spend 7 or 8 times the amount - so it "is what it is" I guess.
